Does anyone else's screen have a warm/yellow hue to the whites?
I turned the white balance/color temperature all the way to cold in order to not have a yellowed screen, but it still seems to be filtering over with a yellow hue.
Could it be possible that you have "Night mode" activated?
Night mode warms up your screen in order to reduce fatigue, typically I only use it during night time but you could have accidentally turned it on.

No, its has never been turned on. What I have noticed is that on occasion, mostly when using Chrome that whatever is happening stops temporarily, so I imagine its some software thing.

Chromium-based browsers now also support "night mode". Not sure if related...

Dear all!
I am really in despair
I notice a strange phenomenon on my Galaxy S 3 (German version).
Sometimes there occurrs a flickering of the screen. It is caused by thin greyish horizontal lines which jitter with high frequency at some parts of the screen. You should not imagine it as some blinking of the whole screen. It's only a partial jittering of thin greyish lines.
It does appear at random, I cannot force this effect to occurr. Most of the times it's subtle, but sometimes it is clearly visible.
I read in some other threads that people noticed flickering in dependence of the power saving options. This I observed as well. But I don't know why. Unfortunately, none of the other threads came to a conclusion. And the problem seems to affect only very few devices.
My S3 was sent into repair twice. Two times the touch screen was exchanged. Last time they also changed "some electrical and mechanical parts". However, the flickering still occurrs.
I now tested for a while and made the following observations:
- it's not related to 3g, wifi or mobile connections in general (occurred while switched off)
- it's not related to "automatic brightness control" (occurred with manually set brightness, 1/3)
- it's not due to the display (they changed it two times)
- it's not related to ambient light (happened both with artificial light and in darkness)
- it's not related to the setting "adjust display color"
- neon light helps to trigger it, as well as switching the screen on or manually changing the brightness
- it's not related to any one of the single settings in "energy saving mode"
- flickering "survives" switching the screen off for a short time
- switching "energy saving" off always finishes the flickering
Can anyone shed light on the reasons for this?
Try unticking the second option in Power Saving mode, which is supposed to lower the FPS in order to preserve power. You can still user PS mode but the flickering should be gone.

thank you!
i already unticked all single options there. didn't change it. the only solution is to switch the whole "enrgy saving mode" off as it seems.

I am sorry, I did not read the OP carefully enough, where you stated that

I am using PS mode with all the options checked all the time, I don't think I have ever disabled it, and I haven't noticed the issue you mention. Can you tell us more about root status/ROM/kernel on your device etc? Also, have you tried disabling PS mode and observing the phone for 24 hours or so, to see if it still does the flickering at some point?
I'm having same issue. As for the conditions my result is that it would only appear after wake up when power saving is on with lowest brightness. Also it's not noticeable on dark wallpapers. Any ideas other than "turn off" power saving mode?
Just to add, I'm running stock 4.1.2 version which didn't fix this problem and I was observing phone without PS for a few days without any flicker of this kind.
Hello,
the following problem appears when i try to unlock the phone after some hours: i can see my home screen, but the screen stays extremely dim. When i try to start an app (e.g. browser) the screen turns black. I can unlock it again, but the screen stays dim. after some unlocking the screen becomes normal (normal brightness) and also the apps are startable.
i am using autobrightness, the stock firmware, 4.1.1 (i9300xxdlih) power saver is not turned on.
thx, i hope you can help me solving this problem

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem
When I double tap the button to turn on theater mode, the screen doesn't appear to actually turn off. If I'm in a very dark room I can make out a faint red tint on the screen. This is different from when the device is completely off. Any ideas why (I assume because of the LCD screen) and/or how to turn the screen entirely off?
I have the same problem.
Did you find a solution?

Nope. I assume it's an unfixable hardware issue.
I've noticed at night that my screen is redder than during the day. I've checked all my setting and the blue light filter is not on and there is no schedule set. Anyone else notice this? When I turn on my screen it will often be normal colors and then quickly shift to a red hue. If I turn on the blue light filter, it gets even redder.
I've noticed the same thing on mine. Looks like a double filter. First one maybe from native android and second one from Samsung. Can't find the setting for the former one though.
I found these settings to work well and looks great where I set them. You can try that and change to your liking in reference to your eyes.
Did you upgrade from a phone with night mode, while night mode was turned on? I saw a thread somewhere than said even though the S9 doesn't have a night mode setting, if you imported settings from a phone that had it enabled, the S9 will still trigger night mode., with no obvious way to turn it off. IIRC, he had to use ADB to change the night mode setting.
Let me see if I can find that thread again.
Edit: Here it is:

And here's the ADB fix if you don't want to install Nova Launcher:

That was it. Thank you very much for that. I didn't even consider that native android night light was different from the Samsung blue light filter. Excellent work. I appreciate it.
Funny thing was I would use nightlight/blue light filter, it was just the fact that I couldn't turn it off if I wanted to.
Everytime I flip my phone over the screen turns off after a couple of seconds. Really annoying in games and videos-- are there any possible fixes for this?

Maybe you have "Flip to Shhh" turned on (settings\system\gestures) which I think also turns off the screen. I had it on for a while and noticed this.

Thanks for the response!
I just realized the actual issue, uninstalling digital wellbeing from ADB caused my "flip to shh" gesture to go away, and disabling usage access just causes the same problem of turning the screen off again. My only solution is to keep digital wellbeing untouched.
