Stuck pixel!

I just got a stuck pixel on my phone in the bottom of the screen, i picked it up today from the local T-Mobile store, anyway to pix it or am i gonna have to return it?

best thing to do is to return it for another one
it's very rare to see a stuck LED on the SAMOLED+ screens
it stays even after a reboot?

yea i rebooted it 3 times and i also ran those youtube stuck pixel fixers that flash billion colors on the screen really fast...it didnt work its still there

Stuck Red Pixel
Anyone else have one?
It's really not a big deal, except that I've only had the phone for two days. They usually go away on their own after time but I have to admit it's annoying.. because I purposely look to see if it's their when I'm in the web browser, which is really the only time I see it (only really visible on white background)

take it back and change it ASAP

Dead Black Pixels? Picture not rectangle?
Okay so I was about to go to bed when I realized that the phone died...so I plug it in and I was like wooooahhhh wtfff...
I see all these weird dead black pixels and on top of that the battery isn't perfectly rectangle...the back part is zigzaggy...I tried to take a picture but it doesn't come out..
Try it. Go into a really dark room and turn phone completely off. Plug it in and wait for the battery picture to come on...any of you see the multiple dead black pixels and non rectangular battery? ?
An alternative way that I also tried was a black background on the lock screen...I saw only a few dead black pixels...not as much as plugging it in...dam I thought my batch was perfect...

You can take a screenshot by holding the home key and pressing the lock button.

That wouldn't help because its a hardware problem. I'm going to return it and wait 2 months and get it at a cheaper price....

are you sure those are dead LED?
there's no pixel in SAMOLED displays, each "pixel" is actually a LED
so are you absolutely sure those LED at dead?
if you put a HD picture on screen of a uniform colour, does it leave any black spots?

That's what I meant, thank you for clarifying....I see splotches on dark shades of black...its like the screen is dirty, but isn't.

I actually have a spot I didn't notice until last night, its a red spot that's stuck at the bottom. So that's a dead led?

Samsung Galaxy S III screen problem with black color in the dark

Last night I was laying on my bed watching a movie on my phone. I notice somthing is wrong with my screen, when there's no light in the room and my phone is on a black screen. I have something wrong with my black color on the bottom of the screen, its really hard to describe but if you look at it, it looks not normal. But when im not on a black screen the screen looks 100% normal you cant even tell there is an issue with my screen. I was wondering if other people are getting this issue. Just go to a room that's really dark, put your phone with a black wallpaper and look at the screen you might have to turn up brightness to see it.

OOOOOOO wow... thats lame but I feel alot better that you said that. thanks for letting me know.

mine has it too its normal

In very dark conditions, all these screens seems to have a noticeable glow on black, and lines, dots, and/or spots that are darker (like ink marks). I got mine replaced twice and settled on the third with only a single small spot on the right middle of the screen.

Yea, i have it too. never really thought anything of it... kinda figured it probably was just something to do with amoled screens. Not like i'm frequently looking at a black screen anyway... and it's only really noticable in the dark.

they look like black blotches of paint or something right?
My Infuse and SGS2 both have them is thats what you are referring too. if you load a brown image like XDA brown far more noticeable.
that is how i noticed them on other two devices.

Maybe I'm just lucky. But I don't have those blotches on my s3. Did have them on my atrix 4G though. And this sgs2 I was borrowing from a friend. Only had my gs3 since yesterday though. Maybe age matters?

Yea I've just got a small black blotch at the bottem left of my screen. Only noticeable when its pitch black
Sent from my SAMSUNG-SGH-I747 using xda premium

What's funny is. On my Atrix they were visible even with "color" showing. Faint. But visible. Very noticeable on black screens though. Gs2 wasn't too bad. But this gs3 shows none whatsoever.

[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 just checked my over 2 year old SGSIs screen and do not see any blotches. You are also the first person that i have read about that has any problems. That does not mean youeare alone however. I have heard many running 4.2 complaining about black artifacts being seen on the screen.

Some people here are having the same problem while others are not... luck of the draw I suppose... doesn't really bother me but if it bothers you try and see if you could get another in its place

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.

Burn In

Hi everyone
I recently noticed this black burn in on grey backgrounds. The screen works ok normally but is anything grey is displayed then a black area is noticed.
I tried several ways to fix it but with no luck.
Any suggestions?
I'll include a picture of the screen when I get home.

I noticed that too on top right side of the screen. Meh, luckily, I almost never have grey color on my screen

There have been a lot of people complaining about this issue. Nothing you can do about it. It's just a disadvantage of Amoled screens, for now you have to live with it or try to get a replacement.
Sent from my GT-N7100 using xda app-developers app

I guess I will have to live with it.
I too almost never have grey screens except sometimes when I start some apps. Anyway I just wanted to clarify my issue and understand it better.
Thank you.

Burn in happens quicker on amoled than on lcd displays. Been widely publicised since the S2, but it's a hardware problem so you'll have to get the display replaced if you want to correct it. Most likely occurs if you have the same colour exposed for a long time. Blue makes burn ins occur quickly too, but anything light in general quickens burn ins.
Best bet is to use dark themes and avoid keeping your screen displaying the same thing for a long time

White screens look with a subtle pink tone towards one side... Anyone?

After a few days of use I'm realizing that, for example, in mostly white screens, it looks a little pink towards the right side (landscape), this is EXTREMELY subtle but I can really notice it in a full white screen, it's still white but with a very, VERY subtle pink tone to it, I wonder if it's a common thing....
I'm very picky, don't know if normal people would realize that (in case they have the same issue...)
It's almost half screen.... Anyone?

I'm not seeing this on my screen, but maybe my eyesight wasn't what it used to be. Try taking a screen shot and transferring it to your computer and check if the pink tone is visible from there. If not then it's probably faulty hardware.

It looks fine to me.

Since I bought it at Best Buy I returned it and got a new one, the girl gave me a little bit of a hard time because she couldn't see anything wrong with the screen... I told her it took me 2-3 days to realize there was this light pink tone towards one side and it was only visible with white backgrounds.... So at the end I was able to return it, I'm glad I did because I was getting very uncomfortable with this.... Btw, there's a very good app to test the colors on the screen, it's called Display Tester (by gombosdev).. Really nice.

I don't remember were I read that if you turn on "reading mode" will give a pink tinge to screen. I think is mentioned on the manual but not sure.

Reading mode gives a nice creamy/yellow tone throughout the whole screen (obviously) only on user selected apps.
