how to deal with screen flicker ? - Galaxy S III Q&A, Help & Troubleshooting

Hi. i have my GS3 for a while now and i just noticed that if i am loading a page on the internet, my screen flicker on the white page till the page loads regardless of what is the brightness.
i figured my GS3 has a problem with white color " hardware issue "
so i downloaded many screen test apps that display full colors. and my screen didnt flicker displaying any.
so i came to notice my ficker only happens when the phone is busy loading something.
i tried to tick the option in the developers option for the screen overlay ? it did nothing .
can anyone help ? figure out what is the issue ? i really dont think its a hardware issue.
i tried different roms but no luck :/
+rep for helps and suggestions. ty

so ehm. am i the only one ? lol sheesh

Can't say I've noticed any screen flickering, but then I use dolphin browser.

ive noticed this the last week or so but not on the white page. Its flickering a little when i go into the bookmarks page. Dont know whats causing it, never used to happen.

Is it real flicker or more like black boxes appearing all over the screen?
If the latter, make sure neither your Cpu nor Gpu is overclocked or undervolted since the issue usually arises with Gpu calculation errors due to overheating (improbable) or voltage problems

Dude, its most likely an incompatibility issue with the custom rom ( am i right? ) you are using. I had the exact same issue with the dolphin browser on paranoidandroid rom. Just install chrome, it most likely is compatible with most of the roms out there.

Touch Screen Issues

Sometimes my touchscreen will be terrible, their will be no response at all.. and it will grab, but it will be in the wrong places, ive only found this problem whenever i rooted and reflashed with das bamf so far, and it blows because its literally the only problem i have now after being so happy with this root/rom deal so far.. i never flashed a kernal, so would that have something to do with it, or are kernals necessary to do? i have no idea what one even is to begin with so if that will improve the keyboard and or permit it from failing that would be worth looking into.. or is their a way to increase sensitivity on the phone somehow?
Thanks!
It's not going to be a kernel issue. Kernels do effect how some things work, but the Bamf team pair their roms with a kernel they find most suitable with their work. Kernels are mostly for setting CPU speed and Voltages.
I don't think your issue is a rom/kernel related issue. Does this problem persist when you turn off the screen and turn it back on? Sometimes if you get sweat or moisture on the screen, it tends to freak out. Another thing you can try doing is just reflashing your rom. I remember putting the leaked OTA Gingerbread on my ex's Droid X and after 2 weeks, the screen started selected itself dead center of the screen. Reflashed the rom, and it hasn't done it since.
If all of these things fail, than you have a hardware issue I presume. I wish you luck
Does your problem occur consistently all the time, or only in certain situations?
I.e: When the screen has been off? When exiting certain apps, etc?
If it only happens in certain situations, it may be a clocking issue that is causing the "lag" response.
The only way ive found to fix it so far has been to wipe the screen down every time before use, but i find that odd because with the factory rom back when i never had to.. so i guess its just more suspectable to elememts interfearing with the actual screen.. i havent changed screen protectors or anything.. The craziest thing to me so far..
Which version of DasBAMF are you running? I have a similar problem with their Sense 3.0 roms. The buttons on the MLB at bat widget and the refresh button for the Pulse news widget seem to work only intermittently.

The problems with your widgets may be related to the resizing issues with the 3.0 rom and where on the screen you have to tap for it to recognize the tap. I think many have been fixed, but there may be still some odd ones here and there.

I was pointing out an issue with widgets on Das BAMF 3.0 as a specific example of an issue you might have. This point is not relevant since you are running 2.1.

On RC5, the 2 widgets I mentioned are still wonky. I'm sticking with 2.1 remix for now.
Do you have any kind of screen protector? I get that from time to time when my screen is dirty and as you said wiping it down has always fixed it.

Yeah, do screen protectors fade over time? as stupid as that sounds ive had this one on my phone for six months.. is it starting to break down or something?
also my next theory is temperature.. when my phone is exposed to hot areas it doesnt react.. i noticed that tonight

Anyone noticed any screen tearing issues

I've only noticed this since about a week.
Its most prominent when I'm in text based apps - Pulse/Verge/Kindle - with a lot of white background.
To describe it - its like a 3mm thick 'glitch', appears for hardly a few milliseconds - just enough to be noticeable.
Its always along the length of the device, and does not matter what orientation I'm holding it in.
I felt it happened more often with auto-brightness but that feeling may just be a dud.
The recurrence is quite random, but I can easily see it if I stare at the screen for even a minute.
Finally I've never noticed it in games or on home screens - not sure if thats just because I miss it in those or otherwise..
I noticed this yesterday for the first time when reading some text. It was very distracting, hoping it was a fluke deal.
Seconding this. I don't have auto-brightness, but I notice it. Definitely happens when reading text with a white background - so get it pretty often in RSS readers, rarely in gmail, and never in games / movies.
Thanks for the replies..
I also noticed this never happens in gmail or currents. Looks like Google-supplied apps run fine...
This leads me to believe that these other apps are doing something wrong, maybe overflowing buffers due to the massive resolution as someone else projected in another thread...
Have you guys played with either the "Disable HW Overlays" or "Force GPU rendering" settings to see if they impact this issue one way or another?

I second this idea.. please try and report the results.
Since my last soft-reboot, I've yet to see ant tearing. However I'll try those options if I see it happening again. Thanks for the suggestions. Maybe some of the others seeing this can try those tweaks?
Happens to me no matter what app I'm running and has been happening since I got my nexus. Even just happened in the app drawer. I will check the force gpu settings and get back to you.

Force GPU rendering changed nothing for me. Still got the screen tearing. I'm going to try the Disable HW overlays for a while now.

[Q] Flickering Multicolored Lines

For the past week or so my phone has had flickering multicolored lines flash across the homescreen(s)/lockscreen when I turn the display back on. Sometimes it will also happen if I'm sitting on the homescreen with the display already on.
Here is my Rom history as the problem began:
Was on supernexus (Android 4.2.2 I believe) - issue was not present
Flashed Unofficial Slim build 6 (wiped cache/dalvik/factory reset before install)- started having the issue
Flashed Unofficial Slim build 6.2 (wiped cache/dalvik)- issue still present
Flashed AOCP 5.7 yesterday (wiped cache/dalvik/factory reset and formatted internal SD)- thought issue was gone, but it started happening again today.
I tried taking screenshots but the issue disappears as soon as I press the volume+power button to take the screenshot. This only seems to happen when I'm on the homescreen/lockscreen, I dont think it has happened while in any other apps.
I'm wondering if this might be an issue with the specific version of the Nova launcher, as I believe that is the common denominator between these Roms (isn't AOCPs launcher based on CM's nova?). I just installed go launcher and the problem seems to be gone (for now).
Has anyone else seen something like this? I apologize if this has been discussed somewhere, I spent several hours searching Google and XDA before posting. I can post a picture later when I have access to another camera phone.
Same issue here
I have the same issue at the lock screen. Prevalent on all JB roms I have tried, carbon, revolt & slim bean.
I'm currently using Carbon nightly. I have not seen a fix for this yet. I have heard it might be an issue with the processor waking up from sleep.
After installing Go Launcher Ex opening it a couple times and then going back to using the Aspire launcher that came with AOCP, I haven't had this issue again all afternoon. Didn't have it at all yesterday though, so it might come back.
I played around with all the brightness settings but it didn't seem to do anything. Do you happen to have any pictures of the effect you are getting? I'll try and post a picture of mine tonight if it happens again. Thanks!
About 3 hours ago, I changed some GPU & lock screen settings and the issue has not reappeared.
I will post back either later tonight or tomorrow morning with some info.
I haven't taken any photos of the problem yet. By the way, do you usually experience the issue on lock screen coming from a screen off state?
ditto on this. I have Cyanogenmod 10.1 installed and I get these lines intermittently.
Try turning off CRT animations and disable hw overlays.

disabling hardware overlays always fixes it for me

Go to settings, developer options scroll half way down and you will find it. You will have to disable it every time you reboot or you can use two paid apps from the market. These apps are tasker and secure setting they are both worth every cent.

Do you have any backlight handling apps? I used lux all the time and it stopped after I disabled it.

Just enabled "Disabled HW overlay" and "Force GPU rendering". Like some of the users suggested, I found about the possible solution from this video:
http://www.youtube.com/watch?v=yhhPPke_Nbw
(go to 1:40)
I usually get the flickering with the lock screen (I use WidgetLocker Lockscreen). I was having some flickering this morning and checking both of those options seemed to immediately cut out the flickering.
I ran across it(the flickering lines) on one of the 4.2.2 roms, can't remember exactly which one but what I ended up having to do was disable one of the tweak apps it came with and install Trickster Mod only. Worked for me, no more flickering or rebooting, not sure what the cause may have been but have had no other issues after that for I believe it was 2 weeks
Please elaborate

By chance can you give some more details about this Trickster Mod like where to find it and what it is supposed to do?
A link to a thread would be great

Scroll down to my post there. If you still need help, just let me know.
Trickster mod I believe is mainly for Rom's that have Kernels that can be OC'd or Under Clocked. Kind of the same as Android Tweaker or SetCPU but is a little smoother for me IMO.

Screen flickering while typing

I just noticed last night that when composing a text message, my screen will flicker slightly, like a variation in the brightness every time i press a letter. I'm not sure if this is a sign of a hardware failure about to happen or what, but i'm wondering if anyone else has experienced this? It's not a major issue it just irritates me a little. I use auto brightness but it happens even with it off. I searched the forums and nothing came up so hopefully there isn't something that I couldn't find.

Could be a few things..
Are you on a custom ROM?
Custom Kernel?
Just need a bit more info

I'm using the latest hyperdrive. I checked the known issues and it's not listed there. Doesn't mean that's not the culprit. I don't know the name of the kernel but it's the default option when installing the rom, not ktoonez. I really hope it's not a hardware problem because it will likely get worse

I'd just try another ROM and see how it looks. Sounds like it could also be the kernel or just something not jiving with the ROM.

I believe I have found a fix for this issue, go to settings>my device>display and then scroll down until you see the "Auto adjust screen tone" option and un-tick the box. Hope this helps!
