Is it possible that quiet notifications are waking up screen when u set screen to wake up when notification arrives? Maybe it could be that, someone else might know it better.

Check under settings/battery what eat battery or which program wake up screen and download app from play store to see what is going on

The screen light on when i ....

The screen is turning on when i lift my phone up from the table.
When i for example put my phone on a table, the screen is turning of about 30 second, when i pic my phone up the screen turning on automatic whitout any touch on a botton. Should it was like that?

display on the table or back (camera) on the table
I'll explain my question: although I'm assuming it shouldn't work that way (at least by default), if you have the display facing down, it might be waking because of the proximity sensor. As you lift the mobile from the table, it behaves the same as if you were moving it away from your face after a call, and wake the screen up.
Actually, this would be a nifty feature for many people, specially now, with JB lacking a way to use the capacitive buttons as notifications. Considering they probably lift the phone a few dozen times a day to check their messages/missing calls/emails and only a couple times to actually put it somewhere else (and even then they probably check the missing calls again), it would save them some time

I search for that on the "Store" but a few came up...
Maybe is a app feature, don't know.
What I know (in stock) is that if you set the screen to lock, after get locked and screen OFF, only power button is able to wake up the screen
allowing the slide to unlock.
mine comes on sometimes too,soon goes back off, dont bother me too much
After the update to Jelly Bean, my Display always gets activated for a few seconds when I receive a Message.
Is there anything I can do against this?
Or am I the only one with this "Problem"?

Screen randomly glows when screen is switched off

Hey on my Xperia Z stock rom nothing flashed, when it is in standby (screen off) randomly the screen glows and does not stop, like the screen is still off but it's like the back light has come on? is this normal? seems to be a power wasting thing to me. unless i look at it from a slight angel (during the day) i can not actually tell it's on, i'm assuming this is why my screen is using 60+% of my battery is there a fix for this?
Are you using any power saving mode?

Stamina mode.
I have the exact same thing happen, and it is definitely a pain as like you say you can only notice it when looking at an angle, and as I have a flip case on mine I only notice while charging. It is just a case of pressing the power button twice to turn off but that is obviously only when you notice it's doing it! lol
I use stamina mode on mine (which is great) but not sure if this is anything to do with the backlight being left on as it only does it sometimes?
I had this issue when i first got my phone ,and not anymore.Not sure how it solved cause i did lot of factory reset and flashing firmwares.
Are you using light flow or any third party apps?
Sent from my C6602 using xda premium
I get this too. I get it when it's locked and it comes back on. Also when I unlock the screen sometimes this happens and I have to turn the screen off and on again to fix it.
Happening here also but not often. I thought it was low battery mode but happens when it's disabled as well.

No i'm not using any third party light apps, seems like this may be an actual bug if multiple people are experiencing it
I have only done one reset/repair to fix the LED notification light bug.
Hope this helps
I know how to fix this. I have an xperia z1 so im not sure if my problem is the same but i use my phone as an alarm so i notice at night the screen is glowing while its standby. If you go to settings or maybe you have it in quick settings go to brightness and deactivate "adapt to lighting conditions" then it should be a black screen woth no glow in standby mode

display problem

Sometimes i noticed while charging or on zero brightness my display is very wierd or greyed out or colours are messed up. Increasing brightness usually solves this

Hmm. Did you noticed another thing. One low brightness if you look real close, you can see, hmm i cant really explain, but its like the display on TV on low voltage., to better recognise the defect you would need some specific light colours on the screen like grey, yellow etc
and while charging.....touch sensitivity decreases....I have to press a little hard for selecting!!
does anyone have this prob?

It's true. When i use blue backgrounds i can apreciate

I have seen sometimes the whole screen turn yellowish or so. But it disapperas after a restart
Is these problems limited to Samsung galaxy s advance or other Samsung phones. Does other phone of other companies have these problems
from my experience some of these things are related to unappropriate charger. especially screwed sensitivity
It's normal for amoled screens. My father have the same problem when charging phone but grayed screen is only in s adv. I have one more issue. My right side of screen is 'sharped' on red colours. I can see little stripes on it but only when it's red.

Lock Pattern Breaking off
Sometimes, when i try to draw my unlock pattern, it cannot be drawn as a continuous pattern. It breaks off as separate points. It is really annoying as I cannot unlock my phone, even after cleaning my fingers&screen. And since single point tries don't register as failed tries, it does not say "too many failed attempts" .
Do any of you have this problem? possible reasons/solutions??
thanks, in advance.

I get this problem while charging sometimes. But its rare. Sometimes even if didn't enter any other it will lock me out saying
"too many failed attempts"

Why can't I see my lock screen?

If I press the power button I see it, but if I press the home button it goes straight to home screen.
I have fingerprint, and face recognition set up, and have the phone lock after 5 minutes of being idle, or instantly with the power button.
I'd like to see my lockscreen, can anyone help?
Verizon Note 8, if that matters.

Turn off face recognition and turn off unlock with home button in nav bar settings.

Now it isnt showing the lockscreen when pressing the power button either.
Only time it shows the lock screen is when the phone is locked.
Is this just how it is?

Unlock with Home button is turned off
Turning off face recognition doesn't change behavior
Sent from my SM-N950U using Tapatalk
Just checked. When I disable unlock with home button I see lock screen. But when face recognition is enabled lock screen appears only for 1-2 seconds. I'm using Smart Lock and phone is always unlocked.

What happens if you press the home button but tilt the screen away from you so it doesn't see your face?
My lock screen comes on only when the phone is locked, otherwise it bypasses straight to home screen.

In my case only way to see lock screen is turn off face recognition or dont't look at the phone.

If the camera can see your face, its going to unlock. If you can see the lock screen, then yes, your phone is locked. But if you have face unlock, the camera will unlock your phone.
If you disable the second toggle in my screen shot. Then you would still have to swipe when you see the lock screen for it to use face unlock.

Turning that toggle off enables a swipe to activate face unlock, and leaves the phone at the lock screen.
However, if the screen is turned off but not locked, it will still bypass the lock screen and go straight to my home screen.
Is that normal behavior?

Yes. That's normal. If you want the lock screen press the physical lock button. The pressure button is a universal home button I suppose.
Seems like an odd behavior and completely different than my previous experience with Samsung phones where there lock screen would always display whether or not the phone was locked.

Yeah it's their first go at the pressure button. Maybe there will be more options in the oreo rom to adjust it's behavior.

Any app to turn off the screen even if I'm using it?

So, I want an app that will turn the screen off after 30 mins even if I'm using it or watching Netflix or gaming or whatever.
This is because I have had fall asleep with my phone on before and the screen was on for like 6 hours cos I was in contact with it. So I want it to turn off no matter what after 30min.
Any app to do this? The simpler, the better.

Thank you, but I'm looking for a way to turn off the screen after 30m ALWAYS, without the need of setting a clock every time.
