I have a S9+ and the screen kerps reseting to 30 seconds.
I have all the same apps, nothing new there.
Solutions i read here havent fixed it. Im at a lost.
Can a theme do it? (Only new thing i did was change my theme)
Running android 9.0
Do you experience these symptoms if you test your device in safe mode?
It happens while i sleep at night from what it seems like.
I set it at 10min where its always been since the beginning and now for a few days when i get up in the morning its back at 30sec.
I dont turn off my phone.(once a week it restarts automatically but that has never affected it in the past). It happens every day.
I would have to leave my phone on safe mode during the night to try.
I would recommend trying your device in safe mode overnight. Please keep me posted if you are still experiencing these symptoms.
So the night of your last message (before yesterday) it didnt do it. I woke up and my phone was still at 10 min.
Last night it did it again.
Could a game be causing this issue? The day it didnt do it i didn't play a new game i downloaded and then yesterday i played a couple hours and turned it off at same time i went to bed and in the morning it had changed.
Will be testing safe mode tonight.(i do have a feeling it might not do it in safe mode. Im almost 100% sure it wont)
Check optimize settings in app power management. During what your phone thinks is inactive hours it optimizes certain settings to save battery, like reduce brightness and screen timeout
OMG i think i figured it out.
I found a kind of hidden setting similar to the note 9 settings.
According to what i saw that should be the cause.
I turned it off and well see.
Here are screenshots of the settings.
Steps i did (s9+ android 9):
-Click settings app
-Click on battery icon
-Click top right corner the 3 dots then click settings.
-Scroll down to optimize settings. (And turn that sucker off)
P.s: cannot change the 30sec option in optimize settings. Too bad i would've left it on if it weren't for it.
