Hello all.
I have rather a weird situation. I have a Lite'ning rom, and it comes default with the CRT animation. However, sometimes the closing animation will put a 'defect' on the screen just before turning the screen off.
It looks like the screen is broken and the white lines stay there. Now, this happens after some time the phone is on. Once restarted, the phone will go back to the normal state.
I have to repeat this: This defect is present for only a few millisecond, during the CRT closing animation. The screen has no defects or any yellow lines.
Does this sound like a software fault or a hardware fault? Also, since I am the first one who is reporting this, is it ok to assume that I am the only one with this 'fault'?
Thank you,
Mo.
55 views and NO answer.. I mean, people can't even say whether they ACTUALLY experienced this or not?!!?!
yes i get it too. it must be the crt animation thats.. not optimized for sgsii
I am guessing what you see is identical to the 'no-clipping' effect seen when you go through a wall in a really old game like doom using the no-clip cheat.

people, has anyone of you noticed white vertical lines that appear for a fraction of a second when you power on the device? it happens right before lock screen appears... best could be seen in a dark... seems like there is a problem with screen initialization on a driver level...
Could someone check this issue?

Sounds like your phone is defective.

i prefer to be more optimistic due to the fact that many others reported the same problem on different forum... xda is more reliable, so I'm trying to collect the opinions here as well
Mine has this, noticed it for the first time yesterday (hadn't seen any reports of this at that time).

don't worry, I think this effect is present on every piece of 9100. more or less obvious for users... it might be not vertical lines that people see but the quick white flash

What effect does this have on any other aspect of the phone, or is it literally only that fraction of a second that there is any apparent effect?

if it is really a problem of display controller low-level driver - it might cause some serious problems as time passes... total screen failure, for instance... as i remember from past cell phones - it was the first sign of upcoming screen death...
but i think that in our case - this is just a minor driver issue in screen initialization process... at least i believe so
I have this problem with the screen as well! and it's annoying to see those vertical lines whenever I wake up the screen.
sometime i can see the lines with "CRT Screen Off" mod, but without they dont appear
Try to do a backup in CW recovery and flash a stock rom.
It can be the CRT effect or any other custom rom issue.
It would be great to know if the problem is due to your custom rom or not.
Hey, sorry to bring this up again, but I'm having the same problem, and it's really bothering me. If there's any way of fixing it, please let me know, I just uploaded the stock ICS 4.0.3 for my device, and it started to show.
mine too has this
Mine also has this issue. only visible in the dark
yeah, same here. I thought i was the only one having this

Noticed this straight away when I got my new phone and it was there before I flashed a custom anything
***Bezeke HOLO LPQ base running bits stuff from everywhere ***
I also have this issue
One large, white vertical line. Clearly visible in all lighting conditions
However sometimes (rarely) it doesn't do it.
I have compared this to a black galaxy s2 (mines white) which doesn't suffer from this issue. It actually seems to delay the screen on / unlock time
The black loads the lockscreen at almost the exact same time as the white displays the lines.
I've been putting off returning it under warranty as I can't do without it..
Its like a jolt of power that hits the screen
***Bezeke HOLO LPQ base running bits stuff from everywhere ***
yeah, i recently got a phone off someone, and it's been bothering me since, there's no way of fixing it? i hope it hasn't caused anyone trouble, i recently switched to iPhone to this phone and i'm absolutely loving it besides the white flash

If you mean the minute, almost "patterned" grey lines then yes. Every Galaxy S2 has theses.
But bright white, clearly visible line/s which delay the screen-on process.. No, not every Galaxy S2 has it.
Especially if they don't always appear
i don't think its an issue with the phone i had it running an old version of omega rom the latest 5.1 does'nt have that problem.
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?
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
I have been having an issue when I close the camera on my DNA. When I close the camera the video sometimes flakes out like there is a problem with the screen. I always keep auto brightness off and I leave the brightness the whole way down. It only seems to do this when the brightness is the entire way down. When opening the camera the screen gets very bright and the problem seems to happen when the screen is rapidly getting darker when the camera closes. Like I said, I can only produce the problem when the brightness is the whole way down. Once I lock the screen and unlock it, the phone goes back to normal. I have taken multiple screenshots when the problem happens too, and they always turn out normal almost making me think its a problem with the screen.
I am rooted and running the stock deodexed ROM and I have been able to produce the same problem on UKB ROM and also Genome, however I cant seem to reproduce it on the stock odexed rom. So because of this I'm wondering if anyone else has seen the same problem? I can't really get the phone replaced when I can't produce the problem on the stock ROM.
Here is a youtube video I uploaded of the issue to show exactly what's goin on.

same issue, different way of getting it (or same actually, i always got it going into the gallery)
whats your screen animation set to under dev options? whenever i was set to 0.5x, this would ALWAYS happen. 1.0 and above, NEVEr. now i have animations OFF, and it has never happened since.
moral of the story: don't use window transition animation at 0.5x or else this glitch occurs. it was the first thing i reported to HTC in my thread but yeah, no animations and i'm fine...and 1x animations and it's fine too
btw, my brightness was at 40% when it happened. doesn't matter what % it was for m.e
Yeah my transition animations are also set to .5 so I'll have to try it turned off. Is your phone rooted or is it running stock ROM? One of my friends has a rooted DNA and he can't produce the problem with his phone so I thought it was only mine. You are the first person I've seen have the same issue but I was hoping it was a more widespread bug and not just my phone.

stock No root. I guarantee its the transition animations at less than 1. have him set it to that and do what I did in the video... that's how I was able to quickly reproduce it.

OK well my wife's DNA is stock unrooted and i set her transition animations to .5 and brightness all the way down and I cannot get her phone to do it in portrait or landscape. Mine has the problem constantly. I just wonder if the problem only happens on certain phones.

turn her brightness up. do it at 50% or so. that's when mine did it.
DUDE way to jinx me! wtf. hahaha i turned animations on to 1.0x for the first time in like 3 weeks, and after taking a pic, my screen faded out again!
ugh. anyway, it's back to off, so lets see if it does it..

Haha sorry man!
BTW, I have tried everything with my wifes phone and I cannot get hers to do it. I do know one thing with mine was I use nova launcher and I had the slide transition enabled. I turned it to stock JB animations and haven't been able to get mine to do it since then. Even on .5 transition speed and brightness the whole way down. I'm just happy I don't have faulty hardware.
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.
