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?

I see the samething when doing the Screen brightening glitch in a dark room.

When I turn off my phone and connect to the charger in the dark, it show the battery charging and surrounding it are black dots and lines. is this even normal? does everyone got that or its my defective device?

Black dots on the screen?

Hi. I bought a galaxy nexus today.
When i have the phone on and the screen is black then i can see some black parts(the screen is black, but there's some parts that are extra black). Is this normal? Or is the screen broken? Going to post a picture soon.
Btw my dad dropped the phone today. Maybe it's because of that?
Thanks in advance

This happens on my screen too. It is only really visible in a dark room when the screen is black like when FaceBook is loading a picture. I also get the black dots and a black line horizontally across the whole screen. I never really thought much of it because those pixels seem to work fine under normal conditions.

Normal.

Ive noticed it on mine too. Hasn't really bothered me since its hardly noticeable. I think it is worth mentioning that my dots aren't like single pixels. It is more like a blotch or a cluster.

I have a Galaxy SII (TMO) and sounds like this is similar to the issue we are all suffering from. Here's a link discussing it - http://forum.xda-developers.com/showthread.php?t=1300133

Okay thanks

Transformer Prime has tons of black dots.. i'm guessing it is the touch sensing stuff on the glass/under the glass

i tried to contact samsung care here but they said its normal no need for other phone & if u want leave ur phone for 10 days to see if its need to replace or not
but here in egypt we have a bad service they dont know anything & say its normal
its show in notifications bar & anything have a black color
it shows in just in dark with low brightness
is this spots & lines r normal?is it going to be big in future?

What I know they don't grow or get worse. They are static.
I have some on my device too but as I said, only see them in unnatural circumstances. Just try not to focus on them.

[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.

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
