The situation is this: When I start up the tablet, I can unlock the screen without a problem. The tablet behaves normally until a few minutes have passed or until I lock the screen. After either occurs, the tablet doesn't seem to want to respond to swipes or taps. If I try unlocking the tablet, I get no feedback or response from the lock widget. I can't tap icons on the home screen, nor swipe between pages in applications. The software home/back/application buttons are still responsive, which I find quite odd. In addition, if I attempt to power off the device, I am able to hit the "Power off" button to power it down.
Simply restarting the device does not help. I have tried viewing the logs using adb logcat, but nothing interesting (such as a crash message or anything else) appears. I tried a cold boot, but to no avail. I tried resetting the device to factory settings this morning, but no luck there either.
I'd really like to continue using my tablet, so if anyone could offer any advice to help me out, I would really appreciate it!
UPDATE: I turned on the developer option that allows you to track where your touches are on screen, and even when the widgets aren't responding, I see the touches. That leads me to believe the issue is not hardware related. I also see a point at the top of the device (where the desktop indicator is on the home screen), so maybe the device is getting some "ghost" touch up there which is confusing it?
This issue seems to be prevalent since the official Jellybean release. I too experience this from time-to-time, however there is no frequency/consistency to it whatsoever.
Just out of curiosity, are you a rooted user?
