Hi,
I've searched a lot and nothing found as solution for my Superpad device so below something like solution.
In example below I'm using Superpad Chinese pad, sure some of this action could be applied to any other android devices.
If you experienced with silent mic problem in android system, you can perform fix in few ways (sure only for rooted device):
1. Way to fix through alsa. Launch terminal and type:
Code:
$ su
- find your input device, for that execute next command
Code:
# alsa_amixer cget numid=3
try numid value from 1 till you will see your input device or message that device doesn't exist
for example my respond:
Code:
numid=3,iface=MIXER,name='Input Volume'
; type=INTEGER,access=rw------,values=2,min=0,max=512,step=0
; values=488,488
- if values is less than max (in example 488<512) then you can continue, type next in console
Code:
# alsa_amixer cset numid=3 512,512
Code:
numid=3,iface=MIXER,name='Input Volume'
; type=INTEGER,access=rw------,values=2,min=0,max=512,step=0
; values=512,512
Settings will be applied till next reboot, after reboot you will execute it by hands again (I found no way to start it automatically at system boot).
So before reboot you can perform:
Code:
# alsa_ctl store
After reboot you can restore:
Code:
# alsa_ctl restore
2. Another way through audio device registers. This way is different for each audio device and should performed accordingly to chip documentation. For example for chip WM8987 (which is used in Superpad).
Microphone boost configuration are stored in the 5,4 bits of 0x20 register (left channel, 0x21 right channel in my device unusable). Configuration of input lines stored in 7,6 bits the same register.
Code:
$ su
- to see current settings perform next
Code:
# cat /proc/driver/audregs
in response you will see current settings;
- from chip datasheet:
Code:
5:4 bit | boost | hex
00 | off | c0
01 | 13dB | d
10 | 20dB | e0
11 | 29dB | f0
- write this registers into devices, for example for 29dB (mix will be little bit noisy so you can try 20dB) boost:
Code:
# echo 0x20 0xf0 > /proc/driver/audregs
- for autostart create XXmicfix (where XX - any unique number) file inside /etc/init.d with next text inside:
Code:
#!/system/bin/sh
echo 0x20 0xf0 > /proc/driver/audregs
Hope this will be helpful,
That's all.
This is a list of all threads avaiable to our phone, using for ROM developer too...
i decided to post in general, becouse this is not developer threads, developer threads are done from developers and i'm a human no developer.
Adrenaline Shot v14 Universal What do these tweaks do?
the first improve is under /system/bin, replace 2 bin with leaked from ICS 4.0 , with GREAT EPIC improvement , 2 bins 're app_process and system_server.
app_process executes, and executes a runtime environment for a dalvik class
The system server is the core of the Android system and as described in the boot sequence post it is started as soon as Dalvik is initialized and running.
like all tweaks , this will add some /system/etc/init.d script , if kernel supports of curse
( for everyone using Gentoo, know init.d too )
the first one is 00remount
Code:
#!/system/bin/sh
#Partition mounts by Dsexton702
mount -o remount,noatime,nobh,nodiratime,nodelalloc,noauto_da_alloc,barrier=0 /system /system
mount -o remount,noatime,nobh,nodiratime,nodelalloc,noauto_da_alloc,barrier=0 /cache /cache
mount -o remount,noatime,nodiratime,delalloc,noauto_da_alloc,barrier=0 /data /data
This script will (re) mount the EXT4 partitions with some "tweaks", like noatime, nodiratime,delalloc and soso.. , speed increased in R/W
the second is 01kerneltweak
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_GENTLE_FAIR_SLEEPERS > /sys/kernel/debug/sched_features
unmount /sys/kernel/debug
using NO_GENTLE_FAIR_SLEEPERS as schedule features, nothing to hard
the third 02journaling
provide to delete cache if its too big
the 4th is 03sysctl
Code:
#!/system/bin/sh
sysctl -p
This is simply call to sysctl ( parameters settings under linux kernel ), its under kernel tweak
the 5th is 04sysctltweaks
this will set a lot of utils things about kernel and its driver ( like governor ) , if people using ondemand it will set ondemand/up_threshold to 65 ( more responsive , but increase battery drain ) and ondemand/sampling_rate to 30000 ^^
05sdcardspeedfix
fixing READ_AHEAD_KB , suggest it will increase sdcard speed ( not too much )
06zipalign
provide to zipalign all /data/app/*.apk files, anything know to apk files are zip archive contains a lot of things, zipalign optimize this archive , major info at developer.android.com/guide/developing/tools/zipalign.html
07vacuum
this provide to "VACUUM" all *.db ( see SMS's DB, etc ... ) to rebuild all *.db better, increase performance too!
08ramscript
i never will use this, this is not designed for our phone IMHO it can be replace with superchanger ( see after )
/system/lib/libsqlite*
will replace sqlite's lib for better performance, sqlite has sync and async method, this will disable sync , theorically it will double the performance in I/O
/system/xbin
it simply provide a sqlite3 bin and zipalign bin, nothing tweaks
Click to expand...
Click to collapse
Thunderbolt tweaks ( this is not avaiable, i upload some script i've download a time ago )/system/etc/init.d
s78enable_touchscreen_1
Code:
#!/system/bin/sh
#Touchscreen
#Configure touchscreen sensitivity
#Sensitive(Chainfire)
echo 7035 > /sys/class/touch/switch/set_touchscreen;
echo 8002 > /sys/class/touch/switch/set_touchscreen;
echo 11000 > /sys/class/touch/switch/set_touchscreen;
echo 13060 > /sys/class/touch/switch/set_touchscreen;
echo 14005 > /sys/class/touch/switch/set_touchscreen;
this is IMHO the best script i've ever seen , this will increase sensitivity of touchscreen
07sqlite_optimize
this will vacuum and re-index all db, better than Adrenaline's 07vacuum IMHO
S70darky_zipalign
Another zipalign script, useless
*bolt_siray*
this is not developer for our phone, this will working only with adeguate kernel ( we haven't )
S98CFS
it will provide a lot of tweaks using sysctl and kernel proc/ interface
S98system_tweaks
this is a lot of script unify in one script
i edit this to be "better" with our phone, i delete re-mount runtime , adrenaline's 00remount do it better
and modify this part:
Code:
# ==============================================================
# smartassV2
# ==============================================================
if [ -e /sys/devices/system/cpu/cpufreq/smartass/awake_ideal_freq ]; then
echo "800000" > /sys/devices/system/cpu/cpufreq/smartass/awake_ideal_freq;
if [ "`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq`" -eq 300000 ]; then
echo "300000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_ideal_freq;
else
echo "300000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_ideal_freq;
fi;
echo "800000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_wakeup_freq;

echo "0" > /sys/devices/system/cpu/cpufreq/smartass/ramp_up_step;
fi;
to have a correctly step for our processor
"after applied this , my phone morth into blonde, blue eyes galaxy Supersayan [cit.]
THIS IS THE ONLY MEMORY Manager, this provide a better ram manager by android, anyone know that Random Access Memory contains a kernel and all APP run, kernel are loaded in lowest address possible , and all app are loaded when open, android usually doesn't close this, for better speed when you re-open its, but if you have small RAM ( 512 MB too ) this will cause a lot of problem , superchange fix it!
i suggest to use 512HP Balanced ( or Performance ) with Bulletproof launcher + OOM FIX, Nullify lag work too
HOW INCLUDE THIS INTO MY ROM?
Poseidons ROM include this by ****ty init.d script, i suggest to delete and re-apply
if you are not ROM Developer is simple, download latest avaiable by link i provide at top and with ROOT-enabled ( check su ) and Script Manager ( or terminal emulator -> # su -> sh script_location ) follow the scripts guide, remember, using this can cause ( 0.01% ) bootloops, i suggest to use local.prop and init.rc integration
if you are a ROM Developer is more complicated than simple user, for stick you can use:
init.d script ( like poseidons )
local.prop and init.local.rc ( suggest ) under /data
build.prop
init.d script ( i do not see this, for me is the worst way to get it )
init.local.rc:
create a /data/init.local.rc contains

01loopy
this will make phone more smoothness by renice ( change priority ) the main process will run
i suggest to set your launcher process here like:
Code:
### Launcher apps ###
renice -19 `pidof com.sec.android.app.twlauncher` # TouchWiz Launcher
renice -19 `pidof org.adwfreak.launcher` # ADW Launcher Ex
renice -19 `pidof org.zeam.core` # Zeam launcher
renice -19 `pidof info.tikusoft.launcher7`# Launcher 7

This will provide a complete collection of tweaks avaiable, i hate this becouse, a lot of tweaks here are not implemented correctly , like:

zOOM zOOM :
Code:
echo "2560,4096,5632,10240,11776,14848" > /sys/module/lowmemorykiller/parameters/minfree
This is the same things that do superchanger, but this will be wrost for our phone IMHO
Code:
echo "20" > /proc/sys/vm/swappiness
the right value ( in my cases ) is 0, i haven't swap of anyway we dont have to have a swap!
Zipalign Runtime, it will just implemented by a lot of script, this is also the wrost IMHO zip align script i've never seen
Code:
for k in $(busybox mount | grep relatime | cut -d " " -f3) ; do
sync;
busybox mount -o remount,noatime $k;
done;
this will break 00remount script
Code:
for i in /sys/block/*/queue/scheduler ; do
echo "noop" > $i;
done;
if kernel support i suggest deadline
Code:
# Tweak kernel VM management
echo 0 > /proc/sys/vm/swappiness
echo 10 > /proc/sys/vm/dirty_ratio
echo 4096 > /proc/sys/vm/min_free_kbytes
??? WHAT? again?
Code:
echo "interactive" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "cfq" > /sys/block/mmcblk0/queue/scheduler
see upper
Code:
echo "deadline" > /sys/block/mmcblk0/queue/scheduler
What? another change?
this is good:

#End Cranium Tweaks
Conclusion: 95allinone is simply a addiction of all tweaks avaiable in one script without any review and improves for our phone ( in this case, this work ), this will only increase the boot time and break others tweaks installed ( some )
99V6_Superchanger
DO NOT USE THIS, THIS IS EPIC FAIL INIT.D SCRIPT!
Code:
mount -o remount,rw /system
mount -o remount,rw /dev/block/mtdblock3 /system

*facepalm*
in my terminal:
Code:
# su
# ls -la /dev/block/mtd*
ls: /dev/block/mtd*: No such file or directory
anyway this is not init.d script, this is v6 script , this is not compatible with init.d ,

WHICH GOVERNOR DO U USE?( ref: Simba501 )
SEE THIS
Anyway i suggest:
- Smartassv2 if you want performance over less battery
- InteractiveX if you want battery over less performance
CAN ANY KERNEL DEVELOPER INCLUDE LULZACTIVE CPUFREQ-DRIVER IN OUR KERNELS? ITS THE PERFECT GOVERNOR , EITHER FOR BATTERY AND PERFORMANCE
EGL TWEAK!Android header said:

# D: display (0: default)
# I: implementation (0: software, 1: hardware)

in the stock ROM the egl.cfg is:
Code:
0 0 android
0 1 POWERVR_SGX530_125
what's meaning?
simply using cpu ( with gpu too ) to render all apps and system
if you modify to:
Code:
0 1 POWERVR_SGX530_125
it will use overall GPU render only, more fast and imho better Battery life because, CPU in our cases with overclock consume more than GPU

Battery life is influence by:
Running Apps
Governors do you use
Memory Manager ( #1 addicted )
If you set /etc/init.d script to set conservative governor and implemented v6 without any stupid app like facebook or bloatware samsung, and your battery seems infinite
in the past i used SCH Rom , its used only v6 and most important tweaks , without any stupid bloatware, battery seems very infinite ^^ like 2% in 5 hours under 2G network
Ok, sorry for my noob question but I am learning a lot of things this days.. where can I find a tutorial about how to set a governor or a frecuency by default in my kernel? Thank u very much

I'm noob too
for frequency are too kernel releated to be generalized,
or if you using XDA_Bam kernel
39frequency
Code:
#!/system/bin/sh
echo "300" > /sys/power/overclock_opp1
echo "600" > /sys/power/overclock_opp2
echo "800" > /sys/power/overclock_opp3
echo "1000" > /sys/power/overclock_opp4
anyway you can create init.d script like
40governorbattery
with:
Code:
#!/system/bin/sh
echo "conservative" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
and see if it stick ^^
Hi.
Are there codes that can remove or dissable the TouchUI aka TouchWiz interface on the i9003 and just use the android deffult launcher?
Another thing something that will easy-up my ram usage and allow more usable ram?
If so how do i implement them?
I just want to add a cool sound and audio tweaks using MagaBassBeats_Mod
First download the MagaBassBeats_Mod_9003.zip file from the xda forum.
Now copy it to the sdcard.
Reboot to the recovery mode.
Now select install from zip file and chose internal sdcard.
Search for the zip file, hit power button, and chose yes.
That's it now you can enjoy a great sound quality.
details from here
