N7 Not Recognizing Touch EXCEPT Notification and Navigation Bars - Nexus 7 Q&A, Help & Troubleshooting

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

RMA it? Is yours rooted? Do you have multiple users?

Do you have an otg cable? Try connecting a mouse to it when it does this and see if it recognizes mouse actions.

This is not a question it is an issue with the device. This is appropriate for general.

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.

Touchscreen Unresponsive Sometimes

Hi, wondering if others had similar problems or fixes.
After a while of use, the touchscreen becomes unprecise and quite unresponsive. For example, it becomes difficult to input strokes or use the keyboard. This problem disappears when I immediately sleep and reawake the device.
Any ideas?
Thanks!!!

I have been having the same issue. I really don't want to send it back.
Here is the other thread where this is being discussed

I have the issue sometimes too. Nothing to write home about. I just turn off the screen and turn it right back on and it seems to work. For the money and performance this thing is my new love. I haven't turned on my laptop in 3 days.

Display glitches

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.

[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

Anyone else sometimes experience touches not registering on the touchscreen?

Randomly it seems, when I tap on the touchscreen on my new N7 2013, nothing happens, and I have to repeat the process several times before my touches are registered.
Does anyone else have this problem?

See my thread titled " Another touch issue, with reproducible steps".
Go into developer options and enable "Show touches" and "Pointer location"
If you see your touches registering but the app isn't responding, it is probably a problem with the app. If you see random stuff on the screen, probably a problem with the digitizer or digitizer in combination with the driver/software in this release.
Ive experienced this a few times and it seems to be a software /hardware interface issue with particular custom rom builds ive installed. I know the touchscreen hardware itself was fine when I forced reboot into recovery and the touchscreen worked as normal in custom recovery.

I wouldn't. If you had a Verizon Galaxy Nexus when it came out, you'll remember that it had the same issue with certain points on the screen (lower right hand corner) when using multi-touch applications. The entire screen would either stop seeing input or start going erratic and creating faulty inputs that weren't happening. It isn't a hardware issue, proven by some users experiencing it and some not. The only time I've experienced it is in the Netflix application while trying to choose a show to watch. I re-boot the application and viola, no more issue. Some in this thread even are stating that they only see the problem sometimes after getting the 4.3 update.
In short, it's software and not hardware.
Same issue when not touching with both hands somehow (like if the tablet is flat on a table).

Haven't had a problem with mine. I just got it today, and it's worked like a charm. I bought mine from Gamestop if that helps any.

Touchscreen issue

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

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
