[Q] Touch screen problems - Galaxy S II Q&A, Help & Troubleshooting

Something strange is happening last 3 weeks. Every time i turn off, than on my phone, touch is not working, all buttons are forking(including digitizer). When that happens, I need to turn it on and off again, and then it works
What that could be ? I tried flashing another roms, but problem is there again. I switch batteries a lot, and that is very annoying.

If you've experienced this on different roms, than it a hardware problem. I can only guess here but it could be a loose display connector or the display/digitizer showing it's age.
As far as I see - have three options here - get the phone repaired / get used to this glitch or get a new device.

Yes I also face this type of problem while playing games. Screen become unresponsive while playing but can solve by pressing power button(no need to reboot).Not on 2.3.5 base only on 2.3.6.
I also face this problem, after updating my rom to arctic 2.0 rom, which uses some stuff from 2.3.6.....power does not help, have to hard reboot. any idea why?
I've had this problem happen to me on my Droid RAZR (CDMA Verizon), can't remember if its before or after I was rooted... I just had to hard restart and its only happened once since then.

The power button does not work for me
I had try to press the power button, but then the screen still not responding, so I cannot pass through the lock screen, and have to hard reboot......
I am on stock rom, 2.3.5, the Asian version.
But it seems it does not matter to different region's razr since the cdma one had the same issue

I get this too. I had 3 razrs, first two had dead pixels so I had them replaced, all had this issue. Has not happened in awhile and I can't remember if it was always with a game, but at least one time it was with a game. Anyway, I don't think this has to do with rooting because my first one I never rooted and it did this. Don't remember if power button worked or not, but I had to reboot as well with power and volume down, or up, whatever it is, to get it to respond again.
No problems here.
I have had this happen about 4 or 5 times for me as well - got it day of launch. Mine says it is the XT912 though - is that right?
XT912 is the Verizon specific one, so yes.
Seems to be a fairly common issue. What is the chance that this is a software problem as opposed to a hardware one and so will be fixed with an update?
I had it happen for the first time yesterday after about 5 weeks or so, strange cause I wasn't doing anything. Battery was at about 15% though...
I only encounter this bug when I open Rom Toolbox for the first time and the superuser permissions screen shows up. My screen doesnt respond to touch anymore. I have to use the power button to make it work. Thats it. It happens nowhere else.
I've been using ROM Toolbox since day one, can't say it's the issue.

Happened to me today...any need to panic?? On official Stock ROM 2.3.5...
Also, is this a hardware issue or software??
My problem is bit different, on a 4 month old unrooted razr.
Touch screen will start to fail recognizing my sywpe typing and start jumping all over the place, or it will end the word while I'm still sywping the word...
Sometimes it types in different letters (1/2 keyboard away) when I'm not sywping to avoid this BS when it happens.
Unfortunately, I cannot reproduce this result whenever I want to, I'm currently trying to reproduce the situation.
I believe this happens more often when my battery is low... or when I have been using it for an extensive time.
I go to draw program to test if it is the hardware problem and it is jumpy too, but not by much.
The problem does get better with reboot, but not 100% of the time, so I can't conclude it is SW problem
I also have issues with this. I think the problem is software side. It seems to be poorly responsive often after I unlock my phone and try to swipe screens.
Also while typing quickly with two hands it often does not input all the letters I type, although it flashes the keys and acknowledges that I touched them (this one might be a keyboard issues, not sure yet)
And ya, on an all black screen, I'm noticing some dead pixels- a lot of rectangular patches of dead pixels. I don't really notice it anytime else except when it's all black.
Been making me double think my choice, but I will wait for ICS update and possibly bootloader bypass. But.. I might be getting another phone shortly just because of the size (bezel mostly), these touch screen issues, and the performance isn't exactly where I anticipated it to be.
Razr XT910 touchscreen randomly jumping or not responding
I'm having all the problems mentioned earlier:
- touchscreen stops working randomly
- touch "jumps", like someone is touching it in random places
- some letters on the keybord stop working randomly
- phone gets quite hot at the top
My XT910 is not altered in any way, stock android 2.3.5, as updated as possible.
This happened when it was up-to-date and the very clean one.
This happens really irregularily. At first it happened when I played multitouch games - at some point the touchscreen just stopped responding and could only go back or lock the screen (but not unlock it, obviously).
Twice it happened when I was just going through messages or contacts.
I sent it to Motorola to fix it - they just reset it, benchmarked it for 45seconds and sent it back.
The very evening I got it back I tried to "heat" it myself - I installed a lot of apps, played a lot multitouch games on 3d graphic and voila! - it started freaking out like never before (vidoe in zip file attached).
My last idea is that it happens because of a low quality generic anti-scratch foil on the screen. So I threw it away and tried to "heat" the phone again - nothing.
I used a different foil - anti-reflecting + benchmarking apps - nothing.
If it happens again I'll send it with this video + the one I'll make then.
Hope it gets Motorola specialists off their ass and back to work .
Hey there, my maxx has this weird issue with it's screen too.
Take for example, a game with on screen controller like reckless racing. If i push the screen too long, it won't recognize my press anymore in the pressed area. I tried to go back home, thinking this is the game issue, but it's not, the home launcher button that coincidentally in the same location with game control button is unclickable. i tried with phone tester app and it show the same symptom, the pressed area indicator will disappear within 1-2 minutes.
The only solution is to turn off display and turn it on again. Should i bring it to service center?

Hello, I've recently having this exact same problems with my Motorola Droid Razr Maxx.
The screen sometimes doesn't respond as it should:
-Random touches.
-Not detecting swipes.
-Not detecting anything at all after long press.
-Detecting the touch location wrongly...
When this happens, sometimes a reboot fixes everything. Others, I just have to stop using the phone, and come back later.
Has anyone managed to find a possible cause and/or solution to this problem?
I've tried diferent roms, full reset, rsd flashes... But still the same problem

From sleep to lockscreen LCD blank problem,any solution?

Hello.
When I leave my phone in sleep mode (screen locked and light off) and try to wake with On/Off button, sometimes I get a black screen with a faintly image. The touchscreen works and all the buttons, and if you click 2 times On/Off button - the image appears all ok. I tried to flash another stock ROM - all the same. Then I`ve unlocked the bootloader, rooted the phone and even did the S-off with wire trick (1.53 Hboot). Then I`ve tried 3-4 custom ROMs with 6-7 different kernels, from stock to custom, but all the same. Yes, I`ve updated the firmware file, also, but with no difference.
Well, I see that this problem is not so usual, but I couldn`t find any real solution. Did anyone have this kind of problem and solved it? Since I got this phone from another country - official warranty is out of the question, I need a DIY solution.
Any help is greatly appreciated.
THX in advance!!!
I would have to say it looks like the light for your screen is dying, I had my screen replaced once, my screen would flicker from very dark to very bright

hmmmm, but when I get the OK image - it doesn`t flicker or go from dark to bright, it only has trouble to "wake up from sleep mode". even when i relock the screen quickly and don`t leave it unused for 2-3 minutes, the screen works OK every time....it looks like a software problem, but still I didn`t manage to fix it with all the ROMs/kernels/firmwares I`ve flashed....

Thinking about how to troubleshoot if hardware or software. When in sleep mode, instead of using the power button, I would have the phone plugged into a computer and use the " adb reboot " command to reboot the phone without touching the phone a few times and see if it lights up correctly. The first thing you should see is the boot screen, and if it works every time, then you do have an issue with your firmware. If you don't see that boot screen first every time, then as much as it sucks, I would guess there is a hardware issue.
Good luck, but this is the easiest way I know of to help determine what the issue likely is.
Minor update here, the first thing (at least on mine) that I see is the lock screen for just a quick second or two, then it quickly goes into the boot sequence. This is important as in "sleep" the ROM is running, so if the first thing you see is the boot sequence every time, and not the lock screen, then it points more to a software problem than a hardware issue. CM9 had an issue for the epic4g where you had to turn it off and on sometimes to get the keyboard to light. They found the issue in the firmware causing it.
Just wanted to make this as accurate as possible.
Wow so I am not the only person with this problem. The EVO 3D that I have was replacement phone that was given to me from Sprint from the first EVO 3D that I had which had issues with the digitizer. I received the replacement phone this past Tuesday and it worked fine for two days. It was not rooted and I did install the ICS update. On Friday morning I took it off the charger and went to work, while in the break room the screen suddenly went black and I could not get the phone to display anything after that. The Android function buttons at the bottom will light up but the screen wont, the phone also gets hot even with it powered off.
Long story short, I took it back to the Sprint store where they ordered me yet another replacement EVO 3D. Has anyone had to go through 3 EVO 3Ds or more?

Excellent thinking, I didn't think in that direction. I'll try this tomorow, since I'm not at home. My personal oppinion that it's a software problem but if I did all the above - what did I miss? If I flashed the firmware, ROM and kernel, what else is left untouched that could affect the LCD? Could anyone suggest a good kernel? Or can I downgrade the firmware, since no one had such a problem with GB?
just to inform all - I tried all soft solutions, but all the samo. finaly - I replaced the LCD and everything is OK.
THX all for help

[Q] Touchscreen wakeup issue

Hi everybody,
Recently I've been encountering a problem where my streak won't respond to any touches after I open the screen. Pressing the power button and waking the phone up again does not solve the problem. I've read about the static issue, but unfortunately it doesn't seem to be the case here as the problem still occurs even when my streak isn't in my pocket.
Oddly enough, rebooting the phone solves the issue temporarily. The touchscreen will work perfectly until I turn the screen off again, but when I turn the screen back on, the phone doesn't seem to register any touches. The phone itself works fine as it still receives notifications even when the touchscreen is unresponsive.
Is this a hardware or a software issue?
I'm currently on DSC 2.2 and baseband 366. I'm going to try a factory reset right now to see if any will improve.
Thanks!
Edit: did a factory reset, problem is still occurring
I have the same problem, does anyone know how to fix this? thanks

Have you tried recalibrating your touch screen from the dell menu?
Its option 3, worked for me a few days ago.

Yeah I have. I'm currently assuming it's a hardware issue since I've reverted back to a stock rom along with several other custom roms but the touchscreen still remained unresponsive after waking it up. I'm hypothesizing its a bad connection somewhere, especially if the display and touch sensor wake up separately. Does anybody know anything about this and whether it can be repaired?
On the other hand, I might be completely wrong...
I noticed that some bags for DS5 produce static electricity, such as the original Dell Bag (Futon bag - ?)
The Leather Bag (with red fissure) does not produce static electricity even when having the DS5 in trousers.

I had this problem once, pried and screwed the Streak open, checked connection ribbons, and cleaned it with (a little bit) electric contact spray. This has saved my irresponsive power button as well! Success:good:

[Q] Another Digitizer Thread or Maybe Different One

Hi, I have a quick question.
My digitizer starts failing. I know in the end it should fails cause most of them need to be replaced but maybe my problem is different.
Most of digitizers are stop working at all or only some parts of it. My digitizer is working fine but ONLY after turning on screen sometimes it's working like using it with wet fingers - it's crazy pointing everything without my control. After turn off and on screen it's working fine until next turning on.
I'm wondering can it be software problem?? I had similar problem in Defy+, leds under hardware keys stop lighting and before sending it on warranty I wiped it and now all working fine.
It's no problem for me to replace digitizer or wipe system but it would be good to know that it can be software problem before buying new digitizer.
Maybe you need to apply the raindrop fix. Been discussed already.
First, thaks for understanding what I mean. (Very poor english)
Second, this is exactly what I ment. I just copied tounchpad.cfg from http://forum.xda-developers.com/showthread.php?t=1467696 and all looks fine now. No mess up on multitouch. I hope it will stop messed up touch while turning on screen, need to test it for a while cause this issue isn't appears on each turning on but ocassionaly.
Anyway thanks for fix. You saved my time (3 hours on wiping and bulding new system) and money on new digitizer.
One more thing. I'm using this phone from few months and everything was ok. The problem appears few weeks ago. So if it is bug in rom it should appears just after I bought it, not after few months. Or maybe it's not factory bug but just error in touchpad.cfg??
Sorry for post under post but I have few more informations.
After testing few days raindrop fix the problem still exist. Fix helped but not fixed problem. Still after turning on screen touch is acting crazy but after first touch it stops and before applying fix it stops only after turning off screen and turning it on.
I reflashed full sbf stock Gingerbread, full wipe including internal memory and still the same problem.
Strange thing I observed is the problem appear only when WiFi is on and it's searching or trying to connect. When WiFi is off or it's connected to router the problem never appears and when I turn on screen and after that turn on WiFi everything is ok. Only when I'm turning screen with WiFi on screen touch acting like crazy.
Is there any chance to fix it or should I buy new digitizer??
Ok, I changed digitizer on warranty and now everything is okay. Funny thing is that I have unlocked bootloader and they changed my digitizer without any problems. Less funny is that they broke both sensors changing it and I had to send My Atrix to Motorola once more after two days to change flex. But now I hope it should be working fine.
So after all it had to be popular hardware problem.
Thred can be closed.

Very strange crash every time I use my phone

I can leave my phone plugged in and charging and quickly check a text message and reply, and my phone will be fine. But if I try to use my phone any more than that, the display gets strange artifacts (it's different every time, ranging from a dark grid overlayed on top of the image to the screen filled with different colors on each pixel) and sometimes the speaker emits a constant loud high pitched noise, even if it's on silent. I noticed one of the times that the sleep button worked, but using the touch screen and the capacitive buttons is impossible and I have to yank out the battery every time it happens. I'm running a recent CM10.1 nightly and default kernel, and I've experienced this problem independent of which nightly or kernel I'm using for the past few weeks (I have had no problems in the recovery menu). It even crashed one time upon boot up when I tried to unlock the phone immediately. Another minor problem is that my home screens got screwed up one of the times it crashed. It seems like a hardware failure to me. I'm wondering if anyone has seen this problem or has any ideas that might help. Thanks.
It certainly sounds like a hardware issue to me. I have not seen anything similar reported on these forums. Is the phone currently stock, or custom firmware? The best test to see if the problem is firmware or hardware related is to flash a fresh stock firmware using Odin3. If the problem goes away, then it is obviously a firmware issue.
If it is a hardware problem, you may have trouble flashing a fresh stock firmware, or may not be able to at all. Or if you are able to flash a new stock firmware, but the problem does not go away, then it is probably hardware.
