Stuck/dead pixel!

My brand new pad has a pixel that won't show green...running one of the apps that says it fixes that... If it doesn't work, i'm going to see if I can get a replacement.
Just a warning to everyone. Be on the lookout.

I've got a dead pixel as well. Near the top left. Doesn't really bother me that much, so I don't really care. Surely one teeny little pixel doesn't warrant you returning it ...?

I used to think that. But if its been like, 3 Weeks and there's already one dead pixel... What does that say for the possibilities?
Just called Asus - he tried to get me to do a wipe.
Are you kidding me? wipe all my data? Asus - get rid of the spiel, its junk. Get ppl who know whats up on the phones ugh

My first pad had a dead pixel. I found it the second day and returned it as soon as I could. It was kind of in the middle of the screen, and I could see it every time I viewed a white web page. Needless to say, it bothered the heck out of me and had to be returned.

i went through 4 tabs until i got one that was fine display wise. first one had a cluster of discolored pixels, like someone pressed their thumb hard on the screen and damaged the area. the other two each had a couple grains of what looked like sand under the glass. All of these were around the same area on the tab, mid-lower left area of the screen.

Mines mid high right...
I'm worried about an attempted unlocking... I tried to unlock my tab before they fixed the c4okt issues, and im wondering if it might've sent them a file about that... Also wondering if unlocking will void it for a screen issue.

Dead and stuck pixels are far from unique to Asus. There is a difference by the way, a stuck pixel is one that is, well stuck displaying one color, these can sometimes be fixed by programs like you are running and/or gently massaging the area with a pencil eraser or something similar, dead pixels don't display any color and are rarely able to be fixed.

My dead pixel I guess just happens to be in a place where I rarely notice it. I tried one of those dead pixel detect and fix apps but it didn't fix anything.

There is one other thing you can try, VERY gently massage the dead pixel with a something like a pencil eraser, that will sometimes get it working.

That's fine and all... but there's a much thicker layer of glass over a capacitive screen than there is over a resistive touch screen... or just a LCD monitor.
Unless I'm missing something here, this advice does not apply anymore.

The screen will still flex. I am not sure whether it would work or not on these devices, I just put that out there hoping it might help.

Don't feel too bad. I just made the mistake of looking at an all black screen on my Acer a510.
NINE stuck pixels!
One little cluster made a shape exactly like the big dipper. Very artistic, with pretty multicolored stuck-pixel stars.
Needless to say I wasn't thrilled. So much for quality control. Sounds like Asus at least isn't this bad.

dark blotch on screen

I just got mine today it is a great phone but then I noticed when I'm on a white screen I see a dark blotch or blur in the center of the screen..i call it a fish eye about the size of a pencil eraser.
Has anyone else seen this ? I'm returning it as soon as my replacement comes hope this isn't a common issue with the nexus and don't want to go through 10 returns before I get a good one.

Don't know if you'll be able to see it from this screen shot.

When you look at it close it looks just like a dimple in the screen behind the glass.

You probably have warped glass from the installation of the panel to the digitizer. One of mine had a bright yellow glue ring about 60-70% down the screen in the middle. Try angling the screen in different lights and see if you notice any wavering... Like a very faint ding on a car. I think whatever machine presses the screens down does it too hard.

White pixel.

I posted last night that there is this really small white dot on my screen. It only visible on light colors like white . But its not visible if the color is really dark. Like on you tube where the search option is it not visible but when i go to Facebook i can see right next to my notification but its small. Anyways is there a way for it to go away? This phone is only like a day old :/ & it was bigger last night but it got smaller because i played a video that repeated blue red and green fast because i heard it make stuck pixel go back to normal.
Also is it a dead pixel or stuck?

Return the phone if you can't live with it.

I'd RMA it, pretty sure they'll replace it free of charge. Although it's just a pixel, stuck and/or dead pixels annoy the crap out of me because once you notice them, you can't stop looking at them every damn time!

Depends on Google/LG's interpretation - Samsung don't except anything under 5 pixels as faulty

I just saw a white pixel on the middle of the screen but I can only appreciate it at dark, when screen is black and brightness set to maximum (which I never have on dark environment). Was that an issue for you? I really have to look for it for a while in any other case. Pixels are sooo small. Don't even bother to rma. No other issue with the phone.
I'm thinking it's just a pixel stuck in a grey colour because it so difficult to see.

[Q] Display brightness issue

I'm currently on my second N3 (the first one had vertical lines in photos) and looks like this one has a bad display. When using Tapatalk with the dark theme, the bottom left corner/edge of the display is brighter than the rest. When testing with Screen Adjuster, the difference is very noticeable. The issue can be seen even with just Thumb Keyboard with WP7 theme.
Has anyone else noticed this kind of problem?

Return it and buy from another store. Seems like these guys are selling you lemons.

The two phones are from different stores, I'm still waiting for a replacement for the first one.

Mine upper side screen seems brighter than below screen.. but this condition only happen when i use xda app set to dark theme..i thought the xda app the one that problem..not the phone...

Check it with the stock messaging app, it should have a uniform brightness. Mine is glowing on the left edge and especially on the bottom left corner.

You may notice that the black screen when you open the settings. Not symmetric Colors.
There is a difference in the backlight. Increase in the left of the screen.

AMOLED has no backlight! the issue is due to the production process (basically: the more of the center of the wafer your particular screen has been cut out, the more uniform it will be)!

If you want to get rid of display brightness issues, just switch to Dynamic, as the 'blacks' in Settings would be even blacker, to the point where it doesn't really light up as it uses the OLED technique of showing true black.

After getting it replaced now there are some vertical lines also as well as some horizontal lines.. so the previous one was better.. and after searching over net I found it as normal.. almost everyone has this in their device.. to get these lines visible u have to select a grey background and u have to check the display at dark room and with low brightness (25% or less).. I guess all have this issue more or less.. by the way I have asked for replacement once more.. lets see what I will get next.. but it is pretty sure that samsung should not invest on amoled technology if they cant produce error free display..
