Phantom touchs

I've been dealing with a phantom touch issue with my shift. Pefectly centered in on the botto of the screen where it hits the phone button in sense. Its looking like a hardware issue.
My question is, has anybody else experienced this and has anybody dealt with taking a rooted phone back to sprint for service?
Thoughts?

I had a weird issue where an area (the left side of the screen 2mm strip) on the touchscreen didn't work at all. I used the one zip RUU back to stock and brought it in and they gave me a new slider (whole top portion). Just happened 2 weeks ago.

I have bad problems with that and screen protectors, especially when it's really hot and humid (like everyday here in tampa)

At first I thought it was the screen protector, but the problem persisted after I stopped using them. And then I thought it was a bad rom or rom install, so I tried 3 different ones with no change. So ill just update myself to the OTA GB and take it in for service.

Did the rooted update to GB and it seems to have gotten rid of the phantom touch issue. I ended up having to do a factory reset when I did it, so maybe that helped. Glad I don't have to deal with customer support now. There always seems to be a line when I go in.

Just want to say you're not alone, this happened once temporarily on my G2. It made pressing the "s" and "a" keys on the on-screen keyboard almost impossible!

Screen tearing fix?

I remember reading a few days back about people having issues with screen tearing. My screen will display a symptom where it has a jagged line shoot across the center area of the screen real fast and then go away. I was wondering if anyone found a solution to that?

No progress has been made, yet. Some think it will be fixed in a software update. When I notified Google support of the issue, they thought it was a hardware problem, but if several people have the issue, maybe it's software.

I'm hoping it is fixed in a software update. That is literally the only issue I have with the tablet.

Yeah I hope so too, but I already have a replacement on the way. I have some other issues with mine though that I felt warranted getting a replacement.
Does the tearing happen to you all the time or just in certain apps? It only happens on mine when I'm playing music. It will show up for a split second as a quick horizontal line then disappear. The line appears in different areas of the screen each time. I notice it the most when it happens in Chrome, but I've seen it on the homescreen and in other apps as well.

Mine happens frequently throughout the ui. Xda app, chrome, everywhere really. If it is a software issue though there really is no point in exchanging. It seems to happen more frequently in an app with a light background.

Mine happens in chrome pretty regularly as well. Could it be something with the video drivers for this thing?

So apparently it was a bad kernel that I was using that caused the problems. Flashed a completely stock build and the problems are gone. To the people that chimed in and said they had the issue, are you on a stock ROM or did you change that and the kernel?
Sent from my Nexus 7 using xda premium

I've noticed this, but it's only happened twice (so far), Once was whilst using chrome, the other time just sat on the homescreen. I'm currently using stock.
(Not too worried, just as long as it's not a line of pixels about to give up the ghost as some other people have had).

Happens to me on stock rom. My N7 is not rooted or unlocked.

Pretty sure this only happens when you force GPU acceleration. I had the same issue, turned it off, and never saw it again.
Of course I love GPU acceleration too much to leave it off, but a jagged line every once in a while is not a deal-breaker for me.

Glad it worked for you, but I don't have that option on nor any other's enabled in the development menu. Regardless, the issue persists.

Is there anyone else having this issue?
I received a replacement today, but I couldn't escape defects on that on that one either. I'm trying to figure out if I should hang in there for a fix on the screen tearing/horizontal line issue, or if I should just send both back and call it a day.
Sent from my Nexus 7 using xda app-developers app

I just found this thread. I have the same issue. I'm on stock kernel, unlocked/rooted, and stock rom. I don't have GPU acceleration forced.
Any further ideas? Could be a driver issue.

People here think the screen flickering issue could be resolved in software, but I'm not sure about the issue we are having.
I might go through the unlocking process just to see if the horizontal line stuff happens on other roms/kernels.
I really hope it can be addressed in a software update. I just struck out on my 3rd nexus. All of them have screen defects. All have had other issues like creaking and slight screen lift, but those are a lot less of a problem to me. The original one is ok except for the horizontal line issue. My two replacements each have dead pixels and dust in central areas of the screen.
This is ending up to be a very tiring and disappointing pursuit.

If it's a software problem it's likely to be in the tegra3 proprietary driver blobs. If this is indeed the case, changing rom and/or kernel will make little difference (because they share the same blobs).
It might be possible to work around the issue outside of the blobs but its likely only nvidia can fix the root cause.

Hopefully someone at Google watches some of these threads. I have 2 nexus 7s with this issue. Thanks for trying to save me the time of trying a different ROM/kernel, but I might still try a CM10 build for kicks.

My first tablet had one dead pixel and it had this issue too. My second one is perfect except for this problem. It probably does have to do with the tegra 3. I hope its a software issue because this one is perfect except for that one problem. I'm not rooted nor unlocked and no force GPU rendering either. It only occurs on some apps with mine. Tapatalk, facebook and barely ever on chrome. I haven't seen it on any games or video nor on the home screen. There should be a place to report this to Google... I doubt they are searching through xda looking for every little problem. I've had this issue for a while and have been searching specifically for bit and just found it today. Also I never see it in horizontal mode.
Sent from my Nexus 7 using Tapatalk 2

I have this issue too and I think it's likely to be a driver issue as it appearance seems random and sporadic in frequency, but it's always really hard to tell about these things.
In any I'm guessing some people just don't notice this issue and thus haven't really talked about it. But it sure is discomforting seeing it.

I seem to suffer from this too.. Everything is stock on mine, no mods, no flashes no unlocks.. It appears to be worse when its been on for a long time.. Wondering if its heat related?

calibrate screen sensitivity?

Hello everyone,
Curious if anyone is having the same issue as me? I have tried multiple roms, stock, with and without kernels.
I am having some touch issues. Either I have to press harder then normal at times or multiple times for my press to register. Its getting quite annoying. Not sure if this is a defect or if i can modify something within the system files to make the screen more sensitive or if there is even a way to re-calibrate my sensors/screen?
Thank you in advance,
DFL

Did you figure out what was wrong? ... It just started to do the same with me... Even to right this was a pain in the a$$...

hmmm... wiping cache fixed? i bet systemcleanup active would help then. I will take your advice and try out that app systemcleanup on my tab. I use on my phone Nexus S just didnt think the N7 would need it due to its specs.

Has anyone decided if this is a hardware or software problem? I've started having the same issue. Turning off the screen sometimes fixes it for me but not always. A reboot always fixes it.
Like just now... I was playing Zenonia 2 and in the middle of a battle I suddenly couldn't get the touchscreen to respond. I hit power to lock the device and immediately tried to turn it back on with power again... but I couldn't even get the unlock screen to work. I set it down for about 30 seconds and when I tried again it was fine. I pulled the game back to the top and it worked fine.
When this happens the "soft" buttons (back, home, etc) always seem to work just fine, so I'm inclined to say it's really a software problem.
Running stock + root.

My thought is that it has to be a hardware issue, or if everyone with the issues is rooted than it could be from the root. My device has fantastic response however I am not rooted.

I would think hardware as well, but the home and back buttons always work and they use the same touch surface...

I got the same thing here and rebooting appears to fix it. Sometimes it is so bad that I cannot move icons from one screen to another.

Did you guys try flashing stock 4.1.1 using fastboot or the toolkit? If that does fix it then its probably hardware problem.

I had the same problem ! solved by turning off the screen and turn on it

I have the same issue and mine isn't rooted yet so I don't think it is an issue with that. A wipe of the device doesn't help but a reboot usually does. This is my second N7 as the first was a warranty replacement for the headphone jack issue. The first never had the issue so I think it is an issue that should be addressed. I am outside my 14 days so I might have to go through Asus now.

For what it is worth, I just called Google and they are going to send me a new one. The lady that assisted me stated that she has had a few complaints with this issue and that they just replace it. N7 #3 should be on the way in a couple days. For some reason she said that the device wasn't set up properly in my profile so it will add a couple days to the process because of the long weekend.
Not a big deal. I have lived with it for a while now. At least they appear to be taking care of it and I wasn't transferred to Asus. At least yet.

From what I've seen, others with similar problems have returned their Nexus 7 to the store they got it from and exchanged it for a working N7. I would recommend you do the same. If you got yours from the Play store, start an RMA. If you got it from a B&M store, exchange it.
Since you've only had your N7 a week, you shouldn't have any problems exchanging it.

It seems like it's an issue with the touchscreen itself. I have no idea how to verify or solve this issue, though. That's why I would personally exchange the N7 as defective. I would think that since your problem is clearly demonstrable, it would be easy to exchange or RMA.
But there may be a solution around that someone else has heard of. If anyone with greater knowledge of touchscreen issues wants to weigh in on this, please do.

I just started seeing this issue. At first it was only happening within apps. I thought it was issue with maybe stretching the app to a larger screen. But I started seeing it on the home screen.

There was a fix posted here somewhere for a package called surfaceflinger-fix.zip you flash in recovery. Made a huge difference on the touchscreen non responsive issue.

I have also experienced this. I I didn't try turning screen off then on but I rebooted then it was fine again.

[Q] Touch detected incorrectly right after power on

This has been happening since I remember getting the device. About 3/5 times when I bring my device out of standby and I go to enter my pattern the touch is off. I have "show touches" enabled in developer options to verify this.
When I put my finger on the top left dot of the 3X3 pattern, which is around the middle-left of the screen, it is detecting that I'm touching the device all the way in the top left corner. If I drag my finger around the screen, the touch is offset. If I remove my finger from the screen and place it back on the screen, then it is properly detected.
I didn't run on stock for very long, maybe an hour or two, before I rooted and flashed AOKP. Right now I'm on WhiteHawkx's unnoficial AOKP nightly and Franco's Kernel (r122).
My plan is to flash back to stock and see if it still happens then. But currently I have a really busy week ahead and don't have time so looking for insight.
Anyone else experience something like this?

No one? So I guess I should call Google for a warranty exchange?

Let me know your results. If it persists, I might have to send mine back.

I'm on stock ROM. I have this issue too, when I power on and drag to unlock, I get a delayed mismatched response. I have to power off then back on again.
It started this recently, so might be app related.

Turn on " show touches" in developer options to help verify if you the save thing happening.
I don't have to reboot mine but I have to lift finger of screen and put back on to get it to properly detect where the touch should be.
Sent from my Nexus 4 using xda premium

So just as a follow up I reverted to stock for 5 days and didn't see this issue. Flashed back to AOKP and Franco kernel and now it's happening randomly when I go to hang up a call. I tap on the red hang up bar and it detects the touch in the top left corner.
I called Google play support but since I didn't buy my device from them they directed me to lg.
I'm starting to think it's my screen protector.
Sent from my Nexus 4 using xda premium

lol, I had insensitivity issues on the bottom of the screen way back, I use a displayed pin pad on lockscreen so I just tap a certain spot to unlock, I sometimes wonder why the digitizer register incorrectly.
flashing a different kernel helped, I'm using motleys.

Have had this problem since launch, im on stock rooted, maybe its a certain app?
If anyone wants to compare their apps with me to find a similar problem, shoot me a pm
