Hi,
I have:
Sony Xperia Z1 Compact
Rooted
CyanogenMod version 11-20141112-SNAPSHOT-M12-amami
Android version 4.4.4
Kernel version 3.4.0cyanogenmod-g1b20e398 [email protected] #1
Build number cm_amami-userdebug 4.4.4 KTU84Q a265284510 test-keys
My phone's screen has the annoying problem of sometimes not waking when I press the power button (while the phone is turned on). The phone is still on, but doesn't respond to input. I can call it, but nothing happens. I can connect the charger, but it doesn't respond.
I did not experience the issue before rooting. After rooting and installing CyanogenMod, the problem occurred perhaps 1-2 a week.
Recently I encrypted my phone. After that the problem has become much more frequent. The screen is now unwakable roughly 2-3 times a day, some times even more!
The only solution I have found, it to either turn the phone off via the red off button next to the SIM card, or by rebooting it by holding the power button in for so long.
The issue is extremely annoying, especially after it started occurring 2-3 times a day.
I have tried searching for similar issues, but haven't found any solutions.
I have tried changing the brightness levels so the max level is 99% instead of 100%, as someone had suggested, but that hasn't made any difference. Unscrewing the phone and cleaning the proximity sensor, as someone else had suggested, is something I haven't tried yet, as I don't feel competent enough to unscrew the phone.
The phone used to have the protection plastic provided from the fabric, but I tore that off not too long ago. No change in behaviour.
I have not managed to find one special event that triggers this behaviour or reproduce the issue on demand.
Hopefully someone will have some tips as to what I can do to solve this issue. Thanks in advance.
Any modifications on the kernel? Like special governors or under/overclocking?
As you are using a custom ROM the clear advise here is: try out with stock ROM and see if the problem is still there.
If not, it is a problem with the ROM.
I'm having the exact same problem. I flashed cm11 snapshot two days ago, and today my screen wouldn't wake no matter what.not even a restart would solve the issue, cause the moment the phone goes to sleep after a boot, that was the last time the screen was on. I'm following this thread in case somebody comes up with a solution.
hi there, my phone is acting the same way as yours described. Mine is rooted on stock lolipop and it never happened before although i had a replacement unit and the one before that acting the same way. Pressed the power button and nothing happend regardless screen on or off. Had to do hard reset and it worked for like 1 or 2 days. I went to sony talk forum and ppl seems to say it a bug since the phone released. If anyone got anything would be great help. Thanks
I've been having this problem since the other day. The day before that, the phone's just working perfectly fine, tho, when I woke up in the morning, the phone just suddenly got this screen glitch. It only seems to be having a glitch in dark backgrounds... But given some time, the glitch disappears, but then again, if I turn off the display and leave it some time, the problem reappears.
Please look at the vid.
I don't think it's a hardware problem since the splash image isn't affected and the glitch seems temporary, but changing ROMs doesn't help. I haven't tried the stock firmware tho. Gonna download the stock fw and try it and see if the problem still persist.
Hi,
It's a hardware issue.
It's not related to any ROM you're using.
I've same problem as you and I decided to return it to stock and sent it to the nearest Asus Service Center (in Makassar) via my local seller because there is no one here in my location.

its not hardware issue if that not happen when you use screen recorder.
give a try then...
@baonxxx
This isn't related to software. I had this screen glitch even on stock (applies to everything: Splashscreen, etc) and caused difficulties on normal usage.
By general you can trigger this screen glitch by let the phone heating for a period of time, like let the phone idle for hours, charging, or let the screen on around the time. *only on affected devices*
You may need to read OP once again.

as u can see in the video , it doesn't really affect the splash screen, tho if flashing back to the original fw doesn't help, then I may need to get it to Asus Service Center for them to check.

I know that, but when the screen glitch becomes worse, it would happen on everything.

hhmm, not really everything, only glitches on dark backgrounds... seems like the screen on my phone's having a problem on dark backgrounds.
it is definitely a HW issue. did your phone ever fell on the ground?
this usually happens when there is loose connection between the mainboard and the display.
if you haven't void the warranty, send it for repairs, otherwise open the phone and fix it yourself (just detach and properly reattach the display connector, and make sure it's grounded properly).
@pecholino
Only unlocking the bootloader with official method provided by Asus could void the warranty.

damn it's a HW issue and it's getting annoying... gonna send it back for repairs... damn I didn't even dropped the phone once, so much for ASUS.
It happens with me too. On stock firmware. But is very rare and temporary. Turning off the screen and then again waking up solves it.

it happens to me on stock as well. Same as yours turning off the screen and waking it up makes it normal. so it's not a firmware problem? or is it?

I don't think this is a hardware problem as so many people are having this problem.
This problem happened to me the next morning after I updated to 2.20.40.168 I didn't drop me phone in between the time I updated and the time I first seen it happen. I've already sent my phone in and Asus replaced my motherboard. I got it back and problem was still happening.
The problem may go away for you if you set Developer Options, Disable HW Overlays but the setting does not seem to persist after a reboot.
quick settings
I noticed another remarkable phenomenon. When I open the quick settings, the defect is gone. But I only can operate in the quick settings, nothing else.
The screen freezes until I open the quick settings. -
I have reinstalled all software, even the boot partition. The defect already occurs in the splashscreen and fastbootscreen. -
I have opened the plug connection to the screen and connected again. -
So far everything in vain. -
ASUS claims, it is a defect on the motherboard. - I am afraid they are right.
It is a hardware issue. The problem is with the screen, precisely, the multiplexer on the screen. But since it is a part of the LCD itself, you will have to get the entire display module replaced.
Replacement displays are available on eBay/Amazon and you can get instruction guides on YouTube.
If your phone type z00AD Try downgrade your rom only to 2.12.40.11.. its solved my problem..

I'm having the following issues with my OnePlus 3 (stock recovery, no root):
15 November: last known date without any issues
16-18 November: when I played games I noticed that screen won't rotate even when auto rotate was ON
19 November: I wanted to click some pictures when the camera app just stopped working
Tried rebooting and clearing cache, but didn't work
Thought a software update might fix these problems
20-27 November: when I answered calls the screen won't turn off. That's when I realized that all the sensors on the phone had stopped working (no lift up display, motion sensors,etc). Read online that I could get the official Oreo update just by changing my VPN to Germany/Canada. So I did the same and upgraded to Oreo
Still the issues were there and battery drain was significant. The phone would reboot on its own.
On contacting OnePlus support they asked me to do a hard reset which seemed to work only for 3-4 days
28-29 November: the sensors stopped working again & again and I did a hard reset every time
In the end the phone switched off and the white notification light was on continuously. Pressing or holding the power button didn't work. Contacted support
2 December: through a remote session the OnePlus support installed Oreo again and on rebooting I got DM-VERITY error. So the support asked me to visit a Service Centre
3 December: I visited the SC where they concluded it was a hardware issue (motherboard: 17000/-) so I asked them to just roll back to OOS 4.5.1. Worked fine for 10-11 days
14 December: started rebooting randomly. Noticed that the phone would hang and reboot when using the camera (in WhatsApp, CamScanner and stock camera), maybe I'm wrong.
So now there's minimal usage of a phone with such high capabilities knowing that I'll have to do a hard reset once a week.
How can it be a hardware issue if the phone works fine for 4-5 days after a hard reset before breaking down again? What does that white notification light mean? Any help would be greatly appreciated

There is your answer, there is a problem with you motherboard, you need to get it replaced, we cant diagnose a hardware problem here!
How come it works normally for a week or more if there's a problem with the motherboard?
And a hard reset seems to return the phone to its normal state.

That just means that it is faulty and will fail after some time. This most likely means there is a bad memory sector on the board. As suggested. Get it replaced or you will keep having these issues.
Okay. Thanks for clarifying.
May I know what may be the causes for the motherboard damage? How common is it that a motherboard malfunctions?
Because there was no physical damage at all. Thanks again!

See that is the thing. China has no real quality control standards. So it could just have been a bad board. If you look around you will see that a range of random issues seem to pop up over a short time. Yet some are just fine. Like mine. It had a faulty USB port from day one to the point that I knew it was gonna fail. (expected) So I am replacing it.
Hello everyon everyone.
I have the SM-P600 version, everything was good until the beginning of the week when touchpad began to go off without reason, and completely random.
I first reinstalled several official ROMs from the most recent to the oldest, with no significant improvement
Then i rooted and tried Lineage, it looked good for a while, but in the end same problem.
Please note, when the tablet begins to mess, the reboots are occuring more and more often and after a while it turns in a loop and im not even able to switch it off.
Samsung logo display, black screen, logo, black screen, etc ...
I think rather for a battery-side problem, if some people have faced similar problem, I'm taking help.
Do you know if by chance we can use the tablet without battery to test this theory?
Thank you in advance for any answers.

I think I'd be taking a close look at the physical power button. Seems to me that if it had gone flakey it could cause something like this.

Hello and thanks for you answer,
Just to precise i never faced this issue while flashing an official or custom ROM, dont know if it is just luck or it can help in anything
Anyway ill try to check it the power button just in case
It's weird I just started having this exact problem myself. One morning I unplugged it and it had shut itself down overnight. Since then it randomly reboots. Sometimes I can get 20/30 minutes out of it, but once it starts, it can get into multiple reboots with the only way to stop it is to plug in the charger. I tried wiping cashe/dalvic (no help). Nothing was recently changed (including apps). Tried resoldering battery connector (battery was replaced a year or so ago with OEM Sammy). The P600 is rooted with TWRP installed, but no custom ROM. Usually the reboots start while I'm doing something (surfing, email, etc.), but I don't think it will do it while sleeping. I'm considering the power button, but I don't see this exact problem anywhere else, but this post. Any ideas?
OK. My tablet has taken a turn for the worse. Now it is stuck in a continuous boot loop. I tried the power switch, no help. I tried booting into TWRP, and it went back into rebooting before I could do anything. Strange thing is I can put it into download mode indefinitely without it rebooting. Should I ODIN back to stock? I tried the resoldering of the battery connection earlier. Any other ideas?
Hi,
I'm wondering if there's anyone else who is facing this problem or I'm just unlucky.
On last Sunday, when I was listening to YouTube Music at a low battery (around 15%), after a while the phone shut itself off. I guess it was just the phone ran out of battery so I tried to charge it. But the moment I plugged in the charger, the hidden emergency flash light in the front turned on (the one on top right). When the phone successfully booted up, an application called CQATest appeared with a notification. The phone won't charge and take SIM card anymore since then.
I've done some research and tried many methods to fix it, including reboot in the recovery, factory reset, using adb to change boot mode, reflash the rom, disabling the CQATest app. None of them could solve my problem. Disabling the CQATest app does let me to have signal again, but I still cannot get the phone charge. It shows Turbo Power connected, but not charging.
Is there anybody facing the same issue, or even better, have a solution?
Thank you.
Update: I found a solution for this. I put my phone to fastboot mode and charge it from there, overnight. Next morning, it's working normal again.
You can always try a custom ROM. And make sure to format every partition in TWRP before - format, not just wipe.
If that works you can try other stuff. If not you have a hardware issue is guess and only a phone repair could fix that.
PS: try a different charger. If it's only not charging it might be an issue there. And have you tried to charge it while the device is shut down?

Thank you for your reply. Yes I did try another charger. However I'm using a Qualcomm qualified charger so I don't think that's an issue. I brought it to UbreakIfix and they told me it's a motherboard problem so the only way to fix it is to change the motherboard. It'll cost a phone to do that. I'm just wandering if there's any body else who is having the same issue. Because my problem appeared out of no where.
That's normal. Hardware problems often appear out of nowhere all the sudden. And it's always hard the really on them down to a source.
And yes, repairs for not typical phones are always expensive. On my first Z Play the screen cracked. Seeing the price of a repair and realising I could get an unused Z2 Play for the same money you can guess what I did. Can't say I regret it too much.
