Hi guys,

first off new to the nexus 7 (first tablet, yay)

I been reading about all these touch screen issues for this tablet and thought I was fortunate that I didn't really have much of a problem. I occasionally would feel like my touches would "stick" occasionally.. but it was never enough to really confirm my feeling vs just my imagionation.

Now I wanted to stay 100% stock but rooted and when I got my device 4.4 was just released (the 16O build) I flashed it via fast boot and off I went.. Then S came out, I took the OTA but then had a few Force Close issues so I wiped my device and flashed the 16S build through fastboot..

Around the same time I installed a screen protector. I noticed my screen felt less senstive, missed keys when typing, also noticed sometimes I guess I would get a phantom touch - my screen would zoom in even though I was trying to scroll. Honestly I just attributed to my new screen protector.

Tonight though my screen was really bad I was trying to swype and kept getting letters instead of words. I decided to check out the developer tool show touches option. Holy cow basically the whole bottom part of my screen just "skips" when trying to swype!!

I was getting super frustrated because this device feels unusable when I know it used to work when I first get it (4.4 build 16O)

So for a test I flashed PSX, currently their build is still the 16O build.. Flashed it and factory reset. No more skipping, touch screen is sensitive again and works like it should...

Now the question is maybe PSX is running some kind of tweaked touch screen drivers or google did change something in the S build.. But I just wanted to relay my experiences incase someone else is as frustrated as I am / was, and also find out if anyone else has noticed this - I really rather run stock but PSX is close enough I am sure I can be happy.

Edit*** Interesting so I reinstalled swiftkeyboard - and terrible touch screen issues again.. I went into developer options and enabled the show touches option again - sure enough bottom of my screen was unusable again.

I uninstalled swiftkey and problem went away =/

Crazy.

Ugh. My touch screen has gotten really bad after kitkat. I'm way outside return window.
[Nexus 7 (2013) General] Coronado is dead:
4.4 made my touchscreen go nuts after a while after every reboot on ts10. Trying ts09 now.

Stock has dead spots like it has always had.
[Nexus 7 (2013) General] Sun4ez111:
Please, recompile it for 4.4. Thank you!

Please, recompile it for 4.4. Thank you!
[Nexus 7 (2013) General] fastson:
I want to thank the OP for this fix.

However, once I got 4.4 my touchscreen has become wonkers again. I was using ts10 before 4.4 without issues. 2 days after I updated to 4.4 I started noticing ghost touches, and now I have a dead spot just by the address field when using chrome. Nice!

I tried different TSxx but so far none have done the job.

I wonder what Google changed between the last update and this one? :crying:
[Nexus 7 (2013) General] sfhub:
I don't know what has changed, but there are a couple of units that have shown this behavior now. If you never unlocked, it isn't the touchscreen software itself, so maybe it is some forced low-level recalibration.

I've had luck using ts09 to make things usable again on one unit that behaved this way with 4.4. It didn't work as well as with ts10 but was usable. The other unit is working fine with ts10 on 4.4.
[Nexus 7 (2013) General] fastson:
Thank you. I have now loaded ts09 and I will give it a try. From the short tests I just did the touchscreen (YAMTT) did spaz out a bit when my fingers were parallel (tablet in portrait, fingers parallel in vertical). We will see if I detect any ghost types or dead zones, possibly the two most annoying things in the history of things. ;)
[Nexus 7 (2013) General] WillPoz:
Well, I thought that TS10 had fixed my touchscreen issues but aver several days of being on the screen started to act up again. A reboot seems to fix the problem for a while anyways. I might try the other ones just to see if I get the same results.
[Nexus 7 (2013) General] sfhub:
Instead of reboot, try turning the screen off and on.
[Nexus 7 (2013) General] sfhub:
BTW was able to help someone who's touchscreen went completely dead after JWR66N->KRT16S OTA flash (he was totally stock, not even unlocked)

Essentially what we did was flash JSS15J factory image

https://dl.google.com/dl/android/aosp/razor-jss15j-factory-2e08b83b.tgz

After that the touchscreen still didn't work.

Then we installed the ts10 touchscreen software.

At that point the touchscreen started working again.

When I get back I will try and see if this same procedure will cure the problem with some units not responding well to ts10 once kitkat is installed.

[Nexus 7 (2013) General] fastson:
Hmm. Since TS09 didnt solve the issues completly (it is very similar to TS10) I tried what you said, turning the screen on and off once the touch starts spazzing out. It does solve the issue, but once the electrostatic or whatever is causing this builds up again it starts spazzing out.. untill I reset the screen.

Damn google, go back to how it was in 4.3. I never noticed this stuf then after having TS10 installed. Very very annoying.
[Nexus 7 (2013) General] airmaxx23:
I had a few touch screen issues on 4.3 but 4.4 is a lot worse for me. When I'm using the keyboard I get a ton of ghost touches for wrong letters, backspace, enter...etc.
[Nexus 7 (2013) General] bswpt:
[MENTION=1299673]sfhub[/MENTION]

wow!!!! I had all these issues and already i'm already communicating with google about replacement.

I'm using the tablet often with a pen to hold handwritten things in place and also i can confirm to ghost- and none-touches on google-keyboard or other app-buttons.

Now i found this thread, flashed ts10 - and i must say - the issues are gone!!!!! That's really great!

Just for interest: i'm on latest nightly cm 10.2

Thank you very much!
[Nexus 7 (2013) General] sfhub:
Well, I couldn't get ts10 to work as before, but ts20 works ok on the problem unit after backing out to JSS15J.
[Nexus 7 (2013) General] hhkb:
I have a month old N7 LTE, September manufacture. I had some very minor touch problems. With the 4.4 update it's gotten really, really bad. Complete vertical bands across the tablet go dead for like a minute. I'm going to try this out and see what happens.
[Nexus 7 (2013) General] thecapsaicinkid:
Picked up a replacement N7 today, manufacturer 08/2013. Dead spots all over the screen when not grounded and a stuck blue pixel. ASUS are churning out junk, took a refund.
[Nexus 7 (2013) General] dazed1:
Hey guys Android noob here.

I'm noticing some sticky touches, and ghosting on my Nexus 7 2013, so i was thinking to try out TS10.

I need some answers.

1. Can i go back or try other driver if TS10 does not work, i heard it worked for many users. Does that sill counts for 4.4?

2. Is there any cons if i get TS10, and solve the issues? like does fixing touch, bring some other issues?

3. Is the difference very noticeable, or is improvement but not huge?

4. Is there anything i need to do before i try this method?

Thanks
[Nexus 7 (2013) General] sfhub:
It is easy to try and easy to go back.

The changes are noticeable but it also depends on your touch screen whether it will be satisfactory.
[Nexus 7 (2013) General] doubleho:
god, i was fed up but the ghost touch of.krt6s, was.perfect on krt6o

i tried ts10,20,30,nth help

and so i removed my screen protector last night and flashed ts10,and my.tablet is back to perfect,over 24 hrs,no erratic touch,ghost touch, not recognized touch slide, you name it,everything's gone
[Nexus 7 (2013) General] aritro88:
from all the posts about the ghost touch issues of the nexus 7, it seem to me that only the US bought ones have that problem.

its been a week now and my device is still perfect. i mean if there were issues, it would hav started already............
[Nexus 7 (2013) General] sfhub:
I'm pretty sure there have been people who purchased in Europe as there have been posts mentioning stores that seem to only operate over there.

If it is perfect be happy, but also make sure to upgrade to the latest version because usually when things go from good to bad it is after an upgrade from Google to "fix" the problem. It depends on the touchscreen variance though. Some "fixes" will fix the problem for certain screens, show no difference (good or bad) on other screens, and make worse for some screens.
[Nexus 7 (2013) General] sfhub:
If you are game, try putting the screen protector back on. Perhaps the internal calibration is best done with the screen protector off, but after that you can put it back on.
[Nexus 7 (2013) General] dazed1:
Wait, i don't understand. You want to say, that after you remove the protector it was all good or what?

Because you said you tried TS 10/20/30 and nothing helped, then you flashed ts10 (again) and it helped? i don't understand.
[Nexus 7 (2013) General] sfhub:
I think he had it working fine with ts10 and an ota upgrade to krt16o, then at some point he wanted to try out the touchscreen software that came with krt16s so unlocked, did the krt16s upgrade, found the krt16s software not acceptable and from that point, none of the ts* software would work well anymore.

Finally he took off his screen protector and reran ts10 and it is working great on krt16s

I might have got the ordering off slightly of the versions or the sequence of events, but that is the gist of what happened as I can recollect without going back and looking at past posts.
[Nexus 7 (2013) General] doubleho:
yes exactly,if u hv a cheap screen protector,try taking it off,it might work,ofcoz i cannot guarantee it works on every device and screen protector,but at least it works on mine,with ts10
[Nexus 7 (2013) General] ivan84gt:
I am on CleanROM LE 2.1 and was having some touches not registering. I tried ts10 and so far seems perfect. You sir are AWESOME, thank you!
[Nexus 7 (2013) General] Matrix_19:
With KitKat... which fix is the best one ?

I tried 10,20,30 but no one is fine for me.

edit : damn, TS11 fixed all my single touch issues (when not grounded) but multitouch is 10x worst
[Nexus 7 (2013) General] dazed1:
I got no multi touch issues, only ghosting, and sticky touches, i hope TS10 works good with Kit Kat :)
[Nexus 7 (2013) General] Matrix_19:
OK I got it

After kitkat, my single touch issue was only on the edge, right side, where I could lose contact very often (grounded or not)

and also , when not grounded, I had tiny dead zones all over the screen.

the multitouch was pretty fine except for a little zone in the middle and the sticky touches issue was solved with the kitkat update.

So in my case, I didn't care about this multitouch issue (as long as it doesn't go worst), but I was trying to fix the single touch.

So far, I tried :

ts03

ts09

ts10

ts11

ts12

ts14

ts18

ts20

ts25

ts30

ts09 was almost perfect (no single touch issue, and the multi-touch was close to ok, but not perfect)....

so I tried ---> ts08 <--- and we have a winner here

thank you sfhub
[Nexus 7 (2013) General] hahuhe:
thank you for this fix.

I am on kitkat. never realized i had issue until i start playing games, with the tablet lay on the bed. unresponsive touchscreen unless i charge it, or lay a finger on the side of the tablet.

i used ts10, and it solved my problem.

again, thanks!

edit: after 3 days of perfect screen... now another problem arises, i have ghost touch, but only when i touch at one point on the screen and when i dont hold the tablet :( so sad. however, after a simple reboot, its gone
[Nexus 7 (2013) General] Matrix_19:
damnit, ...it was too good to be true :mad:

ts08 is the best I can get with my tab. No more single/multi-touch "standard" issues...

however, since yesterday, I started to notice an imprecise touchscreen...

It's harder to press and hold (20% of the time it doesn't work) and harder to click on little links in Chrome for example.

I wasn't sure if it was for real, so I downloaded this app : "CalibrationTest"

when I use my finger to make only dots on the page, if it is only 1 dot, it doesn't make a green line.

The first image is with my default touchscreen with kitkat,

The second image is with ts08.

I made 50 dots with my finger, all over the screen, with both cases, and you can see the result

so.................. now I have to choose between imprecise touchscreen or my single touch issues on the edge, right side.

:(

EDIT : well, on second thought, I'm going back on ts09, the multi touch is not perfect when not grounded but the touchscreen precision is better than ts08 and the single touch is fine. So maybe it's the best I can get :)
[Nexus 7 (2013) General] VnnAmed:
Hi there unhappy N7 13 users. I made entire thread describing my fight with touch issues so will only paste here:

Summing up I think about sending my N7 for a third repair but I talked with guys from ASUS today and I don't think it would help... I think about flashing one of those files but... Honestly? I'm just angry with ASUS and really would like my money back.
[Nexus 7 (2013) General] Matrix_19:
I understand your feelings, you are 100% right... but seriously... Just stop fighting, it's hopeless with Asus.

Just install one of those files, the one that will fix your issues and then and enjoy your tab and be happy ;)
[Nexus 7 (2013) General] mertzi:
I agree with matrix 19, try it. It's worth it. Asus will only RMA ie send it to a service point where they will do nothing and send it back. This is my last Asus product.
[Nexus 7 (2013) General] Matrix_19:
after a complete day trying *ts09* I'm sticking with it... it's working great :good:
[Nexus 7 (2013) General] sfhub:
While there are units that work perfect for both tapping and multi-touch on a table, there are also some where the multi-touch doesn't work perfect while on a table.

Many folks come to the conclusion that they hardly ever use multi-touch without holding the tablet, while they often do tap the tablet while on a table.

Therefore they prioritize tap performance on a table over multi-touch on a table which they hardly ever do.

The other issue some units have is they start behaving badly after a couple of days. Often you can resolve that by turning off the screen and turning back on.
[Nexus 7 (2013) General] lomonic:
Being adventurous, i tried the fix listed here http://xdaforums.com/showthread.php?t=2535835&page=6 and all my troubles are now over.

While fiddling with software fixes from sfhub helps with some, those who are a little more bold with their hardware might wanna attempt the simple fix by easily opening up the case & fiddling with the cable (takes only 5-10 mins). Works for almost 100% of users who did it.

Am back on 4.4 stock and not a single problem on surface or handheld.

---------- Post added at 01:59 AM ---------- Previous post was at 01:54 AM ----------

try the sfhub's files or DIY (5-10mins only) am sure it will help ya

[Nexus 7 (2013) General] player911:
That didn't work for me. My cable was nice and tight. I removed it for laughs and reseated it. I got 2 clicks. Still same erratic behavior.

Sad.

I don't even use my N7 much because of this. Sfhubs fix made it usable but it still is aggregating compared to other devices.

Kinda getting really pissed seeing how Kitkat didn't fix it, well I don't know personally. Don't really feel like going way out of my was to unlock, wipe, flash, test... Only to just end up flashing back.

Typing this was even painful. I haven't used my N7 much because of this problem since I got my G2. This is the first time in a month and its still got issues.

It felt much better after Sfhubs fix but not 100% yet. Sad. I can't play games on it, so why did I sell two 2012 N7s for one of these? Real sad.

Is Asus giving refunds? I'm tired of waiting around. Google and Asus aren't even doing anything about this.
[Nexus 7 (2013) General] doubleho:
hv u tried removing the screen protector?
[Nexus 7 (2013) General] Matrix_19:
I think that for this device with so much different touchscreen issues.. Putting a screen protector on it is a very bad idea. It can just make everything worse.
[Nexus 7 (2013) General] hhkb:
Just thought I'd update after using ts10 a few days now. It managed to eliminate the dead band problems, and I got very similar behavior to pre-4.4 (occasional dead presses). But just today, I started getting ghost touches like crazy when doing multi touch. Never happened before. Screen on and off did not fix, I had to reboot which has fixed it for now. Next step will be returning it under warranty :(.
[Nexus 7 (2013) General] GrillMouster:
Forgive my ignorance. TS10 months ago and it solved my problem months ago. I have since updated my N7 to KitKat. My screen is still working fine. According to the Original Post, the TS10 would have survived the KitKat update, is that correct? Also according to the OP, using the fourth image (boot-ts-unlock.img) would basically undo the TS10. I was thinking about doing that so I could see if KitKat fixed the problem on my own device (I know it didn't for others, and likely won't for mine, but each device is unique and I want to see for myself). Anyway, I was wondering if the touchscreen files that came with KitKat are still there, or if they never loaded because I had TS10 at the time I updated to KitKat.
[Nexus 7 (2013) General] Matrix_19:
You can try other TS versions

I had the same issue with TS10 and TS09 is better for me
[Nexus 7 (2013) General] sfhub:
The kitkat touchscreen software is still there, just not loaded.

If you run the unlock it will load the kit kat version.

My advice though is to leave well enough alone.

There have been a few units which stopped responding well to ts* files after switching to the kit kat touchscreen software. I had one unit where kit kat touchscreen software didn't work well, then the previously working ts10 didn't work well anymore. I was fortunate to find ts09 worked OK. Another unit was able to go to kit kat and back to ts10 w/o issues.

There is always the chance kit kat touchscreen software will fix things for you.

So the decision to make is whether what you have now is worth potentially losing to get a potential improvement which also has the potential to make things worse.

I am not saying anything in definite terms because I had one unit which didn't react well and another that reacted as expected.
[Nexus 7 (2013) General] player911:
Yea probably. I'm running TS20 and overall it feels good but it just isn't very sensitive. I feel like I have to pound on it to get touches to register. I have the Show Touches turned on and it just seems like it, overall, doesn't respond well. For example, I'll touch a button. Most the time it works but occasionally I will see the Touch, but the button doesn't respond. Other times I won't see the touch and it won't respond.

So it seems like there is software that is "ignoring" some touches because they probably think they are a ghost touch. In my case, I am not only missing a few keys occasionally but also having them ignored as well.

I think I may roll the dice with KitKat and unlock, flash stock, and update naturally... Such a pain.

And I refuse to take my screen protectors off. I've spent good money on those damn things and I don't want my screen getting all scratched up. Plus its a MATTE so it doesn't show fingerprints as much.
[Nexus 7 (2013) General] animania260:
I finally bought a thinner screen-protector. So I took off the old one, I took off the back of N7 and unplugged and reconnected the touch-screen cable. I booted it, used the screen for a while, cleaned it up and put the new screen protector on.

At first there was still issues when not holding it, but a few hours later.... Finally my touch issue are completely gone. I can use it perfectly just like the old N7 without holding it on any surface!

Also all the touch issues went away when I took off the thick ass screen protector I bought from BestBuy.

I've never used these ts files but just wanted to share my experience here as well. I'm on stock KitKat and for me KitKat resolved all the ghost touches so try using the KitKat firmware if you do this.

I bought the TechArmor 2nd Gen HD Clear (for 2013 N7). Same brand I used on the original N7. Only about $13 on Amazon and fast shipping. I still have the original 1st one I put on my original N7 and its still holding up good so they are great quality.
[Nexus 7 (2013) General] hahuhe:
just want to share,

i did ts-unlock and upgraded to 4.4.1. the update did nothing to the touchscreen problem. atleast to my nexus 7 :( my screen becomes unresponsive unless i hold with two hands.

going back to ts-10.
[Nexus 7 (2013) General] Matrix_19:
I did the upgrade to 4.4.1 too...

tried ts-unlock... :

grounded : my single touch issue is the same,

not grounded : it's worse !! multitouch is almost unusable ( it was mostly OK before)

I'm going back to TS09

chances are good that your replacement would have the same or another touchscreen issue(s)

What was your problem exactly ?
[Nexus 7 (2013) General] pioann:
Hello,

I'm not using the ts files and never did, but I had issues with my device (2013 WiFi). After recent updates (till 4.4.0) most of the problems disappeared except for the ground one. I just sideloaded the latest version 4.4.1, and after a few tests, it looks like it's totally fixed! Of course I'll have to make more tests, but that's for tomorrow :)

PS: even though I never used the files from this thread, I wanted to thank sfhub for his hard work and all the help he provides to the community. Thank you man! :)
