I'm having a weird issue on my completely stock, S-ON, non-rooted M7. Each time I reboot the phone, I'm unable to get it to sleep, either by the screen timeout or the power button. The screen simply will not turn off. Eventually it'll start working again after some random time period or random event, but it could be hours. If I keep rebooting it, it may eventually work after a random number of reboots. Once it starts working again, it's fine until the next reboot. Any diagnosis ideas?
Double check it isn't an app preventing sleep. Check all recently installed apps and their permissions (the one you are looking for would be "prevents device from sleeping" or something of that nature). If it isn't an app, it could be something corrupt in the data partition, which means only a factory reset would fix your issue. (Reboot to bootloader via vol down and power and select factory reset and press power button to confirm).

I'd factory reset

Old thread, but just wanted to close the loop to help others if they experience this. Turns out I would see this problem only when restarting the M7 WITHOUT powering down. If I power down first, then power up, the issue goes away. Strange, but at least it's fixable.

MY galaxy s2 has problems with powering off every now and then. it was really bad at one point where all it was doing is turning on and rebooting right after. i had a custom rom for months and never had problems until yesterday. i couldnt go on recovery mode because it would always restart every five seconds. Now it seems to less frequent because i realized that it always reboots when i touch the power button once. Sometimes when i push the power button to take it off sleep mode, the power options pops up (recovery, restart, power off etc) so thats when i thought the power button might be the problem
Any guesses on what could be the problem?? If its software problems or power button issue.
P.S. reset my phone, re rooted it, and put a new rom darkside. It literally stays on until i push the power button. then it restarts five seconds later.
the power buttons seems to stick....I have the same problem, the phone is acting as if the power button is being pressed without being let go. When the power button is held indefinitely it just keeps rebooting over and over again. It occurs sporadically, but once it sticks..it sticks. I seem to be able to unstick it by slapping it against my hand but eventually it turns off. Its definitely a hardware issue and I will open up the phone right now to investigate. Ill write if I find anything useful.

Hi guys.
So i managed to get my desire wet/damp and whilst it still works it has developed 3 issues:
1) The weirdest of all - the phone wont go into standby, as soon as you press the power button or let it timeout the screen goes off and they instantly turns back on to the lock screen. If i leave it, it will timeout again on lockscreen and come back on, it does this forever. I have done factory resets etc, all the same. Weird right
2) Volume keys do not work - think means i had issues getting into recovery. Finally found a widget to do it and then....
3) Trackpad does not work in recovery so i cannot re-flash or try any new rom to see if that fixed (1)
Proper catch 22
Any suggestions appreciated.
Thanks
Brisgstfer
UPDATE
OK I HAVE AN UPDATE:
The plot thickens but i have managed to S-OFF my Desire and eventually install Clockworkmod Touch which obviously doesn't require me to use the trackpad button so I was able to use Recovery. I wiped the phone and tried reflashing the ROM i had been using (Insertcoin) but this made no difference, the phone still keeps waking up immediately that it goes to sleep (either with power button or by sleeping timeout).
So i decided to install a completely different ROM (CM10_VJ_4.1.2_v3.0) and this installed fine. Now the phone will go to sleep and stay asleep if I press the power button. Problem solved I thought!
Now when the phone is asleep 50% of the time, trying to wake it with the power button will cause it to reset immediately and goto the white HTC screen. When it restarted it sits on the unlock screen and keeps timing out, screen goes off, then immediately on again - weird. If i unlock and lock with power button it will behave. For some reason the Search key will wake the phone every time no issues. Only the power key to unlock causes it to reset. Phone is sleeping according to Battery info.
Any other suggestions for what I could try. Could this possibly be something hardware related now? If there a way i can log the key presses or reason it wakes/resets?
Any help really appreciated, the phone is pretty unusable with this reset issue now.
THanks

May be a hardware issue. But try installing a lighter ROM like dGB or MildWild and see if the issue persists.

Thanks mate. So i tried this and installed CM7 today and have discovered something. As i said above the volume down button doesn't work and the volume up only works with some persuasion. Once i installed CM7 the problem where I lock phone with power key and it instantly wakes up now persists (on the JB rom it at least stayed asleep but reset if power button was pressed again).
However whe i changed the display timeout to 15seconds i watched as it timed out and instantly woke then noticed the volume would increment down one notch each it woke up again. This leads me to think that rather then the volume down not working at all it is actually stuck down permanently and could be causing the issue here. Is there any way I can find out if this is the case and disable the volume keys through software or do i need to open up the phone and disconnect it?
Thanks for any help - i think we are getting there!

Flash a ROM which can be unlocked via trackpad and volume can be adjusted from the phone settings without touching volume keys and the power button on the top.
I recommend MildWild5.8 based on CM7. When I was on it, I totally forgot about volume and power keys because all the phone operations can be done without them.
Thanks thats a great suggestion. I actually worked out that the trackpad is being pressed down constantly too because on CM7 when i disable trackpad to wake the phone actually stays asleep.
Is there any way to disable both volume and trackpad buttons at the kernal/system level?
If I long press the power button, instead of showing the menu where I have the commands like "Power off, reboot, profile, airplane mode" nothing happens and the phone locks just like if I pressed the power button once. And if I long press it for a long time the phone will force shut down which is normal.
However when I reboot my phone, everything works fine again, so when I hold the power button for 2 seconds, the menu appears. But after some time the bug will occur again and I will have to reboot which is very annoying.
Is there a fix for it? And do you think it is a hardware problem but it would be strange since after a reboot it will work.
Note : I recently factory reset my phone, wiped everything and flashed the CM 10.1.3 custom rom (which I also had before) but the power button bug reappeared. So I don't think resetting it again will fix it.
Using lg nitro hd, cm 10.1.3 rom, with wind kernel.
I just got exacly same thing, 10.1.3, wind kernel, and reboot will fix it.
Suspect is some memory leak? Logcat showed ION_IOC_ALLOC out of memory.

Ok, logcat is showing mpdecision missing timer something and throw error every 5 sec, then i figured out wind kernel 2.6 doesnt touch it, only 2.5 disable it. So i flashed 2.5 then 2.6. Now the logcat is better, but not sure this repeating error cause the oom, time will see

The model of my phone is SGH-T999. It is not rooted (I'm going to root it soon though), its running Android 4.3 and I do admit I've dropped it a few times but it has a cover. It shuts off at the most random moment and restarts itself, and sometimes it won't go past the Galaxy SIII logo before restarting itself once more. Theres a possibility the lock button has something to do because when it stays in that startup loop I play around with the lock button till it finally finishes the startup succesfully, but I don't know how the lock button can make it shut down on its own while its turned on without me touching the "power off" option in the window that comes up.
Let's assume for a minute that the Power Button is not the culprit of the reboot. Its certainly possible that the button causes reboots during Boot. Several people have discovered, this button can get stuck.
So given that, let examine your Reboot. You may have to try a factory reset to see if that helps. Typically if there are a lot of background apps running, the phone may get warm and reboot.
Speaking of temperature, you may want to use some Battery Temp monitor like TempMonitor. Stock firmware tends to have low tolerance for temperature and may force Reboot.
Holdin the power button will force a hard reset btw. So if itz sticking that'll do it.

The problem:
A few days ago, my Moto G5S started rebooting whenever I turned on the camera. This happened both with the main Camera app and in apps that use the camera, like Google Translate or WhatsApp.
But the phone doesn't reboot completely; it shows the first screen with Motorola 'M' logo with 'Powered by Android' of the reboot sequence, and then starts the reboot again. And again, and again.
The first few times this happened, this re-reboot cycle stopped after about 10 minutes; the phone completed the reboot sequence with no input from my side and started working normally again. But the camera issue still persists, and when it reboots, the re-reboot cycle keeps going indefinitely, until I force interrupt it.
If I long press the power button in the middle of the reboot sequence, and then wait for a few minutes to turn on the phone, it usually starts up normally. Sometimes it goes into the re-reboot cycle, and then I have to power off, wait and try again.
The only guaranteed way to get it to restart it is to connect it to a charger or my PC, and then long press the power button to turn it off. If I then turn it on while it is plugged in, it starts up normally.
General observations, and what I tried:
- This is independent of battery life. It happens even when the phone is fully charged.
- It happens even when no other apps are running in the background.
- The phone isn't heating up.
- I removed all new apps. No difference.
- I did a factory reset. Still the same issue persists.
Any idea what could be causing this? The phone is in perfect working condition otherwise, and I don't want to have to get another phone because of this one deal-breaker, if it's something that can be resolved.
Any help would be appreciated.. Thanks in advance!
