[Q] Is this a screen defect, check this please

With the screen off, in the upper half of the screen I notice some horizontal lines like a shadow from a circuit board behind the screen. Can someone please check this? You have to view it at the correct angle and lots of light like from a flashlight or sunlight to see it, it is hard to see. Is this normal or a defect? It doesn't effect the screen at all when it's on and you can't see it when it's on.

Can someone please check this so I know if I should return and exchange.

I see nothing on my screen. I look everywhere on the screen, even with the light shining right at it, no sight of the curcuit board on back.

You need to be in direct bright sunlight or a flashlight pointed inches from the screen and angle the screen a little forward to see it, it almost looks like RF shielding or the outline of something behind the screen. I just wanted to know if anyone else has this before I return it. Thanks for your help.

I've noticed that in mine

I've attached a picture I drew of the pattern I see (in gray) when I view the screen OFF in direct light/sunlight. Is this the pattern you are seeing or something similar? Someone please confirm, I would appreciate that very much.

That's the one

Thank you rdwing for your reply. Is it safe to assume this is normal and not a defect?

I think it has to do with the digitizer, most likely normal. Don't worry about it.

I don't have it and don't want it, wouldn't trust it at all! You got a really nice phone , why risk it, I'd have a new one by now, don't wait on returning it!

It is very hard to see unless in very direct light. It needs to be direct light or you will not see it. Try it. It almost looks like the outline of this circuit of the epic touch that I attached (ignore the circled chip).

I need one more verification before I decide it's defective and exchange, anyone else has some input or can verify this for me please?

I'm leaving work soon and need to know if anyone else has this so I can exchange? Take a flashlight or go in the sun and see if you can see the line with the screen off. Anyone...please?

Thanks viper786, I guess I need to get it exchanged, hopefully the exchange unit is not defective too...

So I exchanged my phone and this screen was even worse! Not only that, in a bright room or in the sun I could not turn on the screen with the power button, it would flicker on and turn off right away. I brought it inside the sprint store and the screen worked fine again. It turned out the replacement was defective too, screen only turned on when conditions were not bright. (I think the Sprint people thought I was going nuts so I showed them and they were surprised). So I exchanged again and hopefully am good now.

This pattern makes sense, and according to ifixit the glass and panel are glued together so maybe same came out better than others. See here http://guide-images.ifixit.net/igi/eGp3Nsu4paJjUhcW.medium

Ok...
So I'm reading this thread, and I'm curious about the "line thing", and I'm looking for it possibly being on my phone, but I don't see it, so I re-read the OP agai.....
Wait.
This whole conversation is about something that might possibly be seen, but only when someone's screen is "off" ???
Really??
I'll say it: ** Who gives a rat's ass?
I just don't stare at my screen while it's off, with a flashlight pointed at it. (Call me crazy.)
Maybe that's why I've never noticed such an "inexcusable error" in build quality.

I think mine does.....
I think I should return it.

what are your settings? it would be easier for us to try and replicate what you are seeing on our phones if you would tell us what exactly you are doing on your phone to see these lines. what brightness, what wallpaper, what app, etc..,?

so does anyone know what Im talking about with the letters of the keyboard being burned into the screen?

I looked at the test and what they are showing I don't have that problem on mine however.

Most likely you will not have these issues with our phone. If u are having white lines or burned in images on your screen.I suggest going to the sprint store .

I have horizontal lines going up and down my screen. it only happens at around 80% and 20% battery with the brightness below half. it is best seen on a white backround. I looked into it and I have come to the conclusion its these screens.

It's a bad display, regardless of what they tell you. I had the same exact problem on the first S2 epic touch I got. There are lots of them out there with that same problem, not sure if it's a manufacturer defect or what, but definitely not supposed to look like that. I took mine in after 3 days of use , I was NOT gonna ride with a display like that, (for me it was even worse in a dark room with low brightness, really obvious then...also had a pink tint when scrolling on the white background xda app), got a replacement and it is perfect. No dark/light lines, etc.. Everything looks great no matter what I do.
Sorry to hear cause it sucks, considering how high end this phone is..

[Q] Display Imperfections/Black Splotches

So I understand this is a recurring issue with some AMOLED displays, but is anyone else noticing black splotches on your screen if you put a fully black image on the screen, turn the brightness all the way down, and look at your phone in a very dark room? I'm curious how common it is before I complain. I'll post a picture tomorrow if I can capture it. It looks kind of like an ink trail near the middle of my screen. Thanks!

I have them on mine; there are two splotches about 3/4" long roughly in the middle, just left of center. Doesn't bother me though, since I can't see them during normal use.

Had the issue on mu-tiple Samsung skyrockets...the original note and on the s3.
I have seen them on some note 2 but mine I have not found one yet.
Sent from my SPH-L900 using xda app-developers app

I have a small one at the top left of the screen. My first one was right down the middle. My OCD took hold and I swapped it out. It's the same thing on my new one.
Sure, I wish it wasn't there but you really have to have perfect conditions to actually see it.
It actually has something to do with inconsistent electrical charge or something. There's actually a team for this but I can't remember it.
LCDs have dead pixels and amoleds have these splotches.
The DROID Razor is really bad as is the PS Vita. It's just that tech.

Be aware of screen defect!

So I got gs3 a week ago and loving it so far. But I started noticing the screen has some issues.
Everytime I am on blank screen with just the back light on, I notice multiple dark circles thru back light. They are about the size of peas and you can only see them in darker room. I am trying to take a picture but still not successful.. again you can not see them in normal light or when you are looking bright images. .you can only see them on blank screen with back light on. (Examples: when you start the phone and only Samsung logo during boot. Or when you go to seetings and choose lock screen, the blank area with back light on shows the defects. )
I hope you guys don't have that issue, because it does bother me when I am using phone at night..
I called tmo to replace it and hopefully new one doesn't have same problem.
Cheers,

You may want a different phone if it bugs you. Purchase a phone with a different style of screen or read the forums before you make a purchase.

Common on amoled screens.
Sent from my Galaxy S3 using neighbors wifi

A simple Google search would of net you the answer. Those are dead pixels almost all amoled screen have does, but if they are really really big you can definitely try to get a warranty. Only thing is your next phone will probably have it too either for better or worse. If it's not too bad I would stay with the phone, technically if you don't think about it you get past it not many times you would notice it anyway.

I have these too. Like you, only time I see them is a completely black screen in the dark. In other words, where's the problem?

Screen Burning or Dead Pixels?
I think what you are referring to is screen burning. This case is very common among OLED displays, kind of how plasma TV's have burns on the screen. It's there but its not that bad since this type of technology gets it (for now....the tech is still way too new). However, it helps to not keep the same picture or whatever showing for long periods of time, as this can cause a burning outline of the picture. In this I mean, something that is displayed that doesn't change. Remember some screen may get more burned then others but it will still be there. For the reason of this burning, I'll let you search it up. If that doesn't answer your problem then let me know, but if it is dead pixels (which I dont think it is) then you might want to change it. However, your problem sounds like the common problem called burning.

This is very common in all amoled screens. Same was the case with my vibrant. Since these are only visible in a dark room with a black screen, its not that big of a problem, I imagine. It's not so much a defect as it is an aspect of the screen type. Think of it like this... if you purchase a Mac over a Windows computer, it will have aspects that you dislike that the other likely won't have have. But the same is true of the Windows device (although not likely ha)...if it is a deal breaker, avoid amoled in the future.

Have this also, even on Note 2. Especially, while watching Netflix or screen is dark

Seriously there was a long thread about this when the phone first released. Could we not resurrect this?

You might want to exchange that. The definately isn't burning that I am talking about. So yes, go ahead and change that out. I don't have that on my phone so it looks like a defect. Those spots almost look like bloches of some sort and looks as if something had burned underneath. That or one guy said, dead pixels (which is a definate yes for exchange).
So go exchange the product and see how it goes for you.

Well we went through thisnwith the sgs2. People found that exchanges just resulted in more phones just like this. Therw was a whole about it there also. It is a defwct in manufacturing in most oled screens for these phones. People have reported it in their note 2s also.

Those Darn Black Specs! Are You Tired Of Them?

So I bought my galaxy s3 outright (meaning full price, I know, some will say it is stupid to do that, but it was Thanksgiving sale and my upgrade wasn't till next year and my phone only had gingerbread.)
After saying that, I bought my galaxy s3 and found out it had a few dead pixels. They were tiny specks that were barely noticeable. After 6 months of use, they increased. Now there are 7x more spots and some are even blotches. Very annoying. That being said, paying 500$ for a device, I wish it didn't have this problem.
How many of you have this problem too?
Note: The specks I am talking about are the black spots on your screen when viewing a black background area (such as loading YouTube video) in a darkroom. They are annoying.

SPRINT GS3 FAQ

I broke my phone a few weeks back and got a replacement from Asurion for $150. I got my original S3 for $360 off contract on eBay and never had any issues with it. Although I saw the black inky spots only when powering off the device when the screen went dark I could see them. Other than that I could not replicate the issue. Anyways, the new/refurbished phone had black inky blots that were visible in low light setting. I immediately called them and they sent a new phone that has no issues.

I was thinking about taking phone into sprint.. decided it wasn't worth it. Maybe the whole screen will just get black specks everywhere so it evens out.
Sent From My Rooted, S-OFF'd Blackberry Curve using the iOS XDA Application for Android.

I had the blotches, so I know just what you're talking about. I could only see them in a very dark room with my brightness all the way down when there was a black background. I took it to sprint within 15 days of getting the phone. They replaced it with a new one but it had the same problem so I returned it again. On my 3rd gs3 now and the screen seems fine.

I work with somebody that switched to an iPhone because his 3 replacement s3s all had this issue. It's annoying but it's not a game breaker. I only notice them on very dark grey screens and 99.9% of the time, it's when I'm booting into recovery or waiting for a video to load. It's not a game breaker because when I'm actually using the phone during the day I never see them. I told him he was over reacting but whatever, I guess some people can't get over their OCD.

As ascertain said above you, they're hard to see and they're best seen when the screen goes black but it still on, like booting into recovery. There could be any number or size of them on your screen, or none. I was able to see them in a very dark room with a my brightness all the way down and a black wallpaper. I also had lux to lower the brightness more.
A lot of people probably have them and don't even know it. My wife's gs3 has the blotches and she didn't know before I told her. A friend with an at&t gs3 has blotches and my first two gs3's had them. Pretty common, I'd say.

I have those black specs and I had them on every Galaxy S phone I've owned. I even had them on my Galaxy Nexus (much worse on the Nexus though). It doesn't bother me too much, screen burn in on the status bar bothers me more. -_-
