Pixel error - General Topics

Hi all,
does anyone now if a pixel error is a reason for an exchange under warranty?
I have one pixel that is permanent green. The Qtek is one week old.
This is very ****ty quality.
Does anyone know if I would get it exchanged?
regards,
Silver

Hi Silversurfer
Unfortunatly you will not be up for a replacment you can have a look at this link:
http://www.myxda.com/serviceandsupport/template/BlindDotsPolicy.vm
They are allowed up to 2 green dots with out replacment... It is not XDA's fault it is just a trait of LCD pannels. I have 1 red pixel that is rather anoying as well but thats one of the things you have to put up with LCD screens.
No matter what LCD screen is used there is always a chance of having dead pixels (Even computer screens) I have got 2 LCD screens at work that have a dead pixel each.... Nothing you can do really... just put up with it, its a chance you take for going with the LCD technology...
Sorry this is not the answer you where looking for... :?

with production of lcd it happens alot that some pixels are born dead
this is by no means a quality issue on htc's part
only extremely few lcd makers check and throw away panels with some dead pixels on if they did the prices of the panels would skyrise
read here about normal computer lcd panels and their warrenty rules
mind you they have tons of more pixels then the xda's panel and therefor have a much higher dead pixel ration

Yup... Even my laptop has a bright orange dead pixel on it.
I'm used to it now.

my super expensive samsung 19" panel have a white pixel in the upper middle
my xda2 have 1 white pixel and one stuck on green and one on orange
it cant really be avoided all together it comes with the technology

Screen Damage?

Hi, I received a new Fuze from AT&T two days ago and I have noticed a small, subtle, yellowish dot on the upper left hand corner of the screen. It is barely noticeable unless I am in an app with a white or grey background. I don't particularly mind this blemish, I am just wondering if any of you guys think it can/will worsen? Should i send it back to AT&T now? Should i wait and see if it gets worse at all? Or should I just leave it to luck and deal with it the way it is, it doesn't really effect the phones performance or display that much at all. All opinions welcome, thanks.
it's called a stuck / dead pixel
1 pixel == 3 sub pixels 1 red 1 green 1 blue as in rgb
each one can die in 2 ways
on stuck or off stuck
most lcd panels really got some pixel errors if one really check up on it
there are programs which can excise pixels and temp make stuck pixels work again but
sooner or later they get stuck again if one can live with it depend on how anal one is about noticing such things
It doesn't appear to be one pixel, it almost looks like its an image of the sun. Brighter in the middle and fades out at the edges, in the shape of a circle. I'd put it at about .25 inches in diameter. As long as it doesn't get worse I really don't care.
I have got 5 "suns" on my Touch PRO and one green pixel I can see it well on black picture.
Yes it is not so nice but phone is going well with it so i don't do anything with it
But when you have got a new phone, i will send it back
Hm, well as long as no one sees the problem getting worse I really don't mind at all.
I don't think it would be worth the hassle with AT&T over something so minuscule.

cracked my screen....

So year i dropped my phone in the bathroom and cracked the screen and now i can only see a tiny portion of the screen. Considering i also have the newton ring on my phone i think its time for a new lcd and digitizer. Would someone with experience in this area take a look at the following link and let me know if this is all i need for a replacement.
http://cgi.ebay.com/OEM-Replacement...wItemQQptZPDA_Accessories?hash=item41473b5370
You didnt say what phone you have!
If you have a Touch Pro then it looks right - i believe the fuze screen is slightly different (no front camera) so if you use this screen on the fuze you may see something through the camera lens.
I replaced mi display , it took me 2 hours to do it, but finally it worked fine. The only issue was the new display has a different color, the digitizer just worked perfect, even better than new, but the color is different, now the colors are less vivid and less brighter, I will try to adjust the display color settings, I will do it tonight.
oh wow good eye didnt even notice that. i guess ill go with this one i just found.

hey GussMiami, do you DIY your screen replacement?
I would like to replace my LCD by myself, but I do not know how to do it,,, tried to youtube it with 'replace touch pro lcd screen' or some thing like that but came up nothing.
tq before,,,
ps: if I have blue spots on my screen, is it some kind of dead pixels?
Xue v.2 there are a couple of guides around on replacing the screen http://www.att-phones.org/att-htc-fuze-user-manual.html
I ordered a new Digitizer and LCD for my Fuze yesterday as mine is somewhat scratched up, the job does not look particularly easy, at the moment I am debating finding someone else to do it for me vs possibly wrecking my phone doing it myself, from what I have read the hardest part is making sure not to break any cables/wires (commonly I see people breaking the speaker wires).
oh thank you naiku,
well, I think I will buy the lcd+digitizer for 30usd from ebay and have htc care to replace it for me,,,
plus I need to fix the keyboard as well. Let the pro doing the fix LoL

Check your screen for dead/stuck (sub)pixels.

Ok, so I am on my second One X now and both have had more than 1 dead/stuck pixel. You probably have some too and just haven't noticed it yet. The easiest way to check is to set the brightness to max then set the background to full black (you can get dead pixel testers from the market). You will see small bright spots. Look closely and maybe you might have to tilt the phone to slight angles to catch the sub pixels.
One phone I have has 13 bad pixels and the other has 3. Terrible QC.
My second replacement device had a handful of buggy pixels. They would flash on certain backgrounds. Got my third replacement, and it is perfect. I have no intention of painstakingly examining for ones I can't see. If I can't see them I don't want to know about them.
Rabble rabble rabble.
If i have to do all that to notice them then I am not worried about it.

The thing is you will eventually notice them and then by then it might be too late to exchange it. It's not like setting the screen to max brightness and a solid black background is something that will never happen on your device...
I have only one. I can only see it if i look for it hard though at an angle. Not enough for me to go out and replace risking a worse one. But kinda discouraging... Still in my 30 to decide if to keep in general

No no, it really is.
I have zero. I have ocd about dead pixles and have been checking every other day

I must have got lucky because my One X doesn't seem to have any dead or stuck pixels. I remember my PSP having multiple stuck pixels and that drove me crazy each time I used it because a couple were in the middle of the screen.
my first one had one dead pixel and back light bleed on the bottom, replaced it and my replacement is perfect.

No dead pixels here. Like davis, I had a stuck pixel on my PSP and it drove me nuts (replacement screen i got for 40$ from hong kong so nbd) Theres a tiny scratch in the glass of my Captivate which holds skin oil and refracts different colors like a CRT screen would do. That is by far much more annoying to me.
I got my phone yesterday and didnt notice it then, but now I see a dead pixel right smack in the center of the screen. It only shows on much lighter backgrounds, but my eyes keep gravitating to it. I might have to get it replaced. I hate that because I have my phone completely how I want it set up right now.

exactly what i was thinking
I found one that I can see ONLY when I use a screen test app on black background in the top right corner...going to exchange it. It's free to do so...so why the hell not?
Wow. This thread had me worried, as I've not closely examined my display yet.
I used a dead pixel tester from the market. Set brightness to 100%. The app cycled through several colors, including black and white.
I have 0 dead\stuck pixels. What a relief
No dead pixels for me either!

Dude, I remember buying the original psp on launch from my local bestbuy, bought the extended warranty they offered for up to 2 years and took my psp back to them after a 1.5 years and switched for a brand new one. My problem was 2 dead pixels on the bottom of the screen.
I've got one dead pixel. Either that or it's a piece of dust. Prolly dust since it's grey and doesn't really light up. Luckily it's in the top left corner and I have a grey widget there. You can't really see it.
*looks for it*
Actually... I can't find it today. It was there before, I swear.
Maybe it was actually dust....
Sent from my HTC One X
Checked the first day. Found none. Not going to be obsessively looking for one at this point. Had a little light bleed at the bottom, but i turned off the backlight on the capacitive buttons. I prefer it that way. Better reading/watching experience in dim environments.
Found one in the upper right corner. Impossible to notice unless I have a dark background present. Added with the fact that the screen is super high res its so small that I could care less.
I'm not going to risk receiving a phone with more problems for 1 dead pixel which I barely notice.

I'm on my 3rd (and final) One X but all three I've had haven't had any dead pixels.
Btw can someone post a picture of what the light bleed looks like? I'd like to know if mine has it but I don't know what to look for. Everything seems ok.

Yellow tinge in display

Hello friends,
Today only i have received my Tab2 7.0 and i am finding some yellowish tinge in display especially in White areas. Anyone else faced this problem ?
Thanks
remove the plastic screen protector, make sure it's not dead pixel (mostly dust inside the plastic screen protector)
if it's dead pixel then you should claim RMA warranty to samsung service center
Oh.....can this Plastic Screen Protector has so much effect
No as yet haven't noticed any dead pixels. Warranty i think is void because of flash counter

dead pixel doesn't means it's muse be black color, (if it's black without emitting light/RGB-color, then it's probably just a dust)
I've dead pixel in my laptop and the color is Reddish-Blue when displaying white scene on monitor.
The pixel contain 3 color (Red, Green, Blue), so in my case should be the Green-subpixel is died.
In your case (Yellowish tinge), probably because the Blue-subpixel is dead.
because Yellow color is produced by combining Red & Green color only (without Blue)
White color is produced by combining Red-Green-Blue subpixel all together, so you must test your screen under white scene (eg: in browser, white text editor, or program can detect dead pixel on the android market)
Oh man ! You got some in-depth knowledge about the subject.
Can you plz tell name of that app ?
Thanks once again !
I also have this yellowish tint display issue on my new tab 2 7.0. Most noticeable in white backgrounds, such as Settings or in Play store, or in the web browser. It's pretty yellowish. And overall the display looks washed out. I thought this is a PLS display..? Same as original galaxy tab 10.1? My original Gtab 10.1 has a much vibrant colors, and this one is really washed out and again, the yellowish tint on white backgrounds.
Is this normal? Is this not a PLS display? Do I have a defective device? Should I exchange it for another one (I prefer not to if it's definitely normal, but will def do if this is not normal).
Thanks for your help!
Could someone please answer to my post?
Anybody who has the tab 2 7.0 must have answer to my question if they also have yellowish tint or not..more technical answer would be also helpful.
Thanks.
Anyone???
I'm debating on exchanging it or not as I'm going to the place I bought it tomorrow. I already have everything set up on this device, so want to know if is is actually defective screen.
Some reviews say that the screen is vibrant, while some others say that it is washed out or yellowish. One review says they hear people complaining that the screen has yellow hue, but they don't have it on their device. I don't know who's right..I did search on this forum, and saw other people complaining too, but not much replies in any of the threads and one person said it must be the screen protector, but I don't have any screen protector on.....
Any help would be appreciated.

If you don't like it, return it. Or, at least you could look at another unit at the store and see if it's consistent.

That light bleed along the lower edge...

After trying and failing with the S8/S8+ I decided to go for the U11.
I ordered two phones from Amazon, one for myself and one for family. They were the amazing silver. We powered them on, and then noticed backlight bleed along the lower edge. The guy on this review is the only reviewer who mentions it and shows the problem:
http://www.androidpolice.com/2017/0...pretty-good-phone-if-anyones-still-listening/
Not only that, but both phones had a dead pixel on the screen (But I think that's just my bad luck . I took it on myself to watch reviews on youtube, and I think the lower edge problem has been there on every review unit, but no reviewer mentioned it.
I really am considering a switch to the U11, but I have a serious screen OCD so I wanted to put it to you guys... Do you all experience this? And is it terribly bad on every day performance?
Thanks

No shadow, no dead pixels (just went through a full pixel test - jeez this backlight will blind you on full!), no scuffed glass, nothing. It's the first device I've ever gotten from HTC with no complaints about the screen (my M7 had a yellow tint as did the M8 and the first few weeks of owning my 10, the glue hadn't settled so it was pink tinted and I had to have the Sprint store open up 8 EVOs before I found an acceptable screen to give you an idea - never had a dead pixel except on AMOLED ironically enough).
It's the Sapphire Blue.

Thanks mate I do love the phone, and am considering another go. My guess is you are -very- lucky, most of the units I've seen myself on youtube (if not all), have it to a certain extend. Treasure and keep it !

Yeah out of all phones I've ever ordered, this one is by far my favorite. Ridiculous battery life, no lag, great screen, no gimmicks (edge sense is actually quite useful - I use it to launch my camera immediately when I'm out and about), excellent camera, doesn't overheat, crystal clear call quality, loud speaker set up... Only thing I don't like is News Republic chewing up my battery and not being able to disable it.
I haven't even rooted it yet. Every other phone I've rooted within a week, oftentimes the day I've received it. I ordered it May 16th from HTC on pre-order and got it on June 9th. No phone has ever been in my possession that long without being modded somehow, even if it was just changing the launcher.
The light bleed problem affected every review unit as you said, and there have been several threads here mentioning it. My conclusion is that nearly every U11 has the problem although it's rather subtle so not easy not to notice if you don't know about it.
Personally I'm rather OCD about screens and I'm not happy about this defect but I'm now used to it. The location is just one that you don't look at normally. In fact I think we've grown used to ignore the lowest part of the screen as it's where ads normally sit. Also it kinda helps that the bleed gets reduced a lot depending on the angle you look at the screen from.

Thanks. I am considering getting a device regardless. I will ponder it over the weekend - and if you are OCD and can live with it, so must I. If you can help with advice on how to deal with such impulses (over screens), do drop me a message. I am desperately trying to drop that habit off.

I'm very OCD regarding LCD screen and the phone itself. The phone is perfect except for the light bleeding, a stuck pixel and some sound static in earphone. Otherwise the phone is perfect like the camera, sound, battery life and performance.
As I bought the phone from Hong Kong its a pain in the... To return it. So with a 10% discount off that seller gave me I learned to enjoy and love the phone.
My HTC One X, M8x, 10 U11 and the S8+ all suffered from flaws being the S8+ the worst (random restarting and pinkish screen tone) so I'm not a lucky person about phones.
@evak2979 i sent you a message but basically it's about accepting defeat when it comes to small flaws, unfortunately there's not more to it. Although of course, if your phone has serious build issues that no one else has it should go back to HTC.
I have is as well. Actually this is my second unit (Black), the previous (Silver) had it as well. I can see it in display test application but I would say it is not affecting normal usage. Overall I am happy with display quality.

Like I told my new pal on PM, I got the S8+ new for a very good price (539, UK).
If that sinks, I'll bite the bullet and return to HTC. It's funny because I don't mind scuffs, or scratches, or what. I just want a normal okay screen. I remember being happy with Note 4, with S5, With M8, With M9.
Then this new fashion started with every display being the dumbs
And the S8+ arrived with dust under the glass.
I've fought for a long time with my OCD to accept that AMOLEDs will never have consistent whites (though my one plus 3t is perfect, the one phone I've kept over the months). As of late with the S8 it's also been, full red edges, dead pixels, dust specs.
Let's try the U11 again. If it just has light bleed and no dead pixels I'll keep it...
I don't have light bleed.
I use edge to launch my calendar.
Sound through the earphones is shockingly good!
It looks dated in any other color but blue or red.
Those bezels? Ug.
The screen is beautiful and they've coated with oleophilics that feel INCREDIBLE.
The camera is excellent.
It's a very VERY good phone.
I have it on mine, but It's hardly even noticeable... Definitely not a game-changer for me. It's not enough for me to return it for a new one.
Just updating that I received my HTC U11 black, and I sent it back with a dead pixel. That's the third U11 with dead pixels, the first two having been silvers from Amazon.
I have also encountered issues with S8s (dust under glass), but not so much or frequent.
I want to get a U11 more than I do an S8, but I am really really skeptical about a few things - the build quality of the panel. The reports that some of the units are not so water proof (The solar reds apparently, a youtube search I did testified to that.
Sorry for diverting this thread from its original post, but I am really curious about you guys' opinion. I agree to having screen OCD, and that I should lower my standards when it comes to white consistency on AMOLED, for example. Or even some light bleed on LCD panels.
But dead pixels? Dead pixels on 649 pound devices, top end flagship? What is going on with QC and how lost must we drop our standards.
And if anyone thinks I am lying I am happy to provide with pictures...
If anyone from the UK has a relatively faultless HTC, please tell me where you bought it from so I can buy from there myself. And which color variant.
Thank you.
Hi, I believe you as I have the same problem with my Asian version. But can you share a picture? I want to compare mine with yours.

Of course...Here. Same on all three, just in different positions.
Mine is in a similar position but it's not black. Indeed it changes according to the color but of course it's different from the rest. Mine is more a defective pixel than a dead or stuck one. I thought it was the same pixel issue but it's not.

Nah mine is dead dead.
I am considering a 4th U11. At this point, I don't even care about the light bleed. But 3/3 with dead pixels, it can't just be bad luck. That's the thing. I mean this is very bad QC. None of the reviewers are mentioning things like this. Or the issues with the S8 screen.
I think at this point someone needs to step up and say : ok guys, these are the GOOD things about the phone. But there is also
S8 (red tints, even after patch. Bad smudges on grey. Dust particles under panel)
U11 (Dead pixels. Light bleed at bottom of the screen).
In the end, the only trustworthy review is XDA forums and its users.
