    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.

    If you are rooted and kit kat you have the ability to screen record. I would try and disable juice defender and consider uninstalling just to see if may be something to do with it. I also would consider wiping cache and davlik cache in recovery. May not resolve but at least give you something else to try.

    Thank you chad, I recorded the activity with the app Rec. but in the video everything seems normal, it does not record the problem (I don't know if that means something).

    I just Freezed JuiceDefender wiht Titanium Backup, it is the same, however, I meant that controlling the brightness with Juicedefender and NOT the stock Settings, actually solves the problem, if I lower the brightness inside JuiceDefender the screen does not flicker.

    I had wiped the the Cache partition and the Dalvik cache in CWM before, nothing...

    The problem looks a bit like this (although not with those divisions in the screen, only the flickering, blinking, I don't know...

    I would try to flash a custom rom or find the stock firmware for the bootloader and baseband that you are using and try to flash via recovery or Odin depending on whichever way you go. Hate to say it but it almost sounds hardware related.

    Thanks again chad, I'll try that soon, I didn't wanted to wipe my data but I think it is the last thing to try. The thing is, which hardware, because it could be the mobo, or GPU, not the LCD, I'm afraid to take it to a local technician and that they charge me for the screen and the problem continues, the screen alone is like half the value of the phone, I'm in Venezuela, so there is not a lot of options as service centers go.

    I think after wiping my data I'll try to open the phone myself with some Youtube video's help and check the connections to the display, or try to sell it like this at a discount, it works after all, and it is rooted, I guess it raises the value a bit..

    i have a similar issue once the brightness is on low. I was told its a OS issue. So i'm hoping someone that has the issue can flash their phone and then upgrade to see if that will fix the issue.

    I have the same issue out of the blue. Only on the lowest brighness setting and when the phone dims on it's own before the screen shuts off.

    I can use any dimming app and it works just fine.

    I've tried all of the above suggestions plus taking the phone apart to check all of the internal connections. No luck.

    Running 4.4.2 non rooted on a Telus S4.

    flickering problem can be solved easily.Just turn off the "AIR VIEW" feature of your mobile....

    Air view solves nothing. I've wiped twice and moved to Cyanogenmod 11 and the problem persists. It a hardware issue. Would love to figure out how to fix it if it's a bad connection or something simple.

    Hey guys. I have the same problem and it is really driving me crazy. I would throw the phone to the wall if I could afford a good one. Did anyone solved the problem? Please let me know.

    Turning off Airview doesn't fix it if Airview isn't on. However, if you turn on Airview, and then off, that does fix it. Just a little added detail for those not using Airview and discounting that option without trying.

    This happened randomly, KitKat update +6 monthns ago, only change was removal of a launcher (not Lollipop launcher) that was chewing up my battery

    I didn't root my mobile but have the same problem as well. All you have to do is just turn off the power saving mode. It works for me, hope it helps you too.

    Hi,

    I solved it on my phone (S4 with 4.4.3) after searching on internet. with me it was solved very easily:
    Settings - Developer Options - check "Disable Hardware Overlays"

    When I read about it I suddenly realized I had been messing with the settings because of some advice on a a board "how to optimize your phone". Great proof never to mess around if you don't really know what you 're doing :-)

    Hey all,

    I had done a basic glass repair on the i337 t-mobile Galaxy S4. After cleaning off the glue with some alcohol gently and re-assembling the board back on etc, to make sure the screen was good to go after the repair. When this was all done and it was time to turn it on, it began to flicker and change colors. I tried the auto brightness and unchecked auto tone in settings>display it seemed to have worked for a short period then went back to the same shenanigans. (yes i just said Shenanigans ) I had left it for a little while while doing some research and then came back to it to find it now won't even turn on. When I start the phone up only the LED will light up for a short period of time after the phone vibrates and then will give me one short vibration without the screen starting up and it will repetitively do this without ever turning on.

    If anyone has experienced this it would be a great help to hear your thoughts.

    Lollipop? If lollipop, go to Settings > More > Developer Options > Simulated Color Space > set it to Disabled. And by the flickering, i don't know much about it. I only know by disabling Show Screen Updates at Dev options. EDIT : About the phone won't turn on, might be a screen problem.

    MY PHONE (S4) STILL FLICKERS
    My version is 5.0.1 this only started happening 1.5 months after the update. I tried the air view and power save solutions, the developer options (though i didnt actaully find that in my settings) and I dont know or have "lollipop" or "juice defender"
    My phone slightly flickers when the brightness setting is low (15%) but if i have it high than put it low the screen goes bonkers and flashs green or pink until i turn the screen off and adjust the brightness again....help

    Follow maurits2000 instructions above, but "you have to unlock developer options to see it: Head into the Settings menu. Samsung's done things a little differently and changed the way the settings menu looks, so you'll need to hit the "More" tab. Look for "About device" at the bottom. Tap it. Hop on down to the build number, and tap it seven times. One. Two. Three. Four. Five. Six. You'll get a little prompt saying you're about to unlock the developer settings. Hit that button one final time -- seven! -- and they're unlocked."

    Thanks maurits2000...worked for me!
    Credit for the unlocking goes to Daniel P on another site.
