Flickering screen only when playing videos - Galaxy S 4 Q&A, Help & Troubleshooting

Hello everyone,
I have my i9500 for about a year and had no problems until now ... the problem started around two weeks ago. whenever i play a video (it happens on any player including youtube app) the screen starts flickering (it never flickers when you do anything else!). I wanted to know if anyone has seen this and if there is a fix for it.
thank you for anyone who can help

I have seen it before and reboot the phone fix the problem.

Go to Settings, More tab, Developer options (if it's not enabled please google how to enable), Force GPU rendering
I found this fixed it in my S4 Black edition.
If this solution doesn't work for you then also try to clear the cache partion.
To do this, Hold power, home and volume up until the phone shows [Samsung Galaxy I9500 blah] then release only power button. you are now in recovery mode. use volume buttons to scroll to the correct option (clear cache partition, i think) and press power to select it.
Then reboot. Hopefully this will work for everyone.

Fix for screen flickering upon video playing
I just got a brand new s4 i9500. And when I play videos from YouTube, whatsapp through Samsung player or vlc etc my screen starts flickering like crazy and then blacks out.
To fix I went to developer settings and enabled a function called " Turn off hardware overlays"
This instantly solved the problem of the flashing screen during video playing.
Hope this helps.

[Q] Last attempt, upgraded to GB, screen locked dim after first shut off.

I upgraded to synergy's Gingerbread rom and everything went well, I turned off the screen then turned it back on and the screen is stuck on dim (like 20%) and cannot be adjusted. I switched to another GB rom and its the same. I updated the kernel like someone said to 2.6.35.10-htc-kernal_and18-2-signed after updating to gingerbread but it didnt fix the screen brightness issue, Im stuck at like 20% still and cant adjust it with any settings or programs.
Any help?
Is my phone just koo koo pants or has this never happened to anyone else? Or is this one of those problems everyone knows about so they ignore new posts about it
Are you on RC1 or RC2?
RC2 has an "auto-brightness" under the quick settings menu.
You can also go to menu --> settings --> display --> brightness, and make sure that auto brightness is unchecked
Or... All apps, open up spare parts, and there is another brightness mode option there.
I dont believe I remember how to check RC1 or RC2, my hardware version is 0003?
And I tried all settings and none worked, auto brightness is unchecked.
Well RC1 was released a few weeks ago, and RC2 was released yesterday.
When you installed synergy, did you wipe cache and dalvick cache?

Then it must be RC1 because this was last week and yes I do a dalvick whipe as well as full reset.
Ill go grab RC2 and check it out.
Thanks for the help buddy.

Try wiping system and boot as well. This may be caused from "left over" system files from your previous roms... I use VR super wipe and do the factory reset and wipe dalvik and cache every time.

I had that same problem on my LG Optimus S when I had it.. I ended up having to unroot and factory reset it.. fixed the problem. then re-rooted and installed all types of Roms and they worked great there after.. now im stuck with this unrooted Evo
Just wondering, has anyone had problems with their media volume staying at the same volume, no matter if you turn it down. This is really frustrating, I have tried flashing my recovery and deleting the stock car panel app (which.i hear causes the problem) please can someone help me. I'm running synergy rc2.
Sent from my PC36100 using XDA App
I already had done a full whipe when I installed and Ill try unrooting and going to GB stock, if the screen doesnt work Ill just have to go to the sprint store and get a new phone and wait for GB to be jailbroken which I have every confidence will be sometime soon.
well I unrooted and went to 2.3.3 stock and it still dims the screen after the first shut off. I have to take it to the sprint store now to get fixed but I just had my wisdom teeth removed so I cant go anywhere for a while. yay

Camera inverted (upside down) with CM7.

Hey guys.
I've been using CM7 for about a month now, currently in the 010911 Nightly.
Everthing was fine until this past week, when the camera of my phone started to have strange freezes and lags. Then, one time, it FCed and when I turned it back on, the display was inverted, and colors were all strange and washed off.
I've rebooted, cleaned the data, etc, etc, and nothing fix the issue. Keep in mind that there's nothing with the tilt sensor. It's something software related.
I remember seeing a fix for a similar problem a while back, but I searched this hole forum and couldn't find anything, so, I beg for your help.
Thanks a lot!
Sorry for the bump, guys. But I really need some light with this problems.
Try clearing Camera app data or switch to another nightly.

Thanks for the reply.
Unfortunately, I already tried both things you suggested, with no luck.
Not sure if it has anything to do with it, but is the boot mode set to 2nd init by default ?!
You can also try using other camera apps like Vignette.
Sent from my MB525 using Tapatalk
dude, we are on the same boat. Tell me when u find a solution.
A temporary fix which i m not sure till when its gonna last but is working for the moment.
open camera, leave it opened and pull the battery. put the battery again after 2 mins and see if it helps you. Its working for me at the moment but dont know the logic behind the process.
I already got my camera hardware replaced but this problem happened again just after rooting the phone.
I have the same problem and I'm almost sure it is a hardware failure. Maybe after a shock or drop. I'll open my unit this week and see what's wrong. Did some of you manage to fix it?
I've even tried flashing full stock sbf without success, so I'd blame the camera module.

Mine also continually freezes
the reboots after about 5 secs. This is a hardware fault not software as I have tried many full wipes & different roms

If you have done a factory reset, wipe cache etc then it must be hardware so, yes you will have to send it back. Unfortunately I can't send mine back because it has been rooted & there is no way to reset the binary counter at the moment on mu I9500

This is the first time I've tried aokp and I have to say firstly thank you for trying to port it for the s3 mini gang
I like the options, it's very customizable!
Unfortunately I have to make a few pointers about stuff that annoys me
- the graphic tearing/glitching is really bad..
- where's the file manager??
- no performance settings..
- some aokp rom settings are glitchy.. Such as navbar wouldn't disable after I enabled it. Center click was invisible. Meh.
- quick settings button in status bar does nothing, neither does pulling down the right side of the status bar (basically no quick settings tiles)
- I suck at posts like this. Meh.
Ok ok I'm sorry for complaining. I'm very happy with the progress of Cm10.1 which is what I'm using now. Thank you for all your hard work.
May the force be with you. :what::beer:

Hey you can bring cpu to normal by turning off gps, wifi and data then rebooting. Turn it all back on after.
Do you get graphic glitching in menus? Thanks.

Smooth and stable ROM, still has the 1000mhz bug when rebooting with wifi ON and gps OFF. Just need to have gps activated all the time. Camera flash options still inverted.
Lots of customizations available. Confirmed that bluetooth doesn't work well. Tried to transfer an image file via bluetooth- even when paired, always fails.
(Temp fix) I copied the files from CM 10.1 (/system/etc/bluetooth) to that of AOKP, after setting permissions and reboot, was able to have successful bluetooth transfer.
Over all great ROM.

[Q] Galaxy S4 Constantly Restarts

Bit of an annoying problem, my Samsung Galaxy S4 i9505 (Rooted) constantly restarts at random now and again, and it can be very frustrating.
Also, I have the app 'App Master', which when the phone is restarted it shows the boot up time. When my phone randomly restarts, the boot up time could literally say it took hours (It's went as high as 40 hours... not sure if this is relevant or will help but yea...)
Also I get logged out of everything (facebook, twitter...) whenever my phone restarts which is very annoying.
Any help would be appreciated, thanks!

See if the same happens in download mode too.
If yes..you have a stuck power button.
If no, have you removed all the knox related apps? they cause this too. Deknox your phone.
If still persists, data wipe or flash stock rom..disable knox first via recovery..then proceed with normal rooting..

Yeah. Knox is the culprit then.
Check the i9505 rooting methods and if any deknox script is there.
Or simply if you are rooted..install the "system app uninstaller" app from the play store..(a red recycle bin logo app) and delete all knox content.
Bdw you wont be able to use knox anyway if you have a knox trigger

Very true, I think it's unusable anyway being triggered during tampering
I've removed everything related to knox so hopefully that fixes it

Screen not being usable is the issue of the charger. Try changing the data cable.
Restarting issue could've been linked to a partial stuck power button or maybe because of an improper way of flashing or improper way of flashing kernels
Bdw did you change it or get it changed.?

Ohh.
Now it is kinda certain that the way you changed or got the charging jack changed has a problem.
Try reassembling the charging port
This can be of great help.

Hello, it's a weird case.
Try to download the latest firmware available and update through Odin, then install a custom ROM (to fast de-Knox). Install CM11 M9 and leave original kernel, let your battery discharge until power off, connect to the charger and power on. Don't use it, see if charger more than 80% without reboots
