Unresponsive touch screen :(

The top part of my phone does not respond to touch anymore... it is impossible to bring down the notification bar... and once in a while the whole screen goes unresponsive.. tried factory reset but still the same problem..

am having the same problem since 2 days back
after reading some of the posts i found that the Digitizer For HTC G6 Legend A6363 should be replaced with new one i ordered mine from ebay
ebay.com/sch/i.html?_from=R40&_trksid=p5039.m570.l1313&_nkw=Digitizer+For+HTC+G6+Legend+A6363&_sacat=See-All-Categories
waiting for the item to be delivered

I've also got a touchscreen issue: the area of the notification power widgets is unresponsive... the rest of the screen works fine, but I don't know for how long :/

Do you have widgetlocker, by any chance ?
Or a lockscreen replacement which disable the notification bar during the "slide to unlock" state ?

I didn't know there was such thing as widgetlocker. I use CM7 latest nightly, never seen that thing.

I also facing this problem from last 2 weeks and i also think this is digitizer problem. If anyone else found the solution else changing the digitizer, then please post.
This is beautiful phone but htc added a poor quality things in it, due to which many users facing such problems.

Nah.. I dont think its because of widget locker.. its the digitizer..

well that's a shame, gotta buy a new digitizer on ebay after just over 1 year of use...

I know.. this sucks... Im planning to upgrade though.. Any of u guys have any suggestion?

Depends on your carrier if you want suggestions for an upgrade.
...but that would drive the post off-topic.

I have the same problem. my screen doesnt work anymore because some water got in from the grill above the screen :S
should I try to take apart and dry off or shall I buy a new digitizer directly?

I think it may be a good idea to try disconnecting your digitizer and reconnect it as it just might be helping. I did it on my girlfriends legend and it has been working perfectly ever since. Maybe a good idea to at least try that before buying a new one. So i guess it could be in the connector to? At least this worked for me.

My touch screen dosent work at times. but after rebooting the phone the problem becomes solved. But the problem comes again after a week or so. Any suggestions guys??

I also have this problem, but if I wait a couple of minutes the touchscreen
becomes responsive again. Half of the screen works when it's unresponsive (right half of the notification bar and down). It's quite annoying but I cannot afford a new phone at the moment.
I'm also wondering if this might be temperature related, this problem reoccurred very often during the summer but stopped during the winter. But now (spring) it's back again.

My problem got worse and the phone became totally unresponsive, changed it, got a new phone.

exact same problem here, mine works when it feels like working, totally random, I simply can't understand why, I doubt it's the temperature... I think its in the device theres something wrong, I smack it numerous time and it works right after a big smack on the screen, or rub your whole hands on the screen, also, the angle you are holding the phone affects this problem, if none of these work, a phone restart always makes it work at the beginning. Oh boy did my phone took and taking much beating... oh well, I wish I could permanatly fixed the problem here, as I was thinking of handing the phone to my brother when I upgrade, I'm using CM 6.1.

I still recommend the same thing that i posted earlier here, her screen still works perfect.

I had the same problem few months ago. The problem is with the touch digitizer. I bought a digitizer on ebay and replaced it myself. After that my phone has been working fine. Its not that hard to replace it if you have a small knowledge about hardware.

I use to get that unresponsive screen issue only in the summertime, plus it gets worse if I add humidity (read: sweat). I just need to give it some time then to dry off/ cool down outside my pocket, and it's all fine again.

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?

it's another ghost unit...

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.

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

unresponsive touchscreen?

My nexus 7 currently has an unresponsive touchscreen. Almost none of my touches are working now and yesterday the tablet was working just fine but some of the touches were not working. Now almost all the touches arent working, did the hardware just fail on me?

Here is what I posted yesterday on another thread, but short answer is that yes it's most probably hardware fault (I don't have picture at work, so can't attach it here).
I purchased my Nexus 7 from Staples during business trip to San Francisco. My device started having touch screen issues after few hours. Factory reset did fix it and I liked the device a lot so I didn't return it as I thought touch screen issue was just a SW glitch. Issue came back at the airport . Unfortunately I didn't have time to return the device at that point. Issue wasn't manifesting itself all the time, but seemed to come up every time I plugged the device in charger. Symptoms were exactly as in this video: http://www.youtube.com/watch?v=uVkvCXDKU2M and the other one in which multitouch is demonstrated. I suspected different applications as a reason to the problem as well as faulty charger. Then I found this thread and became assured that this must be a HW problem.
As I'm living in Finland and don't know when my next business trip to USA will take place I decided to try and fix the problem myself. I took off the back cover and touch screen worked perfectly. Initially I suspected grounding problem but pretty soon came to conclusion that it can not be the case. The problem in my case was the "sponge" pushing (what I assume is) display / touch flex. I have marked that in the attached picture. Even a very light touch to sponge caused touch screen to go crazy. As I don't have the luxury of immediate warranty repair I decided to remove the sponge and my Nexus 7 has been working flawlessly ever since. I can even charge and everything works as expected. When I started charging the device I placed my Nexus 7 on the table. It probably caused slightly increased pressure on back cover and therefore to "sponge". After removing the sponge I can't see any of the touch screen problems I was having. Couldn't be happier as I don't have any of the other problems people have found and device is working as it should, at least for now.
I don't encourage anyone to do what I did, but if you are in the same situation as I was with imported device, you can try to take off back cover and see if the problems are fixed. You should be very careful though not to break the device especially when it's powered on with back cover off. Hope this helps someone.
EDIT: 22.8.2012. Forgot to mention, that turn of WiFi if using device with back cover off. Turning off NFC and GPS won't hurt, although GPS is receiving only. Reason is that antennas are located on back cover.

[Q] Nexus 4 Touchscreen goes crazy.

Hello.
​Firstly I would like to say that I am well aware, that there have been threads regarding this problem, however, none of them were of any help. Did not help on solving the problem or even determining the cause. So here is the deal.
​My nexus 4 is nearly 2 years old. It has had some tumbles, one of them was in January and caused my screen to crack. The touchscreen was unresponsive, but picture was showing just fine. I figured that I would change the screen and digitizer all together. And that is what I did, and it worked beautifully. I was quite happy to have my phone back, and it was working like this for nearly four weeks now with NO problems, what so ever. This evening has been a bit different. My touchscreen has been going crazy. Sometimes it recognizes the touch, sometimes it doesn't, sometimes it registers the touch in a different area and the phone just goes to **** all together. The phone hasn't suffered any damage lately, no falls or anything. As You can see in the screenshots, the screen appears to have a dead zone, right in the middle. Also, the phone lags quite badly, when the touches go crazy.
​Any help would be greatly appreciated, I would really like to avoid spending any more money (that i do not have) on spare parts, if the phone is unusable anyway. Some of the things I tried, that were suggested as possible solutions :
Factory Reset (both from booted phone and recovery mode) And the touch problems got even worse after that.
Clearing the cache (recovery mode as well)
Opening up the phone and checking the connections (which seem to be fine, since)
Hopefully You guys can help me find a solution, that wouldn't require me any more spare parts, cause getting stuff from ebay is not easy in my country. And I cannot even dream about a new phone, firstly cause I do not have any money, secondly - I love my nexus4, I am very used to it. It'd be a shame to let my friend gather dust on a shelf.
EDIT - At some point, the dead zone was non existent, as You can see in one of the screenshots I uploaded. The phone was opened up at the time, the dead zone was gone, but it was back after some lag.

Phone went nuts! Only long-pressing touches on my G2!

For a few weeks my G2 was showing some very weird touchscreen issues, like ghost touches and dead spots where touching wouldn't do any good. Although the former problem seems to have been gone, the latter looks kinda permanent. But yesterday another problem showed up: my cellphone will only recognize touches if I long-press the screen for like three seconds. Eventually if I'm typing some password the touchscreen will work as well as ever but only for a short time, then I'll have to press the screen for three seconds for every touch I want to be registered by the device. Anyone has had this before or heard about this? Is there a fix? I looked at lots of threads before and none of them seemed to sympathize with my issues.

It looks hardware failure. My advise would be try and go into service menu and then settings and update touch firmware. You never know it might work

That was my first bet. It didn't help much.

I had the same problem and it comes back with random conditions. I had the digitizer replaced (not the complete LCD panel) which had my problem fixed for almost six seven months until the problem showed up again but the dead zone moved Much lower than before. I have not gone for LCD replacement because i don't know if it will fix my problem. There are numerous threads here. Go try them Maybe they will work out for you.
