N7 Not Recognizing Touch EXCEPT Notification and Navigation Bars

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

Im having the same issue with mine..just got it afew days ago and it just started about an hour ago. I think its a screen issue cause now it keeps coming up with the menu to change wallpapers without me touching it. And its been locking up alot. Might have to RMA it.

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.

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.

If you were having screen flickering issues are they gone on 4.2.2?

I'm on 4.2.2 now and I can no longer reproduce screen flicker by scrolling fast in Music, nor by using WiFi analyzer. Since it was always an intermittent problem I was wondering if 4.2.2 fixed it for anyone else.

Is the flickering you're referring to the same as when the tab starts up?

I don't think so. The flickering I am talking about happens randomly during use, but I can reproduce it by opening the signal strength view of wifi analyzer, or by scrolling really really fast through a playlist in Google play music. I have not been able to reproduce the screen flickering in either since updating earlier today.

Screen flickering issue?

Is anyone experiencing screen flickering issue? While playing subway surfers I can see some while horizontal lines moving on screen. I don't seem to find it while using other apps or watching videos.

Getting the same thing and only after their last update to fix the black sky issue. It's not happening anywhere else, so I'm guessing it's an issue with the game.

Just turned mine on and no issues , anything certain you do to cause this to happen ?
Sent from my Nexus 4

No I dont think so. I've noticed it back in january when I bought the phone. I even had it with my old Galaxy S with every 4.2 rom and my friend has the same issue with his Nexus 4. The keyboard is responsive but very slow. I can live without the gesture but its very annoying because I love that feature.

Well it does appear to cause me allot of issues if it is on while playing a game! (CSR racing)
