This is a hardware issue that has been reported by several others too. You should have no trouble getting it repaired free of charge.

I have those too and the display have yellow stains all over too.
I kinda recognized them since the last Friday...either I did not realized it before (I need to check up my eyes..I guess) or they were not there before.
It is being sent back to Sony at this very moment.

Wow, this is just unbelievable. Screen issues, 3G/Wi-Fi issues, GPS issues.....the list just goes on and on. And yet Samsung is already working on Galaxy 3. Maybe they should have worked on this one a bit longer before releasing this problem ridden thing. Last time I ever buy a Samsung phone.

you hear more about the bad problems, because nobody makes a thread on this forum just to tell, that theit phone is working
i have none of those "problems" you listed above. every phone has such problems. no phone is perfect.
there is no need to tell, that you'll never buy a samsung device again(you probably will), just because you read on the forums, that some people(not that many) have problems with their phone.
OMG! Today, my Samsung Galaxy S2 whole screen turn yellowish. Extremely yellowish. After restart the phone, it back to normal again. Firmware or Hardware problem?

Fast vertical lines on screen wake up

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?
Using Lightning ROM 1.5
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
Sent from my GT-I9100 using xda premium
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.

Strange white dots on the screen, dead pixles?

Hello
Yesterday at night when I was playing "another world" I noticed 2 unusal dots. The first one just above the search button does indeed move everytime I rotate the phone. Everytime I rotate the phone to left the dot appears but when I rotate it to the right, it comes back again, WTF? Anyone have this kind of issue? I have attached the pictures. Anyway to fix it?
EDIT: It doesn't seem to be dead pixles, it something else but I dont know what it is...it's moving when I rotate the phone and AFAIK dead pixles does not move.
Something else strange I have noticed is that everytime I close an app by clicking the "home button" for example Angry birds, the sound is still there. I need to close via the task manager in order to make the sound disappear. Not the sound of the game but a strange sound is still left
EDIT2: Is it possible that is water? Because I installed invisible shield some day ago...maybe little water got under the screen and is "floating"?
It won't be "water" cause water under/on the screen would never "rotate" with screen, I guess it's some "background" process that to monitor some action, and a minimum GUI was "1 pixel". So it a white dot

Ah oke I was scared it was water. So there is no way to get rid of it? Its normal?
Did these dot only appear while you play this game or always on your display? Try to make a pure black(#000000) picture and view it as Full Screen mode, if it always appear, then it maybe some social apps or monitor like face recognition or gesture recognition services. If it only appear in these game, it maybe some social tools integrated in your games or cheating tools.
I guess it's posterior one, so just leave it.
If it's always exist, and you ARE a GEEK, then check every PROGRAMES on your Razr and figure out which/what perform this
If you're not a geek and it always exist, try to backup your system and data, then do a Factory Reset. Everythings goes well means it was some issues within some Apps you installed, If it still there, then it must been some issues in your integrated apps or some ROM issue
you can use es task manager's screen checker to check for dead pixels, it can also kill task, and manage startup tasks. I find it faster than razr's built in task manager.
I have no idea what that little white dot is, I also noticed it when I got my Razr back in November. On the bright side I can tell you that out of 4 Razrs I've had and my girlfriends 2 all 6 of them have had the white dot in that same spot. I don't think it's anything to be worried about. Also, neither me or my girlfriend use a screen protector that requires a solution to adhere so you can rule that out as well.

I just tried a pure black picture from the app "Dead pixel Detect and fix" and the white dote was still there. It is not just in games it's always there but most visible when there is a black background. I reall have no clue what program I should check, I thought it was watchdog tasker but I unistalled it and it's still there. I am using stock Rom 2.3.6 651.167.21.NonEFIGSretail.en.EU
Is there a way I can take backup when I am not rooted? I have not rooted the phone yet.

I just installed ES task manager and used screen checker, the dot is only visibile when there is black background sometimes blue background to. Is it OK to kill all the apps to see if the white dot disappear?

Ah alright maybe it's suppose to be like that then...I have no clue
Edit: I am performing a factory reset, I will come back with the results.
Edit2: It looks like its still there after factory reset.
I'm beginning to think it's just an optical illusion brought on by glare and the capacitive buttons but who knows. It doesn't really bother me at all to be honest I just found it to be weird.

That means you have dead pixels. The other one at the corner of the screen is the shiny reflection from the phone design.
Bring it to a service center for an exchange, it looks like a big chunk of dead pixels at one spot.

Why not google and find out?
I don't have any and can assure you if I did I would return the phone and get it changed.

Dont know if its worth exchange it and possible get one even worse..
I have emailed the store I bought it from, I think I now have had the phone in exactly 2 weeks. If its going in to repairs imo its not worth sending it. But if they exchange it then its ok. But the problem is I installed a Zagg shield on it...can I remove it and apply it on the new phone?

I don't know if you can take the screen protector off and swap it. I don't use one don't like them. Especially the wet install ones. Water and electric do not mix. Ever. Even in tiny amounts.
If it doesn't bother you just leave it. I'm just saying I wouldn't accept it. These devices are way too expensive to have any kind of defect however small.

I agree. I will definitely push the store to let them exchange it for me, even if it's one pixle a phone for 600$ should not have any damaged. About the screen protector **** it, if they exchange the phone for me I wont use one anymore.

[Q] Samsung Galaxy s3 Display/Screen issue

Hey everyone!
Few months ago I bought a Samsung Galaxy S3 (international, GT-i9300) and I noticed a small issue with the display/screen.
A row of semi-transparent icons appear on the screen for as long as it's ON. I don't know if anyone else experienced this issue, to help me out, but it is annoying, wherever I go, whatever I do, those icons remain on the screen, semi-transparent.
Whenever I take a screenshot and send it to my PC, the icons do not appear on the screenshot. I would love to know what this issue is and if there is a possible way to fix it.
I would upload an example how it looks but due to my low post count I am unable to add external picture links.
Use the search facility, this has been asked before.
It's the OLED showing screen burn, like tube TV's used to. There is no cure.

Mine has started with screen burn. In theory its only 12 ish months of every day use. I hope the screens are better on the newer sammys for when my contract ends in december.

But thats not a fix. Oled saver app fixed it for me, but I wonder if anyone else is having this issue, and if do, if they've had any luck fixing the problem?
