My XDA Stellar has just arrived and it has what appears to be a dead pixel a quarter of the way up the screen about 5mm in from the left hand edge. It's it is lit in blue on a black backround but is white on a white background.
Do I have grounds for a swap or will O2 say it's unavoidable etc?
I returned my tilt to ATT because of a dead pixel without a problem (within the first 30 days.) It was bright WM6 green and it drove me crazy
kaiser
i have a kaiser with a dead pixel not happy about it. been trying to fix it with software with no luck. im very dissappointed with it and htc wont replace the phone with only one dead pixel.
I had a dead/stuck pixel, all I did was massage the screen a bit , apply a little pressure and move your finger up and down over the dead pixel , should sort it out. As per company policy I think 3 dead pixels are required to get a replacemnt. After the massage(which was 20 days ago) the phone is fine without any sign of the dead pixel
Dead pixel
I'm sure this will not solve everyone's problem but it might help a few. I had a pixel that appeared to be always on. It showed blue when the background was black. I powered off my TyTn II several times and the problem was still there. Then I tried pulling the battery and "Bob's your Uncle" the problem went away. I have had this problem twice and each time the battery removal has solved the problem.
Hope this helpful to some of you
Ok I've tried using magic fingers on it and pulling out the battery but it's still there.
Think I will call Customer Services tomorrow and see what can be done. Ideally a swap out at my nearest store as it's a pain in the arse to do returns.
Quite annoying really as I'm dying to H-SPL and get a proper ROM on it, but whilst I'm undecided about what to do with it, don't think it is too wise.
how can i see if i have a dead pixel or not?

If you haven't noticed it you haven't got one/any!
The pixel doesn't work i.e. it doesn't show the colour it is supposed to. Mine for example is permanently blue, so isn't noticeable on a blue background or a white one (white because red and green are also on to make white), but is noticeable on a black or green background and I would presume a red one too.
Guys, don't forget about my article in the Wiki, which can also help:

Thanks I cycled it for 10 minutes and hasn't fixed it. I'll run it overnight and see if it works, but in any case O2 are doing a swap out on Tuesday.
I wouldn't be satisfied with a dead pixel either. Massaging shouldn't work in this case because the touch sensitive area should not touch the LCD.
I have one dead pixel on my TyTN II. When I called HTC Finland they said I need to have about six!!! to get it repaired under warranty.
I didn't check for dead pixels when I receiced the device (discovered the dead pixel later that same night) and didn't have time to deal with the issue, so weeks passed by.
My dead pixel is WM green and only visible during boot up.
from what i have gathered, the dead pixel problems occure a lot on the kaiser, the screen used are very cheap, that why ppl have noticed, that the kaiser has two different type of screen.
my first tytn 2 had a red dot on the black screen when you open the phone, during normal use, nothing shows up, i had it changed when i found out, and i spent about 1 hour checking through the new unit.
I have two program for checking dead and stuck pixels, one of them actually fixes the pixel problem, but as pointed out 50/50 chance.
let me know if anyone needs the program, and prepare to let it run fir a few hours.

My answer to the original question:
NO!
On a device with a very low resolution screen such as the kaiser, a single dead pixel is not acceptable. Manufacturers who make LCD displays with millions of pixels typically have limits of 3-5 dead pixels, but this device has only a few hundred thousand, which makes a single pixel stand out like a sore thumb.
HTC should be ashamed that they can not support their devices. If my tilt had a dead pixel, i'd have taken it back to AT&T immediately. Contact your vendor and demand a replacement. If you've purchased it recently enough, and they refuse to take it back, send it back to them via certified and signature confirmation mail (tell them it's coming), and after it has been received, call your credit card company and revoke payment from the vendor.
Remember, unless the vendor had a highly visible disclaimer about dead pixels, if you received the unit with dead pixels it is defective and NOT what you paid for.

I'd love a link to the programs you used.
How can I tell if my phone has a dead pixel or a stuck pixel? It is just one small white spec and it's annoying the hell out of me.
HTC has a serious quality control issue with it's new Kaiser. This is my 4th and I will exchange it again if I have to. It's just sad that I actually miss my 8525.. I might even give up and buy another 8525. It was a solid device imo.
Check this out if you DID NOT get the stuck pixels go away with the links posted above! The video really can help, and the other mentioned methods.
They didnt work for me, so here is my way out. I got my screen repaired UNDER WARRANTY!
I heard awful stories how HTC refused to swap devices/screens under warranty, because of dead/stuck pixels, if there isn't like 4-6 there.
But still, at least I got my Kaiser repaired under warranty, just by calling HTC official support. Got a statement there that my provider should fix it, then took down the reference number from HTC case and called my provider, and they agreed to swap it! (gave the reference number, and told that the screen is supposed to be swapped!) I am so happy right now! *Knocking the wood*. Hope I'll really get it back after 2 weeks with no stuck pixels on it anymore.
Of course I needed to tell them at HTC that I think itäs totally unacceptable to have 1 stuck pixel on the screen. As in comparison to 19 inches screen that equals to 15 stuck pixels! Don't know if that affected the decision, or maybe the customer support technician was one of the nice kind.
I just got my tilt two weeks ago and one friggin pixel went blue on me right in the middle. i was about to return the phone but "massaging the screen" trick worked.
im pretty disappointed with the quality of the screen.
Dead pixel came...dead pixel went
i've been using my store bought tytn 2 since may 2008 and i encountered a deal pixel today...
it was blue on black background and white on white background...near the today screen clock's last digit in portrait mode...
i kept my cool...the idea of massaging came to mind so i did a couple of finger swipes over the pixel...10 seconds into the problem but the dead pixel was still there...now i panicked a bit...but then i flicked the side of the phone near the power button and viola...the dead pixel is now alive...hope it doesn't recur...(fingers crossed)
maybe "flick from the side method" is worth mentioning in the wiki for other people experiencing dead pixels...?
Anyone can help please, i don't know it's dead / stuck pixels on my screen (refer attachment). On the area of defection, sometime it will become small area and sometime it will grow to bigger area. On the screenshot, i'm running the "jscreenfix", but after almost 2 hours running, it remain the same with no changes. Please suggest any other method to fix other than replace a new screen since my topaz was already over the warranty period.
No one have solutions?
You can try to run a hard reset and see if its software related.
I made a topic end january about a stuck pixel i had(can't find post now). I wasn't able to resolve it manually and wanted to send it back. I was too lazy to do it but i just noticed it's completely gone. Someone told me that they don't disappear automatically. . I'm very amateur related to screens so i just believed him. Guess i shouldn't
Yeah sometimes dead pixels can get unstuck. There are a couple apps in the market which will flash different colors and moving patterns on the screen to try and fix it. Won't always work though. Wouldn't be the first time I've heard of one getting unstuck.
The answer is yes but unlikely and even less likely to stay that way. A dead pixel is due to a manufacturing defect or damage. If something about that defect has changed the operation can change. But its likely it won't last forever.

Read this http://en.wikipedia.org/wiki/Defective_pixel, very informative.
my HTC One had a stuck pixel and it was green
After a couple hours of netflix it went away I guess there was too many activity on the screen and it forced the pixel to get unstuck
It wasn't a dead pixel. A dead pixel is black and stays that way. A stuck pixel is either blue green or red(on RGB) because 1 of the subpixels is always on and stays that way. A dead pixel is when the subpixels won't turn on anymore at all.
Woooh i 've learned alot because of XDA
But yeah i'm very happy and surely be looking for it if it comes back, i'll let you know if it really stay that way.(The pixel was only noticeable when watching a movie with really dark environments)
Edit: oh and i also know what a hot pixel is now: It's when all the sub pixels always stay on and is completely white. This because the transistors are blocked off which lets all light pass through it.
Hello all!
So, I've been in love with all Xiaomi Products for a long time, my my phone is an OnePlus One and I can say that I'm not a newbie regarding this Android world.
Months ago I bought a Mi Pad 2 which had a strange behaviour with the screen, sometimes when I lock the screen, I couldn't unlock it. After spend an afternoon, flashing, reflashing and trying with different roms, I could fix it.
Yesterday I got my Mi5, It came perfectly on its box. After charging for a while (It came without charge) I tried to set it up. It came with Miui 7 International version, play store and play services already installed.
I notice a strange behaviour with the screen out of the box, it didn't respond very well and sometimes I couldn't unlock the screen. So I decide to Flash Miui 8 by following the Miui.com instructions but nothing changed, I'd said that I got worse.
Looks like the screen did not respond very well, after using a "touch screen test" app, I could see that the response was very poor, I barely could detect my 2 fingers and if I try to draw a line, I doesn't recognize all the movement that I'm doing in the screen.
Have you guys seems this before? Do you think it's a soft issue? For me it looks like a hardware issue, I already open a ticket with the support, but would be amazing if I could fix it by myself.
Btw, meantime I request to unlock my phone from mi.com/unlock but I don't want to touch the bootloader till I don't get an answer from support.
Thaaaaaank you!
Normally mi 5 doesnt have that issue, even i never heard that was a bug. So i guess it hardware issue, return it to your dealer

mi5 touchscreen problem
I have the same problem with the MI5 32GB i have buy it at December and from the start has some issues with the touchscreen but i try like you to change the ROM but the problem stay ...... so i don't know what need to do if its a software problem, but may this is a hardware and need to speak with the store i buy this device....
IF YOU HAVE FIND A SOLUTION PLEASE ANSWER ME
Thanks
Recently I replaced* my oneplus 3t screen as it was broken.
When asked in official service centres, the price was not affordable tbh as I could buy a new phone in it.
That is approx. 170+ USD.
So I went for a duplicate copy display.
The thing is I bricked my smartphone before, so I used the unbricking guide and installed everything from the MSM tool.
I am not sure whether the flickering is due to the display used, some problem in the digitizer or I have made some mistake in installing and its due to a software fault.
Please help me to find out whats the problem, if its the screen issue, I'll have to be accustomed with it and if not and there's some software fix, it would be great.
P.S: A noob here, sorry if this thread seems too lame but I required assistance.
If factory reset doesn't help, then it's a fault either in the new replacement screen or on the logic board of the phone. You didn't buy the cheapest replacement screen did you? These are usually second or third hand sorting with some quality flaws.

Hey, I'm running into the same problem. I had my screen replaced and the screen would flicker as it turned on. The repair guy tried a bunch of different panels but no luck, the issue persisted. Did you figure out what's causing the screen to flicker? Is it a software issue or a hardware one?
same here, i don think that it's software because it's flickering (in my op3t) even in TWRP when screen have more to refresh like it's changing the background. now i'll backup phone then Factory reset, can someone tell me how to check what type of screen is mounted? aida64 doesnt tell me anything or i just cant find
Edit:
As expected nothing changed but it's on my Op3t YOURS can be different
