[Nexus 7 (2013) General] Hnk1:
Hello

I had been using TRAIL and ERROR method since a year now and I can tell you most of the time it worked flawlessly and improved the usage of the tablet by atleast 90%. To conduct this extensive sort of experiments, I always had "show touches" turned on in developers option in settings.

Little history of problems I encountered while on STOCK TOUCH SOFTWARE :

Got it on 3rd August 2013 when it was out NO ISSUES

Update came for fixing random restart/multitouch SCREEN USE TO HANG, A KEY USE TO STUCK

On 4.3 Key Jumping/ ghost touches

on 4.4.0 to 4.4.2 No issues

4.4.3 Little key jumping/ ghost touches

HOW I FLASHED EVERY TIME

USED as STATED in guide, however,

If you are on 4.4 (any version), after flashing, you would be stuck on bouncing balls. Ignore it and wait for about 2 minutes.

Type adb reboot or manually REBOOT ; this time you would be booted to your homescreen. Wait and check! It might still be buggy! Wait a minute more and RESTART AGAIN!

When the home screen comes again, just check and see if the version you flashed works for you!

Another thing I noticed is that it takes around a day or two for touches to settle down, like flashing one over another wouldnot work for you at all in few span of hours.

Flash a specific one and wait for about two days before flashing other unless it gets unusable.

Repeat in case it doesnot!

MY EXPERIENCE

ON 4.4.3

Flashing this solved my problem on 4.4.3

I used t10 version.

4.4.4

Update 4.4.4 : Boot takes a long time. I think maybe I face battery drain. I left my nexus over 30% and in the morning it was off and when i switched it on, it was only 4 % (I connected the charger first and then tried to turn it on)

The touch issues came back but restart solved it.

T11 also works for me with no real difference. One thing i am noticing is the amount of restart time though, it takes a long time. I am using elementalX kernel for Stock!

I guess if it doesnot work for me as well as it should, I would go back to STOCK 4.4.2 / Custom 4.4.3.

Later I realised, a clean flash of Nexus Image 4.4.4 reduced the boot time.

UPDATE 2 :

Unlocking bootlooped my nexus. Stuck on Google Screen! back to stock touch drivers

update 3 :

reverted back to stock 4.4.3 with no issues . Seems like rooting+custom kernel+ recovery might be to blame.

Update 4: rooted + kernel elementals + twrp 2.7.1.1

Jumping screen returns if playing a game for a long time/or gets heated !

Update 5 :

At times the screen would again go CRAZY, so i decided to intall t-20 and see what happens! Works fine now but lets see.

This time, I was on CM 11 m8 4.4.4, booted into bootloader and then flashed the zip via fastboot. Then I just waited for about 2 minutes and nothing happened except for green lines followed by addition of pink ones. I used adb to reboot and that's it.

The problem diminished by 90. Ghost touches were only seen on right side but didn't affect screen much. Reboot time is very quick as before now

Update 6 :

Flashed t30, the sensitivity has considerably decreased on right side and some very gentle touches aren't registered on top right end. But dragging and tapping a bit firmly works. I have also noticed key sticking on t30 which is very brief. This means, if you touch somewhere else, it goes away immediately. However, the major issue here is some touch not being registered

I found screen going a bit crazy like t10, however much better than t10.

Update 7 : Flashed test built 25.

It worked fine on stock and L preview version! But now on CM 11 4.4.4 M10, I am again having some issues. I flashed 4.4.4 stock and then flashed CM 11.

On test 25, at times I had to press the key twice due to reduced sensitivity. However, I didnot have any ghost touch or anything like that!

I suppose this calls for another test !

Lollipop (5/5.01/Preview Builds all have been the same story for me, maybe I should check STOCK)

Currently I am still on test25 with 5.01 Lollipop and ElementalX kernel (3.03) and apart from at times the touches arenot registered when I open my magnetic case (which is solved by using the button or cleaning the screen) I hardly have ghost touches (once or twice in two months), I think I am happy enough and wait until I have more problems that would force me to try something new.

went back on stock. It was fine in the beginning but now it is getting worse and keep hanging plus random touches. BAD BAD BAD

Trying t16.

VIEWS OF ANOTHER USER [MENTION=5367562]lomonic[/MENTION]

After many days of testing various patches, I've concluded on TS-16. Below are my test summary if it helps anyone.

Problems I faced with

- stucked touches, rather frequent

- ghost touches, very seldom. Only noticeable in very touch intensive games.

- missed touches, seems to happen a lot with typing.

- all the above happened regardless hand held or on a non conducting surface. Happens a lot more on a non conducting surface. A reboot usually fixes things for a while before it starts again.

TS10

- Works well, but has very seldom 5sec freezes that recoveries and goes wonky at bottom of screen after extended uses.

- Fixes stucked touches.

- No noticeable ghost touches or missed touches.

TS20

- Works and feels better both single n multi touch compared to TS10.

- BUT has unexplainable random system freezes that requires hard reset. Happens very occasionally and only in touch intensive programs.

- Fixes stucked touches, ghost and most missed touches.

TS25 and TS30

- Fixes stucked touches.

- Ghost touches becomes more frequent near bottom of screen.

- Touch feels a lil wonky too.

TS18

- Fixes stucked touches.

- Ghost touches and missed touches are unnoticeable.

- Multi touch in Google maps is less responsive.

- Random freezes also encountered as per TS20

TS14

- Fixes stucked touches

- Ghost touches and missed touches are unnoticeable.

- good responsiveness in google maps.

- typing feels a little inaccurate.

TS8 TS6 AND TS9

- all feels very sensitive.

- feels random wonkyness

- fixes stucked touches

- no noticeable Ghost touches and missed touches.

- typing seems overly sensitive and results in many errors.

- random wonkyness happens after extended use and short self recovered freezes.

TS16 - my favourite

- Fixes stucked touches

- no noticeable ghost touches or missed touches

- no random freezes experienced, not even the self recoverable freezes.

- good balance of sensitivity and accuracy.

- good multi touch responses in Google maps and Google earth.

- no problems in most instances when using on a flat surface.

Just a note to everyone. I have given at least 3-4 reboots after each update, and run them for at least 24 hours playing touch sensitive and intensive games like Turbo racing using multitouch to slide and more around.

Hope this helps. Thank you sfhub for filling the gaps where Google and Asus have not. Great patches for everyone to suit your usage patterns.
