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.

There's a free app called Color Flashlight

Does seem that the blue and green work but red does not in that spot. Will contact samsung later to see what they say...

[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

Strange horizontal lines in HTC One screen.

Hey there,
I just noticed that on my 2 day old HTC One (FA35FW9#####, HTC_E11) has strange horizontal line on the screen. Even when it's turned off. It's visible on dark colours (black) when the screen is on. It's annoying. I tried to take a picture of it, but i don't have a lens that will focus on it. It looks like a solar panel of sorts.
Am I the only one that has this weird hardware issue, or is it well known?
regards,
X

Mine definitely has this, I didn't notice it until today outside in the sun. I don't see it at all when the screen is on though.

Hi,
I also see this on my HTC One grid when the display is lit on a black background and there is sun. Is it normal, everyone does it ? Or is it a fault and should it change ?

It's on mine as well...can see it under a very bright light...but not normal conditions...... Think it's the digitizer !???

I think its just the screen. I get it under sunlight when the screen is black. Little annoying but i'll live Anyone else with this?
I find they look more like blocks though...

Do a quick search of the forums. There's MANY of this exact topic, and all have been resolved.
It is the digitizer by BTW...

Hi,
Thank you for your answers. So what is normal ?
Because I saw two other HTC One grid and it was much less visible than on mine, we only see screen off when the mine can be seen when the screen is turned on if the sun on the screen.
Do you think he should return it under warranty ?

Apparently the screens made by sharp have more visible lines than the ones made by JDI, but there's no way to know which is which without running an app to retrieve the information (or maybe viewing the screen under sunlight ). I can see the lines on mine but since I don't look at the screen when it's off I don't really care about them. You'll never find one where the digitizer is invisible, and buying a One is gambling on getting a good one vs build quality issues, so if that's all that's wrong I'd just hold on to it if I were you.

Horizontal lines approx 2mm apart are visible on mine too when screen is off...Noticed after 3 days i got it and was not sure if m i the only one who got it, untill i found this thread. I dont mind those lines if they are there, but it doesn't call for alarm right??

Same
I've had this on two HTC Ones, so I think its normal. I also found that its only really visible when the screen is off.

Same here. Maybe because the pixel technology... Someone better in techs can say maybe.
Also if am right there is same question and discussion about that.

Just the digitiser in the screen. It is visible on all HTC Ones but, as said previously, a little easier to see on the Sharp panels.
Nothing to worry about.

Yeah i just noticed mine today when i was outside in the sun... :/

I just noticed this on my way to work this morning, now I can see it almost all the time whenever the screen is off or has a dark backround, for example I see it with the phone laying flat on my desk directly in front of me, what I would consider a normal viewing angle with the screen off or on with a dark background.
my phone is only 11 days old should I contact my carrier regarding this??, its kind of annoying.

No, it's normal and not annoying. You shouldn't be able to see it if you're looking directly at the phone.

Thanks for the reply, it does bug me a bit like but I guess I could live with it.
It is quite easily noticible from slight angles but not if I am looking at phone straight on. I have a couple of friends with the same phone, I will check theirs to see how visible it is on their handsets.

Want to get even more irritated with it? Pull up a white background, like in the text message app, stare really intensely at it, and you can see the lines very faintly and what appears to be a texture similar to cloth, not a smooth-like-paint texture that would be ideal.
Once you notice it, you'll always see it. Lol. Have a nice day!

OMG you bastard! :laugh:

I just noticed that my ps vita also has these lines, but it's a grid instead of just horizontal lines. Different screen tech but similar digitizer I suppose. I chuckled a bit when I saw it for the first time

Xperia Z1 dust under glass or dead pixel?

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.
