Hi Guys
I seem to be suffering from a issue where the touchscreen has a dead spot.
Now I had an earlier issue that caused all sorts of issues with screen responses - ultimately ending in no response unless I hit the power button to lock and then unlock.
That problem lasted about a week and then stopped - my thinking is that there was an app update that solved it.
Now however the issue has resurfaced (seemingly after other app updates) but it is a dead spot roughly where the first notification would be on the notification draw. Any ideas as how best to find out the cause of the issue, or a fix?
I've included screen shots showing the touch trace.
Cheers for any help

I can't help you but with some custom rom there can be a bug with it until I make some setting changes to the Nav Bar, but otherwise I don't know.
Forgot to say that this is stock 4.3

Many people are complaining about 4.3... It's causing many problems

What I don't get is why it went away after the first time.
I don't really want to factory reset if I can help it.
Is there a way to look at an update history for all your apps? Then I can pinpoint the offender.
Sent from my Nexus 4 using xda app-developers app
I've found a solution.
After factory reset and safe mode not helping I came across a comment in another thread.
You have to Disable HW Overlays and Force GPU Rendering. Now its not perfect and can have an occasional fit but does seem to solve the issue

Occasionally, a horizontal or vertical line flashes on the screen very quickly and then disappears. Does anybody else have that? Is it anything to worry about, or does it not matter? Is it likely that a software update will fix this?
Thanks for any replies!
First, are you running a custom kernel or stock?

I have not rooted my device. I have flash installed and Iplayer, but apart from that all my apps come directly from the Google appstore...

Damn it! I was seeing this on occasion and hoped that if I just thought I was crazy I wouldn't have to acknowledge it. Now I see it's not my imagination. It happens only rarely and it's really just a blip, but it is indeed weird. I just unlocked/rooted last night though so I'll have to see if it still happens now...
Always happens to me, really only noticeable on mostly white screens like in xda app.

First device had this issue, took it back (for many reasons), and have not noticed that little "subliminal" black line anymore.
Happens to me too, so far only seen it in the xda app, and in my browser while waiting for a Page to load that is taking a while.... I'm currently waiting for an exchange because I have a slight screen lift issue, but I doubt it will fix this black line problem, it is probably standard on these things. I guess I can live with it

I also get it a lot when playing an online chess game. It seems related to the apps used. Don't know what to make of it...
Sent from my Nexus 7 using xda app-developers app
Could it be a memory leak or a GPU rendering issue as some have suggested? Many of us get this on the stock ROM with no developer menu changes.
I notice it too. I thought I was seeing things. It is not serious enough to give a crap though. I just hope it does not evolve into a worse issue.
It probably has to do with spotty Tegra drivers. I noticed it slightly on Chrome, but never on anything else.

I've seen this quite a bit also. Seems most prevalent for me when I'm using the GPS Status & Toolbox app from EclipSim, except in that app the lines are white.
I think you guys are referring to screen tearing. I have seen it a few times to I think in chrome. Pretty sure its not a hardware problem.

Yeah I get this too I'm hoping its a software issue it doesn't happen often but I seem to only notice it on tapatalk or the Facebook app. I haven't seen it on games or videos.

I get that in Tapatalk once in a while. I would guess its a coding thing and not a device defect.

I have three users configured and at times the tablet seems to lock up. But I can still pull down the notification drawer and setting drawer. I can touch the back, home, or multitask softkeys, or slide up for Google now.
But no matter where I navigate to, the N7 does not register touches in the "screen" area.
I have found that pulling down the setting drawer and tapping the user to "logout" and then logging back in immediately fixes the issue. Also toggling sleep/wake button and logging back in also fixes it.
Is this a known issue? Is this multiuser, software or hardware specific? Any solutions?
(I read back through a couple weeks of posts but didn't see this issue)
--- UPDATE------
Just happened again. But I left it alone for a minute, picked it back up and it was working fine. Perhaps this is app lag. The notification and navi bar work because they're systems but the screen stops taking input while it lags....(just a thought, I don't know how that stuff might work)
BTW I have a 32 GB N7, it is not rooted, and is fully up to date running 4.2.1

Damn. Well maybe get a log cat next time it happens. Maybe there will be something there to show why it stopped working.
Sent from my Nexus 7 using XDA Premium HD app
I'll have to learn how to get a logcat. But I was able to recreate the issue and get a video. I could only get it to affect settings and the play store but I've had this in the launcher before too. I don't think you can hear but tapping the screen was causing the touch sound.

No one has had this issue? I've only experienced it in Settings and PlayStore on me first and second user, nothing on my third user. Also noticed a litte lag on the homescreen too.
In the video you may be able to hear the touch feedback sound. The screen is recognizing taps but not doing anything. Sleep/Wake fixes the issue until you leave the app...
Guess I'll need to exchange my N7 and hope to get one without this issue.
Why did this get moved to Q&A??
Are Issues not discussed in General?
[SOLVED]
I was using APP LOCK on User #3 and that caused what seems like an overlay that prevented touch on users 1&2.
I sent this issue to the apps support. And will try to find a free app locker that is milti-user friendly.

I have a completely stock, unrooted Nexus 4 that I received 2/4/13. I've been having some strange display hiccups pretty much since I got it, and they seem to occur on any part of the screen. Sometimes it will occur as a square in the upper left section of the screen, other times it will be a mess of static at the bottom. Sometimes text entry will either turn all black, or it will disappear altogether. In some of the screen shots, you will notice that I am using an app called Screen Filter to decrease screen brightness. However, the display glitch occurs when I am not using Screen Filter as well. I was wondering if anyone else was having these problems? I'm considering RMAing my phone for a new one.

In another thread it was mentioned that you should check "disable HW overlay" as a possible solution. I did it earlier today, but will have to see if it helps.

Sorry for the bad title of my thread. I tried to describe as best I could, I still have the same issues although not as often. I disabled hardware rendering and the one underneath in developer options. Better but not fixed yet.

Should "hardware overlays" be disabled and "force gpu rendering" be enabled? Do all these measures indicate that the graphic glitches are hardware problems?

Hi,
I have a similar problem with my N4. Did you solved the issue? I hope it's a SW problem that will be solved with the next version of Android and new drivers from Qualcomm because I cannot RMA it...

I'm not sure what the issue was hardware/software-wise. I just sent the original phone back, as I received the RMA last Monday. It seems to be working well overall. Good luck with your phone.

Sent from my GT-I9505 using xda premium
I'm having this issue and it's doing my head in!
Every time I bring up the on screen keyboard the hue changes slightly to greeny tone. Then back again when keyboard goes.
I'm surprised not more people mention it.
The easiest way I found to see it was ten brightness right down, go to a dark room and open play store. Touch on the search bar to bring up recent searches and keyboard, then hit the back button, then touch touch bar again, then the back button. Keep doing this so your toggling keyboard on and off and watch the whole screen shift tone.
I'd love to know if it's an issue across the board or if only a few phones are affected.

I am facing the exact issue bro but i hope it will be a software related issue but i am also worried that may be we have defective handsets because very few people raised voice against this issue so it means that most users are not suffering from this issue.

Sent from my GT-I9500 using xda app-developers app
It's got nothing to do with the keyboard.
If you watch a movie on you tube (black and white is best) put to full screen and wait for slider to dissappear, then tap screen to bring it back. The hue changes to green!
It's whenever the screen has to bring something up like a keyboard, menu, slider etc.
Come on guys please can you test this so we know it's a problem on all handsets like smearing or if it's a hardware fault in a few handsets.

mostly all people have this problem & I was worried too about this. But update your phone. you should get a new update notification by now.! I already updated and it fixes this problem. and the smearing issue as well. And then you can also move your apps to sd!!!!!:victory:
Hi, just got my replacement after having some overheating problems and noticed this problem on the new one. I'm pretty sure is the screen, and not a software problem. Mine looks yellowish/greenish on the bottom. I downloaded Screen Test app and notice the problem. I have some pics showing the color differences along the screen. I'll go for another replacement tomorrow.

Is anyone else having the problem where the owner information is not appearing on the lock screen? (not the personal message, that is working ok for me)
Mine will be there after a reboot, but sometime over the next few hours it will stop appearing on the lock screen. A reboot will make I appear again.
Not sure if it is an app conflict or a system bug that may get fixed in a future update.
Thanks,

Yes, I'm having the same problem. My info stays for a couple of days or so after a reboot, then it just disappears. I was wonder if that was my phone's way of telling me it's time for a reboot, but I was doing a search on it in case there was something else to keep it from happening. Right now I'm treating it like a "Check Engine" light.
Weird, it happens to mine as well.. I didn't notice until I read this thread and had a look! Very strange..
