My phone keeps waking the screen when it is being charged (the screen timeouts and turns off before being turned back on again after a few seconds, showing the lock screen), even after i switch back to the standard USB charging cable (charging directly to the microusb port). I have checked developer options and keep screen awake when charging is not ticked so that's not the problem. Turning off screen using power button brings up lockscreen.
Additionally, my phone is not able to be switched off. When i switch off, it will enter into a sort of bootloop where the phone will spontaneously turn itself on showing 'Sony' screen > black screen and it repeats this cycle. The phone can however be turned back on during this bootloop if i press and hold the power button while the screen is black.
Guys help me please
I think that your phone's power button is faulty, maybe stucked or something so I kept being pressed
No never

I have set "no lock screen" option, and it is annoying that every time I connect the power cable or disconnect the power cable, the screen turns on. Since I set the time out to 2 minutes, it stays turned on for 2 minutes if I don't manually turn off the screen.
Is there any way to prevent this behaviour?
No. The screen turns on because it displays the "Connected" message.
Why does it bother you if the screen turns on? It will turn off automatically after 2min, once the cable is connected...
You bought the tablet to use it, not to keep it closed.
Hello!
I have a strange problem. My phone is constantly turning on (with elephone logo changing colors), then it turns on, homescreen appears and then after few seconds it just start the turning on process again (or restarting, at this point I don't know anymore), and it repeats that until battery is dead or until I turn in off. I can't connect it to computer because it's constantly up and down. V+ and power button is not working.
I've just dropped my RN4 and the screen stopped to work (black screen with no backlight) but I could tell that the touch was working well as I've managed to pick up a call. I wanted to remove the SIM card from the tray so I turned the device off by pressing power button for approx. 15s. Then I wanted to back my data up and boot the device to transfer data to the PC however I was unable to - when I've tried to press the power button to turn it on, device vibrated once and is doing so repeatedly from then on (the cycle is: vibration - 10 s pause - vibration-.... you get it). After plugging it into PC it is discovered as unknown device only. Is it matter of broken screen only or some more serious problem?
Good evening folks,
I am in need of help. I've been having issues with my tab S3 (SM-T820) for the last month or so. I notice that when i let the device charging over night, after i disconnect it, the screen goes black. I know the device is on, since the button lights are active. I've performed forced reboots (holding power + volume down buttons), and screen remains black, but device is on. I've performed hard resets via the odin software and the firmware, and yet the screen remains black (again, device on, button lights on). If i connect the device to a charger, when the screen is black, the screen turns starts displaying a black "speckled" display (black screen with color dots everywhere). When i see that, i start pressing the power button, turning the screen on and off continuously, until i finally get the screen to appear. Problem is that once i turn off the screen (not the device), again the screen will go to black and not appear anymore, until i keep messing with the power button again. I'm finally at lost since i sent the device to squaretrade for warranty support, and they keep sending it back as repaired (all they did was a factory reset, which is what i have done via the Odin software). Any idea on what to try next? I have though about disassembling the device and verifying the display cable is correct, but just seems irrelevant that it could be a hardware issue since eventually the screen does come on again (after trying countless of times), plus, i don't know how to disassemble this thing. Any ideas or recommendations?
Thank you in advance
my phone is rooted with Z2-lockeddualrecovery2.8.26
but today it start to turn off after each call
when i get home trying to turn it on it won't start, tried flashtool but no respond when i connect the phone while down volume key is pressed.

i disconnect the charger try to open nothing
then connect the charger again it shows 25% and i leave it for few seconds then it shows 100% but when i try to press the power button it shows empty charging battery icon while the phone is still off

Sorry for delay, as you said, It's faulty battery.
