Hi all,
Some months ago my screen cracked and last week I finally received a replacement screen which I was able to install.
I have been looking for many hours to find a similar case but could only find cases where the touchscreen didn't work at all or intermittently stopped working.
The problem:
I can start my phone, the touchscreen works perfectly.
When I lock the phone and seconds / minutes / hours after I wake it again, the touchscreen stopped working (the power button and volume button still work)
Repro:
1. I replaced the screen.
2. started the phone -> touchscreen is working 100% (i can do everything)
3. I lock/sleep the phone (power button)
4. I unlock/wake the phone (power button) -> touchscreen is not working anymore
5. I restart the phone by taking out the battery and we are back to step 2, it works but stops as soon as I lock it again
What I've tried:
- multiple different roms, all resulting in the same problem
- hard resets / factory resets/ cache resets / dalvik resets
- removing the slide lock
Is there anything I can still try?
Isn't it strange that the touchscreen does work after booting, but the moment it sleeps/locks it stops working
The only way it works is by never putting my phone to sleep, which is not the best solution, right!?
Unfortunately at the support center of the manufacturer they don't know the answer either:

I tried adding a link to a youtube video I made, but I'm unable to add it because of the no. of posts i have.
Does this video help explain the issue, and does anyone have any idea how I can fix this?

I have an SGH i780 and it has recently started freezing. Most frequently it happens as soon as the phone starts searching for a network connection. However, there are times when it allows me to make calls and once I hit the power button to turn off the screen and hit it again to power back on, it freezes again.
One thing that I have noticed is that right before it freezes, it does sort of a screen refresh (blinks) and then just hangs.
What I have done so far:
- tried different batteries - same issue
- flashed the phone - still same issue
- tried to hard reset both through windows and by pressing start+end call
buttons while powering up - still same issue
- opened the phone to check for loose connections/ dust - still same issue
Not sure if anyone here has had similar issues w/ this phone.
Any help / direction would be appreciated.
Thanks!

Yesterday morning after charging my phone, no different to anyother day attempted to type password in and nigh on impossible with curson blinking as if I was pressing enter - eventually managed to get in and it was if the trackball was stuck with the cursor moving down in every application making the phone nigh on impossible to use - reset a few times and took battery out and eventually (groan) went for hard reset but still happening - this is really bad and makes it impossible to use - help suggestions please
And threads just below this one another guy has the same problem on the same day it would seem - now that is weird / strange to say the least
I am in the procees of reinstalling the latest O2 XDA software update
16:50 installing latest update made no difference - problem still there
Is there a way you can disable the trackball - then at least can use stlyus / touch flo
OK - since the recent ota upgrade to ICS we've been having a few problems with the table touchscreen freezing - unfortunately now it seems to have got stuck almost all the time. Just at the moment, it is not responding at all to touch - just displays the lock screen when powered on, and then times out a little while later to black. I have to push power to get it back on - but the touch screen simply won't respond to unlock it. So far I have tried:
Holding down power until restarts - no effect - reboots still locked.
Using Vol-Down power on and doing factory reset - no effect - reboots into android setup screen touchscreen not working.
Draining power until it won't turn on. Then recharged. This worked! However...
After going through the setup process, resintalling apps etc., I hit the power button to go into standby. I then thought I'd go straight back in, but as soon as I hit the power button again, it wouldn't respond! Left it charging for a couple of hours, and turned on, this time got in - but same again - hitting the power button and coming straight back in, it's not responding again.
So I'm now back with a fully charged tablet that won't respond to touch at all. - perhaps if I leave it a few hours it might respond again - until it goes into standby!? The device is fully stock with WW_epad-9.2.1.11-20120221 (according to the screen at boot up when you hold down vol-d).
Is this likely to be software or hardware related? Do I need to send it for repair/replacement, or is there something else I can try first? Any help much appreciated. (Oh - I don't have external keyboard btw - so without screen it's pretty limited what i can do!)
Cheers,
Colin.
I have already encountered the same problem but with a cutom rom. to find my touch, I had to do a full wipe and new intallation.
I did full wipe using the Power/Vol-D but the touch screen didn't start working again until I let the battery completely drain.
Then I reinstalled everything (screen was working to begin with), however after I'd set everything up and reinstalled all my apps it stopped again.
Yesterday I managed to get an ota update to 9.2.1.17 (it started working for a short time). But then aftger rebooting again, it stopped again.
This morning it is working again, and I have uninstalled all my apps - just the core stuff on there now. For the moment it appears to be working (which is the longest for a while!) - going to see if it stops again while there aren't any extra apps installed...
Hey guys,
strange and frustrating problem. I was using my phone pretty extensively today (although nothing crazy), mostly thanks to Pokemon Go. Tonight after using my phone normally, I went to press the power button to turn the screen off and nothing happened. I was able to reboot (by changing one of the long-press actions to bring up the power menu via GravityBox) and then was unable to power on the phone. It seems like my hardware power button has suddenly become unresponsive. This leaves me unable to power on/off the phone, including booting into the bootloader. Also, I seem to be unable to wake my phone up by double tapping the screen or swiping up.
The phone otherwise functions fine. If I get a notification, the screen wakes up and I can use the phone. Otherwise, the only way I've been able to get into the phone is by connecting it to a computer and issuing ADB commands. The IR blaster functions fine which makes me think it's not the hardware button?
Has this happened to anyone else before? Can the power button just break like that without any water / physical damage? The fact that I also can't wake the screen makes me think it's a software issue. One other thing I suspect is that my phone abruptly died yesterday (battery died despite software thinking it still had juice left). In the past, with the modified kernel / rom, this has resulted in some nasty issues, including 4G not working and the Android system process basically exploding. I thought I lucked out when I powered it on after that, but maybe it just took a day for this issue to manifest itself.
I'm going to make a NANDROID backup and try flashing a few different things to see if I can fix it. I'll post my progress here.
Current build:
- Verizon M8, S-OFF
- TWRP
- Android GPE 6.0 (MRA58K.H13)
Edit: I haven't been able to find a fix. I'm a bit afraid to try a full RUU since I can't use the hardware keys to reboot into the bootloader should something go wrong. It may just be that my PWR hardware button is f'd which really sucks. I'm not sure I'm up to cracking open the phone to fix it. In the meantime I downloaded an app called Gravity Screen On/Off which uses the phone's proximity sensor to wake the screen up and it seems to work ok for now.
Hello everyone,
I have a Galaxy S7 G930U and it was out of warranty.
I searched the internet and I could see that so many people have had the same issue, not only the S7 but also other galaxy phones. I tried all the solutions available on the internet but still couldn't solve the problem
I was exposed to a light rain (I didn't have to use an umbrella) while it was in my pocket
1/ Opening the camera app, the phone, the camera app fails -> the phone freezes and reboots immediately -> after the reboot, the OS loads the camera in the background (I don't touch anything and let it boot up normally itself) -> the phone freezes again and reboot -> it booploops for several times until it's usable again
2/ what I have tried:
- Clearing the caches of gallery, camera app, clearing the Cache partition and factory reset in recovery mode, forced reboot by Vol -down + Power, booting in safe mode -> all of them couldn't fix the problem or just the phone was partially usable for a while until it happened again
- Navigated to Developer options -> Inactive apps -> inactivate the camera -> sometimes it worked but sometimes it didn't. I mean it prevented the bootloop unless I opened the camera again
- factory reset in recovery mode: it even bootlooped during the initial setup wizard -> it took me 6-7 times to finish the wizard due to the reboot during selecting the options
- Hard reboot by Vol-down + power -> sometimes, it was fixed but now this doesn't work anymore
- I took out the sim and SDcard tray and left it open for exactly 2 days. No improvement
- I tried to use my phone without the SDcard, nothing changed
- I left the default mode of the camera app in the rear camera and sometimes the camera worked. As soon as I switched to the front camera, it failed
- I tried to press the areas around the camera, tap continuously, shake the phone. Nothing happened
- checked for updates but no update was available
- I also noticed while I was entering the recovery mode, it said: "No command" (never happened before). It let it run for 30 seconds without touching, it successfully booted up to the recovery. This has happened all the time since then
bootloops
My current workaround to stop the bootloop is to clear the camera app data and never turn it on + inactivate the camera in developer options
Please help!!! This issue is very severe and makes me angry. I wonder why I bought this phone in the first place with this kind of issue. It's no longer a normal phone anymore
Thank you
If the rain caused the problem you could try using Isopropyl alcohol to clean the water residue off the board which could be causing the problem

hello, thank you for your answer, unfortunately, I'm not able to open up the phone myself, none of my friends can also do that. when I bring it to a phone repair shop or samsung, they may refuse to do what you suggest and recommend a full mainboard replacement. This may cost more than the phone itself. I'm don't really know what to do now
