[q] dead pixel

Hello Atrix users! Im not sure about your phone experience but coming from rooted lag fixed 2.2 Captivate (highest quadrant benchmark 2004) i have very positive thoughts about the Atrix. So far i only run into audio playback problem that appear to be the auto -kill check list and is easy fixed by unchecking certain apps and folders , check my findings searching my responses to posts if you having this issue. Till today i was nice and happy till i spotted dead pixel. Im sure wasnt there when picking up from store ( i have 20/10 vision yeah my eye doc is confused too). I wanna know if any of you noticed dead ones after few days of use . If you do im questioning the quality of this display because besides stating its first qHD we dont know jack a... about it.
exchange it at a store
if they dont let you , best bet = take it to a store for a full refund
then buy it at another store
I'll check this post for few days and see how it goes. Its not that big of a deal but just wanna see if any others having this issue. This way I could back this up talking to them in store.

Ok this really weird day for me officially saying goodbye to atrix . I posted before about exchanging the dead pixel phone . Coming home I discovered the screen way off alignment to the left and actually twisted sideways . I got really upset and got back to store . They pulled 2 more for me , first one had the same problem off to the left and twisted second oh guess what dead pixel. I can't believe that posting about overall good first experience I found this phone to be such a poo build . I think Motorola totally paid individuals who made first reviews before ATT put them in stores. New dual core technology into something this cheesy its a shame . The guy serviced me today said I'm fourth person returning this phone due to problems with the display . I'm officially done with any Motorola product. Compared side by side with HTC inspire 4G didn't performed any better , even my girlfriend noticed that the HTC its much smother and actually faster opening applications not to mention build quality. So after all this drama I'm looking on big 4.3 screen and thinking I made damn good decision .

Stuck Pixels?

I have around 4 stuck pixels. They show up on grey screens as little light dots. Gets kind of annoying watching movies when and such. Tried the jscreen fix from the market but no luck.
Is this pretty normal? What's Sprint/htc policy? Just wondering if every phone has a few. Thanks in advance?

Take it back, tell them you want an exchange due to screen defect. If it's one lone pixel I can see it being dismissible but a cluster is not good.
In the general market they usually have a dual standard.
up to X amount of pixels bad is considered within tolerance however if the pixels are adjacent then the threshold is lower so it would fail quality control.
If they give you grief just ask for a refund and rebuy it
Take it back. Its defective. They will replace it

i turned on camera in dark room and i see like 3 pixels blue/green
has anyone tried that?
i tried my friends , turning on camera in completely dark room and didnt see any pixel issues
I have found from all these devices it is pretty common to see a stuck pixel here and there. I think you have to decide how bad it is or isn't. Sure you can exchange it but then you have to keep worrying if the next one will be worse and it will then become a never ending cycle!
this is true

Curious what you re going to do? I have 1 tiny one on the side of the phone that is only noticeable in a dark room on a black background. On the fence on what to do....I went through this with my TP2 and went through 4 phones and ended up keeping the best one of all of them but still had a stuck one. Just wasn't as bad as the other 3.

That program didn't fix my issue and with the other program I noticed a total of 4 all generally in the center of the screen. I am going to have Sprint exchange and see what happens on the next one. Since yours is in the corner I would let it slide.

I had to do this yesterday and they gave me so much trouble about having a dead pixel. Yeah, it is pretty particular to complain about but didn't we buy a brand new phone?!
I bought mine online, so I am not even going to deal with the store.

Good idea. I stopped by the store today and they just about laughed me and my 5 stuck pixels out of the building.....tossers.
They ran a "test" and said everything was fine and a few stuck pixels were fairly normal. I called sprint and they offered a new phone that should be here Monday. Kudos to sprint!
Hopefully the new one doesn't have the same problem.

Dead pixel

Ok I think I have lit pixel. When I lower the notification bar over the home screen I get bright white lit pixel on the lower right of the screen. It's only noticeable when I lower the notification bar and not on any other black screen. Anyone with this problem?
green pixel
I have single green pixel here. Like you, it only appears against a dark background and it's located in the bottom-right corner. Best Buy didn't have any extra units for replacement but assured me that next week I'd receive a replacement if I just brought it back in. My OCD has kicked in though and it's bothering me more each time I see it!
Yeah I have a dead or lit pixel. Its white on a black back ground My Best Buy had extras that they couldn't sell but I'm guessing they could do a exchange so I'm not that bummed out.
Looks like HTC did a good job of this not being a big problem, base on the lack of dead pixel threads.

are you kidding me!! for the past two weeks ive been trying to get a flawless phone ive been to 4 sprint stores, all the evos id seen had dead pixels, so i dont know what are you talking about, i am really frustrated with this phone and htc for using cheap screens on this device, I bet most of you do have a dead pixel, download the detect dead pixel app and youll see
Wow... maybe its just me. But I think exchanging a $600 for a dead pixel is a little too excessive... I have 1 dead pixel near the bottom, but it doesn't really bug me that much. It's gives it some personality =D
Dead pixels have been a problem with LCD technology since the beginning and these screens HTC are using are anything but cheap quality. This is simply a recurring issue with LCD's in general.
I'm not saying you have to deal with it or that you need to stop being so picky. Hopefully you find the perfect phone.
And FYI I don't have a single stuck or dead pixel and I bought this phone off of Craigs list. It was a roll of the dice and I got a perfect defectless phone.

ive had dead pixels on lcds and phones before, over time they do come back to life.
pointless taking it back unless theres a cluster of dead pixels in one spot.
I am on my third Lte because of dead pixels. The sprint store didn't like me when I came in to replace the replacement because of the same exact problem. I told the salesman that I had paid full price and I would not stand for a defective product. I told him look at it this way, would you buy a brand new car with a dent in the door without them fixing it before you signed the papers? I think not. People should not stand for anything less than a perfect phone when it is brand new. If HTC and Sprint had better quality control then I wouldn't have had to return 2 phones.

I had a dead pixel right in the middle of the screen. I thought I could live with it until I tried watching a movie. It looked like a baseball floating in the middle of the screen. If I am renewing my contract and buying a $600 phone, it better damn well be perfect. There is no reason to accept a phone with a manufacturer defect if it bothers you, regardless how small.

yeah you are very right we deserve premium quality for our money, thats why i wont accept a single dead pixel on my screen , i will keep returning the phones until i find one without it, but i have almost given up, since i have been in all store around my area, checked 14 phones all of them with dead pixels, maybe im just lucky lol. damn i hate my luck
Yeah I see the dead pixel in the lower right now as well. Who made this thread? There about to get a beaten hahaha
I'm j/p, it not bad at all tho. But over time they def can get worse. But till then, it doesn't bother me. And I'm a nutt case when it comes to my phone

I made a dead pixel video of my Tegra 3 version. Soon as I get some views/comments, I.e. some leverage against HTC, I'll try to ask for a replacement. If not then I'll settle for a repair. Hope this works

dead pixel

So it appears that I have a dead pixel. I can't really tell. It's definitely not on the surface, so it's either dust underneath the screen or its a dead pixel. But it's a very very tiny black spot, right on the white part of the clock on the homescreen. Should I take this baby back? I can probably live with it for 2 years...i guess...it's just knowing it's there that bugs me. There's no danger of more dead pixels is there? Is one dead pixel indication that more may happen?

Run the app for 1 hour and that might fix it. It has worked for others.
Dumb question: is there any danger in running the fixer for that long?

If you look right at it you could suffer a seizure.
If the pixel is the only screen issue I'd say keep it. Swapped mine only to get one with a dead pixel somewhere else and now I also have the dreaded yellow cloud towards the bottom of the screen. So count yourself lucky if that's the worst of your problems. Take care.

I was thinking the same thing. The way the OP explained it, it sounds like it's not even noticeable. BTW I was told that yellow cloud will improve as time goes on.

Yellow cloud?
I've heard of these dead pixels and light leakage issues. I don't see any dead pixels, but I work nights too so my phone is always at lowest brightness setting.
Think if I knew I had one it would drive me crazy staring at it, lol. Anyone have a pic of what one looks like, maybe zoomed in?

Judging from the review on the market, NO. But, I haven't used it personally. however, I would think if something bad happened, you would see a ton of bad reviews talking about this.
HI, I just wanted to add something to the list of problems that the new evo is having, yesterday i went to the sprint store to buy an evo lte, but i couldnt take any home, since all of them were plagued by dead pixels, the sprint rep open six boxes and all of them had a least one dead pixel, I went home very frustrated i cant understant how HTC uses cheap screens on its premiun devices, I am one of the guys that cant stand to know to have a dead pixel on my screen, since once you know its there is a pain not to look at it. So i will keep going to every sprint store until i find one with no dead/stuck pixels. It may take months but ill be worth it. I personally suggest and encourage that you guys download the app called dead pixel test, and try to find any dead/stuck pixels on your screens if you do find some, take your device to sprint and return it, and get a new one without any deffect, lets make htc to stop giving us cheap quality parts in our premiun devices, we are paying a lot of money so we deserve to have a device with not deffects. I can understand a dead pixel on a tv screen because is big, but on a small screen is unacceptable!!!. Please tell me what you guys think about it, and please bear with my english since is not my first language. Thank you

Dead pixels and LCD screens go hand in hand. Its the nature of the beast. Just wait and see when the GS3 gets release.
I noticed last night that I had like 2 or 3 dead pixels
i can probably understand a dead/stuck pixel on a big screen but on a small screen is just unacceptable.
JFYI, I ran the dead pixel test on my old 3D and had some obvious ones on that phone, but I just ran it on this one and what I thought was a dead pixel was just a speck of dust. Kept thinking I was seeing them and kept being able to just wipe them off. Sounds dumb but try it.
well my experience with this phone has been a nightmare i have been to 5 sprint stores around my area including best buy, and i have checked 24 htc evos lte and all of them had a least one dead pixel on then, im really frustrated with htc for this, i really like the phone but im starting to think that all of you phones have a dead/stuck pixel as well but you havent check it throughly. i really want a evo lte but i not longer wish to fight with the sprint reps for going over and over and keep returning phones for this. i am not crazy maybe im just having bad luck, but its embarrasing going back to the store and all the reps looking at me like (i dont want to sell you anything), oh i really hate my luck. but i hate htc the most for using cheap screens on this phone.
Wow, I have a slight bit of the yellow cloud toward the bottom of my screen, and I thought about going to try and swap it... but from what I'm hearing about the amount of devices out there with dead pixels, I think I'm going to keep the one I have since there are no dead pixels on it. I've checked.
You may want to report these issues to Sprint either by calling them or by posting on their forums.
I guess I'm one of the lucky ones. My phone doesn't seem to have any issues at all. Curious to run that app, but don't want to be disappointed and find something wrong with my phone,,,

Love the phone but it has dead pixels

Got this beauty on launch day after calling up about 10 different tmobile stores!
I love this phone and its killing me to have these dead pixels especially because one of them is in the damn middle of the screen, the worst part is that it is sold out everywhere where I live so I cant even exchange it.
Get your **** together HTC and don't let your customers go through this frustration!!!
That sucks.
Hope when I get mine I don't have any issues like that.

I thought the same till I ran the dead pixel test.
Anyways i'm glad for you enjoy it, its an epic phone!
So hold on you was happy with your phone until you ran a test that told you had a dead pixel? Sounds like nitpicking to me!
I also have couple of dead pixels, only saw them when I ran the dead pixel app..otherwise can't see them...
I feel some are just reaching to find a issue with there phones. It would be different if it affects anything but if you can't see it and everything us works ok just be happy with your phone.
How about people stop making threads complaining and just exchange their device.

So I just noticed I have a dead pixel as well. I'm within my 14 day period but I unlocked my bootoader. Does anybody think I will get a problem from HTC when they get it back? I know they won't notice in store.

I had 2 stuck pixels on the bottom left corner of my screen, but I noticed one day they both went away.
Got mine a week after launch. Cant find any dead pixels. Are you guys going to exchange your phones?
If I had a bunch in the center of screen I'd replace it. If it's the same as my One X and I just have 1 or 2 in the corner I'd probably keep it.

I made an exchange, second unit has one dead pixel on the top left but I decided to keep it.
Mine had a piece of dust inside the digitzier assembly. Ironically it was not able to be shooken out due to the "goo" that is placed in the gap between the digitizer and the LCD to prevent dust. I went to exchange it and I am fine now. I was pretty bummed out because my girls didn't have any flaws lol.
I have two stuck green pixels in the middle of my screen. What's weird is that you can only see them in the dark. I ran a stuck pixel fixer to no avail.
It's past the 14 days and I bought my phone from eBay. Does anyone know if T-Mobile will replace it? If not, no big deal. I can live with a few green pixels. Plus it's rooted, so I don't think they'd replace it, even though it was there before rooting.
I have 3 dead pixels on my phone. I was at day 16 when I noticed it and T Mobile is graciously exchanging it for me.
Will they replace it if it's rooted, or should I un-root it first?

I would definitely un root the device before sending it back. From my understanding you can't re lock the boot loader so that is really just a crap shoot if you get a tech that actually checks those things.
