If you are rooted.
Try flashing a new rom or else, flash you rom once again.
When, rooted after you change anyther in /system, even a factory reset would not help.

sounds more like digitzer. You can buy the parts on ebay and there is a very good youtube video to follow. I replaced the LCD on my G2 and it took 1.5hrs (youtube video was ~30min).

Thanks bradley_e_smith, and when i was reading the email about your comment all 4 buttons started working and i installed "LockScreen Free" so all the important apps could be on lock screen for easy access and after installing and setting up lock screen button was dead again
so for time being till i replace digitizer all good

Screen problems

im running 2.2.1
the screen gets a little crazy ex in the browser sometimes it will only be in pinch to zoom when i only have one finger on the screen and it also the touch buttons stop working the only way to fix it is to lock and unlock any solution to this it is really annoying!
Mine also acts weird.. but not sure about browser. Have experienced it while playing games like Angry Birds. It keeps zooming in & out for whatever action u do while playing ABirds. Does not happen everytime...
I have the same problem begins two weeks ago but now the broblem there is at any operation of my phone, for example when i am writing a message the screen write characters, or automaticaly press the selections in the last line of the screen, i have eclair and cannot use my phone, i go to service on monday.
it is so annoying any fix?

I went to motorola service center yesterday and they change the touch screen and i get it back tommorow morning. Up to now all is ok!
ive heard it was a software issue
I have the same problem and it seems to get more and more annoying... The problem appears now and then and it disappears after I push the power button 2 times (turn screen off and on).
I'm waiting for an official Froyo to send the phone to service.
have you tried wiping cache, wiping data, and reflashing the sbf?
M having the same problem! TRied REstore 2 times din works i'm probably gonna un root n take it to moto!
If any1 got the fix then plzz post!

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.

Touchscreen problems

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] HTC desire 816 touch problems..

Hello guyz.. My htc 816 touch screen not working properly, have to press several times each button.. This suddenly happened.. I turn on in settings "show touches" and began to see in the left down corner on the back button that the touch is moving there and pressing back very fast.. Now this issue often appear .. But now the soft keys are not pressing from the first time I touch them.. The notification bar is to hard to open either.. And tapping a message is a massacre hehe..
P.s : I'm rooted.. And I try to install cm12 but nothing happened.
Plz friends help.. And thanks
Flash a RUU, or restore a stock backup and see if the problem persists.
I have the same issue. 816x single SIM. Any Rom I flash I get this same issue after a few minutes into the Rom. Only on stock it works normally. I have used most recent released of twrp and cwm. I have also tried garak kernal and stock trying to narrow it down. Any ideas on this?

R u sure is the same issue?? Cuz I'm worry it's a hardware issue..
Sounds the same to me. Have to hit home keys few times to get it to work, trying to text is hectic. During swiping it'll select things instead of swipe. Put on pointer location youll see it on and off while moving around the screen (even though you're doing a circle with your finger). Something around those lines?
Did anyone find a fix on this at all? Seen a few posts on this but no answers yet.
I have the same issue . plz help
same here. on virgin mobile, is there any fix?

I also have this problem. Just started two days ago. The most problematic is the going back button and the home button. Text is a nightmare as swipe works intermittently and it's all so slow. I've had to turn it off and on to get out of the camera or off another page due to the back button not working. It has also started bringing up random pages that I haven't touched, as someone else said somewhere.
I've taken the sim card out but that doesn't seem to be the problem.
So, if I restore to factory settings as has been suggested, what happens to my apps? I'm only concerned about my one paid app as it was $28! Can I just download via pc as I did initially?
What if this doesn't work? This is a new phone from January ... I love it :crying:

Your device software is not up to date speaking bootloader wise. This happens and causes your device touch functions to act up. This was an early issue when device was just released.

D855: Top of touch screen not working

Hi,
Since I flashed my LG G3 with LG flash tool, the top touch screen area doesn't work, making me unable to use the notification area.
I tried with a touch screen test application and about half centimer is not working in the top.
Somebody already encounter this?
Hey, you mean a part of screen is simply dead? I've had a very similar problem, only with my phone it was the middle of the screen, like on the video i recorded - https://www.youtube.com/watch?v=q_R1aGVUWhs
If your phone is on warranty, send it for repair, because it's probably faulty digitizer. If not - there are 2 options. 1 - pay for the repair of the damaged digitizer (or it could be simply not well connected, but you won't be able to tell yourself because the lcd and digitizer are not separetable, at least in theory, because it is possible, but highly unsafe). The other option is what I decided to do - you need to get a lighter with a one click button and do the same as this guy does - https://www.youtube.com/watch?v=VERfODYHX3g. It worked for me, at least it works temporary, but I heard if you do it a couple of times it will work permanently
Thanks guy!!!
