Hello!
Have some problems with my screen backlight.
ROM is Mahdi Mako 4.4.4 with root.
When in recovery mode everything is ok, backlight is at maximum but when i started android backlight goes wery low, like 5-10% , and it can not be controlled with brightness slider and with autobrightness, but it seems that brightness sensor is working.
All sensors were checked via sensor box and the same other utilities.
Problem is not in the ROM, the same situation was on stock ROM and i checked it on many other ROM's.

Hi, i have a problem with auto brihtness of my xoom.
If i set the display to auto brightness, it increases the brightness when there's more light, but it don't decrease the brightness if there is less light, until i lock and unlock the screen.
I've a 3g xoom with the latest 3.2 firmware.
Is there any solution?
Someone can help me?

I haven't heard of that issue, so I don't know of a solution. Are you completely stock, with no modification?
This is stock behaviour. Simply turn the display off and back on if you want it to re-set the brigtness to a lower value on the stock rom.
Thank u very much for your reply! I thinked that was mine faulty...
For now i solved installing Auto lux, that it's completely customizable(u can set a % of brightness for any kind of external "lux") and works very well.
Is there another way to solve it? Now i tried the tiamat kernel, but without any resutl.
Hi, started this thread to see if anyone had the same problem I'm having with my screen.
I have a Galaxy S4 GT-I9500 (Octa-core variation), it is running 4.4.2, rooted, stock Touchwiz.
The problem is that the screen starts to flicker almost as if it would want to turn off, when in low light conditions and auto-brightness on, it continues to flicker unless I set the brightness between +2 and +5. I can reproduce the issue without auto-brightness setting the brightness to the lowest, one notch above the lowest and there is no flickering. It is noticeable in white backgrounds and also when swiping down the notification center, that's the most noticeable instance but you can see it in the home screen and in any app.
I started noticing it when I had 4.2.2 Jelly bean (rooted), and I updated to Kitkat hoping it would be solved but it is the same, I updated through Kies and rooted, no Factory reset, I want to try that as last resort.
Funny thing I discovered is when I set Juice Defender to control my brightness it does not flicker even in -60% brightness, but when the dimming happens before the screen turns off it does flicker (and the dimming thing is controlled by the OS I think, not Juice Defender).
I wish I could put up a video but I don't have another phone to film it.
Anyone know if this is software or hardware? What can I do?
I'd like to add, that I changed the battery, disabled overlays in developers option, forced GPU rendering, tried Pimp my rom and played with all the settings, checked and unchecked every option in Display settings and it still flickered given the low brightness conditions.
I think I've found the best solution out there for most annoying screen flickering issues... Done a substential amount of digging and finally discovered the app "Twillight" works like a charm by enabling backlight control feature... Try it out first, then thank me and share your experience here ...
I've noticed with my G2 for quite a while that the screen brightness will dim by itself with auto brightness turned off. I have the brightness set at 70%. When I wake the screen and go to Gmail or any other light themed app where it's noticeable, the screen will dim approximately 5%. I did a little testing this morning and it only happens when the area is well lit. In the dark hallway, it wouldn't dim at all. I am running Cloudy G3 1.2 on my LS980. I've noticed the same thing on versions 1.3 and 2.0. I do think though, it's likely something to do with the proximity sensor rather than the ROM. I've tried different kernels and the same thing happens. I also have Xposed installed with the Tweaksbox module, but with Xposed disabled it doesn't change. I haven't had time to go back to stock and test but will try soon if nothing is resolved.
Anyone else experience this?
Anyone know if it is possible to stop the screen dimming just before it powers off? after a few recent ROM flashes it flickers when dim.
Note: this is nothing to do with auto brightness / screen timeout / Airview / Hardware fault or any settings that I can find.
I appears to be a system default that cannot be changed.
I am hoping that something in Build.prop or whatever can be altered, to either remove the dim completely or have the dim not go as low.
When battery is low or when turning it off?
And I think this is more kernel than rom related.
Never mind

Neither, it flickers as the dimmer comes on just before auto screen timeout blanks the screen.
only started a while ago after ROM/Kernel flash.
So I tossed LP on over the weekend using the FlashFire method so I'm rooted and things seem to be working well. My only real issue is that the auto-brightness seems dimmer to me than at 4.4.4. It works, that is I see the screen brightness automatically change when ambient light levels change, but inside, in a "normally" lit room in a house (no overhead florescent lighting) it is definitely dimmer than before.
Does anyone know of a tweak for this besides just turning off auto-brightness, which I'd prefer not to do?
my only other complaint about LP is the owner info not showing on the lock screen if you have the notifications enabled...
