How does the screen dimming/time out actually work? - Samsung Galaxy Note 8 Questions and Answers

This has always been confusing and I am looking for clarification on the Lock Screen/ Screen dimming, etc.
So I went into the display settings and set it not to turn off for 1 minute. Then I checked the power saving settings just to be sure the screen would not go dim or lock after 5 seconds. That did not work. Then I checked the security settings to see if something was over ridding every other time out setting and I am lost. Either these settings have never really worked since the original note and android/ google is lazy or I am not doing something right.
Dose anyone have a step by step walk through of all the settings that would affect when the screen dimms and when it locks? (Sometimes I am running music through blue tooth and I don't want to the screen to dim for specific applications also. There has to be a setting somewhere because Google Maps does not allow the screen to dim or lock when in nav mode.

I really wish someone would have answered your question. Mainly since I have the same freaking problem.
When the phone app is running, I am constantly getting dimmed, seconds only to do something.
Tonight I was using an app that monitors BBQ temperatures. Always dims to fast. Set the screen timeout for 10 minutes. Still dimmed after 30 seconds or so.
How does this work? I'm not sure the screen timeout setting does anything.

The screen diming feature is part of the auto brightness function and works by using the ambiant light sensor to adjust the brightness of the display. According to the amount of light detected in front of the display.
Screen locking happens when you haven't used your device for a specific amount of time.

It dims before it locks. That's what I was referring to. I think the OP was as well.
I set the display for 10 minute timeout. It dims and locks the screen in less than a minute. I can't figure out how to stop it.
Is that a clearer question?

Well my screen dims for some seconds before going out, but, always as per the time I set , for instance, if I set to go out after 5 mins of inactivity, it dims after 4 mins 55 seconds, then goes out, I dont use autobrightness, and I use entertainment mode

It was secure lock time setting.
It was disregarding the screen timeout.

Can't stop my N1 from dimming the screen after ~20 seconds when plugged in

Hi all,
I've had a search around but couldn't find this particular issue discussed.
I have a N1 running CM7. When the phone is plugged in (either on my desk, or in the car) the screen will auto dim to a very low level after approx. 20 seconds after last touch.
This happens if the brightness is set to auto or a manual level. I've gone through all the settings I can find but couldn't find anything regarding this. I have got developer > stay awake enabled, which I guess stops the screen from actually sleeping, but it still goes dim.
The CM7 auto dim settings are disabled.
Any advice folks? I want the screen to not auto-dim after 20 seconds. Out of interest, the 'Car Widget Pro' widget seems to be able to force the brightness if you choose something other than 'auto' in the widget settings. So perhaps I am missing something somewhere else?
It's a real PITA when trying to navigate in the car with google maps as whenever I touch the screen to get the brightness back it disables gps tracking and I have to re-hit the icon, which is distracting whilst driving..
Here's hoping..
Hey, I'm only posting because I had a very similar issue. What I did was go into display settings (while connected via USB) and changed the timeout to one minute (or whatever you want). For me, when I went to change the timeout, no item was selected by default. This happened to me after I installed WidgetLocker for some reason. I doubt I will help but I had a very similar issue...

Any way to change display timeout for lock screen specifically?

So i just noticed this for some reason but I have my display timeout set for 2 minutes which is fine
but when i get a text message or a missed call and it leaves the screen on for 2 minutes as well. i figure this could be a battery drainer over time especially if im not at my phone to lock the screen back
is there a way to set the lockscreen display time independent from the system display timeout? has this always been the case? For some reason i always remembered the lockscreen turning off relatively shortly after a notification. maybe im just going crazy:silly:
bump...is this kinda common sense that the lockscreen display stays on for however long the system default for display timeout says to?
i could have sworn the lockscreen didnt stay on for a minute before it turned off even though my display was set to "sleep" after a minute

Screen is too bright when unlocking the screen?

Anyone noticed theirs? Mine auto brightness is already activated, when I unlocked the screen it gets bright even when the environment is dark. But my auto brightness mode is working.

Yes it's annoying as all hell. Takes about a minute to adjust but it's blinding at night.
That happens cause I use iris. So in dark rooms, I just use the fingerprint.
If you don't mind the inconvenience caused by having to swipe first before using iris unlock, disable the "Iris unlock immediately when screen turns on" option in Iris Scanner.
The screen has to be brighter than normal initally in order to provide enough light for iris scanning (without the circles for guidance).
The screen is no longer brighter when using iris unlock later because it now requires you to position your eyes within the circles.
Personally, I'm perfectly fine with the brighter screen initially.
At home you can get around it by setting it as a trusted location and then go into display/navigation bar and switch "unlock with home button" to on. That way you can just press the home location and your phone will bypass security/lock screen and go directly to the home screen. That is you can if you're not hiding an affair or other skulduggery from your partner in which case you might want to skip this method. lol
Anyhow you will retain your set security method outside of the trusted location, in my experience I'll usually be trusted around the house and yard but much past it I wont be. This also makes it nice for when you're home with the phone next to you and you want to interact with it without picking it up, you press home and you're in.
Unlocking screen brightness on Android.
This is only an Android Oreo + ( Android 8.0+). I only have this issue with my newer phone which is Android Oreo. It happenes with whatever method I use to unlock my phone. It's an auto brightness setting but it's doesn't seem to be listed as any sort of brightness setting. It's not even in the developer settings. If anyone knows how to disable the unlocking brightness feature, that would be helpful.
This happens for me when I face recognition on so the camera can see my face in the dark. You can change this in Settings > Lock Screen and Security > Face Recognition > Brighten Screen. Turning Brighten Screen off should keep the screen dim in the dark but you'll probably have to unlock with your fingerprint or something.

Really annoying this brightness. Even try every thing to keep this brightness on manually set point but at time of unlock, it increase in the middle of the night. Please any one help. Is it a problem of software or hardware.
I haven't notice this at all...
The only problem with this glorious device
I'm on Note 10+ and this is the only issue with this device. In the last three months I've used Pixel 3 and Apple Max and they've both figured this out. The blinding light is terrible. Middle of the night, or first when you wake up.
SOLUTION - If you have fave face recognition:
- Go into settings, select Biometrics and security.
- Select Face recognition.
- Tap on the switch on the right-hand side to turn on/off.

Not working yet? Smart Stay-like “Screen Attention”

This setting doesn't seem to be working for me, and this is one of the biggest features I want enabled. I would think could be a massive battery saver, but also extremely convenient. Reading a long article online, sometimes I'm just staring at the screen, not moving touching the display, and makes so much sense for a Face ID thing to see your eyes focus on the phone to keep it awake. But then I would guess can save battery, as when your done viewing the phone, and put it down, the screen turns off.
Android Q adds support for a Smart Stay-like “Screen Attention” feature
https://www.xda-developers.com/android-q-smart-stay-screen-attention/
Settings > Display > Screen attention
I enabled this in the settings, then I set my screen time out to 15 seconds, to save battery, but thought this "screen attention" thing will keep the screen on for me, when reading news and stuff , as the face ID thing will scan my eyes keeping the display on. Well it doesn't seem to work, if I just stare at a web page for longer than 15 seconds, the screens turns off.
Huh, wonder if the dwell time is just too short. Samsung's version didn't work well for me with less than 30 seconds.
Works for me. It does say that it uses the front facing camera so maybe it doesn't work in poor lighting.
Screen Attention doesn't seem to work for me? I have my display set to 30 seconds to shut off, but if I read an article on my web browser for 30+ seconds, the screen fades to black and turns off.
I have Motion Sense on, but not everything enabled, but I do have Lift Wake, and Reach to wake, and Tap to wake enabled.
Unless there's some other setting I am missing specifically for Screen Attention to work?
Screen Attention has so far been hit-and-miss for me. It appears to be working most of the time, but I have also had it on when the screen just dims and shuts off as I am reading. No poor lighting issues here. This was observed in daylight.
Works for me without issues... How do you hold your phone. Maybe you need to have a thumb in front of the screen so that soli can see something there?
The feature uses the camera. Mine has worked fine but I'm on 1 minute.
Mine never seem to work besides the first day. It's just easier to set the lock to 1 minute and don't bother with screen attention.

Ambient Display / Lock Screen Settings

I've chosen that the ambient display should light up whenever I'm near the phone. However, it stays on for about 10 mins even though I'm not near it. Sometimes it just stays off even though I'm nearby and even lifting up the phone. What settings should I use?
I would test that the proximity sensor is working. Try using the Pokémon wallpaper or app to see if it recognises that you are near and waving your hand. I only say this as my first pixel had a faulty sensor and I had to return it. If yours is too it might explain why it isn't working.

Pokémon reacts fine and proximity sensor works just fine.

The same here. I changed the Idle Lock Screen to OFF and let the other settings ON, this works better for me.

No I haven't if you mean DND. Sometimes also after a restart the phone also needs to cycle the power button.

Check your screen timeout settings in settings/display and change it to whatever you want, like maybe it's set to 10 minutes so set it to less minutes or disable completely.
Screen timeout is set to 1 minute and tried to change it to 2 mins. With same result. Weird ?
