Is this a sign that my screen will be going bad soon?

I have a Tilt 2, and just recently noticed that when the screen is off, a section of the screen has the "rainbow like warp color". Its not oil or grease, it wont wipe off so the problem must be in the screen, though it looks like its on the surface. However, I do not notice any degradation when the screen is on. Everything color wise and everything looks normal.

Should I be worried about this? Is this a sign that even though the phone is new, and its never been mis-handled, that the screen is going to have problems soon? I have insurance on the phone and not sure if I could even get it replaced at this point, or if id have to wait until the screen actually has issues when its on.

I have it too. But it doesn't interfere with my use of the device, so I don't really care...

No there all like that, I have gone through 2 and they both had more then 4 dead pixels as well. Find a dark black photo or just turn your camera on and put you finger over the lens and you will find many.

The Newton Rings are probably very prevalent. I can’t say that I agree with your statement on the dead pixels though. Sounds like you got unlucky with both devices. I’ve tested mine with 4 images for black, red, green, and blue. Every pixel works fine for me.

Its caused by the layers between the touch screen digitizer and the actual LCD screen. The soft flexible LCD materials touch and form Newton's Ring patterns that appear as the pictures show.
On my old phone (A kaiser) the original screen did not exhibit this behavior, but when I replaced the screen, the new one did...
Luck of the draw,and no it is nothing bad...

I had this problem in european tp2 model... took it for repair and they changed the screen in warranty...

HTC Desire - Dust spec! (Photo)

So I started noticing a pretty small dust spec on my new Desire, thought at first it might be a stuck pixel of sorts but on closer inspection (much closer!) it is definately some dust.
Below is two images shot of it through a microscope...

...would you replace your handset because of this? I've had it only one day, and you can see it with the naked eye if you know its there (albeit alot smaller! - about the size of a period/full stop)

You put your HTC Desire under a friggin microscope? My advice: Replace it if you really can't live with it, but you should realize that the dust spec is only about a 1/2 pixel in size...

If you are like me, replace.

Yes! The reason is that I wanted to check if it was indeed something above the screen or not. With the eye it looks to be a small square, right in the middle of the display. It is quite annoying to be honest, when the screen is one solid bright colour it is quite clearly there (like writing an sms), I constantly find myself trying to wipe it off like the other dust that gets attracted to it but it just stays!
I think I will get it replaced... it's just annoying that I've waited so long for it and now I have to send it back. Got to get the w910 back out the drawer! *sniff*

Have exactly the same problem, T-Mobile are going to do an exchange so no need to be without the phone. Just waiting for stock now.

what kind of camera did you take those photo with?
and this dust cannot be moved if you shaking the phone a little bit?

It's just a regular camera in macro mode looking through a microscope
saquib, good to know I'm not the only one! I got mine from vodadone, will ring them up tomorrow hopefully they will do the same did they agree to replace straight away? And are they sending a replacement or letting you pick another one up from the store? Thanks
Edit: no shaking does nothing its sealed below the screen. In fact under the microscope you can see that it actually sits in a teeny tiny air pocket

I have nothing on the phone yet I have a dust spec on the camera.
I'm not sure weather to take it back or not, it doesn't seem to effect photos.

lol I got a spec of dust but never see it unless I look.

[Q] What to do with DEAD pixels

Oh my god, I just noticed that my "new" (~ a month old) desire has a bunch of dead pixels . I counted 6 spots on the display wherer there is at least one dead pixel. One is clear to see, must be more than one pixel dead there. I can clearly tell that they are dead pixels, because if i tilt the phone they change color.
I tried PixelFix App but it did not help. (btw: having SLCD screen)
If nothing helps I will have to make use of the warranty. Will they repair/chang the display?
Anyone with the same problem / a solution? Or should i just go to my providers shop?
Should I remove the screen protector first? If they think I am stupid they might tell my its my own fault, because I am using the screen protector with glue (or whatever).

Well, dead pixels don't change color... remove the screen protector first and wipe the display with a clean, soft cloth the screen, see if they still show.
The warranty should cover this fault when a certain number of dead pixels is reached.
Otherwise, a whole new screen goes for around 130-140 $.

With monitors you need 2 dead pixells so I would say the same about screens.

First of all thanks for your quick replies.

On a black screen they clearly shine bright white or cyan (can't really tell because they are so tiny). If I change the view angle it changes to some kind of red.
Do such apps like PixelFixer help at all?

If I remember correctly, the colored stuck pixels that have other color than black are called sub-pixels and are the components of a "full-fledged" pixel, so a stuck sub-pixel could be your problem. In any case, neither should change color when tilting the screen.
I never heard of a single case of "healing" a dead pixel problem using a software, although in theory they all say could do it...
Did you remove the screen protector?

Just talk to HTC or your insurance or your carrier and see what they can do. Your still in warranty so best to take the safe route.

Dead Pixel(s)?

I have what seems to be a dead pixel that constantly seems to change color (when displaying darker colors it becomes visible) on the middle left side of the screen. I also seem to have one that flashes bright only once on top of the screen (not always, just when screen refreshes seem to occur).
Anyone else there having such problems with their X One? Sounds to be like a hardware problem..

a lot are experiencing the same mate, we don't know if its hardware or software no words from HTC so far
awaiting updates

Just found another (dead?) pixel. This one sits on the left side of the screen, and is only visible on grey or lighter backgrounds (not on black backgrounds). It is lighter than the rest when displaying a bight color, and sometimes flickery turns blue when swiping over colors on-screen.
Not all that disturbing, but I certainly don't like the idea of having a brand new phone with one (and potentially) two dead pixels on arrival.

Mine had 3 before I sent it back. Mine were dead, so stuck black.

Mine had a sticky pixel (the ones that can be seen over black background). It was visible only on very dark light conditions and over black background.
I wanted to go to the shop for replacement, but on that morning the pixel reactivated alone.
There are some apps on the play store that try to reactivate sticky pixel by changing the color of the screen very fast.
I doubt their effectivness, but they are worth a try.

I want to check One X for dead pixels in stock before I buy it.
How can I do LCD test at One X?
I try *#*#4636#*#* but I cant find LCD test here, so which code works for LCD test?

It is normally at the code you said, but seems to be missing on this handset. Use an Android app...there are quite a few.

But in stock Im unable to install any .app on it.
Any solutions how to check the display in stock?

Unless you have a very sensitive eye, I don't think you would be able to see a single dead pixel at the shop. The pixel density is so high that a single pixel is very very small. You need to watch very carefully to spot them.
Anyway, the best way to spot my sticky pixel was to take a picture covering the lens. You get a totally black picture, which you can view full screen and hunt for white/yellow/green/red pixels.
If the seller is veeeery patient you might be able to do that at the shop.
Maybe the same works for dead pixels, by taking a picture at a white wall.
What do the LCD experts think of this?
Anyway, all the apps on the play store for detecting dead/sticky pixel present the 3dots menu button. So they fail in detecting dead/sticky pixel in the bottom part of the screen.

Mine had a dead pixel along the top just right of the middle, I could only see it on dark colours. Took it back to o2 got a replacement there and then.

Attached a pic of the pixels I'm referring to. They are indeed 'stuck' pixels, not dead pixels. The one in the top only shows periodically. The other two are there constantly.
Also noticed the screen flickers on some apps. Now that I do find very annoying.
Requested a DOA return.
Mine was made in Taiwan.

i've been using the phone for a 3 days now, and i still have problem wit few pixels with exactly problem that is described in the first post. ota 1.28. did not help. did the pixel fix apps help, and if it did, how long have was the app active until the problem was resolved?

I am skeptical that running those apps will actually fix things. That was also why I returned that phone to be replaced. Got my new one today, and it has no dead pixels. It does however have a very vague yellow bar on the top of the screen. Almost not to be seen, only when the screen displays only white.
If it really is a problem, I'd contact my retailer and get it replaced.

[Q] Hot pixel?

Hi everyone!
All of a sudden my phone camera (Arc S) is showing a dead pixel (I guess), I don't know how it got there. It's just there in every photo now, especially in the ones taken in dark. I somehow suspect my bag, had put it in the cushioned laptop compartment and had lots of heavy books in the other compartments. But I'm not so sure... I've even tried reverting back from JB (Super Jelly Bean) to ICS, change roms and everything but it still says there... :/
What could I do about it? How do I fix it, it's really annoying! I use my phone to take the most photos....

That's really weird o.o I don't think it's the actual screen's problem (that's to do with pixels) because otherwise it wouldn't show up in screenshots as it's just a hardware issue. I'm thinking it's something to do with your camera. Does that white dot appear in the same position in every picture?

R: [Q] Hot pixel?
..dust?

Yes, that white dot appears in every other picture and the exact same position. :/ I guess it's got something to do with the cmos sensor.. I don't think it could be a dust speckle cause it's really tiny, I mean aren't these sensors suppose to be perfectly sealed? They aren't dslr where one changes the lens.

It's probably the camera. It's there a scratch on the lens or the lens cover or can you see anything else that might cause this?

I guess I'll take a trip to the service center in the coming days. There had been scratches on the lens for a long time already, but somehow it never ended up like this. (not that I cannot distinguish between new and old ones )
Thank you for your opinions..

Photoshop it from now on

Great idea! Haha clone stamp to the rescue!! xDD
