Android Basics
1) Android Basics
Introduction:
Android is a software stack for mobile devices that includes an operating system, middleware and key applications. Google Inc. purchased the initial developer of the software, Android Inc., in 2005. Android's mobile operating system is based on the Linux kernel. Google and other members of the Open Handset Alliance collaborated on Android's development and release. The Android Open Source Project (AOSP) is tasked with the maintenance and further development of Android. The Android operating system is currently the world's best-selling Smartphone platform.
Android has a large community of developers writing applications ("apps") that extend the functionality of the devices. There are currently over 200,000 apps available for Android. Android Market is the online app store run by Google, though apps can also be downloaded from third-party sites. Developers write primarily in the Java language, controlling the device via Google-developed Java libraries.
The unveiling of the Android distribution on 5 November 2007 was announced with the founding of the Open Handset Alliance, a consortium of 80 hardware, software, and telecom companies devoted to advancing open standards for mobile devices. Google released most of the Android code under the Apache License, a free software and open source license.
The Android open-source software stack consists of Java applications running on a Java-based, object-oriented application framework on top of Java core libraries running on a Dalvik virtual machine featuring JIT compilation. Libraries written in C include the surface manager, OpenCore media framework, SQLite relational database management system, OpenGL ES 2.0 3D graphics API, WebKit layout engine, SGL graphics engine, SSL, and Bionic libc. The Android operating system, including the Linux kernel, consists of roughly 12 million lines of code including 3 million lines of XML, 2.8 million lines of C, 2.1 million lines of Java, and 1.75 million lines of C++.

Android Architecture
FEATURES OF ANDROID
Handset layouts The platform is adaptable to larger, VGA, 2D graphics library, 3D graphics library based on OpenGL ES 2.0 specifications, and traditional smartphone layouts.
Storage SQLite, a lightweight relational database, is used for data storage purposes
Connectivity Android supports connectivity technologies including GSM/EDGE, IDEN, CDMA, EV-DO, UMTS, Bluetooth, Wi-Fi (no connections through Proxy server and no Ad hoc wireless network), LTE, NFC and WiMAX.
Messaging SMS and MMS are available forms of messaging, including threaded text messaging and now Android Cloud To Device Messaging Framework(C2DM) is also a part of Android Push Messaging service.
Multiple Language Support Multiple languages are available on Android. The number of languages more than doubled for the platform 2.3 Gingerbread. Android lacks font rendering of several languages even after official announcements[citation needed] of added support (e.g. Hindi).
Web browser The web browser available in Android is based on the open-source WebKit layout engine, coupled with Chrome's V8 JavaScript engine. The browser scores a 93/100 on the Acid3 Test.
Java support While most Android applications are written in Java, there is no Java Virtual Machine in the platform and Java byte code is not executed. Java classes are compiled into Dalvik executables and run on the Dalvik virtual machine. Dalvik is a specialized virtual machine designed specifically for Android and optimized for battery-powered mobile devices with limited memory and CPU. J2ME support can be provided via third-party applications.
Media support Android supports the following audio/video/still media formats: WebM, H.263, H.264 (in 3GP or MP4 container), MPEG-4 SP, AMR, AMR-WB (in 3GP container), AAC, HE-AAC (in MP4 or 3GP container), MP3, MIDI, Ogg Vorbis, FLAC, WAV, JPEG, PNG, GIF (though earlier versions do not support animated GIFs, BMP.
Streaming media support RTP/RTSP streaming (3GPP PSS, ISMA), HTML progressive download (HTML5 <video> tag). Adobe Flash Streaming (RTMP) and HTTP Dynamic Streaming are supported by the Flash plugin. Apple HTTP Live Streaming is supported by RealPlayer for Mobile, and by the operating system in Android 3.0 (Honeycomb). Microsoft Smooth Streaming is planned to be supported through the awaited port of Silverlight plugin to Android.
Additional hardware support Android can use video/still cameras, touchscreens, GPS, accelerometers, gyroscopes, magnetometers, dedicated gaming controls, proximity and pressure sensors, thermometers, accelerated 2D bit blits (with hardware orientation, scaling, pixel format conversion) and accelerated 3D graphics.
Multi-touch Android has native support for multi-touch which was initially made available in handsets such as the HTC Hero. The feature was originally disabled at the kernel level (possibly to avoid infringing Apple's patents on touch-screen technology at the time). Google has since released an update for the Nexus One and the Motorola Droid which enables multi-touch natively.
Bluetooth Supports A2DP, AVRCP, sending files (OPP), accessing the phone book (PBAP), voice dialing and sending contacts between phones. Keyboard, mouse and joystick (HID) support is available through manufacturer customizations and third-party applications. Full HID support is planned for Android 3.0 (Honeycomb).
Video calling Android does not provide native video calling support, but some handsets have a customized version of the operating system that support it, either via the UMTS network (like the Samsung Galaxy S) or over IP. Video calling through Google Talk is available in Android 2.3.4 and later.
Multitasking Multitasking of applications is available.
Voice based features Google search through voice has been available since initial release. Voice actions for calling, texting, navigation, etc. are supported on Android 2.2 onwards.
Tethering Android supports tethering, which allows a phone to be used as a wireless/wired hotspot. Prior to Android 2.2 this was supported by third-party applications or manufacturer customizations.
Screen Capture Android does not currently support screenshot capture. This is supported by manufacturer and third-party customizations.

TouchScreen: ATMEL mXT224(AT42QT602240)
General Desciption
A 224-node highly configurable touchscreen controller that is part of the Atmel maXTouch product platform. An optimal and scalable architecture enables smart processing of a capacitive touch image to accurately regenerate and report the user’s interaction with the touchscreen. Multi-touch performance identifies and individually tracks touches and allows a range of built-in gestures to be reported to the host processor. The IC provides position data of 12-bit x 12-bit resolution, as well as information on the size and angle of touch. Position data is reported at >250Hz, providing fast and smooth finger tracking, making it suitable for use with demanding applications such as handwriting recognition. Due to the high signal-to-noise ratio (SNR) of up to 80:1, the device works well with fingertip touch and can also be used with a conductive stylus. It is designed to work in demanding, rapidly changing environments. Only the touchscreen area is touch-sensitive, allowing design freedom to place the chip on the main board or adjacent to the sensor. The device is ideally suited to mobile phone-sized touchscreens and can also be used on screens of up to 7", supporting single-touch or two-touch with a larger finger separation.

Custom ROM
A custom ROM is a fully standalone version of the OS, including the kernel (which makes everything run), apps, services, etc - everything you need to operate the device, except it's customized by someone in some way.
So what does the "customized" part mean? Since Android is open source, developers are free to take stock ROMs, modify them, strip them of garbage, optimize them, add things, and pretty much do whatever their imagination and skills allow.
Flashing
Flashing Process is basically, installing a new ROM/Kernel, Stock/Custom, via Odin.
Odin is a software used to flash ROM's to the phone in the Download Mode.
Odin used for Galaxy 3 is v4.252.
Steps to follow:
1) Install Samsung Kies
2) Connect phone to PC and let it detect and install drivers automatically.
3) Download Odin with ops file from here.
4) Extract them to some folder.
5) Run Odin as Administrator.
6) Odin will now open.
7) Put phone in download mode. (Vol Down + HOME + POWER)
8) Connect Phone to PC via USB and wait till Odin shows detected.
9) Select One Package.
10) Select .ops file and .tar file for flashing.
11) Press Start button.
12) Wait till the message box on odin shows the following message and phone reboots.
13) You have now successfully flashed new ROM / Kernel.
Rooting
Rooting is a process that allows users of cellphones and other devices running the Android operating system to attain privileged control (known as "root access") within Android's Linux subsystem, similar to jailbreaking on Apple devices running the iOS operating system, overcoming limitations that the carriers and manufacturers put on such phones.
Most retail devices running the Android operating system must be rooted in order to install custom versions of the Android system such as CyanogenMod. This is because in the stock configuration (unrooted), user-installed applications do not have direct access to the flash memory chip on the device and, thus, are not able to replace or modify the operating system itself. Rooting is also necessary for certain applications and widgets that require additional system and hardware rights such as for rebooting the phone, certain backup utilities, and other access to other hardware such as status LEDs. Rooting is also needed to disable or remove manufacturer-installed applications such as City ID. Rooting the phone typically also includes installing an application called Superuser that supervises which applications are granted root rights.
Steps to follow:
1) Download SuperOneClick - Download
2) Run SuperOneClick
3) Press on Root
4) It will show "Waiting for device"
5) Put your phone in USB Debugging Mode.
6) Connect to PC via USB Cable.
7) Press Yes, for the subsequent messages that follow
8) Done
Deodexing
WHAT IS AN ODEX FILE?
In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These ‘odex’ files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.
THEN COMES DEODEX
Deodexing is basically repackaging of these APKs in a certain way, such that they are reassembled into classes.dex files. By doing that, all pieces of an application package are put together back in one place, thus eliminating the worry of a modified APK conflicting with some separate odexed parts.
In summary, Deodexed ROMs (or APKs) have all their application packages put back together in one place, allowing for easy modification such as theming. Since no pieces of code are coming from any external location, custom ROMs or APKs are always deodexed to ensure integrity.
HOW THIS WORKS
For the more geeky amongst us, Android OS uses a Java-based virtual machine for running applications, called the Dalvik Virtual Machine. A deodexed, or .dex file contains the cache used by this virtual machine (referred to as Dalvik-cache) for a program, and it is stored inside the APK. An .odex file, on the other hand, is an optimized version of this same .dex file that is stored next to the APK as opposed to inside it. Android applies this technique by default to all the system applications.
Now, when an Android-based system is booting, the davlik cache for the Davlik VM is built using these .odex files, allowing the OS to learn in advance what applications will be loaded, and thus speeds up the booting process.
By deodexing these APKs, a developer actually puts the .odex files back inside their respective APK packages. Since all code is now contained within the APK itself, it becomes possible to modify any application package without conflicting with the operating system’s execution environment.
ADVANTAGES & DISADVANTAGES
The advantage of deodexing is in modification possibilities. This is most widely used in custom ROMs and themes. A developer building a custom ROM would almost always choose to deodex the ROM package first, since that would not only allow him to modify various APKs, but also leave room for post-install theming.
On the other hand, since the .odex files were supposed to quickly build the dalvik cache, removing them would mean longer initial boot times. However, this is true only for the first ever boot after deodexing, since the cache would still get built over time as applications are used. Longer boot times may only be seen again if the dalvik cache is wiped for some reason.
For a casual user, the main implication is in theming possibilities. Themes for android come in APKs too, and if you want to modify any of those, you should always choose a dedoexed custom ROM.
Steps to follow:
1) Download xUltimate - Download
2) Run Main.exe
3) Press N to continue
4) Press Y to continue
5) You should get a complete menu
6) Connect phone to PC in USB Debugging Mode
7) Run Option 1
8) Run Option 2
9) Run Option 3
10) Run Option 4
11) You Will now have deodexed apps and framework files in done_app and done_frame folders.
12) Copy these folders where you have your adb setup.
13) Run the following Code
Code:
adb -d shell "mount -o remount,rw /dev/block/stl6 /system"
adb -d shell "stop"
adb -d shell "rm /system/app/*.apk"
adb -d shell "rm /system/app/*.odex"
adb -d shell "rm /system/framework/*.jar"
adb -d shell "rm /system/framework/*.odex"
adb -d push done_app /system/app/
adb -d push done_frame /system/framework/
adb reboot
14) Your phone should reboot successfully, and you now have a deodexed ROM.

5) Kernel Basics
dhirend_6d said:
What Is a Kernel?
The UNIX kernel is the software that manages the user program's access to the systems hardware and software resources. These resources range from being granted CPU time, accessing memory, reading and writing to the disk drives, connecting to the network, and interacting with the terminal or GUI interface. The kernel makes this all possible by controlling and providing access to memory, processor, input/output devices, disk files, and special services to user programs.
Kernel Services
The basic UNIX kernel can be broken into four main subsystems:
Process Management
Memory Management
I/O Management
File Management
These subsystems should be viewed as separate entities that work in concert to provide services to a program that enable it to do meaningful work. These management subsystems make it possible for a user to access a database via a Web interface, print a report, or do something as complex as managing a 911 emergency system. At any moment in the system, numerous programs may request services from these subsystems. It is the kernel's responsibility to schedule work and, if the process is authorized, grant access to utilize these subsystems. In short, programs interact with the subsystems via software libraries and the systems call interface. We'll start by looking at how the UNIX kernel comes to life by way of the system initialization process.
System Initialization
System initialization (booting) is the first step toward bringing your system into an operational state. A number of machine-dependent and machine-independent steps are gone through before your system is ready to begin servicing users. At system startup, there is nothing running on the Central Processing Unit (CPU). The kernel is a complex program that must have its binary image loaded at a specific address from some type of storage device, usually a disk drive. The boot disk maintains a small restricted area called the boot sector that contains a boot program that loads and initializes the kernel. You'll find that this is a vendor specific procedure that reflects the architectural hardware differences between the various UNIX vendor platforms. When this step is completed, the CPU must jump to a specific memory address and start executing the code at that location. Once the kernel is loaded, it goes through its own hardware and software initialization.
Kernel Mode
The operating system, or kernel, runs in a privileged manner known as kernel mode. This mode of operation allows the kernel to run without being interfered with by other programs currently in the system. The microprocessor enforces this line of demarcation between user and kernel level mode. With the kernel operating in its own protected address space, it is guaranteed to maintain the integrity of its own data structures and that of other processes. (That's not to say that a privileged process could not inadvertently cause corruption within the kernel.) These data structures are used by the kernel to manage and control itself and any other programs that may be running in the system. If any of these data structures were allowed to be accidentally or intentionally altered, the system could quickly crash. Now that we have learned what a UNIX kernel is and how it is loaded into the system, we are ready to take a look at the four UNIX subsystems Process Management, Memory Management, Filesystem Management and I/O Management.
Process Management
The Process Management subsystem controls the creation, termination, accounting, and scheduling of processes. It also oversees process state transitions and the switching between privileged and nonprivileged modes of execution. The Process Management subsystem also facilitates and manages the complex task of the creation of child processes.
A simple definition of a process is that it is an executing program. It is an entity that requires system resources, and it has a finite lifetime. It has the capability to create other processes via the system call interface. In short, it is an electronic representation of a user's or programmer's desire to accomplish some useful piece of work. A process may appear to the user as if it is the only job running in the machine. This "sleight of hand" is only an illusion. At any one time a processor is only executing a single process.
Process Structure
A process has a definite structure (see Figure 19.1). The kernel views this string of bits as the process image. This binary image consists of both a user and system address space as well as registers that store the process's data during its execution. The user address space is also known as the user image. This is the code that is written by a programmer and compiled into an ".o " object file. An object file is a file that contains machine language code/data and is in a format that the linker program can use to then create an executable program.
Diagram of process areas.
The user address space consists of five separate areas: Text, Data, Bss, stack, and user area.
Text Segment The first area of a process is its text segment. This area contains the executable program code for the process. This area is shared by other processes that execute the program. It is therefore fixed and unchangeable and is usually swapped out to disk by the system when memory gets too tight.
Data Area The data area contains both the global and static variables used by the program. For example, a programmer may know in advance that a certain data variable needs to be set to a certain value. In the C programming language, it would look like:
Code:
int x = 15;
If you were to look at the data segment when the program was loaded, you would see that the variable x was an integer type with an initial value of 15.
Bss Area The bss area, like the data area, holds information for the programs variables. The difference is that the bss area maintains variables that will have their data values assigned to them during the programs execution. For example, a programmer may know that she needs variables to hold certain data that will be input by a user during the execution of the program.
Code:
int a,b,c; // a,b and c are variables that hold integer values.
char *ptr; // ptr is an unitialized character pointer.
The program code can also make calls to library routines like malloc to obtain a chunk of memory and assign it to a variable like the one declared above.
Stack Area The stack area maintains the process's local variables, parameters used in functions, and values returned by functions. For example, a program may contain code that calls another block of code (possibly written by someone else). The calling block of code passes data to the receiving block of code by way of the stack. The called block of code then process's the data and returns data back to the calling code. The stack plays an important role in allowing a process to work with temporary data.
User Area The user area maintains data that is used by the kernel while the process is running. The user area contains the real and effective user identifiers, real and effective group identifiers, current directory, and a list of open files. Sizes of the text, data, and stack areas, as well as pointers to process data structures, are maintained. Other areas that can be considered part of the process's address space are the heap, private shared libraries data, shared libraries, and shared memory. During initial startup and execution of the program, the kernel allocates the memory and creates the necessary structures to maintain these areas.
The user area is used by the kernel to manage the process. This area maintains the majority of the accounting information for a process. It is part of the process address space and is only used by the kernel while the process is executing(see Figure 19.2). When the process is not executing, its user area may be swapped out to disk by the Memory Manager. In most versions of UNIX, the user area is mapped to a fixed virtual memory address. Under HP-UX 10.X, this virtual address is 0x7FFE6000. When the kernel performs a context switch (starts executing a different process) to a new process, it will always map the process's physical address to this virtual address. Since the kernel already has a pointer fixed to this location in memory, it is a simple matter of referencing the current u pointer to be able to begin managing the newly switched in process. The file /usr/include/sys/user.h contains the user area's structure definition for your version of UNIX.
Diagram of kernel address space.
Process Table The process table is another important structure used by the kernel to manage the processes in the system. The process table is an array of process structures that the kernel uses to manage the execution of programs. Each table entry defines a process that the kernel has created. The process table is always resident in the computer's memory. This is because the kernel is repeatedly querying and updating this table as it switches processes in and out of the CPU. For those processes that are not currently executing, their process table structures are being updated by the kernel for scheduling purposes. The process structures for your system are defined in /usr/include/sys/proc.h.
Fork Process The kernel provides each process with the tools to duplicate itself for the purpose of creating a new process. This new entity is termed a child process. The fork() system call is invoked by an existing process (termed the parent process) and creates a replica of the parent process. While a process will have one parent, it can spawn many children. The new child process inherits certain attributes from its parent.
Process Run States
A process moves between several states during its lifetime, although a process can only be in one state at any one time. Certain events, such as system interrupts, blocking of resources, or software traps will cause a process to change its run state. The kernel maintains queues in memory that it uses to assign a process to based upon that process's state. It keeps track of the process by its user ID.
UNIX version System V Release 4 (SVR4) recognizes the following process run states:
Code:
- SIDLE This is the state right after a process has issued
a fork() system call. A process image has yet to be copied into memory.
- SRUN The process is ready to run and is waiting to be executed by the CPU.
- SONPROC The process is currently being executed by the CPU.
- SSLEEP The process is blocking on an event or resource.
- SZOMB The process has terminated and is waiting on
either its parent or the init process to allow it to completely exit.
- SXBRK The process is has been switched out so that another process can be executed.
- SSTOP The process is stopped.[/COLOR]
When a process first starts, the kernel allocates it a slot in the process table and places the process in the SIDL state. Once the process has the resources it needs to run, the kernel places it onto the run queue. The process is now in the SRUN state awaiting its turn in the CPU. Once its turn comes for the process to be switched into the CPU, the kernel will tag it as being in the SONPROC state. In this state, the process will execute in either user or kernel mode. User mode is where the process is executing nonprivileged code from the user's compiled program. Kernel mode is where kernel code is being executed from the kernel's privileged address space via a system call.
At some point the process is switched out of the CPU because it has either been signaled to do so (for instance, the user issues a stop signal--SSTOP state) or the process has exceeded its quota of allowable CPU time and the kernel needs the CPU to do some work for another process. The act of switching the focus of the CPU from one process to another is called a context switch. When this occurs, the process enters what is known as the SXBRK state. If the process still needs to run and is waiting for another system resource, such as disk services, it will enter the SSLEEP state until the resource is available and the kernel wakes the process up and places it on the SRUN queue. When the process has finally completed its work and is ready to terminate, it enters the SZOMB state. We have seen the fundamentals of what states a process can exist in and how it moves through them. Let's now learn how a kernel schedules a process to run.
Process Scheduler
Most modern versions of UNIX (for instance, SVR4 and Solaris 2.x) are classified as preemptive operating systems. They are capable of interrupting an executing a process and "freezing" it so that the CPU can service a different process. This obviously has the advantage of fairly allocating the system's resources to all the processes in the system. This is one goal of the many systems architects and programmers who design and write schedulers. The disadvantages are that not all processes are equal and that complex algorithms must be designed and implemented as kernel code in order to maintain the illusion that each user process is running as if it was the only job in the system. The kernel maintains this balance by placing processes in the various priority queues or run queues and apportioning its CPU time-slice based on its priority class (Real-Time versus Timeshare).
Memory Management
Random access memory (RAM) is a very critical component in any computer system. It's the one component that always seems to be in short supply on most systems. Unfortunately, most organizations' budgets don't allow for the purchase of all the memory that their technical staff feel is necessary to support all their projects. Luckily, UNIX allows us to execute all sorts of programs without, what appears at first glance to be, enough physical memory. This comes in very handy when the system is required to support a user community that needs to execute an organization's custom and commercial software to gain access to its data.
Memory chips are high-speed electronic devices that plug directly into your computer. Main memory is also called core memory by some technicians. Ever heard of a core dump? (Writing out main memory to a storage device for post-dump analysis.) Usually it is caused by a program or system crash or failure. An important aspect of memory chips is that they can store data at specific locations called addresses. This makes it quite convenient for another hardware device called the central processing unit (CPU) to access these locations to run your programs. The kernel uses a paging and segmentation arrangement to organize process memory. This is where the memory management subsystem plays a significant role. Memory management can be defined as the efficient managing and sharing of the system's memory resources by the kernel and user processes.
Memory management follows certain rules that manage both physical and virtual memory. Since we already have an idea of what a physical memory chip or card is, we will provide a definition of virtual memory. Virtual memory is where the addressable memory locations that a process can be mapped into are independent of the physical address space of the CPU. Generally speaking, a process can exceed the physical address space/size of main memory and still load and execute.
The systems administrator should be aware that just because she has a fixed amount of physical memory, she should not expect it all to be available to execute user programs. The kernel is always resident in main memory and depending upon the kernel's configuration (tunable-like kernel tables, daemons, device drivers loaded, and so on), the amount left over can be classified as available memory. It is important for the systems administrator to know how much available memory the system has to work with when supporting his environment. Most systems display memory statistics during boot time. If your kernel is larger than it needs to be to support your environment, consider reconfiguring a smaller kernel to free up resources.
We learned before that a process has a well-defined structure and has certain specific control data structures that the kernel uses to manage the process during its system lifetime. One of the more important data structures that the kernel uses is the virtual address space (vas in HP-UX and as in SVR4. For a more detailed description of the layout of these structures, look at the vas.h or as.h header files under /usr/include on your system.).
A virtual address space exists for each process and is used by the process to keep track of process logical segments or regions that point to specific segments of the process's text (code), data, u_area, user, and kernel stacks; shared memory; shared library; and memory mapped file segments. Per-process regions protect and maintain the number of pages mapped into the segments. Each segment has a virtual address space segment as well. Multiple programs can share the process's text segment. The data segment holds the process's initialized and uninitialized (BSS) data. These areas can change size as the program executes.
The u_area and kernel stack contain information used by the kernel, and are a fixed size. The user stack is contained in the u_area; however, its size will fluctuate during its execution. Memory mapped files allow programmers to bring files into memory and work with them while in memory. Obviously, there is a limit to the size of the file you can load into memory (check your system documentation). Shared memory segments are usually set up and used by a process to share data with other processes. For example, a programmer may want to be able to pass messages to other programs by writing to a shared memory segment and having the receiving programs attach to that specific shared memory segment and read the message. Shared libraries allow programs to link to commonly used code at runtime. Shared libraries reduce the amount of memory needed by executing programs because only one copy of the code is required to be in memory. Each program will access the code at that memory location when necessary.
When a programmer writes and compiles a program, the compiler generates the object file from the source code. The linker program (ld) links the object file with the appropriate libraries and, if necessary, other object files to generate the executable program. The executable program contains virtual addresses that are converted into physical memory addresses when the program is run. This address translation must occur prior to the program being loaded into memory so that the CPU can reference the actual code.
When the program starts to run, the kernel sets up its data structures (proc, virtual address space, per-process region) and begins to execute the process in user mode. Eventually, the process will access a page that's not in main memory (for instance, the pages in its working set are not in main memory). This is called a page fault. When this occurs, the kernel puts the process to sleep, switches from user mode to kernel mode, and attempts to load the page that the process was requesting to be loaded. The kernel searches for the page by locating the per-process region where the virtual address is located. It then goes to the segments (text, data, or other) per-process region to find the actual region that contains the information necessary to read in the page.
The kernel must now find a free page in which to load the process's requested page. If there are no free pages, the kernel must either page or swap out pages to make room for the new page request. Once there is some free space, the kernel pages in a block of pages from disk. This block contains the requested page plus additional pages that may be used by the process. Finally the kernel establishes the permissions and sets the protections for the newly loaded pages. The kernel wakes the process and switches back to user mode so the process can begin executing using the requested page. Pages are not brought into memory until the process requests them for execution. This is why the system is referred to as a demand paging system.
The memory management unit is a hardware component that handles the translation of virtual address spaces to physical memory addresses. The memory management unit also prevents a process from accessing another process's address space unless it is permitted to do so (protection fault). Memory is thus protected at the page level. The Translation Lookaside Buffer (TLB) is a hardware cache that maintains the most recently used virtual address space to physical address translations. It is controlled by the memory management unit to reduce the number of address translations that occur on the system.
Input and Output Management
The simplest definition of input/output is the control of data between hardware devices and software. A systems administrator is concerned with I/O at two separate levels. The first level is concerned with I/O between user address space and kernel address space; the second level is concerned with I/O between kernel address space and physical hardware devices. When data is written to disk, the first level of the I/O subsystem copies the data from user space to kernel space. Data is then passed from the kernel address space to the second level of the I/O subsystem. This is when the physical hardware device activates its own I/O subsystems, which determine the best location for the data on the available disks.
The OEM (Original Equipment Manufacture) UNIX configuration is satisfactory for many work environments, but does not take into consideration the network traffic or the behavior of specific applications on your system. Systems administrators find that they need to reconfigure the systems I/O to meet the expectations of the users and the demands of their applications. You should use the default configuration as a starting point and, as experience is gained with the demands on the system resources, tune the system to achieve peak I/O performance.
UNIX comes with a wide variety of tools that monitor system performance. Learning to use these tools will help you determine whether a performance problem is hardware or software related. Using these tools will help you determine whether a problem is poor user training, application tuning, system maintenance, or system configuration. sar, iostat, and monitor are some of your best basic I/O performance monitoring tools.
1) sar The sar command writes to standard output the contents of selected cumulative activity counters in the operating system. The following list is a breakdown of those activity counters that sar accumulates.
* File access
* Buffer usage
* system call activity
* Disk and tape input/output activity
* Free memory and swap space
* Kernel Memory Allocation (KMA)
* Interprocess communication
* Paging
* Queue Activity
* Central Processing Unit (CPU)
* Kernel tables
* Switching
* Terminal device activity
2) iostat Reports CPU statistics and input/output statistics for TTY devices, disks, and CD-ROMs.
3) monitor Like the sar command, but with a visual representation of the computer state.
RAM I/O
The memory subsystem comes into effect when the programs start requesting access to more physical RAM memory than is installed on your system. Once this point is reached, UNIX will start I/O processes called paging and swapping. This is when kernel procedures start moving pages of stored memory out to the paging or swap areas defined on your hard drives. (This procedure reflects how swap files work in Windows by Microsoft for a PC.) All UNIX systems use these procedures to free physical memory for reuse by other programs. The drawback to this is that once paging and swapping have started, system performance decreases rapidly. The system will continue using these techniques until demands for physical RAM drop to the amount that is installed on your system. There are only two physical states for memory performance on your system: Either you have enough RAM or you don't, and performance drops through the floor.
Memory performance problems are simple to diagnose; either you have enough memory or your system is thrashing. Computer systems start thrashing when more resources are dedicated to moving memory (paging and swapping) from RAM to the hard drives. Performance decreases as the CPUs and all subsystems become dedicated to trying to free physical RAM for themselves and other processes.
This summary doesn't do justice, however, to the complexity of memory management nor does it help you to deal with problems as they arise. To provide the background to understand these problems, we need to discuss virtual memory activity in more detail.
We have been discussing two memory processes: paging and swapping. These two processes help UNIX fulfill memory requirements for all processes. UNIX systems employ both paging and swapping to reduce I/O traffic and execute better control over the system's total aggregate memory. Keep in mind that paging and swapping are temporary measures; they cannot fix the underlying problem of low physical RAM memory.
Swapping moves entire idle processes to disk for reclamation of memory, and is a normal procedure for the UNIX operating system. When the idle process is called by the system again, it will copy the memory image from the disk swap area back into RAM.
On systems performing paging and swapping, swapping occurs in two separate situations. Swapping is often a part of normal housekeeping. Jobs that sleep for more that 20 seconds are considered idle and may be swapped out at any time. Swapping is also an emergency technique used to combat extreme memory shortages. Remember our definition of thrashing; this is when a system is in trouble. Some system administrators sum this up very well by calling it "desperation swapping."
Paging, on the other hand, moves individual pages (or pieces) of processes to disk and reclaims the freed memory, with most of the process remaining loaded in memory. Paging employs an algorithm to monitor usage of the pages, to leave recently accessed pages in physical memory, and to move idle pages into disk storage. This allows for optimum performance of I/O and reduces the amount of I/O traffic that swapping would normally require.
NOTE: Monitoring what the system is doing is easy with the ps command. ps is a "process status" command on all UNIX systems and typically shows many idle and swapped-out jobs. This command has a rich amount of options to show you what the computer is doing.
I/O performance management, like all administrative tasks, is a continual process. Generating performance statistics on a routine basis will assist in identifying and correcting potential problems before they have an impact on your system or, worst case, your users. UNIX offers basic system usage statistics packages that will assist you in automatically collecting and examining usage statistics.
You will find the load on the system will increase rapidly as new jobs are submitted and resources are not freed quickly enough. Performance drops as the disks become I/O bound trying to satisfy paging and swapping calls. Memory overload quickly forces a system to become I/O and CPU bound.
Filesystem Concept
Filesystem is the collection place on disk device(s) for files. Visualize the filesystem as consisting of a single node at the highest level (ROOT) and all other nodes descending from the root node in a tree-like fashion (see Figure 19.5) . The second meaning will be used for this discussion, and Hewlett Packard's High-performance Filesystem will be used for technical reference purposes.
Diagram of a Android' s hierarchical filesystem.
The superblock is the key to maintaining the filesystem. It's an 8 KB block of disk space that maintains the current status of the filesystem. Because of its importance, a copy is maintained in memory and at each cylinder group within the filesystem. The copy in main memory is updated as events transpire. The update daemon is the actual process that calls on the kernel to flush the cached superblocks, modified inodes, and cached data blocks to disk. The superblock maintains the following static and dynamic information about the

About first impression
My first impression of the device was so good. I really feel that the device materials and quality is distinct that other devices i tested.
There is lots of details that make a difference, from the device design, or the software included, or the customization made on the system, etc.
The first time you boot the device, you get a screen to register an iMuch account. This is not required really, but you can do these steps to gain access for Much services (note: most in chinese). In my tests, i remove my Much account, and i can use the device without problems.
(First boot)
There is a icon called Much Helper, that really is a quick guide to use the device, that is so interesting and helpful (this come in english), and show you in short steps the main features of the device and how to use.
Is really nice get a device like this that manufacturer take care about heir users, and provide ways to get familiar and comfortable with the device like this (and in english, a common language).
Another thing that i get may attention is that this device come with no much bloatware, and the games listed are to download from the google playstore (instead of a separated store with software from a non clear origin)
Most of this games are free, or demo versions.(and i thanks for it, because the system come with no unecessary software pre-installed)
Product information
According with the manufacturer, or searching info on web pages, we can found many sources of information about the device and sometimes these information may be not consistent (may be different from one web page to other), and this may cause some confusion for anybody that wants to get info about this product.
On this section i will post the info i get from the manufacturer (or is not possible, the web page that i consider more reliable), listing only the relevant points for a tech analysis of the product, and omit these points that don´t get any relevant info about the device (as many time we found on many pages, things such video capabilities, mail capabilities, etc, that really are software based features that we can install on the device, and not a real feature of the device itself)

ClockWorkMod Recovery (Custom Recovery)
Android have a special mode called Recovery, that is used many times to recover the device if this have problems to run properly, but there exist an alternative Custom Recovery that add a lot of new functionality and tools, and one of the most popular is one called ClockWorkMod Recovery.
There is a full functional version of this recovery that run on this device.
One of the most important features of this custom recovery, is the NANDROID generation, a way to generate a full backup of the nand (where the operating system resides) to a directory, and can be used as a recovery point for the device in case of semi-brick, or simply if you want to get a clean firmware on it.
Take note that this backup (nandroid) is a image of the NAND, this means, there will be stored all your configs, users, passwords, accounts, etc. Is a good idea to get a clean firmware insatlled on the device, and install and configure all your base programs (file admins, cloud services, google account, etc) and then get a nandroid for your personal use. When you get back to this image/backup, you will get a clean and configured system, saving lot of time on basic configurations and installing basic software.
The installation of CWM on this device is easy. For this, i follow the next thread on XDA forum:
How to install CWM on most rooted mtk devices
This method is based on Rua1 tool (a russian guy that develop a specific MTK took), and i will try to explay step by step.
First, you need the drivers ADB installed on the system. If you don´t get yet, then download and install PDANet (for windows, there is the 4.12 installer).
Then install PDANet, and when the program ask for connecting the device (USB), connect your Much.
Program will install drivers (if ask to you, select "other manufacturer" for generic drivers)
When you get installed this program, then go and download "MTK Droid Root & Tools | MediaTek Android Smartphone" ver 2.4.8 (from this thread on XDA)
Run the program. If the antivirus or firewall warning about a unknown thread, ignore it.
The program will run adb and connect with your device. No matter if you set root for ADB and Apps in System Settings, the program will inform that the device is not fully rooted. (there is a yellow rectangle)
Press ROOT button.
When finished, the rectangle will be green
(I will do a copy paste from XDA thread, because is well explained what you must to do)
Click on the tab 'root,backup,recovery' and select 'to use boot from phone' then click on 'recovery and boot' and shortly after a dialogue box will appear asking if you want to 'make cwm recovery automatically' click yes
System start to generate the CWM version.
Is possible that the tool show a dialog with a warning "ATENTION! There is a probability to damage the boot block!". Select "Yes"

About Battery
Some words i must to say about this point. This device is the first handheld gaming console that i forgive to take care constantly about battery level. In fact, using as a normal smartphone and as a gaming console, is a heavy use for me, more than my normal smartphone (i like to use a Motorola Razr), and my phone, only as phone, battery is not longer than Much device.
I don´t know how many hours it can be working, but i´m sure is enough for most of users that want a good duration.
Check the following screenshots:
These 3 screenshots was taken when i get in home, in night (well, really when i remember to take these screenshots)
The most important of these screenshots, are that the device was working as normal usage, with WIFI enabled, one SIM card enabled, and most time (when i´m in train or bus) with Bluetooth enabled (for bluetooth audio), with all normal options for a smartphone standard enabled (GPS, Vibration, etc), and most important, playing normally, and the battery, well, you can see the images. For this reason i can mention that i forgot to check constantly the battery level, to calculating how many time i can play, or anything.
And of course, the battery is replaceable, then if you really need more battery duration, simply buy another battery pack, and carry with you to replace when you go out of power.
Final words
Apologize for the mistakes i did writing in english. As many of you know, this is not my natural language, but i did my best to try to bring to you a readable and understandable article that, sincerely, i hope is useful.
And remember this is not a full article review. It is only a Summary.

Kirisakura-Kernel for the Rog Phone 3
Hello everyone,
To keep it short: Here is Kirisakura - Kernel for the Rog Phone 3 aka OBIWAN.
I would appreciate if everybody that flashes the kernel, reads at least once through this opening post and the following ones.
Kirisakura - Kernel is designed to bring a handful of beneficial features to the device, while ensuring excellent performance and smoothness to get you safely through the day!
This project aims to keep most of the subsystems updated, way ahead of the stock kernel, thereby improving security and performance, while keeping stability as the foucs during testing! This includes Linux-Stable, CAF-Upstream and kernel/common.
Kernel Control Flow Integrity (Kernel-CFI), which is achieved by linking the kernel with LLD and Link Time Optimization (LTO), more precisely ThinLTO, are quite unique security features. In fact this, alongside Kirisakura-Kernel for the OnePlus 8 Pro, may be (and probably is) the first 4.19 msm kernel with a fully working Kernel-CFI implementation and CFI-Violations fixed on a smartphone.
The only kernels made by OEMs offering this security feature are the ones for the Pixel 3 and Pixel 4 devices.
The recently released Kirisakura-Kernel for the OnePlus 8 Pro was featured on the XDA-Portal due to the inclusion of CFI. The featured article explains CFI in great details, is easy to understand and definitely worth to read.
Another security feature is Shadow Call Stack (SCS). Similar to CFI, only the Pixle 3 and 4 Kernel use this security feature.
SCS is another security patchset that is aimed at preventing attacks via return oriented programming (ROP).
ROP is a technique where the attacker gains control of the kernel stack to overwrite function return addresses and redirect execution to carefully selected parts of existing kernel code.
If you´re interested here are a few good links:
Google Security Blog explaining SCS.
LLVM doc about SCS
Android DOCs documenting SCS
If reading about upstream in the paragraph above got you curious,have a read about Linux-Stable and why it is important here. The stable-process is not the same for every subsystem, but the general idea, rule of thumb and benefits are applicable for other subsystems as well.
Quick explanation of CAF-Upstream. CAF is short for Codeaurora-Forums. This is the place where development from Qualcomm for their SoCs happens. This includes the Snapdragon 865/+ that´s built into the different SKUs of the Rog Phone 3.
The kernel-bases available on the Codeaurora-Forums, are basically the foundations OEMs use, to build their own kernel additions on top for devices featuring Qualcomm SoCs.
The Qualcomm developers push regular updates to the bases of the different SoCs, a bit similar to how Linux-Upstream works. OEMs usually stop updating the initial base after the phone is released.
This kernel focuses amongst the other features to provide the latest CAF-Updates merged in a regular manner, to provide updates, improvements and enhancements for SoC specific drivers and subsystems! This might take a while, because a lot of device specific testing is done on my end to ensure stability.
The kernel includes a lot of improvements and contributions from other developers as well. Without this kernel would not exist.
I´d like to mention @tbalden ´s excellent CleanSlate features at this place. They improve usability by a big margin for me personally. The highly customizable sweep to sleep implementation (adjustable to different navigation settings), long tap to bring down status bar (very useful on a big device), backlight dimmer and notification reminder are very useful features that I use personally every day.
Another big part of improvements originate from @arter97´s, @kdrag0n´s and @Sultanxda´s work. Many others contributed in some way or another to this kernel.
A big thanks to all of them at this place!

Flashing Guide, Download and Changelog
A description how to flash the kernel, links for download and a changelog can be found in the second post!
Contributors
Freak07
Source Code: https://github.com/freak07/Kirisakura_OBIWAN
Version Information
Status: Stable
Requirements
- unlocked Bootloader
- USB-Debugging in developer options enabled
- latest adb and fastboot binaries
- working adb and fastboot environment
- latest magisk stable root environment
- a backup of boot.img and dtbo.img to be able to restore to stock.
How to flash the Kernel:
1. Download the latest kernel.zip and make sure you have properly updated to the latest matching Asus Stock-Firmware. When the Rog 3 receives an update it takes Asus a while to release the source code for the new OS and me a while to build a new kernel. If you don´t want to face any issues, wait until I either release an updated kernel or give green light because there were no kernel changes.
Always make sure to run the firmware the kernel is built for!
1a. Optional: While it may not be necessary all times, you may want to restore stock boot.img as well as dtbo.img, re-root with magisk and optionally install twrp.zip if coming from another kernel. Before reporting issues make sure you do that! Thank you!
2. Make sure to meet all the requirements listed above.
3. Flash the kernel.zip via latest EXKM or FKM app, or TWRP and do a full reboot.
4. Reboot and profit. Set CleanSlate features as you desire by installing both apps and choose according to your liking.

FAQ
F.A.Q:
Question: Why does the kernel version show as "unavailable" in settings after flashing it.
Answer: Asus does not allow for custom kernel names in their settings. If the kernel string doesn´t fit their regex, it will display as unavailable there. Nothing can be done about it. Use a kernel manager to check the kernel version.
Question: Is root preserved when flashing this kernel?
Answer: Yes, the AnyKernel.zip will detect root and keep it.
Question: How do I return back to stock or another kernel.
Answer: Extract boot.img as well as dtbo.img from matching firmware you are on and flash the extracted boot.img and dtbo.img via fastboot. If you want to keep root flash back the magisk_patched_boot.img. Or dirty flash your rom.
Question: Why is having Magisk installed mandatory for this kernel?
Answer: Android 10s changes to partitions, doesn´t allow files in system/ and vendor/ to be replaced. This kernel is very far from the stock kernel. To account for this I can´t force load the stock kernel-modules for certain drivers as it happens on kernels that are closer to stock.
Instead we use Magisks function to overlay certain files during boot. Without a working Magisk environment the kernel cannot function.
Question: I have a phone that is converted from CN to WW and now there´s a warning from hardwarestub. Can I hide it?
Answer: Yes, I created a Magisk Module for those that want to hide the notification, so nobody needs to rely on paid apps.
The Magisk module can be found attached to this post.
Please note that refresh rate can´t be changed when the module is flashed. To able to change refresh rate or to remove the module, simple remove it in Magisk Manager and do a full reboot. I´ll attach it to the third post on this thread. There will be no support for this module from my side and no other support for converted devices.
Question: How to report bugs properly?
Answer: Have a look at post #3 in the linked thread. The linked guide is a pretty good starting point.
Before reporting any bug make sure you´re running on a stock configuration. That´s means you´re not using any mods, tweaks in kernel managers or other root tweaks , magisk modules, scripts or other modifications that alter various functions like sound mods, data traffic, sleeping behaviour, scheduler, magical battery tweaks etc.
Try to describe the issue as detailed as possible! Give your exact setup, like rom, magisk version, kernel version.
Is the issue reproducible? Does it happen frequently?
Provide logs, otherwise debugging is a lot harder. If you can already reproduce the issue and provide logs it greatly limits the amount of time I have to spent until I figure out how to reproduce it.
If the device force reboots/randomly reboots (that means you see the bootloader unlocked screen!) provide a .zip with the contents of sys/fs/pstore.
If the issue happens while the device is running provide a dmesg plus a logcat that you take while/shortly after the issue happens. This will log what´s running in the current session. Try to be as detailed as possible what´s happening when the issue appears. It will also help me in reading the log!
CleanSlate Features and how to use them
CleanSlate Features and how to use them
This kernels offers its users the possibility to use CleanSlate features. CleanSlate-Kernel is developed by @tbalden.
CleanSlate kernel follows a different approach than Kirisakura-Kernel.
We know each other well over the years now and often have worked together.
For more information about CleanSlate visit @tbaldens CleanSlate thread on the Rog 3 Forums linked here.
The CleanSlate features add a lot of flexibility to a device. That´s why I like to include the features in my kernel.
Notifications Reminder, Flashlight Notifications, Turn Phone to sleep and a very advanced sweep to sleep interface that works well with Android 10 Gestures.
We decided to transform Brightness Dimmer and FPS-Override into CleanSlate accessible features as well.
That allows users to easily control these features with the CleanSlate apps.
CleanSlate features are easily accessible via the CleanSlate Configuration app. The Cleanslate Companion app provides a userspace backend for the kernel and is required for some features.
Make sure to install both of these apps, when flashing my kernel and you want to utilize these features.
The apps ask for some permissions. Enable them and do a full reboot to make sure everything is playing nicely
that´s how the companion app will look after enabling it.
https://photos.app.goo.gl/x6sFJc5cUFT9Q7U47
It´s needed for userspace related features, like double tap swipe area for notification pull down.
Every section of the Configuration App has different settings. Basic, Advanced and Preset. You can click on these buttons to change between them.
Advanced will offer you more customization if available.
See the screenshots here:
https://photos.app.goo.gl/avPsiHHrzPwpMqMC8
To change settings, change them according to your liking and hit the "Save" Button. It is the second from the bottom right and will be greyed out if your settings are currently applied.
As you can see in the following screenshot:
https://photos.app.goo.gl/qaFKfLbfwUuyHW717
Brightness Dimmer is enabled, FPS override is set to 144FPS on low brightness. Power button is blocked in pocket and screen gets disabled when putting the phone face down on a desk.
You should be able to find both apps for free on the CleanSlate thread. However if you benefit from the features, think about getting the premium apps on the playstore to give a little bit back to @tbalden.
I hope this post might help some
Excellent! Keep it up

U aswell... Both of you keep up the great job
This is amazing, can't wait for the others to try and read their reviews..
just a small heads up before anybody complains.
We, @tbalden and me, just noticed a bug went unnoticed during our previous testing.
If you flashed this kernel or CleanSlate-Kernel, have the CleanSlate config app installed and Backlight dimmer enabled in the CleanSlate Config app. Make sure to keep the screen on for 3-4 minutes after rebooting your phone and the boot process finished.
Otherwise your screen will stay black. Display-Panel driver doesn´t seem to like our mod at the moment.
After keeping the screen on for 3-4 minutes the bug will not be triggered and you can use the phone as you wish.
Sorry for the inconvenience
The issue will soon be resolved in a new update

Also just start the app manually on reboot, as a workaround.
Coming here from your OG Pixel kernel. Is this kernel for 2007.47 or 2007.32?

Nice to see you made the jump! Must be a hell of an upgrade on your side!
the .47 sources are merged. I´m using it on .47 at the moment.
I guess you can just give it a try and check if it boots/works on .32. If you decide to do so, it would be nice if you could report back here. It might help others
Make sure to have a PC with working fastboot environment nearby and a boot.img handy.
In case it doesn´t work, just force the phone to power down by holding power button plus volume down, once it powers off, keep holding power and volume up to boot to bootloader.
Connect to side port and flash your backup boot.img via fastboot. Always make sure to flash the matching boot.img for your firmware.
Hey guys and girls,
Here´s the fix that solves the black screen issue, that occurred when the screen was off while Brightness Dimmer got activated via CleanSlate Config App on boot.
It wasn´t detected immediately, because usually the screen of my device is on when I boot the phone as to check the logs and ensure everything is working
Now everything is working, so just flash the kernel and enjoy I´ll do a post soon, explaining the features a bit more for people unfamiliar with how the CleanSlate features work.
I´d advise everybody to read the instructions in the OP and follow them. They are written for a reason, because they ensure everything will be working as expected.
Kernel is made for the latest stock rom from Asus, you must update your phone to the most recent Asus update, before flashing the kernel.
Enjoy!
Changelog:
- Fix Screen not being able to wake up on a certain condition.
I wish you all a nice day/evening!

Instructions how to flash the kernel can be found in the OP!
But look at this post too
To make use of the CleanSlate features, like force FPS on Low Brightness or Brightness Dimmer you need to download both CleanSlate Apps:
Please take a look at the CleanSlate thread for CleanSlate features. I will provide the link to the free to download apps here.
If you use the CleanSlate features and benefit over time, maybe think about giving something back to @tbalden and purchase them from PlayStore.
CleanSlate Configuration App (to control the features):

CleanSlate Companion App (provides additional information from userspace for CleanSlate Kernel features to work correctly)

I'm using Tencent Version, but already fully converted to Global ROM. Updated from 32 to 47. Already flash your kernel. It's works.

If you mean CN to Global ROM, Global has no China bloatware. If you mean 32 to 47, here the changelog from Asus website.
1.Added “Quick launch camera” option in System Settings->Advanced
2.Added “Navigation blocking” feature for Game Genie which disables system gesture operations to avoid accidental touches in games.
3.Improved multi-touch when three or more fingers simultaneously touch the screen in games.
4.Fixed a problem with insensitive multi-finger touch response when playing PUBG

Just to steer this a bit in the right direction. This isn´t directed towards anybody in particular it´s just a general reminder what this thread is about.
There is no need to review the kernel. The kernel offers exactly what is described in the first post of this thread.
My advice is to read the description in the OP. All changes are explained in great detail there. Look around XDA, most OPs are kept way shorter with less explanations.
If you´re not into technical details, use google when descriptions or terms are unclear to you.
This is primarily a development focused thread. That´s why it is in the development section.
If there are issues when using the kernel or its features, provide logs and I will be glad to help you. If there are questions or things unclear, ask and I will try to answer. But I expect people to put in a bit of effort.
If you expect a review like, flashing this kernel causes my phone to use more or less battery as the stock kernel, you may want to re-read the OP on what to expect. I generally don´t like to see this in my threads.
Just to give an example that a "review" will never be applicable to each user:
Everybody uses their phone different. So certain changes to the scheduler may benefit user A, while they don´t benefit user B.
There is no need for a review. Just flash the kernel and try for yourself.
It´s very easy and straightforward to flash the kernel. And it´s also easy to return back to the stock kernel. If you don´t like it describe your problem as detailed as possible, as pictured in the FAQ and I will take a look at it or consider it.
Usually post like: "this kernel reduces my battery life by xyz" will just be ignored
It´s covered in the FAQ how to do all of this.
This is also a general reminder to everyone Let´s keep this thread development related and I hope this will turn out to be a good project!
I´m really looking forward to it. This phone is an absolute beast and so far I really enjoy using it.
For people a bit unfamiliar how everything works I plan to soon post a little guide on how to use the CleanSlate features.
Have a nice day everybody.
Here´s a small tutorial for CleanSlate features:

Hopefully it will help some, that are not yet familiar with these.
I wish everybody a nice weekend.
Amazing work. Low battery temp while fast charging. Now I can just leave my phone with 30w charger without worry.
Do you have Telegram Channel?
I thought its not working after i flash but suddenly all the features is needed an app CleanState Config/Companion i downloaded it and it works the 144hz in 0 brightness nice2. i will use this kernel as my daily bases.
I turn on the facedown to table to turnoff the screen or vibrate but its not working for me.
Edit: Its working btw there is a 1 sec delay after facedown so far so good.
