N7105 - Has just started to reboot every time screen off - Galaxy Note II Q&A, Help & Troubleshooting

What the title says.
Without warning and without any modifications to my phone even remotely recently, tonight, my phone has decided to reboot every time the screen goes off. Actually, it's more like:
-screen goes off
-If I press a button to bring it back on, only the keys at the bottom get illuminated. if I'm lucky. Otherwise:
-reboots
I don't get it. I've tried two separate batteries, I've wiped the phone completely and reinstalled the rom I use (a CM11 one) but I'm at my wits end. Is there any way to troubleshoot this, or is it buggered?

[Q] Please help! Random power off won't boot!

Okay I will try to sum this up. My S3 was working fine and everything randomly I noticed issues with battery calibration It would be 100% then I would calibrate it and then unplug and then I'd instantly drop to 85%. Thought It was a battery issue and made a point to get a new one later. Then it kept working for another month or so then It started really screwing up the shutdown menu would randomly pop up and I'd back out of it.
Then randomly 3 seconds later the phone reboots. And it would keep doing that randomly I thought it might be a power button issue. Then as time goes on it got really bad to where it would simply reboot and not make it past the bootloader, It would not "reboot" more like a complete shutdown then I'd have to power it again and have it do the same thing. Seeing how I could not even make it past the bootloader I got a new battery, waited a week for it and then I put it in and the same issue happened. It would not get past the bootloader.
So I kept trying and trying and trying and it finally booted past that. And it stayed on for a whole night. I did everything on it I normally would and it was working great. Then the battery was getting low so I plug it in and was going to calibrate it after it was charged, I go back to it and it's dead again won't get past the bootloader once again. I'm completely out of ideas on how to fix this I pop'd off the button and blew in there and the button seems fine and everything still no change. I also can not get into recovery. It trys and loads but then shuts off. Anyway if anyone has any ideas on what this is or how to fix please help! I need my phone back! Thank you.
I'm running MOAR Lite version.
UPDATE: Took the phone apart and took a close look at the button it looks 100% fine...I saw a video on youtube that requires you to complete tear the button off and it works. But I don't know if the button is my main cause of this issue or if it will actually work. Some says it works, some says it does nothing...Please let me know thanks...
UPDATE 2: It will show that battery with spinning circle in it for like 1 second then turn off again. (When it is plugged in)
That's odd. But when it comes to the power button, dismantling and what not 90% of the time will show 0 issues. It will look perfectly fine when it's not. You playing with the power button I assume were pressing hard and normally to try testing it. It's a common issues on this version of the S3 to have faulty power button and you would need to get it repaired. Odly even slightly atmospheric changes can cause it to act different at different points. Some days it works fine, other days a very slight brushing over can cause it to screw up and trigger a manual shut down (holding for like 10 or 15 seconds).
Assuming that it is the power button, or to try, just do a variation of things to the power button itself. Use your finger nail to jiggle it around with different pressures. During boot if it shuts off, it could be the power button internally stuck, just jiggle it around.
This is all I can think of unless you bring it in to get repaired.
I was encountering the exact same problem. I would try to get into download mode and it would sit at the "Downloading" screen for about 5-7 seconds then the display would go blank. It won't make it into recovery either. Based on the above recommendation I took the whole phone apart and sprayed a lot of compressed air directly on the power button mechanism and the plastic case pressing the button in. I didn't see anything broken with the button when I did that.
It seems to be working now, I can boot into my Rom. Don't know how long this fix will last.

[Q] Bricked help/ideas

In short, the phone is stuck in a bootloop unlike any I've read about before. All on its own, it constantly makes the bootup vibration pattern but it does not boot up. The screen does not light up, it is completely black (backlight is off as well). It is sitting on my desk doing the vibrate patter (bzzz-bz). Then 40 seconds later, again, (bzzz-bz).
If I could see the screen, I imagine it is going past the 1st Asus Logo screen, then trying to load the OS (2nd Asus Logo), but crashing and restarting.
This happened after I flashed fastboot (droidboot), recovery, and boot. All flashed successfully, so I went into Recovery and started to "wipe cache". It was taking too long so I thought it froze and forced a restart. After that, I never saw the screen light up again.
Any ideas as to what is going on? The phone has no damage (at least physically ).
Yes, wiping cache takes a long time you have to wait it out, forcing reboot before it finishes will result in bootlooped, that is covered in many many threads, you will need to reflash entire Rom from bootloader.
Problem is, I cannot get into bootloader. Its still doing the vibrate cycle I described, it's been 8 hours already.
Try holding the power button and volume up toll you get 2 vibrates then release power, if that does not help it sounds like your power button is stuck in depressed mode
Stuck in depressed mode? But I am able to press it, and I hear it click, and click back up. The "spring" seems to be working fine.

G3 VS985 difficult to turn on, recovery mode buttons don't work

My VS985 has 2 problems, which may be related to each other. The first is that, when the phone is fully turned off, turning it back on again is difficult. When I press the power button, the phone just vibrates at me and then refuses to turn on. Screen doesn't light up or anything. Pressing the power button again does nothing at that point. What I have to do, sometimes up to 7-8 times before it turns on, is remove the battery, wait a few seconds, put it back in, then press the power button again. It'll vibrate every time, and eventually one of those times it will turn on and boot up.
The second issue is that I've found it impossible to get into recovery mode using the buttons. I can get in just fine using the quick boot app, but that's not much use if I ever end up in a state where I can't boot into the OS. Apparently it's supposed to work by turning the phone off, then pressing and holding the power + volume down buttons and waiting for the LG logo to show up. I've tried this many times, it never works, possibly because of the first problem.
I bought this phone used, immediately used ODIN to downgrade it to the original stock OS, then towel rooted it and installed CM (LOS 14.1 now), so I've no idea if this phone has always had this problem or if I caused it. It's not a big deal since I always keep my phone on but makes trying new ROMs scary. Has anyone heard of this before, or have any idea how to fix it?

Tab S4 WiFi - Screen not turning back on after timeout. Tablet still running.

Basically most of the post in the title.
I've been playing around, got it rooted with WETA, installed Kali, went back to Stock. In both Kali and now Stock, if the screen times out, or if I hit the power button to lock the screen, it will not come back up and only a hard reboot will get it back.
Same here. I’m rooted but stock rom. Been rooted for a while but this problem only started within last few days. Same exact issue. Booted into safe mode and problem still exists: if screen gets turned off or times out, can not get it to turn back on without hard reset.
I just factory reset mine. I use it for work so I wanted to see if I could reset and restore. During the setup process when it asked for the wifi password I went to the other office to get it and by the time I came back, the screen had timed out and would not come back on still. So, tells me it is not an app and is likely a hardware issue.
Edit: Well, now it seems to be working. I let it sit and restore for a while. Tried to turn the screen on and it took a bit longer than normal but it came on. So far it does not turn the screen on with a screen tap like it used to but it will turn on with a little delay after pressing the power button...
Update on my update: Tablet still has times where pushing the power button or tapping the screen does not turn it on. I basically have to make the motions as if I am opening the magnet case up and the screen will turn on. So, not all the way fixed...

P600 Black screen, but android still runs(?)

Okay, so here's the issue:
My P600 starts normally, but I end up with a black screen (not the regular one caused by the LCD cable being loose). Not really sure when it started, parents say it's been like this for a day now. All I see is:
-The top bar (with time, audio/vibrate setting, Wi-FI signal and battery)
-The drop down menu
-I can start S voice
-I can see all the apps I launch by pressing the icon in the drop down menu (by holding the middle button, as you normally do)
The screen reacts fully, I can roll up the drop down menu and shut down the apps by moving my finger across the screen.
It throws out the "Process system isn't responding" error every once in a while.
The lock screen flashes through very briefly when I go back from the "all launched apps" menu (not really sure how to call it).
Steps I tried:
Restart
Wipe cache partition
Connecting to a PC doesn't do anything
System(Android) is fully stock, and was probably updated (not sure what was the last update Samsung put out).
Factory reset(or flashing a new android) is the last thing I want to try, thanks.
