Xoom touchscreen "has gone mad"

Well guys, I don't know how to describe better this think
These are the facts: this morning I received my new Xoom WiFi from Amazon; I'm in Europe so another courier shipped my Xoom from US ground to my home.
After unboxing it, I charged it and then started playing with it. After a while, I waked up the Xoom from sleep mode and I noticed that there were several "fake touches" per second on the screen, or to better explain, I could see on the display the same reaction that would be if one touched repeatedly and very fast on the screen. This made the tablet completely unusable, or even "dangerous" (it clicked a "Like" button on facebook and sent a nonsense email all alone, without any intervent by me). The first times, I just waited and this abnormal acting disappeared. After a while, a reboot was needed to fix this condition. At the beginning this problem showed up only after locking and unlocking the screen (waking up the Xoom from sleep mode), but after some hours of use it has slowly deteriorated: at this time the Xoom does this always, from when I turn it on, to when I turn it off (and believe me, it's really hard to turn it off) and the tablet it's COMPLETELY unusable.
For now, the problematic part of the screen it's only the left column (holding it in landscape, with the front camera on top).
What can I do?
P.S.: I buyed it on April 5th.
P.P.S.: obviously the Xoom is "virgin", with no hacks of sort, completely stock

Have you tried doing a factory reset? See if that helps if not then you might have a defective unit.

How do you do a "factory reset" on the Zoom?
"Xoom the Monster" The beatings will continue...

If the protective plastic cover is still on the screen, it could be causing problems. Other wise I'm inclined to think there is a static charge involved. It might sound silly, but try holding a metal water faucet with your other hand while you touch three screen.
-Total speculation on my part.

Yes, I did a factory reset: the only result was loosing the songs that were included with the Xoom

It's what I thought too. There's no protective plastic cover anymore: I removed it before turning on the Xoom. However, I've tried with a calorifer before, and I got a shock. Now I tried with a water faucet, touching it for a while and the malfunctioning seems to be gone (for now), but now the touchscreen it's not so precise (or so it seems). However it seems strange to me. I never had such problems with any capacitive touchscreen before. Is it solveable? Is there a way to be sure that this is solved? It's a defective unit?

Ok, it was a temporary solution: the malfunction came back. Then the "holding grounded metal" trick worked again, and then the malfunction came back, and so on...

I have also problems with touch screen, but my problems are much stranger. On my Xoom there are two possibilities if I turn it on, I ether have touch controls or not. Forced reboot is the only things that gets me touch controls at all.
But back to your problem, have you looked if dmesg output shows any errors? Download Terminal emulator app and write dmesg.

I suggest you return it. The components are so sensitive to electricity and there are two huge potential static generators; the battery and the flash capacitor. You could toast it at any time, and might'vs already baked a sensor for all you know.
Take it back fora new one.

Well, I tought about it, but I buyed it from Amazon US and I'm in Europe: I really don't know how to return it; I don't even know how long the returning period is. However, you could be right, so I'll try to talk with Amazon or with Motorola support service.

Forced reboot (not just a reboot) seems to help here too, but only temporary, because after some time (or if I lock and unlock the screen) the malfunctioning come back.
I caught the dmesg log. Here it is an extract during the malfunction coming out
Code:

All I did here was to press the lock button (locking and turning off the screen), press it again and unlock the screen. It seems pretty normal to me. However I have the whole dmesg log (from turning on to force reboot) of that session. I can post it if it can be useful.

The part you posted is normal.
I would be interested to see your dmesg output after a forced reboot, to compare it to mine.

faced with similar issue. Randomly some fake screen touches are taking place. Only pressing the on/off key helps to get it back to normal state. Do anyone have any suggestions or ideas?

Flashed with Tiamat ROM but the issue still remains. Xoom is going crazy.
I'm afraid it's kind of hardware problem, maybe something related with static electricity. Not strong in this.
Can't return it to Motorola as it was bought it US by another person
Anyway, thank you, ryan562
Any other ideas/suggestions are welcomed

Have you applied a screen protector on it that required liquid to install it?
My Xoom touchscreen briefly malfunctioned the other day as it kept thinking I was touching the lower right part of the screen. A power cycle cured it for now, but I hope it does not return.

I applied screen protector, but not very carefully. Leaved some air bubbles. I thought they were causing the issue and removed the protector completely.
Right now there is only silicon case. I was able to reproduce the problem without case

[Q] This auto-dim "bug" is completely unacceptable...and is driving me beserk
Basically, if I turn autodim off and turn the brightness up over 50%, the screen shuts off and when I press power to wake, flashes for 1/10 of a second and then turns off. The only way I can use my tablet with brightness over 50% is when it is plugged in.
How has this not been fixed yet? It's got to be a software issue right? This is completely and totally ridiculous.

I don't have this problem. I use it at 75-100% most of the time on battery.

I have zero idea what it could possibly be. I'm on the verge of returning and just washing my hands of this thing. It's a shame because the Galaxy Tab will definitely be at a higher price point.

exchange it. Something is wrong. No one else is reporting this issue. I've had my ft stock, running Paul's rom and prime, and all the different kernels. No such problem. Sounds like a hardware fault.

This.
I get that people can get frustrated when something's wrong but the store should always be the first point of call if you've got a problem. If you get it exchanged and it still has an issue, THEN you get to post about it and complain. Even so, at least post in the right forum...

I have this problem and I've seen 2-3 other people with it, so its not that common by the looks of it. I tried to find a solution but I am RMAing mine as there isnt a fix at the moment.

Screen wont turn on

Out of the blue - or so it seems - my screen will no longer turn on.
I was listening to music and pushed the power button to change the station and the screen would not turn on.
When I push and hold the power button the phone will vibrate briefly, indicating that the shortcut menu to reboot/ mute the phone has come up, just that the screen remains black.
When I try calling myself the screen will not turn on nor will the phone ring.
When I plug the USB cable into the phone, the screen remains black instead of turning on like it normally would.
The screen will turn on randomly on the rare occasion, but the screen wont respond to touch.
Help!

what app were you using to listen to music with? and why would you press the power button to change the station?

OP give more details about your phone. is it unlocked/rooted or custom Rom? Google replaces unlocked/ re-locked phones anyways, I think it wouldn't hurt to reflash stock image.

Spotify. And I wasn't pushing the power button to change the station, I pushed the power button to turn the phone on so that I could change the station. There is not much interaction possible while the screen is turned off
With any luck it wont happen again. Although I dont normally rely on luck much.

[Q] Touchscreen Issues

I purchased my NVIDIA tablet yesterday but having problems with the responsiveness coming from sleep. About 1/5 of the time, my tablet will not respond to my finger/stylus. I always have to press the power button a few times to get it to work.
I have all the updates, including the recent update from yesterday. Is this defective?
Thanks in advance

I've had that many times during one single day. Had to literally reboot the thing 5 or 6 times that day. COMPLETELY NO RESPONSE FROM THE SCREEN, ONLY BUTTONS. Still have to clue what the deal was. Hasn't done it since, but the issue DOES exist. And yes, I bought from the very first batch, straight from Nvidia.

I've had this problem since day one. Also the tab crashes at random times and it getting ****ing annoying. Thinking of returning the thing. It's worse than useless. Turn the screen off and you can bet that i'll have to reboot to get the touchscreen working again.
Idk why this helped but it did. I switched from using philz touch recovery to cwm recovery...now screen works less than half the time I turn it back on. That's still better than never.

I've never experienced this on Stock, Only on Pac-Man ROM and CM11. Either way it is very annoying.
This is a reaaallllllyy ghetto work around until the issue is solved, but the way I worked around it on CM11 is to have Tasker and Secure settings wake the device for a few seconds every 45 mins - 1 hour. Ever since I've had Tasker performing that task I've had no issues with the screen being unresponsive.

I have figured out how to fix the touchscreen issues. All you have to do is go under Settings>Apps>All Apps and find anything that ranges from Google Taiwanese or any Google foreign language app and disable it. There should be two of them. I haven't had any problems since I disabled them. :good:

I found something that has worked so far. I always use Nova launcher since it's my fav. I didn't think much of leaving the launcher that came with the rom. I went to titanium backup and froze the other launcher and it solved the touchscreen issue. This also fixed the app crashing problems most of the time. Still if I run more than two applications at the same time everything on the tab starts crashing. Seems to be a ram problem. I checked max backround processes and it's at "normal" which usually is fine. If anyone has a solution to the crash problem please let me know. Meanwhile i'll keep trying stuff.

Same problem here... Funnily enough I just wanted to try a custom rom to see whether this issue will be fixed and a new official upgrade to 7.0 came up - https://shield.nvidia.com/support/shield-tablet-k1/release-notes/1
Will see whether ithe problem is gone.

There was a time when my screen became a bit unresponsive. Very random. Calibrating the touch sensor fixed it up. Its a bit hidden but you'll find it by going into Settings>About Tablet (device)>Click on Model Number 3 times>The calibrating settings will pop up hit Touch then hit Start. It'll do it's thing and reboot. Hopefully it helps.

I had a similar issue with touchpoints not working near the corners, calibration fixed things for me also. It's pretty quick and easy to do so I urge you to try that before doing a factory reset.

So far so good... Android N seems to fix the problem

Nexus 5 restarting regardless of ROM

So I've tried factory wiping and installing a few different roms and no matter which one I go to I keep getting these random reboots. This is particularly troubling when I restore an older rom that I know I was not having this particular issue on.
It is making my phone pretty close to unusable since it will often go into an "Optimizing apps!" speil draining battery and taking an obnoxiously long time to reboot. Not sure what is up. Any suggestions?

Try with a clean flash (or the factory images) without user data/modifications and see if your RRs are still there.

The button will NOT seem to be stuck, even if it is, as the contact is made internally. My bro´s Nexus had this problem, and by the end it kept rebooting constantly because the button was making contact on its own. I fixed it by tapping vigorously at the area between the power button and the camera and that made it work.
A way to know if it is stuck could be to press the volume down key as soon as it restarts, if it goes into recovery, then there is no doubt the power button is stuck.
Don´t dismiss hardware problems, as many Nexus are affected by the power button issue and you already tried software solutions which didn´t work.
Hope you sort it out. Remember to use an app to avoid pressing the button so much, such as when waking the device. I recommend Gravity Screen, but there are many other options.

Holding down volume after one reset actually put me into recovery. Plus it's restarting at times in recovery now :/
I doubt it's under warranty since I got it in feb 2014 x.x

If you got it directly from Google, I'd try calling them up and asking for a replacement even if you are a few months off the warranty period, I have read some stories of them honoring warranties in order to get rid of stock. That'd be true even now that the new Nexus is supposedly releasing this year. Nothing wrong with trying, you might get a new, shiny phone.
That being said, don't worry, it's perfectly fixable. The part that gets stuck is not the button itself, but the part that goes into the motherboard, so don't bother fiddling with the black button. I managed to fix my brother's button by doing the following:
- Clean the area between the button and phone of debris or any dirt that could be causing it to be stuck. This is just to be on the safe side, as it is unlikely that it is the cause of the malfunction.
- Take the case off the phone if you haven't, and then put it upside down and tap vigorously with your fingers in the area between the camera and the power button. It might not work the first few times, but it eventually will release the part that is stuck.
- As soon as you can get it to turn on without rebooting itself, install Gravity Screen, or any other app that replaces the power button to wake up or turn the screen off. You are looking to use the button as few times as possible.
After doing that, his Nexus went for being unusable due to constant reboots to working fine. It's been almost 6 months since it happened so it is bound to work, just don't lose heart and patiently work at it. Tap a bit harder if it's not working. Let us know whether you managed to fix it.

- Clean the area between the button and phone of debris or any dirt that could be causing it to be stuck. This is just to be on the safe side, as it is unlikely that it is the cause of the malfunction.
- Take the case off the phone if you haven't, and then put it upside down and tap vigorously with your fingers in the area between the camera and the power button. It might not work the first few times, but it eventually will release the part that is stuck.
- As soon as you can get it to turn on without rebooting itself, install Gravity Screen, or any other app that replaces the power button to wake up or turn the screen off. You are looking to use the button as few times as possible.
After doing that, his Nexus went for being unusable due to constant reboots to working fine. It's been almost 6 months since it happened so it is bound to work, just don't lose heart and patiently work at it. Tap a bit harder if it's not working. Let us know whether you managed to fix it.

I'm going to get in contact with google. I tried pushing down on the area between the camera and it didn't help much. It has started working again properly after a really peculiar work around. I just don't want to have to be super cautious of a button for the rest of the time i own my device :/

Well someone mentioned maybe trying to clean it out somehow. I tried canned air and that didn't do anything so I formed a seal over the button using my mouth and then proceeded to exhale. It has yet to give me any trouble since then.

Had exactly the same issue, reboots over and over again, couldn't boot to bootloader without reboot...
What helped for me was something I read somewhere else, don't remember where, was knocking on the back cover between camera lense and the power switch, did it 4 days ago and it works since than..

Sounds sexual

You can take the back cover off, and if you are careful there is no sticker or seal that would tell google you have opened the device. It is difficult to pull all the way off, the vibration motor is attached to the case back and comes off with it so it would seem stuck. You just have to keep pulling.

Pressing on the area between the camera and the on switch seems to help a lot of people it didn't seems ot have much of an effect for me. While my phone hasn't given me issues since shortly after I posted this thread I'm kinda worried I'm one drop away from the issue coming back

No way to avoid it sounding that way I fear.

Would this allow me to repair it?

Yeah but you'd need to unscrew a plastic cover that is inside the phone. Phillips head screws, jewelers screwdriver size. Depends on if its dirt or a broken switch though.

Sorry to disappoint everyone but this is a widespread problem that google is aware of fro some time now. It's not the power button but it's burried deep in the software and appreas to have popped up right after the Lollipop 5.1 up date. Check out all the posts on Google

While it apprears to be confined to the Nexus 5 I have had it happen with my nexus 4 just running stock L 5.1
I hope that casts some light on it

Weirdly enough, my power button works flawlessly on 5 and 5.1. Red 32gb from the google play store. I've opened the case multiple times and put Arctic silver knockoff heat compound in sloppily and without regard, no issues other than sprint screwing up their spark LTE rollout.

Sorry, I disagree. While some instances might be related to software, it has been proven that there is in fact a problem with the physical button getting stuck on Nexus 5 phones. You can check it online and will find lots of hits and even YouTube videos, most of them around the time before lollipop.
Best way to check whether it is software or hardware is to press the volume down key when your phone reboots by itself. If it takes you to the recovery, you can bet your cat that it is not lollipop's fault

So I'm suspecting that I have the wonky power button too but.....
I haven't been able to get it to go to recovery when pressing power down and I've defintely had a few restarts very recently.
More importantly, and something that I haven't seen anyone else post about; more often than not my N5 just shuts down. It's usually when I've doing something with the phone (today was flicking through my GPM library). I'll power it back on and it will boot cleanly and then (more often than not) power down again. Other times it will bootloop, but that's rare. It seems to me that if I let it boot up and then don't touch it for a while, it will stay up but I'm not sure that's consistent.
Anyone else seen or heard of the power button causing a powerdown instead of bootloop?

You will need to troubleshoot this the old-fashioned way. Have you installed any updates, apps, mods or anything recently?
Best case scenario would be that you flash a stock image without restoring apps, kernel or any mods. Run the phone for some time, couple of days or so, and be on the lookout for power downs or reboots. After that, you can try adding a few apps at a time and keep checking. If the phone reboots even with a clean factory image, then I'd have to say the hardware is faulty. Could be the power button, could be something else.
Try it out and let us know
