[Nexus 7 General] JaSauders:
I don't really recall this issue happening before (it may have been apparent and I didn't notice it), but I'm seeing it now. What changed? My screen. My screen cracked and ASUS fixed it under warranty. I've had the thing for 3-4 days now and I keep thinking I see it by then it disappears right away. Last night it had dead spots even when I would sleep it and wake it up again 15 times over again.

I find it somewhat difficult to duplicate the issue. At first I thought the "put your finger on the screen when it's asleep, THEN wake it up" thing seemed to be working predictably to replicate the issue, but I just did it a half dozen times without bringing it back.

It's hard to bring it back, but when it happens, it's hard to get rid of it.

C6O, new screen, 4.1.1, rooted, stock.

Truth be told, I have an exceptionally hard time believing it's a hardware issue. That being said, the only thing that changed on my tablet WAS hardware (the screen). The software hadn't changed aside from the fact I rooted and unlocked the boot loader. Aside from that I'm on stock ROM. Even though the signs point to hardware, I still feel otherwise - but now and then I'm beginning to feel very wrong about that. *shrug*

EDIT - so I've been sitting here ever since I posted this above and it seems to be happening a bit more predictably along the lines of what other users have been saying. I'm not sure what I was seeing last night when I was in a borderline tired coma where I felt as though I slept and woke up the device over and over with it still being unresponsive, but it seems to work fine after one cycle now.

There are times where touching the screen before waking up the device causes this. I'd say maybe 3/10 times it'll do that. Otherwise it acts fine and I have no operating issues. Very small price to pay even if it is a hardware defect, so I doubt I'll send mine in since I already just got it back from Asus a matter of days ago for an unrelated problem that they repaired. I'm just glad this issue doesn't require a full blown reboot to fix. And who knows, maybe the next software update will surprise us and fix the issue after all? Any bets on the table?

EDIT II - I'd like to retract what I said earlier about not believing this happened on my tablet prior to sending it to ASUS where I received a new screen. I was tracing my steps back in my head. I use a folio case with my tablet with a magnetic flap which controls the waking up/automatic sleep of the tablet. I've used a case ever since day one when I received the N7. I never had a reason to touch the screen in any scenario with the case, which is likely why I never noticed it. I'm not saying with certainty that this issue existed prior, but what I'm saying is I simply *don't know* for sure due to the fact I always used this folio case. Truth be told it's extremely possible (do I dare say, likely) that it was there all along and because of the case I just never noticed it.

Last night was a different story as I took the tablet out of the case for easier holding up high. I did this because I was trying to simultaneously read with the N7 away from the "danger zone" of the puppy jumping up with a squeak toy to continually play fetch. With holding the tablet in one hand securely my palm was over the touch area, which when it happened to go to sleep and lock itself is when I noticed the issue since during the unlocking process my palm was still on the edge of the touch screen. That was the differentiating event which brought this to my attention.
