Hi,
I've a strange and creepy problem on my prime, sometime the screen and speaker (tablet) show some static interferences, the screen messed up display horizontal bars white (in landscape ) and noisy cracking sound.
When it appends, I reboot the tablet, and the problem is gone.
I already tried a factory reset, but the problem is still here, occasonial but still here.
I am on last stock firmware. I've got the plan to root my prime, but it need to go RMA, I prefer to rid of this problem before.
Did someone encounter this bug before?
Thanks.
If it's only on the left side about an inch, then it is a known issue a lot of us have. I haven't had static in sound.
Well, no it's horizontal "static" bars wich appear randomly on all screen surface, next time i'll try to record it with my phone camera.
Something like that:

but far worst in my opinion. It's like flickering to me.

That's pretty similar to what I have, but usually it goes from the bottom all the way to the top of the screen, but only on the left side while in landscape position. It goes away if I move the screen from landscape to portrait, or reboot. Sometimes just locking and unlocking is enough to fix it. It was really bad when I was running motley's kernal 3.07 and interactive governor.
Now I don't have it as bad, I'm using Motley's lite kernal, with SIO, Ondemand, and sql patch. All I get now is a flickering lower bar and sometimes the left side corruption, but locking and unlocking screen usually fixes it.
If you'e getting this all over the screen, then that's something different and an RMA might fix it. If you're in the states, some best buys are replacing them with a 700, which is likely better.
I have gone from my first amoled screen phone a galaxy s2 to s3, I gave my wife the s2 so I can hold the two sides by side and wave the phones side to side while holding my eyes still and I clearly notice the s2 screen drawing a solid light while the s3 looks like the screen is turning on and off at a very high speed, like if your using an old crt with 60hz.
Anyone else noticed this?
I imagine because generally speaking its not noticeable most of the time unless shake your eyes or shake the phone its a battery saving feature.
If power saving mode is active on your S3: turn it off
Custom rom, not using Samsung firmware. I have looked at my work mates s3 and it has this crt like flicker to, he has stock rom... And he won't let me root and custom rom his phone lol.
Chercked my S3 to see if it did this and it doesn't, no flicker at all but I don't have any motion settings turned on apart from rotate and no battery saving modes, maybe one of them is causing it.
As for what you cna do with your eyes, holding them and shaking them, now that's cool.
sorry for the bump...
But Im having this issue too. Its my 2nd s3 (first one had a yellow tint to it and I couldnt ignore it once I saw it) and my screen also flickers just like an old CRT at 60hz. The one with the yellow tint didnt seem to have this problem but I wasnt sure if it was how the screen was supposed to look when fully functional or if my eyes were going (pushing 30 lol).
Ive tried a factory reset. Ive tried checking Force GPU Rendering in 2D option. Ive tried a custom kernel and ROM. Im not sure what else to try!
I have the same issue with my galaxy note 2. But I don't find any solution to solve that yet
Has anyone else had issues with their back light faulting? I've searched and have seen that other sprint evo lte users have had issues with screen flickering, but my problem seems to be more serious that that. when i wake up in the morning the screen is blank. thank god i have a custrom rom installed and can manually mess with the status bar slider to get the backlight to turn back on. It just needs to be tweaked here and there. the backlight seems to only like to work on full brightness, if not, it will flicker like crazy. if i press with more pressure on certain parts of the screen the backlight turns off completely until i remove my finger. I dont think its a proximity issue since it'll just flicker sitting on a desk. Do I need to replace the screen? is this worth it? i havent dropped to phone or anything for this to default. I can upload a video later. gonna use my OG evo for that which is still kicken by the way
I realize this thread is incredibly old, but did you ever find a solution to the flickering problem? I just started seeing the exact same behavior, including the screen going dark when putting pressure on certain areas of the screen.
Thanks!
I have a PJ75100 doing this, but the screen does not function at all. I get the orange/green light while charging, and if I power it on it acts as if it's doing it's regular startup, but nothing shows on screen.
I did update the stock firmware with the latest release ruu, but still no screen.
I'd really like to get this one going as it's not the normal Jewel, it's the white and silver one, and my girlfriend wants it to replace her iPhone 5c.

Not only do I have light bleed but I'm also seeing screen flicker. I really want to keep this device but I'm getting sick of this...
The first thing I noticed when I turned on the device was the light bleed. Its pretty bad, and I normally don't mind those types of things. No flicker here though.

I noticed if I turn up the brightness it goes away.
I don't have light bleed, but I do see flicker if the screen brightness is turned down. It's reminiscent of the original Nexus 7, which had the exact same problem.
I have the flickering too...really annoying. I was hoping that this would replace my iPad but it's not looking good. Although lollipop is pretty amazing so far.
Does it only happen you adjust the brightness? If so, i dont think its a big deal as long as it doesnt happen during actual usage.
I noticed the flicker issue when I first was using it. I then turned off auto brightness from the main settings and started using Lux Auto Brightness and the issue has been resolved as far as I can see. I suspect this is an issue with the Lollipop build's brightness manager and not a hardware issue from the backlight. Also as far as bleed goes, there is apparent bleed when viewing the screen at an angle and looking directly at the edge, however I have found that it is a complete non issue in normal use (even in a fully dark room), which stands in stark contrast to my Nexus 10 which has noticeable edge bleed when viewed straight on.
No Flicking here
No flickering here either.
No flickering, but the auto brightness is very weird! It goes from extremely bright to extremely dark without me actually moving, same light conditions?
No flicker here!
Well, I guess we can all admit screen flicker is of the norm of Tegra.
Im seeing flikkering too.....
Only when brightness is low.
Remind me why Google/htc did not decide to use a 64 bit Qualcomm processor instead? :-\
Do you think that this issue can be solved via software update, or is this issue hardware related, and therefore cannot be fixed easily

considering that not everyone has it
So i say no
This issue seems to be related to auto brightness/adaptive brightness: The same brightness level set manually doesn't flicker.
Seems to be a software issue to me, and it seems highly likely every Nexus 9 flickers with auto brightness on (and at low relative brightness setting) in low light environments.

But, my screen flickers when I am on a constant brightness level. But, it doesn't show up as much when the screen is on at full brightness, just when the screen is at half brightness or just below half.

I guess we aren't experiencing the same issue, then: My screen only flickers with adaptive brightness enabled in low light conditions, seems like it is constantly readjusting the screen between two brightness values.
My Nexus 9 doesn't flicker at any constant brightness setting.
Yep, my Nexus 9 flickers as well.
About 15-20% brightness (fixed). It doesn't flicker all the time and it goes away if you change the brightness level or even by itself if you change the app you are using.
This leads me to believe this might be a software issue (N7/2013 had this too when it came out).
Seems that a lot of people complain about this bug/glitch. It mostly happens with this device, specific to some carrier like s5 t mobile etc. Mostly what people face is flickering with a green/yellow nuance that covers at least half of the screen, and that happens when you set screen brightness on minimum. Some other ( like me ) also get the flickering while turning the screen on or off. So I started doing some searches over the web, and tried all the 'fixes' possible. Sadly to me nothing worked. Some of these 'fixes' are :
Turning off auto brightness.
Turning off adaptive display.
Turning off screen overlay ( found on developer settings )
Also other strange ones like removing your sd card etc. Few people say that these worked for them, but for me it didn't.
I tried booting on safe mode, and the problem was still there. I also flashed official 5.0 and the same. So the only thing left was to blame the hardware. But I was sceptical about this since the problem is not persistive, sometimes it happens, sometimes not. Sometimes it happens on small scale, sometimes it is worse. Also a lot of people say that their devices were working fine and the problem started after marshmallow update. A certain person on an online forum claims that he/ she spoke with samsung officials and they are aware about this problem and working on an update to fix this. Does this mean it is not physical problem but just a software glitch ? Hard to say, I sent my phone to different local repair shop and they say it is screen physical problem. But maybe they just want to scam me and take money ( new screen costs too much )
After going through all these, I just got the idea to try and flash an older firmware, like kitkat. And to my surprise, on official kitkat rom it still does the problem, but FAR less.
So TLDR if you have this glitch and gave up on all the 'fixes' you found online, try flashing kitkat, it might work for you even if it's not a permanent fix.
I'm sorry to bump this topic being that it seems dead. However after my own research and now my second S5 from T-Mobile. I'm at the same point as you. My research states that it's more of an AMOLED screen issue, which after a factory reset and flash of older ROM and such does make sense. However, at the same time it could be an actual issue with the screen.
It's definitely a hardware issue in my case-cold temperatures exacerbate it ie-I have no flicker issues in the summer, but get flicker issues in the winter if my phone cool's down to the 60s. The flicker goes away if I heat the screen.
It seems the lower the temp, the more wattage (brightness) is required for the display matrix to function; insufficient wattage/heat when the screen is activated, and the matrix collapses. This is why it autobrightness tends causes issues when it provides power below threshold for matrix stability.
Easiest legitimate econimical fix is ordering a replacement screen, if you have reaervations about yiur shop doing it, it's a very easy/cheap/simple process to do yourself and plenty of how to YouTube videos.
okay, I will solve this issue for yall. I have an s5 g900t that had the screen flicker issue and also when temps are cold, the screen would blank out till I warmed the screen. I fixed this issue after a year of having the issue. a temp fix which can damage the device was found by accident when I went to change out a broken rear cam. heating the screen with a heat gun during surgery fixed the issue for a while then the symptoms came back. after much much research and testing, I found the amoled screen was the culprit. I ordered a new screen and replaced it. no more issues. I took the old screen and replaced it to my other s5 which is for testing only and the screen flickered under low light and would not come on when cold. so, if you have a screen that is flickering in low light and/or wont come on during cold, its your screen. replace it and fixed. how long the new screen will last? well 2 years later no problems, yet.
FYI, AMOLED screens are notorious for this issue and the manufacture is well aware.
