Was using ts10 until 4.4 was released then applied the unlock and flashed 4.4 factory image (removing '-w' from the batch file so it doesn't wipe data). It's been perfect since then even with the 4.4.2 OTA. Even on an ungrounded surface, without touching it with the other hand and holding down one or two fingers on Google Maps, Waze, etc. there's no erratic screen movement like it used to do with earlier OS versions and even the original Nexus 7 2012.

If you guys are still having issues I'd suggest trying that.
[Nexus 7 (2013) General] sam298:
Thanks. TS14 works fine as described. Single touch (keyboard) works without dead spots both grounded and not grounded. Thats what i need the most. Has the ghost multitouch when double touch is in a line.

Still few dead spots but very tiny. Might be an issue only if you try to move cursor to edit text. I will stay with ts14 for now. Thanks OP

Hi sfhub, my nfc doesn't work so i'll be sending it back today.

I previously flashed your touchfix back when i was on JSS, now I'm on KRT and was just wondering, will i need to flash the restore file for the touchfix before sending back, or can i simply relock the bootloader and be done with it?

Thank you!

Does all the n7 having touchscreen issue currently?

So far I have not recognize any issue really happy with that tablet so much.

But as well this is my first nexus device as well as tablet device so I would like know how can I check if I have that issue you are talking about would appreciate any advice you can possible give me
[Nexus 7 (2013) General] dehsA:
Get one of the multi-touch test apps. I personally use Multitouch Test by Easy Labs.

For me I've always had problems with three fingers in a right angled triangle formation where the finger at the right angle will lose its touch. With four fingers in a rectangular formation, all four fingers would nearly always not be detected.

Of course, your Nexus 7 should be placed on a flat surface during testing.
[Nexus 7 (2013) General] Matrix_19:
When I want to test not grounded... The best way is to test the tablet on the pillow. Sometimes on a flat surface you don't get the same result all the time.
[Nexus 7 (2013) General] nomikSqash:
Just check it with 4 app to be absolutely sure but have not seen any issues. The only thing I notice while trying 3 finger and 4 as you said that since I don't have on screen protector it's 'clean' screen, I notice a bit lags but it's only because my fingers were a bit watered after gym, beside that have not seen issue with 3 fingers at the right top or 4 basically tried all different kind but I don't put more then 3 fingers on screen nevertheless maybe I am not doing something right but the screen seems to be fine but I want to be sure so to use these rar's from OP or not any other way?:sly:

Have you tried one of sfhubs ts files?

>^.^< Sent From Meow nexus5
[Nexus 7 (2013) General] dehsA:
Yeah, I tried them all. None made it significantly better but I did use ts09 for a while but it became worse after about a week or so. I recently flashed factory image and never really bothered to flash one of the ts's again.
[Nexus 7 (2013) General] mj0528:
yea,i've tried about 4 or 5 and it's probably time to get a refund. I'm wondering if I should go to stock and upgrade to kitkat since I started at 4.3 and root and went custom right away
[Nexus 7 (2013) General] Sensamic:
Read my post above yours where I explain my way of testing this.

When I see that I get scared to buy another one! Don't know what to do. There's really no other tablet I like, but these problems are just amazing.
[Nexus 7 (2013) General] nomikSqash:
To tell the truth I was scared a lot but then I checked mine and I have a bit less in more details when I open Google maps Google earth and try to pinch in everting fine but when only my fingers come together screen go s bit crazy.

Do not really want to try any zip etc so far the screen quality is amazing I mean I am watching serial's w/o problems reading books and a bit of gaming as well and browsing of course for all that the tablet really suit all my needs there is that bug but there is no much I can do except trying to flash something that might be in result of boot loop or in future update issue.

There is an issue I know but I can do my daily basic things w/o noticing it.
[Nexus 7 (2013) General] dkryder:
When I first got n7 3 months ago I had an issue with touches not registering about 30% of the time. The issue slowly got worse to the point that about 70% of my touches were not working. I started to think about getting an accidental damage RMA for the unit. However, the 4.4.2 update resolved the issue to the point that now only about 5% of the touches do not register. I can live with that. About the only lingering downside to my problem is that I do not wish to experiment as far as installing kernels and/or ROM s

I do not want to mess the thing up at all. If it remains stable and working well for the next couple weeks I plan to begin seeing what other kernels/ROM s are like.
[Nexus 7 (2013) General] Sensamic:
So the touchscreen problem can actually go worse with time?

That's really scary.

You could buy one with many little problems but a few months later it becomes worse and almost unusable.
[Nexus 7 (2013) General] doubleho:
if u have a screen protector, take it off, fixed mine with that
[Nexus 7 (2013) General] dkryder:
Mine did. At first I was thinking that ambient temperatures played a role since it was getting colder with winter coming on. I even started warming the device between uses when I could. I had it sitting next to a small space heater to keep it warm, although the temp of the room was 72-76 degrees F. That did "seem" to help but not drastically. (Might have been placebo effect) anyway, I was frustrated as heck and ready to bail. I wanted for it to start working so much that I did a sideload which went against a rule I had to not mess with any attempts to alter it myself. I was surprised as heck when it started to work and sorta expected it to screw up soon, but it hasn't. Knock on wood it's been 10 days since the update.
[Nexus 7 (2013) General] hakcenter:
Thanks sfhub,

I am a recent owner of a Nexus 7, was having a ton of fun with it the first few weeks then KitKat came out... and I noticed that the touchscreen just started becoming completely unresponsive when I would use it on flat surfaces.

Holding 2 hands was no prob... so I started looking and honestly it is pretty sad its come to a thread like this to try to alleviate peoples issues.

In any event, I put ts10 on my unit, currently on cm11 nightlies (12/17) to be exact, and I can use it again like normal. I got pretty scared at it freezing just after the adb command, and it took over a minute to unfreeze but it ended up booting and worked awesome from the first boot... rebooted it anyways.

Just wanted to post a big :good::good: for ya. Now I can go back to my dash install.

[MENTION=1299673]sfhub[/MENTION], since updating to 4.4.2, I seem to have more ghost touches, did the touch screen driver change between 4.4 and 4.4.2?
[Nexus 7 (2013) General] nomikSqash:
So far I made a small research basically all the android devices have a small issue with the multi touch or screen in general it can be a small issue that you will never notice on your phone or tablet or a big one.

For example ppl from Samsung note 2014 having also big issue of response of the device. It might be because of the pixels that are located on the screen its simply too much. But you can say that iPad or iPhone never having this issue what is logical due to the operating system that is installed there. But so far if you compare galaxy s3 and iPhone dead spots and response of the screen is much higher at galaxy s3 read this research few weeks ago.

All ppl having issue with the n7 devices some do not want to see it some were not lucky to have it the way more then other. So far I am also happy user of that issue and to tell the truth I don't really care, I mean I really do but as far as I can type w/o lags and do all my other daily that things I am really happy n7 user :)

P.S sorry for the of topic but was doing a bit of research and thought to share it with you guys
[Nexus 7 (2013) General] xR3BorNx:
Guys. One question, do you think i can use this files for my nexus 7 2012? Having phantom touches and unresponsive screen. Turning off the screen able to fix that. I think i got it since i update to jelly bean and now on kitkat. :/ i changed my kernel right now to see if that helps.
[Nexus 7 (2013) General] ghost02:
Hi guys, been running quite nicely on ts11 using a 4.3 rom, if I want to experience the 4.4.2 improvements after running ts-unlock to I have to install the original google update or will custom roms and kernels such as elemental work after ts unlock?
[Nexus 7 (2013) General] mj0528:
09 seemed to be the best for me but it really stinks that this has to be this way. I can't really consider anything larger than the 7 inch size moving forward and the kindle just doesn't do it for me :)

I give much thanks to the devs that make such a POS a great tool/toy!

I'd have to respectfully disagree with you. So if I understood u right u said that all Android devices have some sort of touchscreen issue because of the OS of Android. Also that iOS doesn't have screen issues because its OS is iOS. I've had many many android devices and they don't all have issues its the touchscreen itself which has many manufacturers which is the cause of the vast majority if touchscreens issues. The fact that so many people have a wide variety of issues and strength of the issue proves this. We are all running the same stock setup on the android side as far as how the touchscreen is calibrated. Sfhubs fix changes all vary in strength because each individual touchscreen has varying strengths of issues not the stock OS. So its the touchscreen itself that is borked in the n7s issues. The OS side or software can cause issues but Android itself as an OS isn't the issue and its not the issue here. This is why everytime Google changes something it doesn't fix it for everyone in fact it makes it worse for some. Now that's just what I think it doesn't mean its completely correct cause I'm far from an expert when it comes to this. I'd like to hear sfhub and some of these other really smart users views on this though

BTW Google iOS touchscreen issues ;)

[Nexus 7 (2013) General] xR3BorNx:
I thought so. :/ but after changing the stock kernel to a custom one. Screen issues seems to disappeared now. Gonna use this kernel from now on. :) but thanks for the reply for a minute there i thought i should give this one a try. :)
[Nexus 7 (2013) General] mj0528:
So 09 didn't turn out to be the one. Starting to think I need to dismantle this thing to see wtf. Anyone for any suggestions. This is driving me nuts. I don't want an 8 inch tab but it's looking like it more and more
[Nexus 7 (2013) General] dehsA:
I'm already getting myself a GPE LG G Pad in a month's time and selling my Nexus 7. No regrets paying significantly more in exchange for a fully functional touchscreen.
[Nexus 7 (2013) General] nomikSqash:
That's absolutely right but you was not reading carefully since as I wrote the nature of iOS and android is absolutely different structure and since the iOS is really close os compare to android it has less bugs but even beside that I wrote that even 2 year old Samsung Galaxy s3 have better multi touch, response in the different zones of flagship then iphone. Nevertheless Google any kind of device with any kind of problem and you will get tones of article, its like screen on old transformer infinity .

You might be right and software isn't the issue it's the hardware I fear not would like 1 day to have fix for screen w/o any issue :sly:
[Nexus 7 (2013) General] dehsA:
Which?
[Nexus 7 (2013) General] Richieboy67:
Does anyone have issues when using the screen normally or are these issues only noticed when testing?

I have tried to find these issues when using normally. The only issue I find is when putting the device on a pillow touches are not always noticed. I never really use my device that way nutrient and only did it to test. Other than that I cannot find any touch screen issues.

I also play ass - fault 8, real racing, etc and no problem.
[Nexus 7 (2013) General] nomikSqash:
Yes I would like to know as well using clean room and Ex. Kernel

Having issue with (tested only on these might be more) screen going crazy when fingers touching each other very noticeable in app like Google earth and Google map have tested on my s4 no issue at all.
[Nexus 7 (2013) General] mj0528:
i am almost right behind you. I just bought the 7 a week ago from Best Buy so it may be returning home tomorrow :)
[Nexus 7 (2013) General] player911:
I've heard real good things aabout the LG GPad. I bought my N7 day 1 and way past the return period.

The N7 drives me crazy. KitKat fixed my touchscreen issues for the most part but I still get stuck touches in games. I keep playing Terraria and my character will just randomly run into a lava pit, killing me and losing money. Doesn't happen often, but often maybe once an hour. Enough to be annoying.

anyone?
[Nexus 7 (2013) General] DowntownJeffBrown:
Yes these ts files should help you. Start with the main 3 and if none of those completely fix the issues then pick the one that's closest and use the experimental ones close to it to fine tune.

Currently testing ts10 package, eventually wanted to give a try to it.

So, reboot the android 3 times, seems like it has to do something with that

Rom: CleanRom 2.6 (4.4.2)

Kernel. Ele.

Basically i never had any issue with the tablet b4 i tried the multitouch app, to say so i mean that in my daily use of the tablet i did not experience any discomfort with it.

b4 the package ts10 issues were:

Google Maps/Google earth screen goes crazy when your fingers touch each other (pinch in)

In Multiotuch app: The dots goes crazy as well when fingers touches

When u make 2 touch, in the same line they like jumping from it, seems it is not possible to get 2 touch in the same line in that device

Having 9 touches on screen brings up no problem

2 touch on right and left border of screen makes them change the dots :confused:

After the package (still will use it for a couple of days until change to ts20) none of these issues were resolved, (seems like will never be -_-) but the good point is that i felt kind of more screen responsiveness, we all know that kitkat is by any mean not slow, but that package brought more responses, did not resolved the issue but nevertheless something.

cheerz
[Nexus 7 (2013) General] marsaltito:
i just tested ts10 + cm-11-20131220-NIGHTLY-flo.zip nexus 7(2013) and its like that helps with multitouch just stil ghoust touch sometimes (50% less), for me is not big deal just when play games and games is not so important .

i will try rest from package and report my opinion abouti it .

Note to people who might read the OP too fast:

fastboot boot *****.img != fastboot flash boot *****.img

had to spend 2 hours fixing my N7 and redoing that before I realized that little mistake.

Thanks for the help OP - it's really helping. Once I actually, ya know... read the whole post.

Almost perfect here as well with 14
[Nexus 7 (2013) General] marsaltito:
i just tryed some of combi :

*two fingers same hand respons sensitive ( weary light touch recognised ) ,react on finger even if not touching screen (1- 0.5 mm over screen) !

*two fingers two hands respons much better (not so sensitive)!

just thinking if that problem have something to do with magnet or static electricity ?

tested with multitouch test app boot-ts10-lock.img on one and boot-ts20-lock.img on second N7 2013 same result

*EDIT: when taked out of of trifold with magnet lock then behavior is little improved and one of N7 have screen protector is much worse then other
[Nexus 7 (2013) General] Aztriltus:
Oh my god. I bookmarked this thread but was lazy to do it while I continue to get more and more pissed off at touch issues especially when my N7 lays flat on the table. Almost 50% of the touches were not recognised! So pissed that I flashed ts10 and after 2 reboots, it's as good as when I've first bought it! Works 100% now!

Thank you so much and happy holidays!
[Nexus 7 (2013) General] mj0528:
After flashing just about everyone available, I tried to exchange mine but best buy is dumb. They told me it was an app that caused it. They gave me my cash and my return warning. So glad I got out of there with my money since they have changed their return policy. I'll probably never shop there again.
[Nexus 7 (2013) General] niteh@wk:
Amazing fix! This is my third Android tablet and the touch screen issue seems to follow me on every tablet I bought. My previous tablet was the Acer A100. The touch screen was so unstable that it was unusable. I bought this N7 hoping for a better experience with touch screen. Just my bad luck until I found this amazing fix. After applying ts10, forced shutdown/reboot (it was bootlooping at the boot animation), rebooted again and voila, touch screen is working perfectly. Now I can play Asphalt Heat without slammin the tablet (not really but really close to do that). Thanks a bunch for this fix!

Have a safe and merry Christmas!

Edit: after further testing with ts10, there's a line about 0.5 inch wide (1 inch from the camera border) where the jump goes crazy. This occurs after using the tablet for a while. Rebooting fixes it, but it occurs again after some time. Same area. But this is better than before I applied ts10.

Around the time 4.4.2 was released I also opened the nexus and tried to do the other touchscreen fix but I didn't really understand [MENTION=372570]GSLEON3[/MENTION] 's fix and instead just tried to wiggle in the connectors which I guess did not connect them better but in fact loosened them even more. Yesterday I read through the other thread again and saw some photos, with the help of these photos I tried to reconnect the connector again and now I can actually type again on my tablet. For everyone with problems, opening and reconnecting is pretty easy if you know what to do and where to do it.

Oh and no ghost touches anymore (knock on wood) but it might be to early to tell because these didn't happen very frequently

This worked really well ts10 was good enough for my brand new nexus that came with 4.3 and updated to 4.4.2 i would say 60% better

Would anyone recommend me to try another ts? Ive skimmed at bit and see good things about ts14

Really awful we must fend for ourselves on these type of situations Thank you OP
[Nexus 7 (2013) General] marsaltito:
i had same , and when i open it (just for fun to see) i checked couple things why !?

and long story short, it was that tape around speaker that giving strange sound , i just put 1/2mm extra black tape around speaker and now is gone !

after that is gone i didnt open N7 .

ps. and i had light leak on the top and that is gone to :) , i think it was presure from extra tape that fix leak now im happy :cowboy:

just hope you dont destroy or damage your N7 with trying to fix that !

Did anyone notice the camera having more noise to it after this flash?
[Nexus 7 (2013) General] konradsa:
To the OP: you are a genius, Sir. Since I spent Christmas sick in bed, I noticed that when placing the tablet on a pillow that the touch screen becomes somewhat non responsive and fails to detect certain touches.

I installed t10 and as far as I can tell, those issues have been resolved. I really don't understand how you found out how to fix this or why Google cannot include such a fix in an android update, but I am glad I found this post. Thank you!

Ok friends I too have a problem with my touchscreen :(

I thought it was kernel related but know it happend to me after new years eve even on clean rom and elemental x kernel :(

The problem i have is not that only i had ghosts,missed touches etc. buy...my ts is totally out of function,i can't even reboot tablet,unlock,in recovery flash something etc. :(

I would not mind if i had few missed touches but i can't even flash custom roms from recovery couse of ts completelly not working(only some touches registered)...

My tablet is maybe 10 days old,should i return it couse it's not few touches missed or multi touches?Thank you in advance for your help

ps. Putting it on a charger or usb or holding it doesn't change anything,it's totally bugged :(

This happened for second time,first time i thought it was kernel related and after sometime it repaired itself and i managed to flash stock but now it happened again for no reason on famous rom and kernel combo :(
[Nexus 7 (2013) General] mdamaged:
It could possibly be a loose connector, IMO, since it is so new, I would revert it to stock, relock the bootloader, and take it back for an exchange, if for some reason you cannot take it back, or simply do not want to, you can do what this user did and try and fix it yourself.
[Nexus 7 (2013) General] jayochs:
so i've had the N7 since launch and mine has been fine..had an issue once where it wasn't registering touches too well, but i rebooted it and it's worked fine ever since...and i'm stock too, never even rooted it.

but i got my mom a N7 for xmas, and now hers is having issues where it just doesn't register touches randomly around the top portion of the screen (from midsection up) and will work once you shut the screen off and turn it back on. this def is a software issue, and it's running the latest version of kitkat.

i did the multi touch test and saw that it wouldn't register those touches immediately, but there was sort of a lag for when they were finally registered..but then moving it around would yield a ghost touch somewhere in the middle too. again, turning the screen off and on completely fixed it.

i really don't wnat to have to wipe everything on hers and root it just to install this fix, but what do you guys think?
