Hey Guys,
I'm having a weird issue where the screen brightness keeps changing itself every time I turn the screen off. I tried disabling Smart Actions & Automate It (tasker-like app), changing the brightness in the display setting, unchecking the display power saver option. In all cases if I set the brightness to 100% after turning the screen off and then on again the brightness will be down to like 10% or so, although the indicators I have will still tell me the screen is at 100%. Any ideas?
Thanks.

Me too, it only happens randomly though, i thought it had something to do with the"Lux" app i use to control brightness.
Do u use any screen protectors? It could b interfering with the light sensor
Sent from my ICS Moto Razr XT910
There is a screen protector but this is happening when brightness is not set to Auto. It's set to 80% and every time I hit the power button and then turn the screen back on it dims to like 0-10%. I've tried closing all running processes and it still happens. I also tried resetting the phone and it initially wasn't doing this but once I setup all the programs it does, so it must be somehow related to a non-running process program configuration. Any ideas?
Thanks
Edit: Found out it was the Lightflow app, uninstalled it and no more brightness dimming issue.

interesting. I had that app installed for a while, maybe it messed something up that uninstalling didn't fix. I guess a hard reset is in my future. sigh.

i tried the star hash 0 star hash on dial pad, to bring up the test centre. I clicked on every box including dimmer and sleepmode to test it.
Now since then, every time i lock and unlock my phone, the brightness reverts back to some minumum setting. I can still change brightness when i long press the notification bar but it will always change back to the low setting. And i also cannot get into settings/display/brightness...its greyed out.
I have tried turning my phone on and off again
Help what did i do wrong
If your battery level is below 15% i think, the phone will disable the brightness control in the settings, greyed out, and will run at lowest brightness, until you charge the phone.
You can use the power control widget to adjust the brightness, but as soon as the phone goes to standby and you wake it up it will be back to minimum brightness again.
ok thanks, coincidence in timing when doing the lcd test and low battery..got me in a panic because I didn't have power saving mode enabled.
Yeah, it got me worried when it happened to me, as i was not using power saving as well, it`s a bit of a cheek to force low brightness when the battery is below 15% , the camera also does not work as well, great.
I have all the right settings and everything but the damn screen won't stay on for more than 10 seconds.
Screen Timeout is set to never turn off.
Power Saver is off.
No automatic lock.
This is so annoying when i'm trying to read anything, i have to keep touching the damn screen.

Theres a nice app in the market called "keepscreen lite".
It's free and you can configure each app so that the screen wont turn off for them.

By default my device keeps the screen on 1 minute. I've never changed it. It does seem to work fairly well by default.
If you're using a custom ROM, there could be an issue with the ROM. Might be best to post in the developer's thread to alert them to the issue and also to see if others are experiencing.
The main setting I've relied on is under Settings-> Display -> Screen timeout . Mine is currently set as the stock default of 1 min.
Hope that helps!
I have the stock rom, and my screen timeout setting has been at 2 minutes since I first go it.
I'll check out that APP that you suggested j4n87. Thanks
LATER: Sweet, that app works great. I still wish that the system settings actually worked like they're supposed to.
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 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
Hi,
I have this issue with my watch: sometimes I can light-up the watch by touching the display and most of the times this doesn't work. Is this a feature (when it works) or a bug (when doesn't work)?
Thank you!
Just few seconds after your screen goes off, it would get back on by tapping on screen. In other cases you couldn’t make it on by tapping.
I just hop on this thread about screen light.
I trying to find the setting to turn off the screen while on running activity. I notice the screen is light on entire running activity until complete. I had already enable wrist lift option to turn on the screen when i need checking the running stats.
Anyway find the setting to turn it off or perhaps sleep mode. Thank you in advance.
There is no such option in Zepp yet. Hopefully they will add it, since screen-on is very battery-consuming.

You can turn it off by going into workout settings.
If you disable light on lift, touch to light up display will be also disabled. At least it happens on mine.
