I haven't had a single problem with my tablet until yesterday when after taking it from my bag after a car ride the screen only had some flickering lines on it. After applying a little pressure and hitting it lightly, it turned on, but now it's totally unusable. It didn't fall. What may have caused this?

Maybe the screen connector got loose. You'd have to open it to check.

Has anyone noticed their NC is very sensitive to water on the screen? I find even if the tiniest few drops of misty rain land on it, it's fine for a few seconds and then once I try touching it, the screen totally glitches out and starts detecting spurious touches. If I sleep the screen and turn it back on, that usually fixes it.
In a city like Vancouver this could end up being a deal breaker ;-) I don't expect a water proof tablet but my touch phones like the Milestone and Nexus One have typically withstood little bits of moisture on the screen without impairing usability.
Repeatable test: Open MultiTouch Tester, wet your finger. Swipe it around the perimeter of the screen a few times. Wait a few seconds. Repeat. Wait a few seconds. At some point when you aren't touching the screen, you'll start to see spurious touches appearing on the screen. If you wait even longer for those touches to stop, then the screen will become totally insensitive to all input. Sleep and back on fixes it.
Theyre called screen protectors.. use em.

Can someone confirm if the same behaviour persists with a screen protector?
I don't own a screen protector but I tried putting a piece of plastic wrap over top to test the behaviour. I wet my finger and trace a few circles on the screen through the wrap. I still get the spurious touches even though the water never contacts the screen. The moment I lift up the wrap, the spurious touches stop but the screen is again unresponsive. I have to sleep it off and on before it works again.
Since all screen protectors are some type of plastic or other, I have a feeling this problem would still happen with a protector.
And here is my video showing the "experiment" (no protector/wrap).

Again, same results with plastic in between the water and the screen.

Had the same problems but putting on a screen protector fixed it. No random touches. No need to turn the screen off/on. So much better.
Using this one.
confirmed. it still does it will screen protector. tested with ipad and itouch too see if this was a capacitive screen issue. water had no effect on those too devices. Doesn't really matter because I don't plan using this device outside in the rain.
Well I wouldn't take it out in a torrential storm, but sometimes it's just "spitting" out as it often is in the Pacific northwest, and I'm reading a book or article at the bus stop. And then suddenly it's flipping random pages or launching unwanted apps.

This is probably related to the common phantom touches people get. I know my nook some times register random touches from hovering fingers up to an inch from the screen.
Too much dirt/grease on the screen will also do it. The screen on the NC is (by default) very sensitive.. There are a few methods to "calibrate it", some of which say if you're touching it while calibrating the sensitivity goes down.
I've seen this several times myself, and yeah it's annoying because it goes NUTS. One time I had it remove an app from my launcher, launch another app, then change some settings. I was like wtff gaaahhhhh
No screen protector on mine.. I usually do on devices, just haven't on this one yet.
It's a capacitive screen. A drop of water can make the screen behave strangely because the capacitance of the screen changes where the water is. Multiple drops of water will drive the screen nuts. This isn't new. If you hands are too dry the screen won't register the touch.
It is how they work.......
BN brand matte (anti-glare) screen protector has completely, I mean 100% no lie, fixed this problem for me. In addition, the screen loses it's "tackiness". It's a pleasure using the screen now.
I've seen some threads about this on other tabs, like the Galaxy Tab 10.1, but not on the Asus tablets yet. On my TF701T, I noticed over the past month that when I take it out of the case I have for it (a neoprene case with a zipper), it has a spot in the middle about the size of two quarters that looks like moisture under the glass.
Within a few seconds of turning it on (and sometimes not even turning it on), it disappears by quickly getting smaller and smaller into the center.
All of this, not a big deal.
However, last night I saw something even more odd....the spot disappeared with the exception of a ring of moisture (instead of a full circle) that stayed and wouldn't go away (again, slightly larger than a quarter). Touching parts of the screen would jiggle the ring. It seems like something was happening in the LCD display.
In the past when it went away, I assumed the screen was warming up and causing it to go away. However since it didn't this time, I thought something was damaged.
I saw a bizarre thread somewhere that suggested to put it in the fridge or freezer for a short time and the cooling would make it go away....if I remember correctly, it may have implied that the LCD and digitizer where touching or stuck together. I figured, what the heck, I stuck it in the freezer for a few minutes. When I got it out, it was nice an cold, and the spot was gone.
Has anyone seen this? Anyone know anything about what this would occur and why the cold would fix it?
Thanks,
chris
I had exactly the same issue you described. The moisture spot would always go away eventually. However, one day, while in use, the screen suddenly died. The tablet was still working fine (confirmed with an hdmi cable). I was unlocked, so the tablet became useless. I have no idea if the moisture and screen failures were related or not, but if you are not unlocked, I'd probably try to get it repaired.
I suspect that what you and I have is a gap between the LCD and the digitizer. We have (3) tf701t's in our house now and no moisture spots yet on any of them.
Hope this helps.

Thanks, good to know. I am unfortunately already rooted and running sbdags rom. It is interesting that it only happens when I have had it in the case for a little while. Hadn't happened again for about a week, but started happened again last night. Fortunately, it went away on its own again very quickly. Oh well, it is what it is.

I have also noticed the same spot after pulling my tablet out of the neoprene case. I have been getting itchy to root but now I will hold off. Maybe I should try the freezer fix?
Thanks for post!
ASUS Tf701 moisture ring center of glass
I had this happen in the past, but it always went away when I turned the tablet on. I always store it in a leather case, the screen never touches anything. It recently came back and will not go away. I've been reading threads about putting it in the freezer for a short time....my question is, how long have people left it in there, 2 minutes, 5 minutes? The spot is driving me crazy since it now won't go away.
Thanks for your assistance!

I have the same problem with my TF701T. But I noticed it isn't moisture between the screen but digitizer and the LCD screen touching eachother? If you bend the tablet really slightly towards you, you'll see the "moisture" go away. Don't have to apply too much force. Might be just design flaw IMO.
Just picked up a second hand S4 Active. At times, the screen gets jumpy. It looks as though you are trying to swipe between screens. Also, it will at times go unresponsive. Touching the power button to turn the screen off, then turning it back on with power or home, fixes it.
I am going to take it apart to see if there are any signs of corrosion, and make sure the LCD connector is tight. I really don't think it has water damage, because the stickers are white. I suppose they could have been replaced.
I saw some youtube things that said a swelled battery could be the culprit, but the battery is not swelled at all.
Any ideas on this? It's a flicker - it jumps around. Turning the screen off and on fixes it, so I'm not really sure what the deal is.
Thanks much.
Should have added - it's on stock 4.4.2, if that matters.
I have a Galaxy Gear that I barely use because most of the time when I'm out I'm at work.
In the past few months, I noticed it had issues charging and later issues turning on. I just realized now that the bottom part of the screen is actually popping off causing the watch to not charge or turn on. It turns on when I squeeze it together. If I squeeze the bottom part, it seems the top is also coming off, although not as much.
Has anyone had this occur on their watch?
I'm thinking on taking it apart and using Ultra Gel to glue it back together. That stuff is strong.
Any solution? I have a same broblem.
I have had my Xperia Z3 compact for a bit over a year now, and experienced the "sudden death" problem a handful of times. The symptoms are pretty much the same as everyone else said: black screen, no response to power button, sometimes red light after plugging in but nothing on screen. Thankfully I have been able to revive it reliably by first holding Power + Vol Up for 20 seconds, release, then plugging in the charger.
After the last few incidents, though, I think I'm starting to see a pattern: the sudden death always happened after putting the phone on a metal surface. For example, the magnesium lid of my ThinkPad Yoga 460 laptop, or the (presumably steel) top of a washing machine. Every time I pick the Z3C up and notice it has died, it has always been lying on a metal surface before. However, it does not die every time I put it on a metal surface, so I can't reproduce the issue reliably.
I remember reading somewhere that the sudden death is caused by a hardware bug with power management. It sounds kinda plausible that being too close to a conducting surface may change the capacitance / inductance of something on the PCB just enough to trigger some kind of protection. So perhaps using a thick case may prevent sudden death by making the phone farther away from the surface it is placed on?
