Screen flashing when phone is on charge/not charging - Huawei Mate 20 Pro Questions & Answers

This is driving me mad at night.
I press the power button to turn screen off. I also have phone set to sleep after two minutes. It stays off for approx two minutes, then the screen flashes on and stays on about 8 seconds, then screen goes off for two mins, and on, and repeat, all day and all bloody night long.
This happens whether the phone is on charge or not. Bluetooth off, just either wifi or data on.
I have it set to always on display so I have the clock on screen when off, I have tried turning this off but it still happens, any ideas?
I really REALLY do not want to wipe and start again.

SORTED. I had "allow notifications to turn screen on" turned on. Disabled that, and now no more flashing.

Screen quickly turns off

For some reason my screen quickly turns itself off when I awake it from stand by. It's like 3 or 4 seconds and then the screen will turn off, I can normally get around it by quickly pressing a button and this will keep the screen on.
It's also not a constant problem, after a soft reset the problem seems to go away for a random period of time and then return.
Any one else experience similar?

Just go to Sound and Display --> Backlight --> Set it for longer.

That doesn't work mainly cause there isn't an option to turn the backlight off after 3 seconds
sorry, wrong tab selected
pls delete.

Atrix Screen wake up issue

Suddenly, my phone screen just turns on for 2 seconds, then goes back to sleep
for no apparent reason, (no notifications). Itll happen again minutes later
I factory reset it and it still is doing this
Any ideas of what might be wrong?
Gblur 3.5
mine seems to do the same thing, i have my timeout set for few seconds so screen stays on for little bit, i cant seem to figure out what causes it.
This is a longshot, but Fancy Widget has an option to wake up the device to refresh. Maybe that's what's going on.
i dont have that app, but i do have unlock wifi. and keep my wifi on all day. i do notice that wifi disconnects sometimes even though in power setting i said for it to always stay on. Thats another issue though.
ss2006 what apps you have that do background stuff? i know i have craigslist and ebay, but usually i cant see any notification making it come on like you said.

Help Archos won't go to sleep

For some reason I can't get my archos to stay asleep. after 8 seconds of sleep it wakes itself up, thus rendering itself useless as the batter dies in a matter of hours. any ideas? I've already factory reset with no effect, so it really can't be any software installed.
Do you have enabled deep sleep?
(Settings)
perhaps I was not clear it will not do any kind of sleep. no matter what I enable deep sleep disable deep sleep, what ever power setting I set the device automatically turns on after about 8 seconds. picture this, the device sitting on the desk the screen turns on, a minute passes the screen turns off, 8 seconds pass the screen turns on, repeat until battery is dead.
I don't have my Archos right now, but I would install adb on the PC, and do:
adb logcat
Then put device to sleep, wait for it to wake up, and try to figure out from the messages what app turned it back on.
You could also try looking in System Monitor at the Wake Locks tab, and see if there's anything scheduling wakeups.
(If it wasn't sleeping in the first place, I'd say check your USB host port & see if it died.)

[Q] Screen waking up while plugged (battery life full notification?)

When I leave my galaxy player 5 (international) plugged during the night the screen wakes up at some point which forces me to leave it with the screen down (when I remember), I would guess that happens when the battery full notification comes up.
That anoys me specially because sometimes the screen doesn't seem to follow the screen timeout settings and stays always on. It used to happen in stock froyo and still happens in eryigit gingerbread rom.
Does that happen to anyone else? Any tips?
I have the US version and when it finishes charging the screen stays on for about 3 minutes before turning off (I actually waited to see what would happen). I think it's a bug because my default settings is a minute. Try using different timeouts to see if that solves anything.

Pace - work but screen turn completly off

Hello
I have this problem:
https://www.youtube.com/watch?v=wtR1CzaUYho
The watch switch on, work, but after a couple of minutes the screen goes completly off. I see the watch is on because is paired with phone and counts steps, etc...
If I switch off, and switch on again its the same allways - after a 2 or 3 minutes the screen goes completly off.
Any solution?
