My KJam backlight keeps changing by itself to dark

Suddenly my KJam backlight always turns to low without me doing so, then I have to change it to high, barely can see what I’m doing as it is almost black. This is kept happening especially after I installed Pocketweather. I reinstalled the Rom, it worked fine then suddenly it is back again when I switch the screen off, or automatically it is switched off, the backlight slider I find it at the lowest end.
Why thus is happening, it’s driving me crazy, please help me
yeah me too want to know solution for this too ?

[Q] Brightness problems on Defy

I have recently flashed 2.3.6 retail sbf on a DEFY with green lens the main problem is that the screen brightness. On the start the phone as good bright atfer a seconds it dim to a point, that is not possible to see in dayligth, even with pacth, ledefy, diferent Rom nothing change.
If i change the brigth level on the setting it never do nothing, always the same brigth.
I have the same issue on updating to 2.3.6. Screen starts up OK but during book after the Motorola logo starts to animate I almost completely lose brightness. The brightness could be adjusted but seems to go no higher than 50%. I'v tried numerous apps but nothing gets the brightness higher.
I've now managed to root and install Quarx 10th July nightly ICS and it works great, however here is where it gets really weird - if i load the power widget and change the screen brightness with it it actually changes the brightness of the soft buttons and nothing happens on the display.
Anyone have ANY ideas?

[Q] Galaxy S4 I9500 Screen flickering problem

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 ...

Low backlight

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.
