Samsung M30 display not turning off - Samsung Galaxy M30 Questions & Answers

Hi,
I have been having this problem since last couple weeks.
If i turn off the display, it keeps turning back on.
No matter what i do, it comes back on after a second and stays on.
This is causing the phone to really heat up and discharges the battery in 2-3 hours.
Has anyone faced this problem?
Please advise on what i can do to fix the issue.
I have tried factory resetting multiple times, but still the issue persists.
Please advise.
Thanks in Advance.

Check your AOD (Always On Display). That is what is causing it.

[Q] Turns off after making picture

Hi,
Since a week or so, Im experiencing a weird problem with my Desire HD.
This is not always happening, but it happens very sometimes.
When I make a picture, the flash flashes, and the phone turns off... and it will not turn on by pushing the on/off button.
Only taking out the battery, and put it back in helps to get the phone starting up again.
After it is started up, the automatic blacklight adjusting is turned off, and the screen is on full brightness.
Does anyone else experience this problem either? and maybe having a solution?
Btw, it's not the SD, it also happens with a different SD.
Thanks in advance!
Greetz,
Joshoon.
Bump,
No one having an idea?
I only remember it happening the first day I bought it. Almost took it back for replacment, but then I solved it by removing the battery .
It never happened since, and the only thing I did after that was install the latest HTC update.
Check if you're updated.
I've experienced something close to this, only that my phone didn't shut down but just the camera app was closing anytime I tried to take a picture or record a video. Restarted the phone and everything works ok ever since.

My DHD was up-to-date when it happend.
It happend 2 times now.
I contacted HTC about it, there were not known with the problem, and the employee told me it could be a software problem, so they told me to do a factory reset.
Just did that, I hope the issue doesn't pop up again.
I'll keep the thread updated
Update!
Still had not the issue again, so HTC were probably right!
I still have that problem with shutting down phone after taking pictures with flash. I think it's battery related because it happens then battery is lower than 50%. All updates installed and I've done factory reset a couple of times. Anybody find a solution for this annoying problem?

I'm now switched to Galaxy Note since December, but it did not happen again with my Desire HD.
I also had a custom ROM on my Desire HD mostly after this all.
So you could try that too.
if your DHD turn off after take picture with flash, just replace battery will fix this, i'm tested with my DHD at 12/22/2013

Z1 Compact with Cyanogenmod - Screen doesn't wake

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

Wi-Fi turns on then back off

Hello! So this issue started about 2 weeks ago for me. Whenever I turn my wifi off, the phone will turn the wifi back on for 0.5-1.0 seconds then it will turn it back off. This happens nonstop. The issue persisted even when the phone was in safe mode and still continues even after 3 full factory data resets and wiping the cache partition 3 times as well. I did this through recovery mode. Nothing changed. When this is happening, it seems to drain my battery significantly. The only fix I have found for it has been to leave my wifi on all the time, even when I am not connected to or near a wifi hotspot. The issue also does not happen when the phone is in airplane mode. Also, I did not receive any software updates around the time this issue started happening. I have tried Googling and contacting Samsung and could not come up with a fix.
Is anyone else having or had this issue? If so, did you find any fix? Thanks!
If this thread needs to be moved to the help/troubleshooting section, please tell me how to do that, or do that yourself if you would like mods. This is my first time starting a thread so I am sorry if I put it in the wrong place.
Possible Fix
My Note 7 and S7 Edge were doing the same. I fixed it by disabling "Wifi scanning even while Wifi is turned off" in location settings.

Random and untimely reboots

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?

Display blanking

Hi guys,
I have a problem with my OP5t. Whenever there is a high load on the CPU, the screen turns off and on again, it stays off for about a third of a second and on for the same amount of time before turning back off. I had this problem on stock OxygenOs, also after a factory reset and I now have it on LineageOs 18.1, so I guess it is a hardware problem. Any guesses on what might be causing the problem? Sending it in to Oneplus for a service isnt really an option as it would be more economicalto buy a new phone. The problem occurs on battery and also while the phone is plugged in.
If someone has schematics for this phone it would be really helpful as well. Thanks for your help.
