Hi Guys!
Recently I purchased a 32 gb touchpad second hand dual boot CM9 and everything was working ok. Couple of days ago I noticed a four brighter spots-around 1mm- in the left top corner. I don't know if these spots have been there at the beginning as they are hardly visible apart from white background and other light colors. What I find strange is that these spots form a perfect rhombus, kind of the one Google put on the top dev apps. Could you please help me or at least give me some idea: what these bright spots might be? Thank you very much!
Can you provide a picture?
Have you tried any of the screen test app's? Could be dead pixels...

That is the best I can do. Sorry if the quality is no good. Although the screen appear grey it is actually white and those four bright dots are clearly visible. Thank you. I also checked for dead pixels, but I don't think this is the case. Appreciate any help!
This is a re-post of mishoni's image that he/she sent me via PM.

I'm not really that experienced with this kind of thing, but it doesn't look like a dead or stuck pixel to me. When you press firmly on the screen, does it change at all?
EDIT: This is a response from OCN after I posted your issue and picture:
"Look like a finger print
To ID screen issues make 5 pictures. They should be pure black, pure white, pure Red, pure Green and pure blue. Use MS paint ore something and its best if the pictures are the same size as the screen and in png format (Jpegs can have artifacts). Now look at thees pictures in full screen mode. If the "smudge" looks the same regardless of color then its probably something like a nick or scratch on the screen. If shape changes depending on color it means there are damaged or jammed liquid crystals in the screen. If the crystals are just jammed they can start to work again if you run flickering video (google dead pixel repair). If its indeed stuck pixles then you can also tap the area repeatedly as a slight movement in the screen panel can get crystals moving again."
You might want to give that a shot.
Hi Infinite Jest!
I installed Dead pixel repair and Pixel fixer. I run both apps and these spots are still visible, more or less on every screen background, apart from black. I don't think it is a scratch or nick on the screen, as the shape is strange and I cant feel anything when go over it with a finger. Also, the shape never change regardless of the screen background. I would appreciate if you could re-post to OCN-I don't know what that abbreviation stand for. Thank you again!

His response:
"In that case it sounds to me like its a back light issue or to precise the backlight diffuser has a flaw in it. The diffuser is an clear plastic sheet that's painted white. It's job is to evenly reflect the light from the LED's though the LCD matrix. Unfortunately there is very little a layman can do about an damaged/flawed diffuser. I would just try to live with it but if it really bugging you then you might want to either RMA if (if you have warranty) or ring up HP support and ask about what it would potentially cos to fix it (and that's probably more then you will want to pay)."

I broke my digitizer and LCD display and bought the replacements via ebay. Both were "OEM" or whatever.
I replaced them, and the digitizer seems to have worse multitouch than before. I understand that it sucks, but my 2 points never used to get confused when they crossed axis, (or so I dont remember them getting confused).
But also, my LCD seems to have a pink hue to it. I definitely know mine did not have this before the break. I read over a lot of posts here and elsewhere about the pink hue problem. This doesn't appear to be a browser problem, but an actual hardware issue.
Should I return the LCD and get a replacement and hope that the other one I get will be regular, or are my odds slim to none. My previous one was NOT pink whatsoever. And this new one I noticed it right off the bat.
N1 screen isnt LCD... did you get an LCD or an AMOLED?
Well it's LCD with LED backlight. I believe the company I got it from off Ebay got the OEM product directly from Samsung.
It is the same as the one I had before. The part number on the display is the same as the one on my original cracked one, 60h00287-00p

So the colours are a lot more bland and the black isn't really black? You would most definitely know if you got an LCD, it would look ugly compared to what you had.

Are you SURE its an LCD? as andrew said, the nexus only has an AMOLED screen which is a completely different technology
if it is indeed an amoled, then you may have gotten an ATT nexus amoled which is known to have a purple/pink hue
Well what I'm saying is the p/n written on both displays are the same, both from samsung. Which means, yes, it is a AMOLED display.
I don't think it's a case of an "at&t" display being sent to me. My nexus one was for at&t, and I didn't have such pink issue. But this new display does.

well china sells a lot of fakes and they can match up stuff like that.....
and not all nexus display this kind of saturation. Do you have a picture so we can see the extent of the hue?
it doesn't show up much in pics.
but I think it's beginning to fade. I've been leaving the display up with a red color. and alternating through white and black.
Here's a pic I took. But again, it doesn't show up much in it.

nah its noticeable on the keyboard and borders. use if for a while and see if the screen conditions itself. that is the same hue i believe that some att users were mentioning
It's worse to the eye than in the photo though.
I'll see if it fixes itself.
hopefully it just needs to be broken in
At 100% brightness, the pink tink is barely noticeable.
Actually, anything above 50% brightness and it seems fine. It's when it gets lower than that, it starts to look pink
Guys today i was outdoor.....i was using the phone in bright sunlight i could see some vertical dotted line(single line) which moves horizontally when i tilt the phone.......i'm wondering whether it is a display issue or because of the screen protector...............at indoor it is normal i dont see any kind of lines.......only when bright sunlight directly falls on it i am experiencing the issue.........please Comment thanks

if put extra protector on pre-installed one from sony that might be because of that.
if not i should say i didn see anything like this on any phones! (my experience)
and cause it has high density of pixel i must not have any effect or react on straight sun-light !!!
can u send pic ?

If u mean those colorful dots
SO it s not normal ask sony for replacement.
However u must not have any effect and reflect and ... on screen with high density of pixel.
It is completely normal, it's part of the touchscreen digitizer. It's visible on almost all phones under strong light. I could see it on my S, Arc (S) and Neo too.

LOL!!! Indeed it's the touch censor, that's how capacitive screens works! Don't freak out, every Xperia has it!
I got a moto X a week or so ago and have notice faint lines running mostly vertically but also horizontally in the display, mostly visible in solid grays and white. I did my research and know that this is an issue with the manufacturing process of this generation of AMOLED, but I'm wondering if this will be prevalent in every single moto x or if it's just that some are worse than others (worth an exchange?)? Coming from an HTC M8 on another carrier, the fact that these solid colors look so weird with the line running through them is very disappointing (otherwise I actually like the phone better). I'll post a picture when I get a chance.

That doesn't sound normal. I would replace the device asap.

I just filled my screen with white looking for these lines and couldn't find anything. Probably a defect. Contact Motorola.
Easiest ways see it is to download the LCD test app and display full screen gray. If you don't see it, then I definitely have an issue because it looks like a textured background rather than solid color.

Alright, thanks. Guess I'll be asking for a replacement.
Here are a few pics of my display for reference (hard to see on camera, but you can see cross-hatching in the lower area of the zoomed out pic and vertical lines in the close-up).

I found another forum describing it accurately as a linen-like appearance to the display rather than clear rendering. Very strange. In contact with Motorola now.

That's annoying. I may try to get one replacement to confirm this as I can't seem to find any display models locally anymore. I didn't like the display on my GS3 when I owned that and my latest foray back into amoled has been disappointing again.
Guys, its freakin me out , there is a strange cloudy like thick line that appears only on dark grey backgrounds the thick line goes from the very top all the way down to the bottom , dark grey backgrounds like when im using the Resurrection Remix theme,
so the line appears darker than the actual dark grey color, almost looking like blackish and its kind of annoying when i focus my eyes on it , i can clearly see it..
I have purchased my Nexus 6 off amazon in new condition the 349$ 32gig edition, first week it was wonderful.
this screen issue happened after the 2nd week .. and i babied it so i didnt drop it even once. hmm..
so i will give this another week and if the screen issue persists , then i will consider moving on from this beast ..sadly.
here is a picture of the actual problem.

"burn in" occurs when you have an asset on your screen for a long time, like the status bar. Then when you remove the status bar, it can still be seen slightly.
So what have you had on your screen from the top to the bottom for a long time that may have caused burn in? I don't think it is that.

RMA is return manufacturer authorization or something like that, basically return it for replacement. Are you out of warranty or just your location that makes it not feasible? If it runs vertically it sounds like a display defect. Burn in would show up where there is a static element for a long time, like the status bar.
Replacing the display might fix it, but would be costly probably.

appears vertically yes .. **** .. i hate white themes.. i hate the white backgrounds .. now i will be stuck with either full white or full black themes, cause that vertical line is seen on all other type of dark backgrounds .. just on pitch black and white i cant see it ... sad man just sad.
@danarama @akselic guys here is a picture of the actual screen.. so you might check and tell me if it is a screen defect .. that line only is visible on Grey colors .. Dark Grey colors, like the Theme i have on now. check it on the picture.

man first week ,totally in love with this beautiful beast.. now to bear with a defect screen.. just sad man uff
I'm not really sure what to call this, because I've never seen it on an OLED screen before.
I have the T813 WiFi model.
Recently, I've noticed, when using sites or apps with a dark background (like XDA Labs), that my display's brightness is noticeably uneven. Holding it in landscape mode, with the home button on the right, the screen looks something like this:
Bottom left corner: normal, full dark colors
Top left and bottom right: coloring is alright, but not as good as the bottom left
Middle (vertically): noticeably brighter, sort of a strip of washed out color
Top right corner: the worst area, looks like the pixels were burned
Excluding the strip in the middle, this is a pretty even radial gradient from the bottom left.
I can't really take a picture of this, because it just won't show up. I just have to do my best to describe it. It's almost like the backlight is messed up, except that OLED doesn't use a backlight. The pixels toward the top right are just a lot brighter than the ones on the bottom left, so they look whiter or washed out. It's somewhat strange. I've seen a few burn tests of SAMOLED screens (so Samsung) and noticed they turn white when heated and tend not to restore. I do put this in a computer bag, but I don't know what could be in here that would cause enough heat near one corner to do this (the CPU is top left, which is alright in color).
Has anyone seen this before? Should I get a warranty replacement? Do I need to describe it better?
if it bother you that much, just do warranty replacement.
my friend did it for his T715, the new unit look slightly better
but of course still no 100% uniformity.
Here's how mine somewhat looks (intentionally raised brightness to better show the effect. My power button also seems to stick a bit sometimes.

Yeah. After further testing there's definitely something I don't like.
Using the Display Tester app in the Play Store, I set the 4-gradient test to use the same dark grey color across the screen (1A 18 1A). Results weren't pretty......

Hmm. I'm kind of glad to see it's probably not a defect, but also kind of annoyed that it's normal. It'd be great if someone else could say if they have the problem too.
I have something like this to. Its annoying but only really visible with greys. Its relatively common with AMOLED screens, my S6 edge+ has it as well, but only very faintly.
