Screen won't auto turn off. Any ideas? - OnePlus 6T Questions & Answers

Hi, I am running stock OOS and stock kernel. It has been few days since this is happening, I can't link it to any new app etc., but my screen won't turn off when I don't use the Oneplus 6T. After 30s (as per settings), the backlight/brightness turns off, but the screen itself is active, just very dimmed. I need to turn it off manually by power button every time I need my phone to sleep. I tried restarting several times, I have no idea why this keeps happening.
Any ideas?

Stupid question but did you check your screen time out settings?

OP says he restarted several times; presumably that means reboot.

I missed that.
The only other thing I can think of is wiping the cache.
If that doesn't work, then try safe mode to see if its an app doing strange stuff.

screen won't timeout

I have a i9020A and my screen will not time out. I have it set to 15 sec, even installed screebl and set it to 15 sec....no matter what i do the screen won't turn off unless i press the power button......tried multiple reboots and no fix....how do i fix this? this is becoming a real pain
Try doing a factory reset. I had the same problem. It was not the first factory reset that solved it but the second one. Make sure you do not install the apps immediately. After the facotory reset use it for a day or two and observe. Then install the apps one by one. I think some apps cause this problem.

Is the phone plugged in? There's an option to keep screen alive during charging which may be enabled?

Tablet keeps turning on after I turn it off?

Every time I turn off my tablet, the next time I go to use it, it's already on.
Anyone have any suggestions? Is this something that other people are experiencing?
Thanks!
Never experienced that
I don't know, My first N7 is faulty but not that bad, maybe your tablet is reading your mind and it turns on when your thinking about using it?
How are you turning it off? Tapping the power button only turns off display.

i am powering it down by holding power and pressing power off.

That's weird. Are you rooted? Running a rom? On stock? Some additional details would be helpful to solve your problem.

It's clearly haunted.
Or an app is waking it up to sync / find location / steal and transmit your data.
Have you tried running Avast ? Locking all the running apps ?

So how does the alarm clock work :laugh:
And he hasn't said he's shut it down, he said he's switched it off.

quite strange..
I don't believe apps can turn it on when it's off..so if you turn your N7 off, your alarm is disabled. at least, I'm pretty sure of that.
And, so you watch it turn off all the way? And later on it's on?
Is it plugged in to the charger?
Have you ever watched it for a little while [while you were doing something else, just glancing at it once in a while] to see if it just randomly turns on?

I'm pretty sure that I turn my N7 off at night and the alarm wakes me up in the morning.

really? but how does that work?
that means the clock app must be able to control the rtc hardware, and tell it to power up at a certain time... I didn't know they'd done that on the N7...

Calendar -> Settings -> General Settings -> uncheck Notifications
It's a shot in the dark but who knows..
Or I suppose if you like you could disable calendar sync in Accounts & Sync, and then erase Calendar's data.

[Q]Cannot lock screen automatically

My nexus4 cannot automatically lock the screen anymore, The setting is that it should turn off the screen after 1 minutes, but the screen just keep on light all the time, the only way is pressing the power button manually.
The ROM version is 4.2.1. Do anyone have the some issue? How to resolve it? Thanks a lot.
Mine locks after a given time. Try rebooting and report if it changed something maybe... Or try changing the screen off time (for ex. try 15 seconds).

Change given time does not work , after reboot it is OK, The question is it will not lock automatically after a few time use.
Really strange....
Is your phone rooted?

No, after deleted some apps, it works OK in the last two days. May have some relationship with the apps.
I will keep watching...

screen will not timeout.

I have screen inactive settings set to 15 seconds. But my screen will not turn off on its own no matter what. I've tried all inactive times and none work. If I get a text my screen turns on and stays on till I shut it off. This is killing my screen and battery. Anyone know if this is fixable? Should I try factory reset? Thanks
Just in case anyone has this issue I learned a temp fix. Backup and restore and then reset settings. But the issue just arised again today. So it's only temp.

If you have the Dev option on to 'Never Sleep' then that's why. Otherwise I have no idea.

Nope. it's super annoying. And restarting phone won't fix it. All I change is ring tone and text tone. Takes about 3 days to start acting up again and it really kills my battery with my phone on in my pocket.

You don't have a Pebble do you? I found a setting with YANC Pro that was keeping the screen on

[Solved] Screen won´t turn off - only dim down

Anyone else having a bug where the screen does'nt turn off after the designated time out is reached? I have set mine to 15 seconds but it only dims down after 7 seconds and remains dimmed forever and ever.
Only way to get phone to work normally is to restart it. But the bug keeps coming back every day, sometimes serveral times a day.
Now I have to turn off screen manually by pressing the powerbutton.
Update Solution:
I actually had locked(in recents) Edge browser into the memory so it always would be available lightning fast. I just unlocked and closed it from recents app, and now the screen shuts off normally. Apparantly there was probably a hidden ads-page active somewhere keeping the screen from shutting off properly.

Not much, only the Force all apps to be resize:able.
The screen awake while charging is off. USB-debbuging also.

I have encountered this bug occasionally, a few times this happened some web page was open (No video was playing) not sure if this was the case with you sometimes some ads or something on the web page can keep the browser active. I did not think much of it nor explored it much but will keep an eye out if it reoccurs.
Turn off Developer options for now.
Does it happen in Safe Mode?
Make sure a 3rd party app isn't the cause.
Clear system cache on the boot menu.

Big Thanks! I actually had locked Edge browser, Telegram and File Manager+ into the memory so they would never be killed off. I just unlocked and removed them all, and now the screen shuts off normally. What a relief [emoji846]!
Using Adguard adblock and Edge content blocker so it might have been a hidden ad of sorts keeping phone screen active.

Glad it worked, I suggest copy paste above text, what you observed the reason was for this to happen and what you did to fix it and add that information to the first post. Trust me it will help many.
Also change the title to: [Solved] - Screen won´t turn off - only dim down
