I dropped my phone the other day, now unable to change the backlight setting. I've done a hard reset with no resolution.
It's stuck at the absolute 'darkest' brightness.
Any ideas?
Thanks!
if the backlight is not functioning at all, you may have actually broken that part of your phone. if it is always just dim, i do not know what to say. sorry. hard reset should have fixed it
[edit] just saw this, may be of use but i didnt check it out yet: http://forum.xda-developers.com/showpost.php?p=12764694&postcount=6
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?
Ever since as long as I can remember, my phones brightness will dim to a brightness so dark you just can't see it. Even if you manually set the brightness, once you lock and wake the screen, it's fine then suddenly switches to dark.
I've used multiple ROMs and they all do it. Is it a device issue, or could it be a kernel issue? I've not screwed with kernels so I don't know if it could be it. If it's a device issue, I'll be getting a replacement ASAP.
Any help is appreciated!
Now that I'm able to Google, I realize it's a common problem with the S4.

The only time I had the screen go dim like you describe is I remember once following a phone call. It goes dark when you put the handset to your ear like it's supposed to, and lights back up when I pull it away from my head. I was stepping out of a truck into the broad daylight when I tried to hang up my phone, I couldn't see the screen very well. The other party ended the call, and my screen timed out while I was squinting at it. I pushed the home button and it lit right back up nice.
You got something going on, and if you tried all those different roms, say... can you nandroid back to stock? Did you try that?
I'd try everything I could on the outside chance of repair instead of replacement. If you get a replacement you might be stuck with that MF3 where you cannot install a custom recovery.

Mf3? Is that something new with the S4s to prevent custom ROMs?
It does not go pitch black. It goes very dim every time I wake the device. If you Google S4 screen dimming it's a wide problem.
Once you wake it, it's fine for 2 seconds and dims quite dark. It is not screen timeout/sleep/etc since I can still see the screen.

I'm on MDJ and don't get any auto dimming of any sorts. Auto brightness is off, brightness controls about 1/3 brightness (indoors), but Power Saving mode is on with all three options on.
My S4 is MDL. I found out the problem (More than likely) was the Paranoid Android ROM. I was on ver. 3.69 and since switched to CM 10.2 Nightlies, latest as of today, and no screen dimming. I will install my usual apps and use it as normal and if it happens, it's probably an app. However, the only apps I use are ones such as SwiftKey, LightFlow, ASTRO, Chrome, and Dashclock.
I'm on stock MDL. It has only been occurring since I upgraded from MDB 3 days ago, and is a huge PITA because brightness controls are unresponsive during this time - I go into settings to adjust brightness since I have removed all the brightness controls from the notification panel as they've always worked just fine, and turn off auto brightness, scale it all the way to max, and it is still dim as crap.... Only fix I've seen is to reboot, which is obviously not ideal in most situations when I need to wake the device! I'm using STOCK kernel, STOCK ODEXED ROM as well, nothing crazy should be going on to screw with brightness settings being unresponsive either!

Do you by chance use Light Flow?
I solved the problem. I had "lcd_backlight" control flipped on in the settings of Light Flow. It fixed it. To tell if it's an app problem, just factory reset and try, once you boot up, to lock and wake the device to see if it happens. If it doesn't, it's an app problem more than likely, or even a general setting. Troubleshoot for the win!

I do use Light Flow, but I don't have either one of the LCD Backlight controls enabled, never have and never will, so I don't know how that could be affecting my phone at all.... That's a good start for some, but not for me, unfortunately! Good catch though

I had this issue before on my Galaxy S3. I ended up replacing the front glass because of a dead pixel. Come to find out I had a sensor issue and that was causing my brightness auto going to whatever level it wanted.
Perhaps you're experiencing that too. Haven't heard or read of any sensor issues yet with the S4 but you could be the lucky winner!
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 ...
Screen started flickering out of the blue when I took it out of my pocket. Its on all colours and background except for black. I have tried factory resetting the phone but still no luck. However the phone dosen't show any flickr at lowest brightness setting. Any help would really be appreciated.
