Stuck/Dead pixel anybody else?

Noticed today that my one has one stuck green pixel and one dead black pixel within about 1/8 inch to each other..... Kind of sad becaus i purchased the phone from kijiji and have no warranty...

Just wondering, isn't it terrible difficult to notice the state of one pixel on a 1080p 4.7" display? Isn't it a group of pixels?

I opened up a brand new 32gb T-Mobile M7 and saw these marks, not sure if dead or stuck pixels as they only show with light colors (most prevalent in white)
It's the pair of dots that almost look like a distant light reflection, bottom right corner of the screen, each cluster is nearly a mm in dia
They almost look like nicks in the between the touch panel and lcd

When i got the phone 3 weeks ago i noticed one green pixel on the screen cursed my luck and promptly forgot about it. I only remembered last week and checked and its gone. So it obviously wasn't "dead" at all just stuck. I never ran any program to get rid of it or anything

I went through twelve units (not only because of screen issues) and for me one thing is certain: There is no ONE without pixel defects. Just depends on your surroundings if you see them and how closely you're gonna look for them. This one has four green ones visible on black backgrounds. If you watch closely you can see the area around them flickering in every color. But I keep it since it's the best one and those pixels are rarely ever visible under normal circumstances.

I bet mine has also dead pixels. But take a look at the pixel density, what would a dead pixel matter?

I was just as pessimistic as you, regarding getting a screen with no pixel defects. Fortunately, I did swap my One out and this one has zero stuck or dead pixels (used a pixel testing app in complete dark -- believe I'm OCD and looked extremely close to the point that my GF was questioning my sanity). So getting a good panel is, indeed, possible.
BUT, this handset does have a hot pixel on the camera sensor. Go figure...

[Q] Faint grey lines across screen.

Picked up my HTC One today and loving it so far, except I've noticed one thing - faint grey lines running across the screen, most notable against a white background (my attention was drawn to them in 'settings').
Others have reported it with no real conclusions being drawn:

Any idea what these are, are they the norm and what causes them? Should I attempt to swap it?
Thanks for any help.

How faint? Could be the touch-sensor.

I'm not sure how to describe how faint they are, they're not hugely noticeable and appear evenly spaced.

I think your seeing the backlight lines ..... which you notice lets for e.g when you open chrome browser to an emplty white page. right?

Same lines as keyboard flickering that you see out the corner of your eye? I feel like I'm trying to catch the elusive Bigfoot catching the keyboard flicker, but it never happens when I glaringly stare at the keyboard!

Yeah, I can notice them fairly well on a white page in Chrome. Is it normal, or a defect?
Thanks.

normal for back lit screens .... this is one reason i miss Amoled ..... deep blacks and no back light unevenness.
You see these stupid faint lines on $2k retina macbook pro too !

Right okay, they're not so much a hindrance I just wanted to make sure it wasn't an issue with my device alone. Thanks for the help .

I do believe this is the backlight lines as mentioned above. I noticed this once while outside on a sunny day while checking for scratches, not visible on regular use though.

man i thought it was my eye! lol i did notice the keyboard flicker once or twice. did not pay much attention as I was sleepy and I thought it was my eye

I have this too, it shows clearly when I'm in a white page or white color background. I hope that this is normal like someone else mentioned that this is just lcd backlight not just some batch. I hate to go through the hassle of calling them up and return it.
please post here if you have these issue too, so just to verify that this is normal.

Yeah on a white background I have the feint grey-ish lines. I think it's the digitiser.

Huh, interesting! I've never seen that before specifically looking for it but yeah, there they are. Boy are they faint though... Like you have to really look for them and have a PURE white background (for mine at least)
They do indeed correspond perfectly to the digitizer lines I was looking at on my phone earlier today ironically! If you tilt the phone on an angle under bright sun light you'll see the horizontal lines of the digitizer under the glass which match the locations. I can't imagine them being related to the backlight though because you can't see the physical structure behind the LEDs when they're on. Try seeing the back inside of a light bulb when it's on ).
Worry not I'd say.

Basically it's nothing to worry about. It's a small disturbance which is needed for your touch screen. If only they could intergrade this better like AMOLED screens do .
Definitely NOT a deal breaker!

It's definitely a deal breaker for me, I never had this kind of problem with my past phones that I used, including Iphone 4, iphone 5, GS2, GS3 and Galaxy note 1. They all have beautiful perfect screen, no smudge like brownish or grayish line and never have any problem on hardware side whatsoever.
Only with HTC One that I exchanged 3 time and still have the same problem and come with an addition of stuck pixel. Don't get me wrong, I truly love this phone, but this is too much for me, I feel like going backward if I were to use this phone daily and pretend that it's normal. they need to do something with their QA until then I'm done with HTC.

For those who are seeing these grey lines, how are they oriented on your screens? Mine has diagonal lines across the entire screen, which seems really odd to me. They're especially visible on white and light backgrounds. They almost look like fingerprints, excpet that they're under the screen surface...
The thing is, this is my second One (returned the first due to stuck pixels) and I never noticed lines like these on the first one, even though I scoured the screen very closely looking for dead/stuck pixels.

The are horizontal lines. The thing is when you are looking for a dead pixel you will not notice the lines. Look under a bright light you will see the touch sensor under the glass .

I can't see any lines on a white background. Digitiser lines are visible, barely, in bright sunlight at really harsh angles. I'd take this over the burn in and ghosting present on all AMOLED screens including the GS4 , any day of the week.

If you never had screen issues on SGS2 and SGS3, as well as galaxy note 1, then you are extremely lucky, and now you are extremely unlucky to have issues with the ONE. Burn in and ghosting is present on all samsung amoled displays.

Yeah, that's different from the issue I'm having then. The lines I'm seeing on my screen are visible on bright backgrounds and like I said, they're diagonal.

[Q] Blacklight visible from screen edges

Anyone else experiencing visible blacklight from the screen edges? I have a very pronounced strip of blacklight coming from my right hand side when viewing bright content from a slight angle. Compared to the other side, it looks like a defect.

Pictures below

It`s totally normal the led`s are not on the back, but on the side of the screen and a light guide channels the light across the screen, this is what happens on every lcd screen, the word back-light is an misnomer.
EDIT: so the white led`s are at the right side of the screen and light goes across the screen to the left side, that is why the light does not show on the left side as much.
But the light should not be excessive., if it is get it replaced.
John.

Yeah. I know that this is how edge led lit LCD's work. But does every H1 owner have this clearly visible strip along one edge?
I can see it to a much lesser extent on my father's H1.
My old HOX does not have this at all. The HOX screen even looks better as it seems like it is floating on the glass surface!

I have check my One five times for dead pixels and for backlight leakage and i saw nothing.
I just checked for backlight leakage again using lcdtest at full brightness though all the colors, and mine is very very slight, really nothing at all
Yours is quite bad, if it`s bothering you get an exchange, but you dont know what you will get.
EDIT : I had a HOX and the display was perfect, but after 2-3 days i had a yellow patch show up, and i returned it and got an S3 instead.

Thanks. Anyone else care to check their screens? I have the opportunity to send it in for a repair, but unsure if I want to be phoneless the next few weeks...

[Q] Anyone else have parts of their screen with red tint?

Here's an image of my first Nexus 6 (top) and the RMA replacement (bottom): http://i.imgur.com/wNbgFo1.jpg
As you can see, my first N6 had a pink tint across the whole screen which is why I initiated the RMA. While the replacement is better, there's still a red tint to the right half (bottom half in portrait). Actually looking at both, the reddest tints are in the right half.
I also have some bands that are dimmer than the rest of the screen which is very noticabke when scrolling but not so much if looking at a static picture.
It seems these really are using Note 3 Samsung AMOLED panels because the same complaints were posted on another thread last year.
Both devices were manufactured 11/12 if that makes any difference.
I'm just wondering how common of an issue this is. I don't think I'll RMA again for awhile as I'm just taking up devices that should be going towards fulfilling orders and my replacement is serviceable. But considering the price, I really expected better and I don't think I can stomach the flaw.

You answered your question (the very end statement). I can't really see what you're trying to show in the picture as everyone see's colors differently and not all phone displays/pc monitors are color calibrated in the same ways. GL finding the right display for your tastes. They all have compromises albeit some less than others

You don't have to have a calibrated screen to tell that the top screen is darker than the bottom screen. It's also not hard to tell that the left is lit brighter than the right on both. Whether you see pink or not may be arbitrary but that's why I put it in the description.
My original question of if anyone else is having that issue is not answered just because I found a thread on a year old phone that may or may not be using the same panel Would prefer if other owners chimed in so I don't waste my time RMAing if it's unavoidable.
But thanks for the reply.

I have the same problem, the upper part of the screen has a pink Tint and it's bugging the hell out of me, but since i've had my friend bring it with him while coming back from USA, i'm obligated to swallow up whatever defects i find in it

My mistake. In your picture it looks like the right side of both screens is a little darker than the left.
That said, and you don't have to answer these I'm just thinking out loud here, what were your camera settings when you took the picture? What camera did you use? What screen brightness was each display set to? Could the ambient lighting in the room have affected the photo results? Could there have been inconsistencies in the results caused by the angle of the photograph taken? Those are a few of the variables that I can think of that could skew what we're all looking at.

I used a Sony NEX-5R Mirrorless DSLR. I probably didn't use the best settings (automatic with manual focus) but I was kind of in a rush to get the old one out to UPS to get the CC hold for the new one to drop off. I didn't use any special lighting, just natural day time lighting. I think the pics are pretty representative of how tinted they were though because the old one was very red heavy everywhere. I should have taken additional pictures of the home screen to compare. On the default background, the new one looks turquoisish but the old one was dark blue.
Brightness was at 50% for both and I believe I had adaptive brightness turned off. Either way it was light up much brighter than I keep it at day to day (I usually have it at 25% at most with adaptive brightness on). If I had to compare the pictures to the actual devices I'd say the camera didn't pick up enough of the red tint. So in person, it's much more red and much more obvious.
But honestly, I don't care that much about the tint as much as I do the uniformity. I can live with an all yellow tint or an all red tint if it was consistent across the whole screen. I'm sure a custom kernel will come out at some point with gamma calibration so I can adjust as I please. But the way it is, the top half of the display looks brighter than the bottom half. The easiest way to see this is by setting the keyboard to Material Dark and putting the phone in landscape. The left side of the kb will look greenish grey and the right looks darker purpleish grey.
I've not heard anything about this issue. Maybe one or 2 posts on here and reddit regarding banding. Everyone else says their screens are perfect. I was hoping people would share their pictures so I can tell if I got 2 bad screens or if they're all like that and most people just don't care.

I can see the light / dark difference in the screen with that image, but it doesn't bother me across such a dark background because it still looks grey all over (just to different degrees). I actually find that it's much worse with light backgrounds because it doesn't look all white or light grey. The darker parts are always pinkish. It also doesn't help that Lollipop is all about white screens everywhere either
Also found out that I don't qualify for the extended holiday return, so I have until Friday to return it for a refund. I guess I'll be calling for device #3 earlier than expected and crossing my fingers.

My note 4 looks similar to ur replacement device, the first 2 were really bad,half of bottom was really pink,2nd one the top half was really pink..This one I'm learning to deal with,it just blew my mind last night while laying down in dark messing with wallpapers and noticed all the uneven darkness on dark grey image,dark area's and faint vertical lines everywere.It appears it's from uneven distribution of glue.

I dislike the warm color on mines. Nothing is perfect, there's always something to disliked

Just wanted to toss in my 2 cents. I have had two Nexus 6 devices now, both with discoloration. Both are from ATT. The first device was darker to lighter, from left to right. Current device is darker on top, and lighter on the bottom. It is really frustrating because I love the size, and the screen is great in terms of resolution.
I am thinking about taking this one back as well and returning it. I have never had problems on my smaller devices. It bugs the crap out of me that I can tell the difference, mainly on lighter backgrounds. I don't think I can live with this phone for a year. Waiting on the M8 GPE to get lollipop might be a better solution for me.

Do you recall what the build date for both phones were? Not sure if it matters but couldn't hurt to collect that info.
I just called for RMA #2. Hoping it's at least not worse than the one I have now. I think I'm in agreement with you regarding just returning it and waiting until next year, but I already gave the Nexus 5 to my wife so I'd be downgrading the Nexus 4 she had before that...ouch.

Assuming the date under the sequence number on the box is manufacture date, this one looks like 11/17/14. I didn't think to check out the original device build date, but it shipped 11/18/14 from ATT online and I received it 11/20/14.
I have had my current one now for a day, Moto and ATT claim devices shipping currently shouldn't have screen issues, although my issue is different than the screen not turning on, or flickering.
I was so ready for a big phone, I am still within my 14 day return period, and I'm wondering if I should try this again to see if I can get a good one.

Hi All,
I'm coming in late but I just got my Nexus 6 from AT&T last night. I've been using an N5 since may and haven't had any issues. I noticed this morning when opening Hangouts, Chrome or any other page that displays white as the background that on the top it has a more greenish hue and towards the bottom right it has a purplish hue. I thought it was my eyes at first because it's subtle but when I'm paying 700.00 for a device it better have a perfect screen. So I played around with the adaptive brightness, rotated it etc. It didn't look any less green to purplish. The bottom right side of the phone in portrait (to the right or the charging port in portrait at any given appropriate angle) had a more purplish hue than the top left (opposing the camera). I'll probably be going back to at&t tonight .. which sucks because I JUST got it set up how I liked it. I hate rooting anymore which is why I buy GPE devices. I could have gone with any other device and rooted and may have to get back into that game if this is how crappy this display is going to be. Also I might add that the encryption does slow the device down a little bit compared to the N5.
P.S. Ignore my sig, I need to update that..

For mine (bought from tmo) the bottom is slightly darker than the top. I only noticed when looking hard for the "link" issue. Out of all the issues I could have had, I find this the least annoying of them.
Over all I'm happy.

I just got my Nexus 6 direct from Google (one of the lucky ones) and for the first time ever, a phone screen is really bugging me. There is a tint, darker from left to right. The most expensive Nexus I've ever bought (and I've bought them all) and the worst display. Very sad.
Here's some images, one with contrast as it was hard to photograph. Much more noticeable to the naked eye.
Does anyone NOT have this issue? If so I'd rather take the chance on replacing it.
Update: Returning it for a replacement. Google kindly gave me $10 credit for the troubles.

I received my replacement. The screen seems perfect. No gradient. There are definitely some defunct ones out there, beware. Mine is going back now. I hope you don't get it.

Screen Issue???

Ok. Is anyone facing screen issue on your P20 Pro? There seems to be a gradient colour shift which is very obvious in a dark room when the brightness is set to low. Plus it has a green hue to it. Have a look at the picture attached. Thank you.

I tried it for myself and with brightness turned down to zero on phone and in the app i can also see a very slight hue.
But to be honest, i am much more comfortable reading with some background light so i can at least distinguish something of my environment , and then this is a non issue.
For completeness i took a screenshot with my camera , and it's way worse then what i could see with the naked eye.
With the naked eye it is noticable , but not so bad as the camera makes to believe.
Anyway , a non issue for me.
And since my and your screenshot are suffering from the same hue shift , it might even be a problem with the moon+ reader.....

But to be honest, i am much more comfortable reading with some background light so i can at least distinguish something of my environment , and then this is a non issue.
For completeness i took a screenshot with my camera , and it's way worse then what i could see with the naked eye.
With the naked eye it is noticable , but not so bad as the camera makes to believe.
Anyway , a non issue for me.

Thank you very much for following up. It happens in the gallery too. I've tried it with different pictures that have solid colours such blue, red, green, grey, etc. Do you think the warranty covers intentionally? I bought the phone with full of excitement while I was in Singapore for a holiday. I love this phone so much but the screen is bothering me. Sigh!

I'm pretty sure its not covered , the screen works flawless under normal conditions even in the the dark. Only when i go to extreme's like setting negative brightness levels in software the problem really shows up.
I will never have this problem unless i actively go and look for it.

same for me. the vertical and horizontal lines are not really an issue for me, i though i can live with it: i had the same on my p9 plus but on the left, there is a 2cm zone on all the height really darker and it made it almost unreadable at night (lowest light), even with screen filter or not.
i returned my phone and now i must wait to order a new one... my provider tell me they will not have twilight anymore.
i'm very disapointed.

Amoled screens are always a lottery when it comes to uniformity. Sometimes you have luck other times not. There are good screens out there and this time around I got one of the better ones. I have seen others complain about screen issues so not all screens are good like with most phones that have Amoled. Below is mine at 0% brightness and the app you used.

Mine has the issue as well. I ll be getting my device replaced soon as it also has a slight gap between frame and back panel at top left edge

Same issue here. First P20 Pro had it from bottom to top (pinky purple at the bottom, yellowy green at the top), second one has it left to right, but more pronounced on the bottom of the screen.
Is it worth replacing it again? I'm not happy with paying a significant amount per month for this if the screen is bad on all of them.

I would like to check mine. What is the best way to check this?
Update: So i opened lcd test app on my p20 pro and here's how mine looked like in the dark.
I don't know if i did it right but tell me if i need todo anything more to check this propertly.

Oh ffs, my third one has it too. Significantly green in the top left running about half way down the phone.
I've now been to the store 3 times, it's a 96 mile round trip! Nearly 300 miles of fuel wasted on this rubbish.
I get "it's a chinese phone," but we're paying Samsung prices for it, these screen issues are just unacceptable!

Have p20 pro for 2 weeks now. Always thought it's some dark theme design before found this topic. Have top much brighter than bottom in low light conditions. Can't see in bright room or in dark room with brightness more than 50%. I wouldn't be worried if it wasn't so annoying while I watching YouTube before go to sleep. Half of the screen grey, another near to black.

99% oled screens has this issue. Some are less visible, some more. But every oled screen phone I held had this issue.
Now I have Note 9 and dark grays are uneven too.

I have a Note 9 now too and while it's not perfect it's one of the most even oled screens I've had when it comes to uniformity.
