I Have A Question For Dev's to see if this could get implemented into the Rom's.
I have noticed that the hardware or softkeys (home,menu,back,search) the backlight is always on, and its very distracting and I imagine it consumes battery.
Is there any way for this to get shut off, like on the Evo 4G that when pressed they would turn on for a couple of seconds then shut off again..
I've noticed this only happening when in dark rooms or night. I think its a light sensor tweak that should be the culprit.
Yes there should be. I use a program called Screen Filter and it turns off the soft keys. If that program can than I am sure there is a way to mod your rom to do so as well. Try downloading it and playing around with it. Reverse engineer the .apk if you have to I guess lol.
Hey Guys,
Initially before I got my phone I had another perception on how smart stay works and was a bit disappointed...
My thoughts were, that if you are reading something it checks up on you if you are still looking = Screen stays on and if you look away it turns off.
The breaking point in what I thought was, that after the screen has shut down and you look at it again (Lets say a time frame of 5-10 Seconds) it turns on again.
I hope some DEV reads this and could make a MOD or something like that. Would be really cool and I dont think, that programming that is that tough.
Regardless of this I would love to have Smart Stay as a toggle option in the 15 Toggle mode or something, is that possible?
Thanks in advance
think that you have put your phone aside after looking at it. And it will have to monitor your eyes on that time too. Too much battery drain because camera needs to be on all the time! this is why samsung didnt enabled this!

The camera does not need to be on "all the time". The way it works is as follows:
- The screen timeout is set to a certain time - let's say 30 seconds. After 30 seconds have elapsed, the screen will turn off if Smart Stay is not activated.
- If Smart Stay is active, after 30 seconds the camera will switch on and determine whether you are looking at the screen. If it determines you are, it will trigger the screen to stay on for another 30 seconds, after which it will do the same again, and so on. Once it has confirmed you're looking at the screen, the camera will switch off again.
Hence in fact the camera only needs to go on for a very short period of time - just enough to see your eyes, basically. You'll know it's doing this because it briefly shows an eye icon in the notification bar.
Yeah and I meant that after the screen is off it just should monitor for another 30 seconds or so

Which would increase battery drain tenfold.

ok lets say screen is turned off and camera is checking eyes once every 30seconds. what if I happen to look at it on the 15th second
i have put this in smart stay threads before, if only people would search before asking questions.
anyway, in order for smart stay to work well this condition must be met - open front camera and look at it if you can see your face and it isn't darkened then smart stay will work well. because some may ask that smart stay doesn't work even if lighting is good, that is because your face is darkened because of shadow and you are at the back of lighting.
if that condition is met then :
1. smart stay should be enabled obviously. set screen timeout to 15 seconds.
2. look at screen, you will see in 5 seconds the eye icon for smart stay will light up
3. turn your phone at an angle away from your face but enough that you can see the eye icon 5 seconds later.
- this time the screen dims but not turn off.
4. face phone screen again, 5 seconds later eye appears the screen brightens up.
5. repeat step 3, screen dims. then this time remain not looking at screen.
- after dim, 5 seconds later eye checks again and detects you're not facing screen thus it turns off screen.
now some will be thinking, having the front camera turn on at intervals will just use more battery. the thing is,turning the front cam to sense your face for just about 2 seconds at intervals won't consume as much battery consumed as compared to the display still turned on for 15,30seconds,1minute or more even when you're not using the phone.
purpose of smart stay:
1. already well-known since this is what they advertise for this feature, keep light on so you don't have to annoyingly touch the screen at intervals you think the screen timeout is nearing so as not to be inconvenienced by the screen turning off when you are reading or browsing.
2. THIS IS THE MAIN PURPOSE - to turn off display way before the screen timeout because there's no use having the display still on when you're not using the phone. we all know the display is one of the things that can drain battery fast. this is very helpful for those who set there screen timeout to 1minute or more.
note : the time interval for smart stay checking/eye appearing is different for the screen timeout interval you set.
a bit harsh but quite correct, he took time out to give you an explanation, and a very good one, a hit on the thanks button is what you should have done! Nice one radeon :thumbup::thumbup:

Also, don't forget to mention "SMART STAY doesn's work in dark". It can't see your face well.
ok, some info, i'm coming from the captivate (SGS1), on that phone if you were in a full screen app, or the camera was active, the screen wouldn't turn off regardless of the time out setting.
on this phone i have the timeout on 30 seconds with the stay on mode enabled for when i'm looking at the screen, this works really well except the above doesn't work, when the camera is on or the app is full screen it still times out. this becomes REALLY annoying when doing things like google hangouts as it hangs up the call when the screen turns off.
am i missing a setting? how can i keep the screen on when the app is full screen (games, movies, etc)?
thanks
Sometimes when turning on my Display it looks green and with horizontal lines all over it. Screenshot doesn't capture it. It has been like that for a while but just got way more frequent. A reboot fixed it and i noticed now sometimes also just trying again to turn on the display sometimes fixes it as well as charging it while doing so.
Since it got more frequent theres also this high pitch sound when i turn on the display and the green distortion happens. I have no energy saving mode enabled. Anything i can do or do i need a new phone/ display if it stays like this?
It's a known issue I guess try to keep the brightness high, it happened to me some months ago but for some reason it's gone now. If you need to lower your brightness (ex at night) use some sort of app (like twilight) which actually puts a layer on the display (the screenshots are darker)
I have a Xiaomi Redmi Note 9S which has the following behaviour: it works normally until the moment it goes under the sun, then (apparently only) the backlight of the screen is turned off and never turns on again until I restart the smartphone, where it works normally until the very moment it "detects" a bright light like under the sun, then the screen goes black. When this happens, sometimes you can still see the shape of what was on screen, but most times it only goes totally black.
When the screen is black, the telephone keeps working normally (music keeps being played, receives calls, vibration responses keep working, etc...(confirmed it using scrcpy and all is working normally)), only that the backlight is turned off and it keeps totally black. During the night, i.e. with artificial light, the telephone works normally (I was able to replicate the error using a strong flashlight above the telephone, the screen also went black the very moment I turned it on).
What I tried to resolve: restarted many times, disabled every auto brightness (also one that I think is a Xiaomi MIUI only, sunlight detector, something like this) settings that are in the configuration menu, restarted using vol up + power button. Factory reseted the smartphone. Disabled pocket mode before and after factory reset.
Any idea how to proceed? What is killing me is that it seem to be a software issue, like, why the screen don't turn on back after a while, but every time you restart it, or why the phone works all night long (i.e. there no strong light on it)?
How to capture the telephone log (logcat perhaps?) and be sure of what is the exact event that is disabling screen? Maybe I can manipulate it to prevent from happening, or to make screen goes back to normal after a while, as I work as a software developer.
