[Q] voltage - Galaxy Tab 2 Q&A, Help & Troubleshooting

Im using CM 10.1 for GT-P3100.. With " blackhawk_kernel 0.3 landscape " which gave the ability to control voltage
I want to know the minimum voltage i can do.. With no problems in the tab !?
Thanks you

[MOD] enable 10 point multitouch SCREENSHOTS ADDED!

hey guys!
there have been a lot of requests for this mod so i decided to post a tut on how enable it! UPTO 10 POINTS TOUCH IS ONLY SUPPORTED BY CM FIRMWARES! NOT ON SAMSUNG FIRMWARES!
our touch screen sensor is the Atmel maXTouch mXT224 which by default can track upto 10 touch points with pressure sensing. it is the same sensor used in the galaxy s and galaxy tab. as we know samsung isnt the smartest and decide to keep the limit to 3 on our devices. this basicaly tells it to track all 10 touch points. in the kernel sources-
in the file: Kernel/drivers/input/touchscreen/qt602240.h (tks dharamg3 for the correction )
change:
Code:
5277: //#define MAX_NUM_FINGER 10 // Maximum possible fingering
5278: #define MAX_USING_FINGER_NUM 5
to
Code:
#define MAX_USING_FINGER_NUM 10
this will enable 10 point touch at kernel level.
at firmware level in the sources-
Code:
froyo/services/java/com/android/server/InputDevice.java
Set max_pointers to 10.
note-
in cm firmwares 10 is enabled by default so no need to change the firmware sources. samsung firmwares limit it to 5. therefore even if kernel sources are changed, it will track 5 and ignore the rest.
this poses no harm to phone.... it was always capable of doing it.
this mod is based on the galaxy s mod-
http://forum.xda-developers.com/showthread.php?t=891030
one last thing- dont tell me its useless on such a small screen. (i know )
but u never know when it could come in handy. wont affect ur phone in any other way and no harm in leaving it enabled.
hit thanks if i helped!
UPDATE-
SCREENSHOTS ADDED- u dont know how hard it is to get all 10 fingers in and then take screenshots
also when going over 7 touch points its less glitchy when u keep ur fingers further from each other.....
Finally people will stop pestering rom developers to include 10 point multitouch

where can i find the drivers folder in root explorer ??
and im using cm7 a6.1 2.3.5 it would do the job right ?

u cannot directly use this mod. u will need to modify the kernel sources and then compile it. this tut is mostly for devs who would like to impliment this to thier kernel.

had already tried 10 with samsung firmware, but didnt work out...so had restricted to 5 when i did it in g3mod kernel...

You can use a script, search for it and you'll find it, although for this mod you'll need the source, but you'll also need to decompile the kernel for the initramfs

but the only thing is on samsung firmwares only 5 fingers will work and on cm 6.2

if i get cm 6.2 sources then i can compile a kernel which will work with all cm6 feature that work on our phone.

what does that mean(sio, deadline etc..) .......... also i'm on ardat's kernal 1.7 ........ oc it to 1.2ghz......
is SetCpu application makes our SGR hotter ?? i mean will the temperature of the phone will be increased ???
If you overclock using any application or set a high cpu clock speed for constant use like min max 1200mhz then yes, you will slowly cook your phone.. But if you set the values properly.. Then you'll get a hell lot more battery life..

Studied & Picked up few sources from git's ... And just figured it out that every clock speed has been assigned a specific voltage so out of trial and error method i found tat the more i undervolt the system seems to lag .... So when i got a stable system i compiled the build.... U can also say that the undervolt is still in beta stage cause u never know if the scaling set is correct till u experience bugs but...so far so good i've been gettin a stable result :fingers-crossed:
But I read that scaling differs from device to device?
Just like oc, some devices can handle more, some less...
System lag is bad news though...
Will make uv pointless, and also the time I would have spent improving the way...
What about uv+oc?
"By the power vested in me, I now pronounce you, Man and Knife"
yup scalin of frequencies differ from device to device nd that is y i've used sources from tj_style's git .... i would still hav to concentrate on OC + UV together cause it needs lots of testin .....

well, im so proud to see another lebanese developer over here
im gonna flash it and give it a try
bas habibi bil post u said ( n7000 ) l galaxy note 2 is ( N7100 ) one more thing bi3ti2id ino l original charger gives only 1100 mAh not 1700 so correct me if im wrong
and if it was as i said just 1100, set the charging maximum to 1200 instead of 1700, otherwise a lot of phones will be dead when left on charging all night long
and try to make it cwm flashable, its better and never increase the counter in download mode
phone never boot up just stuck on black screen after the note 2 sign, are u sure it is for note 2 ?? or for note 1 ?

Sent from my GT-N7100 using xda app-developers app
Thank u dude for trying my kernel. Actually the only thing that may coz a little above normal power consumption is that the CPU is clocked on 2 Ghz as the maximum scaling frequency. If you set the max freq of the cpu back to 1600 Mhz using any tool like SetCPU you will have less then normal drain and power consumption bcoz of the extensive undervolting applied to the CPU, GPU and Midas chips. Also the fact that its zRam enabled make it conserve power bcoz RAM usage will give less power consumption than the MMC in this case.

Sorry guys as I don't have much time to spend on this project. I'm working on it in my spare time. Stock (Touchwiz) have some issue right now as actually its not my priority right now. Actually I'm working on Call Recording feature for the AOSP.

Tab 4 10.1 lollipop screenshots (In Depth please)

Can every tab 4 10.1 user put lollipop screenshots and experiences please
yeah id like to see it as well nice thread op
tab4, 5.0.2
I like the update, its faster and i get more out of the battery.
yesterday the first day on lollipop out of a full day social media,multi window 40% on the time and chromecasting i got 6:30 screen on time. i have had no problems so far, on the first boot i had a few times that apps stopt working for no reason, after rebooting there were no more troubles. So far i did not play games, today im gone play all my games and see how the battery&cpu handels it, on 4.4 i had the problem that my tab4 got hot(cpu) and started lagging.
so far so good, the tab works faster and its a joy to works with, no more lagg like 4.4 for me its a difference and the screen reacts better/faster.
Im going to add a pic from my score on antutu.
I'd like to see a video from lollipop on tab 4 10.1.

I dont remember which XDA thread had it but im 100% sure that it will come in few weeks if it wont get delayed.
This is screeny of my newly updated (today) 5.0.2 tab 4 10.1 - wondering if anyone can tell me why or what that white "my files" icon in the lower left is ? I can't remove it though and it's ticking me off -
here's another screeny - and I actually used the palm swipe gesture to take the shot - so far one of my favorite additions to lollipop -
edit : sorry for the crappy quality - how do I fix that ?

Okay , fun thread ! :good:
I absolutely LOVE the new TW LP [sm-t530nu]
I already got my kernel sorted, debloated, rooted, and baptised by coffee ! xD
Seriously though this rom runs nicely. I'm still hunting down battery/power saving commits rather than apps.
The browser layout is alot more clumsy-thumbs friendly :good:
Audio still needs an available/find-able toggle for SW encode/decode so i use MXPlayer.

hi for me yes, for everyone else no, BUT, this is my standing corrected source for the sm-t530nu
https://github.com/moonbutt74/kernel_samsung_SM-T530_EUR_LL/tree/dirty-bitz
compile with gcc.4.8 , uber or linaro or vanilla, shouldn't matter too much
edit the go script for CROSS_COMPILE= and STRIP= to your correct toolchain path
to compile my current defconfig
or edit reset script for the same for a "stock" compile, the default defconfig and variant defconfig may need to be edited
compile will output to build directory
from there use AIK to unpack a copy of the stock boot.img and replace kernel binary and dt.img then repack
don't forget modules!
you can re-purpose one of my kernel packages for packaging you own build.
