Touchscreen problems - Nexus 7 (2013) Q&A

So I am having this problem since 4.4.3 and 4.4.4 update. Once or twice a day the screen won't respond to touch. Should I use a custom kernal or this might be a hardware problems.

How do you fix it when it happens? Do you have to restart? Does the touch fail or does the tablet freeze?
Honestly not very sure what you could do, besides maybe trying a factory reset? That would work if a software problem.
What about cleaning it and removing any screen plastic guard.

U can say it freezes then I have to restart it. This is happening after two factory resets.

Same issue here, I think.
Just purchased a refurbished Nexus 7 (official factory refurbished) from Amazon. My touch screen works great for a day or so, but eventually touch stops working altogether and sometimes requires a hard-reboot (holding the power for 10-seconds). Downloaded a touch screen test app which works great (even with ten fingers on the screen), tracking well on all parts of the screen. It's just like the touch atrophies over time until it stops working.
First thing I did to the tablet after getting it was to unlock the bootloader and load stock/rooted 4.4.4. Is there some way to update the touchscreen firmware that I'm missing?
I don't want to open this thing up and muck with the hardware for fear of damaging it. I'm holding out hope that there is a software fix, because rebooting fixes it right up.

Oops - I looked at the link to the hardware fix, but not the firmware fix. Thanks, I'll give this a try first.

Firmware fix above seems to have alleviated the issue for me. At least I haven't seen the issue over the last several days, which is good news. Hopefully that holds up over the long term. :good:

[Q] different volume bug, same thing or broken phone

have i got the volume bug if my phone hangs and then reboots every time i touch volume up or down when the screen is on? Samsung insist that its the same thing and i need to wait for the update but i can't see anyone else describing that the problem causes a reboot, and my volume has never actually turned down on it's own as far as i can tell.
That sounds different altogether.

Thats what i suspect. Its just a pain to have been waiting for 4 days for something that probably wont fix anything and then to have to start the whole thing over again with samsung. O well

Deal with the retailer you bought the phone from, and get a replacement from them.

I'll give it a go. Im guessing they wont do a doorstep swap like i'd get from t mobile though. Hopefully i wont be without it for long. In our short time together i've grown quite attached to this phone (and almost got used to not touching the volume button)
Couple of questions (you may have already done these -apologies if you have)
Have you tried a factory reset? If not, maybe worth trying it, could be an app doing wierd things.
Also, try running a logcat trace when replicating the issue - see if it helps point in the direction of the issue.
Does the phone still crash when you're in the bootloader? (This _may_ help to rule out application related issues)
I have tried a factory reset. Weird thing is that im pretty sure that it didnt do it for the first few hours that i was playing with it. It was just at the point that i had it all set up that i first noticed it so assumed it was a rouge app and did a factory reset. When it rebooted i signed in and hit volume and it crashed so its definately not an app.
I almost believed that it was the normal volume bug because if i go somewhere more remote in the house, away from all electrical stuff, i can hammer at the buttons for a while before it crashes so maybe ive just got a more extreme version of the bug. Just noone else seems to have anything close. Volume control works fine in a call and when the screen is off but i havent tried in bootloader yet. I'll give it a go

[Q] Problem with ROM Jedi Mind Trick V9 Please Help!

Hi everyone, I am new here but not new to rooting phones. I've followed the instructions for installing |ROM| Jedi Mind Trick |V9| 9|19 completely and thoroughly and I've waited the 10 mins (sometimes more) before I rebooted the phone. Every time after the reboot, I start messing with the phone and checking out the features, my capacitive buttons just completely stop working, they are unresponsive and they don't even light up. Also, the lockscreen doesn't work unless I press the power button once and then I can go into the phone and everything else is working except for the capacitive buttons. So that leaves me stuck in the last app that I was in and I cannot go back home since the capacitive buttons are functioning.
I have tried reflashing the ROM 3 times and the same exact thing happened each time. I also tried rebooting the phone and turning the phone completely off and the capacitive buttons will function only for about a minute and then completely stop working again. I was wondering if someone knows how to fix this or if anyone was experiencing the same issue and found a way to fix it. Please let me know, I'm not sure what I did wrong for this happen since the ROM seems to be working for everyone else.
I found I had far less problems and quirks after installing teamwin touch recovery. Then flash.

I747m screen problem...please help!

Ive searched everywhere and can't seem to find anyone with a solution. Ive found a post with the same problem but no solution.
So yesterday my s3 started having problems waking up. Meaning when I lock it usually you bring up the lock screen by pressing the power button or home button. Problem is when I press either one, screen doesnt come on. The buttons do. If I tap the screen I can hear the ripple effect but the screen doesnt light up. I have to keep locking and unlocking till it finally works. Averege of about 6 tries. When I get a call most of the time the screen doesnt come on either. I can still answer since I know where the slider is. When I do turn it on everything works perfect. No flickering or any other issues. When it boots it works perfect...never fails. Just when I lock it.
I tried restoring already, thinking its a software issue...still does it. What piece of hardware could cause this? I'm stumped. Please any advice would be great.
I'm not rooted and running 4.1.1 oem rogers software.

My guess is that you have something draining all your RAM or being hard on your CPU. When you restored, did you factory reset?
You might have to backup your stuff, factory reset. Test it, if it still does it, bring it up with Rogers for a replacement. If it doesn't, reinstall your stuff until you find the culprit.
You could troubleshoot it also by uninstalling the latest apps you installed.

Like I said...Already did a factory reset. Meaning All apps were gone. Started fresh. Even without going through the first setup (setting up google account etc etc) if I lock the phone its hard to wakeup.
Phone is out of warranty so no go there....
I'm just not understanding what is causing it. I know the screen is fine...buttons are fine...everything points at a software problem. I found a post from a while back where someone was having the same problem....no solution was posted though. I even took the phone apart last night thinking a bad connection or something...disconnected the screen and reconnected it...didn't do anything.
If the screen was going bad wouldn't I have issues all the time? Once I wakeup the phone it works perfect...no flickering or anything. When it boots (which I've done like 30 times between today and yesterday) the screen has come on every single time perfectly fine. Everything tells me it's software related...but after doing a factory reset and running original firmware it seems as though it must be a hardware issue...but which component.
I know the phone wakes up when I press the buttons...I can see the menu and back buttons light up...and if I tap the screen the ripple sound is there...just the screen doesn't wake up....till I try a few more times....very frustrating.
Thanks Again for trying...if anyone has any ideas....greatly appreciated. I'll try and find original Rogers firmware and install with odin...see if that works....

Sounds indeed like software issue. I'm not so sure what would cause it on stock rogers though.
Either way, you can find the stock ROM on sammobile.com or on this thread: http://forum.xda-developers.com/showthread.php?t=1822308
You'll need Odin to flash it. (It doesn't trigger the flash counter)

Did you buy your phone with a credit card? Some cc's have warranty built in. Mine doubles what the manufacturer offers.
Thanks for the link. I will try it tonight and post the results. Really hoping it works.

I downloaded the newest firmware. 4.1.2 official rogers. Problem persists. Must be a hardware issue. Thing is what could cause this? Is it the screen...is it the gpu? I imagine if its gpu the phone is only good for parts as I imagine its part of the motherboard. Oh well...might be getting the s4 sooner then planned.

If you're down for a little test, you could try with a custom ROM.
Use the link I gave you and flash pre-rooted Rogers' ROM. From there, install TWRP (or cwm) using goomanager (from the Play Store) and flash a custom ROM as per their instructions (Don't forget the Gapps).
Before anything though, make a backup
Never know, might save you some time on that S4.

Thanks. I might try it. Dont think I have too much to lose at this point. I always try and keep my phones nice so that when I get a new one I can sell the old one for good money to help offset the cost. This really messes with that system as the phone isn't worth much now...just bought an extended battery too...was planning to keep it for at least another 6 months.
Sent from my SGH-I747M using xda app-developers app
So just a quick update. For no apparent reason the phone started working fine again. It now turns on and off just fine. I'm not going to mess around with it anymore. That's really bizzare. I'll give it a couple days and will report back if it continuous to work fine or if the problem comes back. Thanks for the input.

Xperia M touchscreen stops responding randomly

Hi, Im new to the forum but used roms for another device in the past.
I wasnt able to find information regarding to this trough days, my phone touchscreen stops working randomly on stock rom [15.1.c.1.17], have anyone had this problem? Is it sw or hw related?
Thanks, phone is awesome when the ts works but this is driving me crazy... thanks
If you haven't modify the software then it must be hardware related.
What modifications did you do? Did it have the problem from the start(when you bought it)?

If it doesn't happen under specific conditions (for instance, while playing the game, or during the call), it is most likely hardware related, my best bet is that screen digitizer is either faulty or not connected properly to the motherboard. Have you dropped/spilled something on your phone? If not, you should return your phone for a warranty repair.
Its randomly occuring, its fixed after reboot or it will work itself again after a while, sometimes a couple of minutes others a couple hours, phone is new, bough on jan 17. Havent dropped it or spilled anything on it... problem is I updated from stock rom from the provider to an official by sony and dont have a backup of it :/.
Update to the newest version ends in 2.8 that's the newest one see if that helps

[Q] Soft keys issue- anyone elses soft keys just stoppped working

Hello everyone. I am here seeking help for my Optimus G Pro. My soft keys are not working, they just stopped working today in the afternoon. It all started when i tried to download the leaked vitnamese kitkat version for my e980. At that moment i was running G2 v5.5. The download was taking forever it had onlyva speed of 100Kb but it wasn't constant. So imagine i kept checking the progress every 10 minutes.
During one of those times i noticed the some activity on the screen as if it were being pressed in multiple places. It seemed weird to me, i just proceeded to wipe the screen. The screen acter normal again and it stood still. My susrprise was when i accidentally went into the wrong app when i was trying to check 9gag and i pressed the back button and instead it opened the app in the lower left corner. I thought it was my mistake but it wasn't when i pressed it again it highlighted a section on the running app. I stood still and analyzed the buttons and neither the back or menu button worked. I have made factory resets even a hard reset with no reaults. I am now running Sphinx v1.3 but the issue persist.
I have thought that either the phone is damaged, the keys may have been unmapped due to some issue with the old rom , the phone needs a touch firmware update or wether i have to replace the touch sensor. Though the rest of the touch screen works great. Also let me mention that the phone has not been droppen in a long time.
Maybe i could flash somehow the touchscreen firmware and it could help? I dont know.
I need advices and criteria from the experienced ones.
Anyone else has experiences this or knows whats going on?
Thank you in advance to anybody who wills to help me. ???
I had the same problem. In my case it was the screen. Lucky I am still under warranty so LG fixed that.

Thank you for your reply...
So, you have an idea what caused the problem? And how it coukd be fixed?
My screen on the physical end seems great.
I have had mines ever since it cameout so i doubt i qualify for warranty.

Has it been a year? If it hasn't then you should be under warranty.
