Brand new V30, just opened yesterday. Everything is running well except for a weird white flicker on the AOD. It's horizontal, from the edge in, about a sixth of the way across the screen. It doesn't flicker when anything else is on the screen but the AOD.
Any ideas?
Here's a video of the issue

Thanks!
I would replace the phone, thats is 100% not normal, i have had my phone for 4 months now and this has never happened to me. Just to rule it out you dont have any screen overlay apps running right,?
edit: also a factory reset wouldn't hurt.
Does this also happen in low brightbess?
Looks similar (just in very very small) like what my display had after i crashed with my bike ?
I forced gpu rendering in developer options and changed the aod display to the normal clock and then back and it seems one of those two things fixed it. will keep an eye on it though.
Came back briefly this morning. will continue to monitor.
I got it on eBay which makes returning/warranty stuff a little more annoying than usual.

so I returned my sgs2 today and got a new one (old one had scratches). Now it seems to me that there is some flickering with black lines (very faded) on certain brightess settings on mainly white sites using a browser.
I noticed the flickering appears around 16% - 19% brightness settings (using "brightness level" from the market).
This flickering only appears only if "auto adjust screen power" is NOT selected, same brightness with it activated shows no flickering.
Also last but not least if plugged in with USB cable the flickering stops as well.
Can anyone re-produce this flickering?
1. Download "brightness level" from market, go between 16% - 19% (try step by step), with me its strongest at 17%.
2. Ensure "auto adjust screen power" is deactivated under Settings>Display
3. Open Internet and just look at a mostly white page
4. Ensure USB is not connected.
Can you see some slight flickering? Lots of lines across the screen?
Wonder if its just me, might go back and return this one tomorrow then
I assume no one suffers from this issue?

No flickering.
I get black/dim horizontal lines flickering on the display at low brightness regardless of my "auto adjust screen power" setting. I'd describe it more as a shimmering of the screen. It's very distracting - I first noticed it whilst trying out the Kindle app and it made it very difficult reading the text.
I believe it's down to interference with some radio component of the phone. I've searched various forums and haven't come across many mentions of this so maybe it's a bad batch and I'm considering returning mine. It's frustratingly variable so I hope I can demonstrate the fault in store...
I'm wondering if the increase in brightness just masks the effect rather than eliminating it. At lower brightness settings, any local differences in brightness are going to be more noticeable.

have you noticed any change at certain battery levels?? Like if the battery was at 90% its easily noticeable, once its like below 70% I'm not able to re-produce it, no matter what I try down to 0%.
So maybe since it seems to be only from 90% - 70%, it could be to do with the current/voltage at certain brightness levels with white background...very unique problem it seems..I'm thinking of going to the o2 store but I most likely wont be able to re-produce it then and there so will they still exchange it? hmmm lets see..

I'll note down what the battery power levels are over the next week or so.
I went into the O2 store after work and reproducing the effect was indeed difficult. I had it showing the effect in the shopping centre whilst sitting down at a bench. I had it showing the effect whilst in the queue to wait for an O2 staff member. Fifteen minutes later, once I'd got to talking to the staff, it worked fine. All I could do was explain the problem and ask if anyone else had reported it. They advised I "kept an eye on it over the next couple of weeks".
Really frustrating. I'd entertain the possibility that my eyes are faulty but I've shown the effect to someone else and they agreed it was distracting.

Hi,
I was not able to reproduce it using your directions, but I have to say that I also noticed horizontal lines flickering on white.
I tried to reproduce it but I can't find out what it is related to.
So it's doig it just in random fashion

does it flicker with auto brightness on? You might want to download an app like "brightness level" and set it to different settings to see when/where it flickers...mine usually flickered at 17% screenbrightness when battery was at 70 - 90%

Yes I did download it and followed yur directions to try to repruce it. But I could not. I set then brightness to various level from 100% down to 0, but no luck. I have to try now when battery is at that level. Then it could be some kind of intereference. Lines I noticed on mine are very subtle and close about 1 mm
Ok, confirmed: 92% battery, brightness 17% on white or close to white screen color, there are horizontal lines like some itnerefernce/noise. Annoying
Samsung galaxy S2 screen flickering
I also have the same screen flickering problem.
it happens when the battery level is around 87-91%
Any soulution?
same here
black lines around text on white background. It disappears after a while, but is really annoying. I suppose the only solution is to change the phone?
sorry guys to hear u got the same problem....I never found a resolution to it apart from returning it to the store....once I managed to reproduce the issue infront of the manager he swapped the phone straight away.
If you got the same issue make sure you get to the store with the battery level and brightness level that shows it up, ask to go into a dark area to show it properly.
First o2 store I went to the guy refused to look at it properly and as it was light outside he couldnt see it anyways. Second o2 store I went to, the manager went downstairs with me and turned off the lights to see the flickering because it shows only on low brightness so make sure you take that into consideration when in a bright/well-lit store.
i have the same problem, it, but it only appears when "auto adjust screen power" is on. Its really a shame! Only way to fix it is to change the phone?
same here. flickers at low brightness with battery under 90%. called samsung hotline. the problem was new to them and the only idea they had was resetting the phone. tried it but unsurprisingly its no help. galaxy s2 could be great but it has just too many annoying hardware flaws
Same problem
Well I noticed this on my SGS 1 !! ... when I have PACKET DATA turned on this flickering starts. It starts really hard when i have this function turned on, but when i disable it there's nothing...
Noticed same problem on SG2 bought in Sweden
Realise this is an older topic but i have recently noticed this issue in low light with Auto On. Battery level at 85 percent. For those that had their phones replaced did the issue continue? Has anyone seen this with the yellow tint also?
Noticing this issue as well on Villain ROM 2.4. Auto brightness enabled and 90% battery.
*Edit* Just did a CWM restore to stock rooted and the flickering seems to have gone. 85% battery, auto brightness enabled.
phone swapped... problem kept
i got my phone replaced 2 months ago and was very happy with the new one since it had no screen flicker... until now. so my current sgs 2 now also suffers from screen flicker and my only options are to send it to samsung and hope to get a replacement or to live with it. and since im beginning to think that this might be a general problem i tend to keep it. although i have to admit that i dont like my sgs2 as much as i did before...
Hi everyone!, I'm having this really odd issue with my S2. I've only had it about a week now and this could have been happening all along though I didn't notice it.
Basically If the screen is off and I hit the power button is has this really slight flicker as the screen comes on. It's almost like a single line down the screen right before the wallpaper appears. It's also right-justified on the screen and always in the same spot.
Has anyone else had this issue? It can be reproduced by simply hitting the power button to shut the screen off then hitting it again to turn it on.
Thanks!
Edit: Also the screen doesn't always fade on. 3/5 times it will just "instant-on" where I'll hit the power button and it will instantly show the lock screen tile instead of "fading" into it. Does this happen to anyone else or does it ALWAYS fade in?
I'm probably just being paranoid but I'd rather replace the phone quickly to avoid actually sending it to manufacturer.
Thanks again!
You should take a video of it so we can see if it is normal. I don't see what you describe, and not sure the phone is supposed to "fade in" to the lock screen. Mine is always instant on.
I once flashed to Litening ROM and it had that flicker (lightning style) as a feature I guess, is it the same problem OP stated?
Regards.
Saw it once two days ago, vertically on the extreme left of the screen. Haven't seen it since, but it was very rapid - blink-and-you'll-miss-it job. Can't say it worries me. On Revolution FWIW.

sorry I can't take a video since this is the only device that I own that is capable of taking video.
anyway, yeah - it's really quick. And it's vertically down the screen. I kind of assumed that it was the backlight turning on but I'm pretty certain that happens on the sides right?
Right now it's 10:00 and this issue happens right where the "1" is on the clock at the top of the screen. So starting from that 1 all the way to the bottom.
Again it's REALLY fast - but it's noticeable, I'd have no problem showing it to someone in front of me. It just looks like a single line about the same width as the "1" as well. It almost seems like the one tiny line is showing before the rest of the screen, like if the screen were a "loading process" that line would be the first thing to appear before the rest gets backlit.
Not sure if it matters but it's the model I9100M from Virgin, just incase they are made differently somehow.
This phone has no backlight. The LED's are all individually lit.

Hmm, not the same problem as me - certainly nothing to do with the time here - it was in the afternoon when it happened with me, and my lockscreen clock's in 12 hour format. Clock's also at the bottom of my screen.
Been trying to reproduce it, and can't.

No no, I wasn't saying that the clock had anything to do with it, I was just trying to describe where the line appears on screen. I was also talking about the clock that appears at the very top, not the one on the lock screen. If I just continually tap the power button on and off I can see the "line" appear every time exactly in that spot.
It's pretty noticeable, unless you have the phone away from you - so if you don't see it then it probably isn't happening.
Does anyone think I should return this and get another? I don't really want to run into issues later and have to send to manufacturer. Is this problem big enough that I could get it replaced without issue?
Thank's for the replies!
Sorry, misunderstood. Definitely not my problem, I have no clock in the status bar.
If it happens every time, I'd probably return it if I was you - could be the precursor of something more serious.
Hi again, Thanks for the replies. I realized today that the issue is really only noticeable if you're in a dark room. Even in a semi-lit room it's almost unnoticeable which is probably why I hadnt seen it thus far.
If anyone wouldn't mind flicking the lights off and taking a look I'd appreciate it. If not I'll just return it.
thanks again forum!
I experience it too (at least I think we are talking about the same thing)..it's like it's stuttering and lagging after being in standby. So the first time it renders the lockscreen, the first few frames seem to be rendered at a different pace. If you turn the screen on after a good break, it'll likely do it, but after a few times in a row it instantly shows the screen.
Perhaps it relates to how big the wallpaper for the lockscreen is. I'm not sure, but I've had some huge 2mb pictures set as wallpapers for the lockscreen, and afterwards I think I decided to select a smaller image. I don't know if it was just a placebo effect, but anyways..it still does it with my current picture. I don't really care. You could try a different lockscreen from android market and see if it helps, but I think every SII suffers from this.
I have this exact issue too and it really annoys me! I also bought the phone from Virgin if that is relevant. It's a white streak on the left of the screen for me and only happens every so often. So what's the prognosis? A software fault? Hopefully fixed in a subsequent firmware update? Or a hardware fault worth repairing?
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.
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.

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.
