Wake up brightness keeps resetting - T-Mobile Samsung Galaxy S II SGH-T989

While I'm at home in the evening, I've been trying to turn my brightness down to the lowest level. I tried the system slider and also tried different widgets and apps bit there has been one issue with all of them. Every time I put the phone into sleep/lock, the brightness setting doesn't stay are the lowest setting. (Auto-brightness off). The brightness would reset to 20 - 30%.

There's probably an app you have installed that is messing with it

Go to
Settings --> Display
There's another option called "Auto adjust screen power" which auto adjusts LCD brightness as well.
Just a guess really.. Hope it does something for ya

I think you have automatic brightness turned on. Go to Settings -> Display -> Brightness. Uncheck Automatic brightness.

Its a problem with the auto bright and the polling interval. its just not doing smooth transitions. Work in the settings to get it to smooth out. i used to have this issue, dont remember exactly how i fixed it though.
Are you doing anything with the special settings under automatic backlight in CMsettings? or just using the auto brightness in the regular Android settings? I'm using no special stuff in CMsettings and mine works fine.

Two weird things I have noticed

Screen Brightness: I have set the screen brightness to medium and and timeout to 60 seconds. I have started to notice that it will change the settings on its own. I will notice the screen is dim then look at the brightness setting and it will be set to minimum. Another thing that is driving me crazy is that it will dim the screen if you don't touch it regardless of the screen time out.
I have also noticed that sometimes when typing the screen does not follow were the words are going.
Other than these two minor pet peeves I absolutely love this phone. If it had a vag it may replace my wife.
The screen dimming is probably done by u. If u run your hand back and forth at the bottom of the notification bar it will change your brightness. Auto brightness has to be off. Its a cool feature that the original epic had.

u might want to disable the "power saving mode"... i had the same issue as u, but it seems to be fine since i disabled power saving mode
That's the thing I have my settings to auto brightness off
Edit: I will try turning the power saving mode off
Did not know that about the notification bar dimming the screen that's a cool feature.

Thanks I bet the notification bar might be it. That is awesome, I can't believe I didn't know that yet.
IF your in the internet browser that came with the phone and you turn up your brightness all the way and then you notice while your look at page all of a sudden your brightness will go back down to like 10% I found out the culprit.
the browser has a BROWSER BRIGHTNESS option in the menu. you can turn auto on or theres another slider there and it appears factory setting is all the way left or lowest.
this was pissing me off today while I was waking in the sun, I thought I had my brightness on all the way but with in 5 seconds while look here on XDA, the brightness kept going back down on its own and I do not have auto on. the thing I was doing to get it back up bright again was to do the notification swipe to the right and that would only temporary fix it.

[Q] Screen dims when using email app

The screen on my G Note 2 N7100 dims whenever I open the stock email app. Initially, when I set up the very first email account the brightness was normal but after it finishes and goes to Inbox it went darker. I've tried tweaking the display setting but have not been successful and it wouldn't be productive to manually toggle the brightness whenever I am using the email app. When I leave the email app on to home screen or any other app the display brightness returned to normal.
Is anyone experiencing similar issues? Any thoughts to fix this?
Is it the "auto adjust screen tone" setting?
i am facing the same issue. tried lot of things but no success....seems this is the way this app looks...disappointment

Try disabling "Power Saving" mode.

Hey @amf, you're right...sort of. It's the Power Saving mode that's messing with the screen dim but as I pointed out this issue only occur with the stock email app. Every other apps I tried were fine with Power Saving mode on. With that said, I found that you don't have to completely turn off Power Saving, just uncheck Background Color and leave the rest checked. This is strange because I thought that Background Color is supposed to dim for bright background to reduce power consumption but the email app's background is black.
Anyway, thanks everyone for replying! :good:
Hi,
The darker the background, the less battery it consumes. It seems to make sense when you turn on Power save mode.
Cheers!!

[Q] Decrease Minimum Brightness?

Is it possible to decrease the backlight of the phone even further than the minimum (for using in bed)? I tried modifying the min brightness setting in build.prop and it makes the brightness slider go further down, but it doesn't actually get any more dim. Is there any way to set this other than using a "screen filter"-type app. Thanks!
Yaab from the market, try it out

use and app called screen filter. it places a transparent layer over the screen and dims it further. it works better on amoled than on led lit screens since amoleds don't use a backlight. with led backlights it doesn't dim it, just darkens the images (backlight level remains the same).
I can't remember why I settled on Display Filter instead of Screen Filter. But there's another option for you.

[Q] i316M - Screen Dim

Hello,
Whenever I use the default internet browser on my Note 2 (i317M Telus) the screen dims to the lowest setting. It stays like this even though I haven't touched the brightness setting. I can change the brightness setting but when I exit the internet app the brightness changes to what it should be. Any ideas on how to fix this problem? Thank you.
inb4 install a different browser
inb3 OP can't inb4
There is a separate brightness toggle in the browser for some reason. Just hit menu then brightness.
For me it uses the same "brightness" setting, but when I change the brightness in browser it changes it for the rest of the phone.
Make sure "power saving mode" isn't enabled. It defaults the browser to extremely dim. You can of course, turn that option off
