Xperia Z1 dust under glass or dead pixel? - Xperia Z1 Q&A, Help & Troubleshooting

Sony wants me to send the phone in, but i cant tell what it is, i dont know if i should send it or not, they dont cover shipping charges.
does dead pixel appear pur black or a multi color dot?

Dead pixels are white/black and stuck are coloured.
Use the current camera, zoom in so you can see the pixels, should be easier to determine what it is.
Either way I think you should send it in, that would drive me crazy.

See if there's an app on the store to test your screen by cycling between colors. Like the poster above said. If it stays black on all the colors then it's dead. If it's stuck on a color you will see it dissappear on one or more of the backgrounds.
If it's stuck you can try "stuck pixel remover" which will rapidly flash between colors and might be able to fix it. I've managed to do that once on a pc screen for a client. Good luck!

The one I sent back has a stuck green pixel, and pixel fix app didn't fix it. So the best way is send it back for replacement.

Dead pixels?

Anyone else experienced dead pixels? Looks like I have a couple dead in one spot or at least one color is. On solid white shows light blue.

Dead. Call att/samsung
Yay no more fc
Sounds liek a stuck pixel rather than a dead one to me, I thought if they were dead they'd be black. Are there any apps in the market that will quickly flash different colors on the screen in an attempt to unstick them? That worked on my iphone before. Also what I've done in the past is put slight pressure with your finger on the screen where the pixels are, sometimes that will make them go back to normal.
Dead is black, stuck is green/red/blue.

[Q] URGENT HELP~~~Are These Dead Pixels???

Hi Guys,
After hearing so much problems with the Note screen, I had another good look of mine tonight and found these weird looking white lines/dots at the bottom left of my screen.
Are these dead pixels or stuff underneath the screen?
HELP Please.....might have to get an exchange with handtec...so much hassles....
Those look like stuck pixels to me.

You have taken a pic with the default scratch guard on just remove and slightly clean the screen and see if it goes away, but most probably its 2 dead pixels, mine 1st one had 1. Quality issues with samsung !

I'm pretty sure it's not between the screen and the default protector....where did you buy yours from?
Seriously...I'm very disappointed with Samsung now....I mean, I have heard many people having problems with their screens, but never thought I would get one of them defected ones....
Looks like dead/stuck pixels I'm afraid.
Can you get a macro shot? It's kind of hard to tell without a closer view. When I've had stuck/dead pixels in the past, they've always been very discrete, tiny dots without any haze or blur, which it looks like yours has. I also wonder if it's something to do with the screen protection film. When you do a macro shot will you lift it and clean the screen?
Here....I have lifted up the screen protector....I didn't take off the screen protector was because maybe if I didn't handtec might exchange me the phone quicker....but what the heck...I need to be sure anyways...so here are the pictures.
Man.....so much trouble for this phone....very disappointed with the build quality of the screen now....
Now I will have to wait for a while to get my exchanged new phone ....
Any ideas how long it might take? I read on handtec that if the item is returned after 10 days...it will go under warranty and so does that mean they won't exchange my phone straight away??? Anyone got any experience with them??

nuh...I have tried to count them...there are a least 4 dots plus a line....very strange....they are also bright green instead of being white.....can't see them with the black background....
Shows you how bad of quality the phone I got....
I am very surprised I have not noticed them before.
Just found out online...there is a difference between stuck and dead pixels, and apparently stuck pixels can possibly be fixed yourself...might give it a try....
nuh...none of the apps seem to work
Been using JScreenFix for the phone for about half a day....just flashing the screen.....
I think the pixels have gotten a bit darker......don't know if it's my eyes playing tricks on me or not....but will continue to flash the screen for the rest of the day and then check it again tonight....hopefully then will be gone
The thing I don't really get is why the green dots (more than 3 of them) would only appear on Green, White and Grey backgrounds, and not appear on the Red, Blue and Black Backgrounds.....Anyone got any ideas?
because every colour of the spectrum uses green except for red, blue and some combination of red blue
black is when the screen is off

Hi there. I just bought the Note few days ago and I can confirm that I have the EXACT problem as yours. Except mine is just a dot. It's like a pixel that seems to be the only brighter pixel when the screen displays full green, white or grey background (specifically used the LCD test *#0*# & Burn-In Tester Pro app).
I assume that it is a stuck or a hot pixel simply because.. it lights up. Unlike dead pixel is like.. a dead bulb/pixel (Assumptions. HEHE.)
Actually on the day that I bought the Galaxy Note, I was really careful. I even dialed the *#0*# LCD TEST at the shop to look out for screen defects. It was FLAWLESS. So I bought it. And I have this habit to look out for defects even after purchase, so I always go to the LCD Test and Burn-In Tester Pro app to check, and is still perfect.
Not until, last night, I dialed *#0*# and hit "Black (Vibrate)" with the intention to check for the "blemishes/blobs" in a totally dark room. It was only apparent after my eyes had adjusted to the darkness and I do see the not so obvious blobs. So after noticing that, it didn't bother me so I happily watched an Blu-Ray quality video (Despicable Me) and that's when I noticed the BRIGHT pixel which I assume it to be a STUCK/HOT pixel. I hope it is just a stuck pixel which hopefully can be fixed over time. Don't know about hot pixels..
Right now I'm playing a Full HD video of a downloaded YouTube video called Pixel Fix, on loop, with Video Brightness set to full. My instinct says to try it out but i do know that after awhile, since it's an AMOLED technology, colors could be darker over time as the pixels slowly 'burn-out'.
AND if it doesn't work, I might try to turn off the phone and leave it somewhere really cool/chilled. And switch it on after awhile when it reaches room temperature. I read it somewhere that it works to remove stuck pixels. They put their phones in a fridge in a wrapping and they said it worked. I forgot though where I read it from.
Oh, it's this one --> http://forum.xda-developers.com/showthread.php?p=21025093
Someone managed to fix a dead pixel. Hmm, but it's a phone with an LCD screen. Nyeh.
Good luck to us. Man, it was only few days ago when I bought the Note. *sniffs*
Seems quiet here. Seems like not many people have or aware of this bright spot defect.
But I found this which seems to concern about the matter. http://www.patentgenius.com/patent/7955151.html
I guess it gives some idea of what it really is. Cheers.
And I am gonna let this 'problem' go this time cos it's so small but I do hope that it won't get any worse. Or if it fixes itself that would be a miracle

Problems with display(?) in some apps?

So if I'm in gmail, facebook, google services, and other (white background apps) i see a yellow spot on the center->bottom of the screen. The wierd thing is that if I make a screen shoot..I see it also on the picture!
if in the first picture you dont see what exactly I mean..in the second one you'll see the area where is that yelllow spot(big).
What could it be and how can i repair it ?
If I'm correct, it looks like finger press impression on lcd screen.
Btw did you drop your phone recently?
You could try repairing your phone through pc companion., though I doubt it'll work.
Final option would be taking it to sony service centre.

Both of these explanations dont explain why it appears on the screen shot though.
The screen shot should be of the screen as it should appear and not take into account a screen protector or damage to the screen.
If I am not mistaken a SS shot does not take a picture of the screen, it just records in memory what the screen should be showing so a damaged screen will not show on a SS.
Anyway apart from that I am unsure on further causes.

Point! The SS should not be affected by physical alterations.
If software-wise I think it might have something to do with color balance or contrast ratio.
and how can I resolve this software issue ?
the contrast issue ? because for example if I go from a dark screen to a white one...i have to wait like 1-2 seconds until the contrats it's OK! :-s

If it is a dead pixel it would just show up as a small point of light when you first turn on the tablet. It would also more than likely not be noticeable when Android loads. Dead pixels cannot be repaired. You would have to either send your tablet back to Asus to get the LCD replaced, or if you just purchased the tablet, contact the retailer to see if you can exchange it.

I've got 2 issues like theses...
The first one:
- I've carried the tablet in my bag and there was pressure in the center of the screen. When i taked out the tablet there was a circle in the center of the screen about like you. After that the circle began to slowly smaller and smaller, until it disappear.
The second One:
- My 1st tablet got a yellowish spot when it was brand new. on white background i was able to clearly see it. I realized that the screen toched the back on this point. If i pushed a litte bit on the glass at this place, the lcd became fuzzy.
So bad quality issue Asus...

Your LCD is broken, I've had the same with my TF701. I've contacted ASUS and they replaced it for free.

Green tint when N6 is tilted

Guys I'm noticing this green tint on the glass/screen when the phone is tilted. Its green from all the angles, only when you look at the screen head on you see white. So all whites appear to be green when phone is tilted. This thing is screwing with my eye when I shift from PC to N6 or TV to N6.
Only at extreme angle the camera that I have is able to capture that green tint but to the eye it is visible at the slightest tilt.
Wanted to ask you if you'll are noticing similar issue? Can you please check, post pics from diff angle or even upload a video. It would be very helpful as I can go ahead and consider a replacement if the unit is defective.
Video (sorry about the quality)
https://www.youtube.com/watch?v=KFXjRy2sDUk&feature=youtu.be
The verge review mentioned this, mine have it but less noticeable, also didn't bother me at all, I never look the phone at that angles.
this is just a normal amoled thing i believe, my device has it too
Normal for AMOLED displays.
So what do you'll think? Should I ask for a replacement as it is more noticeable then the rest? When I'm on the PC and the phone is sitting on the desk right below the monitor from this angle the top half of the screen is green and the lower half is whitish. Is it normal in the case of amoled displays? Again this is my first device which has an amoled display, never used one before so my eyes may take time adjusting to it. I'm just worried about the unit being defective.
Check the screen for pink and yellow tint, there is a forum about it. The green/blue shift is normal as the nexus 6 uses last generation amoled screens like the ones found on the note 3 and galaxy s4

Is this the yellow pink tint you speaking about? Didn't notice this thing until you mentioned. I think a replacement is needed ...what do you say?
First pic is at max brightness adaptive display setting turned off.
Second pic is the wallpaper I used
Third has brightness at 50% adaptive display setting turned off.
My Nexus has a pink patch on the screen so I'm going to get it replaced but people are saying that it is a lottery and you might get a worse device.
Give it a try, you've paid for the device and it is your right to receive a device without flaws
