Screen flicker - Galaxy S 5 Q&A, Help & Troubleshooting

Ok guys so i have this problem that started occuring only a couple days ago. Before that ive had no problems with my phone, but now when i turn the screen off/on it flickers green-yellow-ish. This has so far only happened when turning the screen on/off. It doesnt happen all the time though, it comes and goes. Any ideas? Has this happened to any of you? Thanks in advance

Hello, I would be happy to help you but have the same issue.
You can try anyway to disable all automatic screen luminosity settings and try to change luminosity.
It's not a fix, only a workaround.

Running a screen filter at lowest settings could help. Or using lux app to change the automatic brightness to pass beyond troubled screen brightness may help. Only ideas if factory reset doesn't help. It's a hardware issue otherwise.

Auto-brightness problem...

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.

Auto-brightness problem, anyone experience it ?

Hi,
I have an auto-brightness issue, when I turn the auto mod on the screen turn all black. I can still heard clicking sounds and when I put the N7 under a strong light ( white leds ) it turn on. So it is definitely a brightness problem. I just fix the level on 25% and everything go right, until I start the YouTube app who magically change the brightness and in the first 5sec of the video the screen turn black again I have to fix the value at 50% for avoiding that.
Anyone experience this issue ?
Any fixe ?
Do you think it's an ardware or software problem?
Thanks

[Solved] Brightness dims very dark every wake?

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!

[Q] Displaying dimming...

My display will dim down to half of the brightness it was set at and will not brighten back up. To get it to brighten back up I either have to turn the display off and back on or touch the brightness slider. Any ideas on how to get this to stop? Display is set to standard, Adapt display is unchecked. Everything is turn off with Smart Screen. Auto Brightness is unchecked. I am running NC2
This is super annoying!
Happens to me too. I also am not able to turn off or restart my phone. It gets to a point where the menu button and back button are lit up and the blue led is lit at the top with a black screen but stays that way until i do a battery pull. All this started after going to nc2. Tried different roms and didnt change a thing.

[Problem] Screen flashes bright on touch

Hello everybody,
I have this problem since few months:
Sometimes out of nowhere the screen starts flashing (like turning up brightness to 100%) for a split second when I touch it. After a while it stops. I have no idea where it comes from or how to replicate it. Sometimes restarting the device helps, sometimes not.
Automatic brightness is turned off.
Can anyone think of the origin of this problem or how to solve it?
It is a A2017G and on 7.1.1 with A2017GV1.2.0B05 but was the same with the last update (B04?).
Anything I could think of would be SystemUI Tuner, but I only use it to hide the NFC icon.
Thanks!
