Noticing some image persistence today after going into settings. I could see the google play icon that has always been in the same spot. I could also see a couple of others. Seems to be going away now that I have a settings open for a few mins.
Guess I need to shorten the screen on time. Currently set at 30min. Had this TP since December.
the lcd isnt really capable of screen burn in. its only image persistence. mobile displays are bad about this. it isnt helping if you are keeping it on a 30 minute time out though.
That is a first one for me aswell because my display doesn't turn off unless i click the lock screen button. Post a picture to help see and fix the problem hopefully. usually how to fix it involves just putting a black or white picture on it for a good hour or so....but that's on a very old TV rather than the touchpad so like i said its a first for me
how about install "Dead Pixel Detect and Fix" from market to rapidly flash the screen to get rid of the burn in?
Here is a few ways to fix it:
1.Turn off the monitor for extended periods of time. It can be as little as several hours or it could be as long as several days.
2.Use a screen saver with a rotating image and run it for extended periods of time. The rotating color palette should help remove the persistent image but it could take a long time.
3.Run the screen with a single solid color or bright white for an extended period of time. This will cause all of the crystals to be reset at a single color setting and should erase any previous image persistence

Ok, so after doing all my searching and what not, it seems that for whatever reason the time it takes for the lock screen to time out is tied to the regular screen timeout.
What I mean by this, is when you first hit the sleep/wake button and its on the lock screen, but you don't unlock it, the time it takes for that screen to go to sleep is the same as if you had unlocked it and not used it.
For me at least, this is a major battery life issue. I like to leave the screen timeout at minimum at 5 minutes, because I use my phone's LCD as a flashlight quite often (LGP500 doesn't have a camera flash), and read websites fairly often. Also, I tend to keep my phone in my pocket (who doesn't?), so when walking or moving it's very likely one of the hardware buttons (sleep/wake, home etc.) will be accidentally pressed inside my pocket at least once every short while, basically keeping the screen on permanently.
I'd like to know if anyone has any ideas on how to change this.
Just as a side note, I realize it's possible for rogue apps to keep the screen from timing out, but I've made sure that its not the case here - when the timeout is changed to 15 seconds, the screen turns off at the correct interval.
Anyone have any ideas?
Ok, so I've found the section in 'Display' and switched Smart Stay on, but it doesn't seem to do anything. The small eye icon never appears on the notification bar, and the function doesn't work. I've noticed that with auto-brightness the screen is pretty much always really dim, and I noticed that smart stay won't work when the room is dim - does the phone think the light's too low and never switches the function on?
Hmm, off to try...
It does state when you activate it that it wont work in low light
Yeah, so perhaps it's the auto-brightness that's at fault? Been in daylight today and with the lights on at home - screen's been dim 90% of the time...
Right i too thought smart stay wasnt working. I too never saw the eye.
BUT... Having played with it some more heres how it works well in my eyes anyway
The eye icon only appears when the light is at the end of its duration setting.
For example i set mine to 15 seconds beacuse i wasnt sure it was working.
So every 15 seconds if your looking at your phone the eye will flicker on.
If its set at a minute you rarely see it as 60 seconds is a pretty long time to look at the screen with out pressing ought.
I hope this makes sense. Just set light time out to 15 secs to see what i mean.

I thought it wasnt working properly since every now and again id spot this icon flashing up and going just as fast as it came on, but i figure, its a battery saving method, so it wouldnt permanetly be tracking your eyes with the camera like the xbox kinect for instance, it comes on for a split second, if it recognises eyes are open and looking it stays on if not it turns off... i tested this, changed screen dim to 15 seconds for test purposes, staired at it whilst on web browser and every 10 seconds the icon flashed up and screen stayed on, closed my eyes counted to 10 and the screen was off
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.
I know the title sounds crazy, so let me explain.
I've had this issue for quite a long time now but never gotten into it.
Basically, when I open a white image or whatever light colored app/background, I can recognize a Whatsapp conversation in transparency, almost like it's stuck underneath the display.
So I tried opening the recovery to clear cache and I noticed the same exact thing when the recovery was loading (light blue background).
You can find a picture below. The top portion is my phone's display while the bottom is a screenshot found on Google (cause I needed the old layout for Whatsapp chats).
By the way, the phone I'm having trouble with is a Samsung Galaxy S6 Edge updated to Android 7.0 (the update didn't fix the issue).
Thanks to everyone in advance
This is known as image retention or burn-in. It is a characteristic of OLED/AMOLED displays when the same images are held at high brightness/intensities for long periods of time. There are apps/tools/methods which claim to reduce, remove or in some way fix the problem but please do your research as there is a good chance they can make the problem worse or introduce new problems. I have not investigated further other than methods of prevention. Also, organic light emitting diodes/pixels have a given lifespan. The screen will lose brightness and color accuracy over time. Blue diodes will fade first, then green, then red.
I think this is a bug – but it may be a stupid question on my part. Apologies if so. I'm primarily an iOS user on mobile, and the Gemini (which I'm loving so far…) is my first serious experience of Android.
OK, so I was playing with customisation options for my home screen, and although I actually really like the default dark blue starfield background that comes preset on the machine, I decided to swap it for an 'early morning sky' photo that I typically use on all my mobile devices. (It's a photo I took myself years ago, and works really well as a backdrop.)
After touching 'Set wallpaper', I elected to set my new background for both home screen AND lock screen. Fine; that worked OK and looks good. But I subsequently changed my mind and wished I'd stuck with the standard starfield for the lock screen. So I went back to the wallpaper options to change the lock screen only.
At this point I discovered the problem/bug. The thumbnail of the starfield picture is still there to be selected, and if I touch it, it covers the screen like it did before, so everything appears OK. However, when I click on 'Set wallpaper' and choose the option, regardless of what I choose (home screen, lock screen or both), there's a pause and then the starfield vanishes, leaving me with a completely black background. I can set the background image to any new photo that I supply myself without problems, but any attempt to reapply the original starfield graphic fails, which is rather a shame.
Can anyone tell me where I can locate the starfield graphic on the system? I've tried browsing the file system (with hidden files visible) but haven't found it. Or can anyone perhaps supply the file so that I can copy it back to the device if perhaps it only now exists in a cache or some such problem? I'd really like to get the image back.
Thank for any help.

Can confirm I have the same issue after re-flashing with the latest stock Android. Explains why I've still got a black screen!
+1 , same thing seen (or not seen if you prefer lol)

I believe this is a bug. I got around this by a long winded method. I selected the "star field" thumbnail so it covers the screen. At this point I took a screen shot by pressing Fn + R and then you can go to your gallery app, select the screen shot image, crop anything you don't want such as the bar at the top and then set the edited screen shot as your background. Hope that helps.

Thanks for the suggestion. That's a good workaround.
