Hi all, previous LG E900 owner and current Omnia W owner.
Since there is no dedicated thread for this phone (why?!) I think this is the appropriate thread to post this.
As the title suggests, my phone has blurry lines on screen. Like a burn in or something. Imagine you have a dirty window after a rain but with vertical grainy lines. I cant actually express it better and I do not have a good camera to take a photo of this.
The lines do not move as the images and colors move. They are static. The problem is heavily apparent on gray background. Worst exhibits are on the keyboard and on the numeric pad of the phone app, right there where you press numbers to make a call. Also, it is clearly visible on lower brightness, not so much on higher but still there. It is also visible on other colors too, even bright ones like red and lime.
After googling it I found out that many Samsung Galaxy S and S2 users have experienced this problem, even on newly bought phones. Many exchanged them, others learnt to live with it. So as far as I understand its some kind of defect on these screens and it really is a matter of luck what you get.
Any ideas on the matter? Any owner of this phone that experiences the same problem?
Let me state that I dont have a screen protector on the screen, yes I have cleaned it like a hundred times in the two days that I have it in my hands.
Please, try to avoid answers like its banding of colors or dust under screen and such. I have used LCD and AMOLED screens alot these past 2 years and this is the first time I see this.

I have this problem too. It's a pain in the ass, I don't know why and how to fix it. My phone is a Samsung Galaxy S Advance, I've decided to open a thread today, like you, because no one reported the same problem. It's like a minor issue for anyone but it's clear that something is wrong with these Super Amoled screens, for me it's a real problem because it takes value from the phone and of course I think it's a piece of junk. I wouldn't be able to sell it on the price that I want it, imagine the deal...
Ok, if anyone knows what a heck is going on I'm gonna be more than thankful.
I have posted this in SGS4 Q&A, Help & Troubleshooting but it's getting no responses there.
Most threads seem to be by potential buyers asking questions about the phone, while issues have topics here.
If this is not the right place, or the other topic is misplaced, please delete/merge either.
So, several people have reported this issue.
While booting, the black is actual BLACK. While charging, the black [not the green/grey battery] is actually BLACK.
When you reach the Samsung animation in the booting process, the areas of the screen previously black get a reddish tint.
On closer inspection, all red subpixels are on, at low intensity. As far as I can see brightness setting does not affect this phenomenon, nor does Display Mode.
i9505 On XXUAMDF:
Comparison, white image, lowest brightness:
Can people report their firmware and model and whether they have this issue? It's mostly visible in pitch black rooms, but you can tell the blackness isn't OLED-black in normal situations. It's obviously a big issue as it will also drain additional power compared to pixels that are off.
I have exactly the same issue, MDF firmware
You can send back to Samsung to get another one, it's faulty
Samsung chat (NL) tells me I should return to the reseller. I'm sure they want to send it back for repairs instead of a swap
Mine too

I would have thought it's a software problem. I have noticed this too and now it bugs me. You're right, the first startup screen, it IS pure black, but going to the next animation, you can clearly see the red pixels come on when it's supposed to be black. But because it CAN do the black on the first screen, doesn't that mean it's something else?
Please let me know if you are able to get a replacement phone that resolves this issue. I think I have a few days to return mine, but you'd actually never notice it in most times of the day. You have to be watching the phone in pitch black to see it, and probably looking at a mostly black screen. But it seems like more that you're not getting the benefit of energy savings of "off" pixels.
There is a totally noticeable red tint to the black.
Rgds
It could still be a software problem, but then a lot of other people would suffer from it as well. I guess its just too unnoticeable. You really have to be in pitch dark, but once you know, it keeps bothering you I'm not sure of what to do. If the store says it will do a swap, I'll swap it. If they want to bring it in for repair, i guess I'll wait a bit for an update (another user reported that it fixed his problem).
Still, if its just a few reports, shouldn't it be some kind of defect, right?
I would really appreciate if other readers in this thread could check their phone for redness, regardless the outcome, please post your result and firmware version. Thanks
BTW, you can get an entirely black screen by
Dialer -> type *#0*# -> Vibration
Ignore the vibration and wait for your eyes to adjust from the bright white screen. Its hard to miss.
Have you seen this post?
Somebody in this thread mentioned black being a bit reddish (not turned off) and no smudge issue. After flashing another firmware the reddish was gone (pixel turned off) but now he got smudge instead !
So yes - I think it could be something do with delay turning pixel on/off

Yeah, saw that too. Still weird Samsung tells me to go to the reseller if it is fixable with firmware. Having said that, shouldn't a lot more people be affected when it's a software issue? Good thing is, first boot screen is all black, so it's not the screen imho
Apparently the Note 2 also suffers from this:

Nb
It is hard to notice in a bright environment but once you know it's there you'll always see it.
Power savings, extra wear for the red subpixels, and non-black blacks = lower contrast. This needs to be fixed.
can people having red pixels issue check for screen smearing ? if im right then people with this red pixel issue wont notice screen smearing effect
Someone with the red subpixel problem should test for smearing.
If it doesn't smear, try flashing the same firmware as someone that has the smearing problem and see if it fixes the red subpixel problem.
This will confirm if both problems are hardware or software related.
Just got off the phone with my retailer. They are going to investigate the matter with Samsung (emailed them a picture) If it's faulty, it will get swapped. I will keep you updated.
Recieved a call from Samsung; they are not aware of this issue, but they are going to investigate the matter. In the mean while, i can exchange my phone, as they will consider it a DOA.

This is a pretty big deal if Sammy says your phone is detective and needs to be replaced.
I'm afraid under this situation, there are quite a few S4's that need to be swapped out.
Good luck with the new one! Let us know how it is.
Allright, redness is gone, but now i have the screen smearing mentioned in http://forum.xda-developers.com/showthread.php?t=2252445. I am appaled :/
Same firmware versions, everything the same. Samsung has serious screen issues.

i told you just few posts back as of now it looks like either red sub pixels or smearing issue. its upto the people to choose. lets hope this is due to software.

Im having the reddish tint too.. makes no sense if its not a software problem.
Sent from my GT-I9505 using xda app-developers app
I used my Galaxy note 2 for 1 year and just these days when the screen is turned on, I can see stripes on the screen.
It's obviously and ugly. I've had it! I didn't take pictures but i searched the similar pic attached, it's vertical lines on the screen.
I bought it to repair shop and they said that i need to replace my LCD screen and digitizer assembly. It will cost me $250, if i agree.
So, What's the problem of my phone? anyone knows? Or Is it possible to repair it by myself? I don't want to pay so much money .
Any advice would be appreciated
Hi
Thanks for writing to us at XDA Assist. Unfortunately you don't have many options, you're dealing with a hardware failure.
Option 1:
Pay for the repair to be done.
Option 2:
Do some research and undertake the repair yourself (consider this very carefully, quite often when an unexperienced person attempts something like this they do more damage than good).
Option 3:
Put up with it.
Thread closed.
Dear XDA community...
I've been a passive participant in many of your threads and most of the time I have managed to solve my issues thanks to your replies. Finally i have decided to join you and hopefully also help in some of the cases.
My current issue is a Samsung Galaxy Trend which display and digitizer have been broken. I have easily managed to replace those, both of which were working fine on the first boot. The display once got frozen tho and since that time the only thing i can see is a white snowy (no-signal tv alike) screen with some colorful dots here and there. Replacing the Lcd once again brought no change, so i guess it may be either pcb/ic issue or a software bug. I will try uploading a pic of the display as soon as possible.
I hope someone might have encountered this kind of defect and could help me solve it.
Best regards,
Damian aka Infernaesty.
Hi,
Thanks for using XDA Assist the snowy thing is because either the way you have fixed is not right and there is some connection issue to board and display or you may accidentaly damaged glue of Display and board fix which some devices have best thing is to get it repaired by Samsung Official Outlet or in other Mobile Repair Shop has further anything may damage other parts of device
Good Luck !

Hello & welcome to xda-assist,
to my point of view you already answered the question yourself, if there's any doubt you did that replacement right and it isn't working like it should you likely made a mistake, only recommendation is to triple check the procedure you did by comparison to a replacement /tear down video and find the error, also check if you really bought the right hardware...
Following link shows some tutorials & stuff, time to solve some riddle, I'd guess..

Nothing till now
Dear friend, thank you for your fast response,
i contact them and i sent them a video and they answered this:
Thank you very much for ordering our product and for kindly bringing the issue to our attention.
For this problem we have confirmed with product department,the screen is not welded and needs to be reworked.
So what i have to do? i told them that i re-asseble the phone many times.. what means that the screen is not welded??
Thank you one more time my friend!!
