Touch Screen stopped working.

Hey all First post, w00t.
New to the PDA type phone thing and learning what i can from here. Dont quite understand WM5 yet but i'll get it eventually.
nice fourm you all have here
A few post have hit the nail on the head with issues with the phone.
No hinge LED's when the phone rings is my main hate at the mo i think.
Also anyone know how to get media player to play videos in full screen? all it does is puts a black border round the video rather than streching it. This would be cool
Whats the differance between the o2 (or different) and corporate install type?
Also TomTom M5.2 is coming up all green lines, had a quick search and cant find a fix. Anyone?
Thought i'd drop on and say i've had a problem with my screen (gotta love us being beta testers ehh?) Only got the phone at chrimbo and woke up the other morning to find that the screen wouldnt tap. It seems that the screen is now tapping itself randomly, closing applications and not letting me use the touch screen at all. You cant reallign the screen.
Seems a few people have had this problem and it seems un-fixable, soft, hard resets and reinstalling the ROM doesnt work. pulling the battery out and leaving it for a short while seems to cure the problem for a short while.
If you're having this problem, call the retailer and have it replaced. Defo seems to be a hardware issue, maybe a bad batch?
I'm waiting on them getting a new one in store for me.

The screen issue does seem similar to the problem I was having.
Was on and off, but totally stopped responding early Sunday morning. Didn't start working again after numerous resets. Took it to the O2 shop today and it decided to start working again...
But they believed me, gave me a replacement and I've had zero problems with this one.
Seems like there may be some faulty ones about. Get it changed and hope they don't give you another faulty one

v1605 touchscreen issue & vodafones service

When it's cold it usually works.
but after a while it just works less and less until finally it's not working @ all.
I've returned it twice now. They just send it back after having supposedly replaced the screen. But i have my doubts.
Now I'm going to have to return it for a 3rd time. I have more than one of these phones and I do love them. This one however is just crap.
Apparently vodafone hasn't got a clue. Maybe I can give them some instructions on what to do with the damn thing. What would you tell them in my place?
I've had the thing for a few months now but it hasn't worked properly @ all during this period.
I even created a lovely video to show vodafone my problem

First welcome to XDA-Dev
You don't know it b ut the problem has been reported here umpteen times. If you use the Search Google Sticky post near the top of the messages postings you will usually find what you are looking for.
There are recent threads on this probably not more than one page back!
Regarding the servicing. Actually I can believe they have replaced the screen. BUT we here probably know more than they on some matters. We know that this problem is not caused by a faulty screen - it is not the more traditional Screen Alignment problem (though it is related to it). We also know that to test this after any servicing is done, you need to leave the device on using power hungry apps to warm the device up.
I always recommend anyone with a warranty to insist on a Replacement and NOT a repair for this problem. There is an interesting recent thread taht suggest slackening casing screws and even internal screws can alleviate the pressure causing the problem. BUT if you have a warranty get another device - new screens are NOT the answer.
Here as a welcome is a saved version of my search. Please use an existing thread if you wish to post on this matter.

Flaky Touchscreen (Just mine?)

I'm wondering if other users have experienced this. I find that after spending some time with the Transformer 300, especially when moving the machine on and off the keyboard dock, the screen will start to act flaky. In some cases what I'm seeing are "phantom touches." The home screens will start wobbling back and forth, as if someone is half-swiping them. In one case, I was playing the game "Sentinel 3" and the screen started zooming in and out as if someone were pinching it. That's with the tablet undocked. With the tablet docked, sometimes what I'll find is that the screen will become un-responsive. I'll click areas like the app drawer ad nothing will happen.
This is all resolved by shutting the machine down and bringing it back up again. This has happened to me numerous times, enough, in fact that I'm pretty convinced I'll have to take it back to Best Buy. My only question at this point is whether to return or exchange.
The fact that shutting it down fixes the issues suggests to me that it's a software glitch, which could potentially be fixed with a future patch. But that also means that exchanging the device likely won't do me any good.
So I'm posting this to get some feedback from the community and see if others are experiencing these same issues. If not, then maybe I got flaky hardware (a loose connector or something).

I agree it sounds like software since the reboot fixes it but your issue doesn't seem that common. I've seen a couple now that are somewhat similar but not like the pervasive left screen glitch. I would try an exchange personally.

Well sorry to burst the bubble but doing a reboot to resolve the problem doesn't really rule out a hardware issue. A hardware issue can be intermittent, there's nothing that states that it must be permanent. Furthermore it might not be the rebooting that resolves it but the time that passes. In other words, the problem might occur only at 6:45PM and last for 30 seconds, if you reboot it you might not experience it again. You have no time machine so there's no way for you to really figure out when it will occur and for how long to find out what's causing it.
It's all tricky. Some errors can occur both due to software and hardware so it's hard to determine which is actually causing it for a specific issue.
But a few things lead me to believe it's hardware.
1. Why aren't more people experiencing it? A software issue results in far greater people experiencing it, especially for a group as homogenous as TF300T owners who all own the same device. The conditions are already ripe and unless a third party app is causing it, everyone is running the same code and therefore more likely to experience the problem. A hardware fault would have to be deeply ingrained into the construction, the likelihood they had let it progress that far is unlikely. Instead, it seems like a QC issue which only affects a few individuals like you.
2. Touch screen issues have been noticed in not just this device but others. It can take on the habit of registering ghost input, no input, etcetera. Happens on the Nook Color too. Happens when the device is unplugged but mostly when it is plugged in to a power source especially the wall mains. If you're not getting it from your wall mains, it's probably the device. If it is your wall mains there's nothing you can do about it.
3. There's nothing random about handling touch screen events so I find it hard to believe this is caused by software. It's more likely it's a bad touch screen feeding false events to good touch event code. The likelihood code is doing this and doing this where only you experience it and not many others (actually I've seen no other people complain about this for the TF300T and two other people complain about it for the TF101) is really low.
IMO: Just exchange it. If you make the mistake of never exchanging it you'll be stuck on that boat forever. It's probably poor QC. If the second one has the issue, that bumps up the likelihood it's a software issue as these issues in hardware are very rare and I don't think two possible units experiencing it is very common unless it was a far more common software issue. If it occurred again I would either exchange it again or get a refund.

So yesterday I flexed the screen (basically pushed up ay the back, center with my fingers and down at thes sides with my thumbs) and the tablet started bounging between the home screen and the app tray at regular, 1/2 second intervals. back and forth, back and forth.
I also discovered that if I hold the tablet in portrait mode with my left thumb about 1/3 of the way up and sqeeze, the screen becomes completely un-responsive. if I ease up the pressure, it registers touches. I discovered this by readong a post by another user that had the issue (though I think in his case his screen would go haywire).
So I'm definitely taking this back to the store. The only question is whether its an exchange or a refund. I absolutely love the concept of this tagblet, and when it works its glorious. So if I can find one that doesn't suffer from these issues I'd love to hold on to it.

Check the running apps it's most likely mem related
Hi,
I've had two of these for about a week now, one for my self, and one for my 10 year old. I had to go into settings and shut off all kinds of stuff that was attempting to auto updated right off the bat. These don't come with a ton of memory right out of the box.
If you press on the bottom left corner of your screen the two little squares, it will show you what is loaded in memory. Every thing that comes up on that list on the left hand side is a opened application that is actively eating up your memory.
The only way to clear these apps once opened is to power the unit off, and then back on.
On both mine and my sons, I shut off all the auto updates, there are a bunch of different settings, you really need to go through them and look too many to list but a bunch should be turned off.
I don't have any issues at this point, neither does my 10 year old, he's always playing games like Fruit Ninja and normally has three or 4 youtube windows in the back going with in 5 minutes of turning the thing on and no issues.
Mine I use more for business related stuff, and also no issues. However right out of the box the first day it was a bit flaky. They both run smooth now.
I'm just waiting on some one to give me a root app for .26 since the second I turned these both on they updated the OTA firmware which took them off .17
Anyway I hope this helps.
Good luck.

Sorry didn't see the post about issues with where you pressed the screen. That one sounds like you may need to take it back in to have serviced. I tried what you said with squeezing the screen, and pressing the back in different spots. Nope, no issues like that. I would say it requires service.

The button you refer to in the bottom left is the multi-tasking button. If you press it and swipe an app, it will be removed from that list. Android usually runs fine with lots of apps sitting in ram. The only real exception to this is apps that are poorly coded and will try to run in the background all the time.
If you want root look in the development section, there is a simple utility to let you downgrade to .17, root, voodoo backup, update, and restore.

I have same/similar problem see other thread

See here for my symptoms.

So, last night I took the tablet back to Best Buy and exchanged it (actually, had to drive to a second Best Buy because the one where I bought mine was sold out!). So far so good. Though I've only had the replacement a short time, I'm feeling good about this one. No hiccups so far. And upon running the initial setup I remembered that even during the initial setup of my first one, the screen had become unresponsive once. All in all I've got a good feeling about this one. And I do desperately want it to work because, man, I love the concept and execution of this thing.

Have you tried the creaky test with the new one to see if it's a manufacturing issue indicative of all TF300T's or whether it was just an isolated QC incident?

Touchscreen Controlling Itself

I picked up my Nexus 7 about a half hour ago, woke it up and all of the sudden it started clicking things on its own. I wasn't even touching the screen at all. I had to lock the device for it to stop doing it, and after waking it back up the touchscreen was twonky. I would touch, but it wouldn't register until like the 3rd click. I restarted the device and its fine again.
I have the screen separation issue, though its not bad and doesnt bother me so I havent considered sending it back. But now that it has a mind of its own, its kind of freaking me out. I am unable to replicate it so far and I can't find anybody on these forums who has the same problem. Any ideas what is going on?

So it's a hardware issue and I should get it replaced?

I had the same thing happen to me a couple weeks ago.
After waking it up from sleep it started touching itself.
I restarted the device and it hasn't happened since.
Hope I don't have to return it.

My god! IT'S ALIVE!

I had the same thing happen on Saturday. There were odd solid white line outlines around the icons as well. I had to force it to power off and restart it. It's been okay since.

I too experienced the issue. I can replicate the issue by running "Gallery" app, select an album, set it on Slide Show mode. Within 15 mins or so, it will start malfunctioning.

I've discovered how to reproduce the problem on my tablet:
1. Put the tablet to sleep by closing smart cover or using a magnet
2. Plug in wall charger
3. Open the smart cover and the touchscreen malfunctions
The screen does not malfunction when I put the device to sleep by pressing the power button and insert the charger.
Can anyone else confirm this happens to them or is it just me?

My nexus7 is controlling itself after 10 mins of playing a game... this is nuts?
EDIT:
Really PI$$ED off now. Travelled to the shop where I bought it. Told them they said "they have to see the problem" I sit there for 25 minutes playing a game, google earth...anything to create this problem.
NOTHING.
get back home!! gusss what? stupid tablet is controlling itself again! OMG this crap is annoying.
edit: I sold the nexus. It had a fault on the screen. I paid £70 and managed to get £80 for it so am happy with that at least

Same issue!! Is someone remotely hacking in??
I have seen the exact same issue on mine. Weird and very worrying. Have seen apps being opened and pages being scrolled. Has only happened twice in the past few weeks (that I have noticed). Have checked firewall logs on my home network, but unfortunately my ISP has made the UI more 'user friendly' even in advance mode so can't get any actually useful information from the logs (though I don't have any port forwarding active). My only guess is that it is therefore:
A) Random HW/SW issue - seems unlikely, but possible I guess
B) Some nefarious app giving external access (all apps from Play Store though)
Will try and get a video of it next time to put on Youtube nad have installed the logcat app (though to be honest I don't really know how to use it).
Anyone else seen this or have any suggestions on what to do?

May I ask. Have you used a case that has a magnet that may have touched the screen? I theorized that this may have happened to mine because right where the magnet clipped the case is right where fault started. When i touched the screen just on the edge in that spot it started going crazy.
So I sold as faulty

Hi - I have briefly (only use it when travelling and have it in a bag to protect it from knocks and scrapes), but the case was never around when the screen has been off doing it's own thing....so I would be surprised if there was a link between a small magnet being near it a few times and a recurrent fault of some kind.

I read somebody else used a case with a magnet and thought that slight chance that it could've caused the fault. I know on the one I had I could instantly recreate the problem by touching in that place a few times. perhaps just a coincidence?

My device has a similar issue randomly. Detects inputs that aren't there. Most of the time it is one prolonged input. Sleep then wake and problem solved. I don't know if I have the screen seperation issue or not. My device is only two weeks old and has never seen a magnet before.

Bought 4 Nexus 7's for the family for Christmas and one unit had this issue. Read up about it before returning it the next day. Apparently it's a problem with the digitizer (I think that was what the hardware piece was called). Basically made the N7 unusable because it'd detect other "ghost" touches. Especially annoying when trying to unlock the device. Long story short, the unit was returned to Staples and replaced with a new one. So if you're is still under the "new buy" warranty I'd definitely try for a replacement.

Ditto, + 1 here and my ex-N7 16GB WiFi unit was from local Staples, 1 of 2 "open-box" ones that they had in stock, no wonder manager was "kind" enough to approve a 10% discount for it, hmmm - SOB quite possibly knew it was a problem unit returned by another customer & just wanted to pass it on. It had 4.1.2 loaded and intially, the OTA upgrade to 4.2 seemed to make things better (false.)
It was horrible with the sluggish & un-responsive touchscreen and even unlocking, especially bad over time as I had managed to unlock the bootloader & root it to load custom Rom. It's as if the hardware had a keylogger installed and/or was hacked remotely, trying to take over the tablet and typing its own command as I input gmail account info & password - freaking mad crazy, to the point as others said, I started checking the wireless router's firewall & security logs, etc. for signs of breach, etc. and even release the DHCP to get a new external IP on our Fios link. Disabling WiFi seemed to at least "calm" it down but made the device useless. GPS radio/receiver also seemed to be defective. To make a long story short, it has been returned to Staple as we are within the holidays/14 days technology product return & exchange timeframe - and, of course, all 16GB WiFi models are out of stock everywhere - ended up paying the difference & traded up to a 32GB WiFi model - S/N beginning with "CAO"s and has 4.1.2 on it
Noticed the immediate difference - this one is perfect and no hardware issues whatsoever - and so far so good and with all the issues cited about 4.2 - staying with 4.1.2 for now by disabling the fraemwork, etc. to stop the annoying OTA upgrade reminder. Unlocked & rooted, tweaked it with the goodies & Flash Player 11.x loaded with Chrome browser removed, this is what a N7 should be like.

I have had a similar issue twice. I was reading a webpage when all of a sudden a pop up appears asking where I want to send it to, then it gives me a list eg. Dropbox , email, etc. I never press anything and I didn't even know what wanted to be sent lol. Hopefully its nothing serious.

i have the same problem,had my nexus since nov 2012 just started to do this mind of its own thing 1 week ago at any time for no reason any ideas anyone?????

mine does it to all the time especially if i slightly squeeze the bezel? i get random touches all over the screen?

DVP11 - Any ideas what's going on with this screen?

I know the odds of anyone even seeing this thread are probably slim, but oh well, worth a shot I guess. We got this DVP 11 (5130 model) a few months ago from a customer who needed a password removed and wanted to upgrade to Win10. No problem (well, one problem, but I'll deal with that later...)
Anyway, about a week later the customer brought it back, saying that "the screen's all white." He said he didn't know exactly *what* all he'd done to it, but that there was a better-than-likely chance that he had screwed something up by either dicking around with settings, or possibly by damaging something when he decided to open the tablet up and poke around inside for god knows what reason. Anyway, you can see the result in the pics below. My initial thought was simply that he'd damaged the video cable, as I'd seen a similar sort of thing before where that was the culprit, but it looks fine and a new replacement cable didn't solve the problem either. Anyway, it got sat aside and the guy never came back to claim it. I forgot we even had it until stumbling across it again the other night, but alas, I'm still stumped. I certainly don't *think* this is a software-related issue - HDMI output is fine - but I guess weirder things have happened. Is there some kind of backlight controller that's gone out? I can't seem to find any other examples of this problem, so it seems like a freak occurrence if so. Another unusual thing is that the "white" effect kinda lessens the longer it's on, as you can see in the pics - almost reminds me of an old CRT TV that needed to "warm up" first. (The pics make it look less noticeable than it actually is though - it never entirely goes away and is still more of a visual hinderance than it appears to be. The last pics were taken approx. 2-3 hours after the first ones.)
Any ideas what's going on?
