Thank you!

Danw, abusing a little bit of your patience, could tell me if this app is good to recover stuck pixels?

https://play.google.com/store/apps/...sMSwxLDEsImNvbS50aXBpZC5sY2RwaXhlbHRlc3RlciJd

This app uses the colors yellow, white, black, red, blue and green! Wide variety compared to other apps and the speed of flashing is absurd! I think I have a better chance of recovery with him than any other app!

If you can install on your device to check, please tell me if it's worth it!

Tks again!

Ah! Regarding macro photo, I will provide a camera to take pictures!

[Xperia Z Q&A, Help & Troubleshooting] alexp999:
I'm just about getting to the point where I will just be keeping my old HTC One X+ (I know it is not that old, but still).

I had 2 Xperia Zs around a month ago, first had dead pixels, second had stuck red pixels (wish I had known about fixing pixels with that one). As I was on contract the HTC One had become available, so I switched to that, hoping for a bit more luck.

I went through 4 HTC One Silvers, 2 as exchanges, 2 in store stock. All had dead (not stuck) pixels, so I managed to get my money back and decided to go down the retail route.

I got a Black HTC One from amazon, that turned up with a dead pixel, went back to the Xperia Z from amazon, that too had a dead pixel. I'm now waiting on a replacement, this will be my 4th Xperia Z, and 9th 1080p phone in the last 6 weeks.

I know I am probably more fussy than a lot of people, but most of these pixels I have noticed from having just turned the phone on, not even scouring the screen with a pixel finder app. I did try keeping one of the HTC Ones for a few days, but I just couldn't put up with it.

I have never seen this sort of issue with screens before. I know they are higher density, but I had the SGS3, LG O4X and OneX+ last year, all with 720p screens on launch and not one had a single dead pixel.
[Xperia Z Q&A, Help & Troubleshooting] BR4DOKYBrazil:
I had an Xperia S and he had no dead / stuck pixels!

I see lots of people having problems of dead / stuck pixels with device 1080p screen!

It's sad, but I'm learning to live with my stuck pixels!

The trick is to learn to focus on the thousands of qualities of the device and try to forget this one defect!
[Xperia Z Q&A, Help & Troubleshooting] danw_oz:
It is interesting, because of the pixel desity it would be almost impossible for a single dead pixel to be noticable with the human eye with normal use of the phone, it would really need to be a cluster of dead pixels to noticable. The fact you have had problems with almost every device you have owned recently is very interesting. Stuck pixels are a completely different story because depending on the colour would show up on contrasting other colours

White pixel is not a dead pixel
[Xperia Z Q&A, Help & Troubleshooting] alexp999:
Well 2nd Xperia Z arrived from Amazon today - 4th Xperia Z in total, 9th 1080p phone in total.

And.... It seems to look ok :D

I can't help but feel like the screen may be better than the first two I had 6-8 weeks ago. The screen looks stunning, like as good as (if not better than) HTC One stunning.

I think the biggest problem is genuinely the grey interface. If you dump the default wallpaper for one with some deep colours it really looks awesome. I reckon if the next update has black interface bars too, it will really show up that this is a really nice screen, just with a slightly dull initial interface.

Who is the manufacturer of the LCD screen (sharp, JDC)?
[Xperia Z Q&A, Help & Troubleshooting] alexp999:
On the bottom of the phone it says 13W13 AAC.

Haven't rooted phone yet so don't know about LCD unless there is a way of doing it without root now?

I've just collected a black Xperia Z from Asda Direct (UK) and it has one bright stuck pixel, it is going back tomorrow. This was the 3rd consecutive Xperia Z with stuck pixels, after the four HTC Ones with stuck pixels... :crying:

My Panasonic DMC-TZ10 camera can take surprisingly good photos of these stuck pixels, they may come in handy when explaining the problem in the bright shop where it is difficult to see them.
[Xperia Z Q&A, Help & Troubleshooting] BR4DOKYBrazil:
Upload these photos so we can see! If possible, take photos from several angles to see if the stuck pixels change color depending on the angle of view!

And here's some advice: Forget the stuck pixels! Screens with this high pixel density is virtually impossible to come no stuck / dead pixel! Who does not have it because it really did not pay attention!
[Xperia Z Q&A, Help & Troubleshooting] 9a6or:
See two photos below with stuck pixels on the Xperia Z.
[Xperia Z Q&A, Help & Troubleshooting] BR4DOKYBrazil:
It is exactly like mine! White dots! And depending on the angle I look, it changes color (red, green and blue)!

I learned to live with my stuck pixels! I was afraid to replace the device and the new one come with another problem (like vibration problem, yellow spot, etc)! So because I bought in another country, then the exchange is too complicated for me!
[Xperia Z Q&A, Help & Troubleshooting] cheetah2k:
Trust me apps wont free them. You need to get a replacement screen or new handset.

What screen do you have? JDC or Sharp?

I'm trying to find out the concensus which screen manufacturer is the worst for stuck/dead pixels
[Xperia Z Q&A, Help & Troubleshooting] droidhd:
I don't know what screen I had on first one, but on second XZ i have JDC and for last 2 weeks no dead pixels at all. Hope it will stay in that way :)
[Xperia Z Q&A, Help & Troubleshooting] 9a6or:
cheetah2K, I agree that apps cannot do wonders and nothing proves this more than the fact that I have returned my 7th phone today due to stuck pixels (4 HTC Ones and 3 Xperia Zs).

Does anybody have a direct email address to Sony at a high enough level? I'm prepared to write and ask them how I could purchase one of their phones with a 100% guaranteed screen.
[Xperia Z Q&A, Help & Troubleshooting] danw_oz:
You won't be able to, Sony do not make screens. They use other manufacturers who have tolerances of dead/stuck pixels, if you screen clearly displays worse than tolerances then you can replace, otherwise you just have to put up with it.

All display manufacturers have this, for all LCD/LED displays, TV's, Monitors, Laptops, Phones etc... and there are a few companies that specifically have 0 dead/stuck pixel warranties and you typically pay for that, but they are by in far the minority.
[Xperia Z Q&A, Help & Troubleshooting] 9a6or:
I've suffered from pixel troubles for many years, search for my posts. You are right, the model adopted by pcspecialist.co.uk is what I am after. They only assemble computers from components (with their respective tolerances) but they provide an option of dead/stuck pixel guarantee at £19 for a year. Before this I'm sure they used to wrestle with customers complaining about pixel problems on their expensive laptops. They could not change the LCD suppliers' sub-standard quality control so they had to suffer the loss due to returns. Then came the guarantee with its cost probably set to balance the equation or at least to reduce their loss. In return they also get happy customers who come back to them later.

Unless we keep pressing for such arrangements, suppliers will ignore us as the minority OCDs who have too good eyesight :)

If there was a mobile phone supplier who offered an optional £20 screen guarantee then I would buy one from them straight away and would go back to them. Sony could easily do this.
[Xperia Z Q&A, Help & Troubleshooting] Michealtbh:
I've been through 9 or 10 Android phones in the past 3 years and haven't once had a single dead pixel, have I just been incredibly lucky?
[Xperia Z Q&A, Help & Troubleshooting] 9a6or:
If you use your phone at night (e-book reading or watching films) then stuck pixels appear as static bright spots on dark backgrounds. They are quite easy to see because everything else moves on the screen.

To see them more clearly, adjust screen brightness to 100% and download an app to test dead/stuck pixels. Set the screen to black fullscreen and check in a dark room. Tilt the phone gently to see the very faint subpixels.

You have to have good close vision to see pixel problems (I am blessed and cursed at the same time), my wife can never see them (long sighted) buy my sons with good vision can see them straight away even in normally lit rooms.

The worst one I've ever seen was a Nokia N900, it looked like a starry sky. I think I counted 20 and then stopped.

Dead pixels are black dots on a white screen and less common these days.

Guys should I not buy xz.??. because I can get this issue....

What should I do?
[Xperia Z Q&A, Help & Troubleshooting] alexp999:
From my experience any 1080p phone you risk getting dead pixels.

For me the Xperia Z actually had better qc than the HTC One.
[Xperia Z Q&A, Help & Troubleshooting] Michealtbh:
Just tested and my XZ has one near the centre about 1/3 of the way up. Doesn't bother me at all though since it isn't visible on normal use
[Xperia Z Q&A, Help & Troubleshooting] BR4DOKYBrazil:
Exactly! The pixel density is too high! It is very rare there is a device with no stuck / dead pixel at this resolution, even with this density!

At first I was very angry and annoyed with my stuck pixels, but I'm learning to live with them! Faced with thousands of qualities of the device, the stuck pixels are minimal!
[Xperia Z Q&A, Help & Troubleshooting] amielxda:
I also have a bright stuck pixel.. I think i have 2.. on the upper right and lower right of my screen.. they are not visible in normal use.. they are only visbile if i set my brightness to maximum then uncheck the adapt to lightning conditions.. then use a black background.. I think this is a general problem so i did not manage to return my XZ in the store.. maybe I will have more dead or stuck pixels if I will replace it with another one.. Check the Adopt to lightning conditions in the display settings you will not see it.. :D btw my screen is great I think.. its a JDC panel

Finally i recieved an replacement after the first Z which had 2 stuck pixel. The replacement have only 1 stuck pixel but is barely noticeable with max brightness and with the automatic brightness off. When auto brightness is on with max brightness i cant fount it...so is ok.

In warranty it says that you will obtain an replacement only when you have 3 stuck/dead pixels so i specified that i have poor wifi signal , it gets very hot, and the video camera records with hissing sound.

[Xperia Z Q&A, Help & Troubleshooting] 9a6or:
I've just returned my fourth XZ, this time to Tesco Direct UK (again). It had the biggest bright pixel I've ever seen on an XZ, probably two next to each other. When the phone-shop guy checked it, he could easily see it even under the bright lights in the store. I mentioned in passing that there were another three faint stuck pixels but the big one was convincing enough.

I am now discussing the matter with Sony Customer Service in emails but I am only getting the standard responses so far which we know are ineffective (warranty repair or returning to the store).

I accept that some people are happy to use a brand new phone with a minor fault but I need one at 100%.

Boo, just found a stuck pixel on my screen.

I can live with it more than a dead pixel, it is a lot harder to see as I think it is only a subpixel (green). Plus it means the transistor is not dead, only stuck so may decide to work again in the future - I might give Pixel Curer ago overnight too.

It is a shame really with the modern 1080p phones, I'm willing to bet there may not be a single perfect screen out there, or the percentage is reveresed, so 99% have some sort of flaw.

Still no phone that comes up the production line is identical to the one next to it, everything it built to a tolerance, I just personally find screen tolerances the most difficult to live with.

[Xperia Z Q&A, Help & Troubleshooting] alexp999:
Overnight didn't help but am hopeful it may go in time.

I'm pretty sure it is only a subpixel and it has taken me 2 weeks to notice it. From the problems I have had with other screens it is liveable, though I might have to change my background to something less dark so I don't keep trying to find it :laugh:
[Xperia Z Q&A, Help & Troubleshooting] alexp999:
I had a quick look at my stuck pixel under a magnifying glass today and it is actually all 3 pixels. But they don't look white....

Depending on the angle you look at the screen depends whether you see the red, blue or green. Most of the time I see the green with the naked eye, but as I change the angle of the magnifying glass, I can clearly see all three colours.

I have had too many phones to replace this one again, plus a stuck pixel is easier for me to live with than a dead one.
[Xperia Z Q&A, Help & Troubleshooting] BR4DOKYBrazil:

[Xperia Z Q&A, Help & Troubleshooting] BR4DOKYBrazil:
Some cases solved with this app you mentioned, but for me and many people did not work! Yes there is a chance the stuck pixel fade with time, but it can take days, months, years. It's hard to say! A screen with high pixel density is impossible to come without dead / stuck pixel! Many people said the same problem occurs with the HTC One!

Attempts to leave the app running all night! Just take care of the burn-in effect, because the app does not work in full screen, leaving the navigation buttons on!

I've got three dead pixels, so annoying. What I noticed is one of them is smaller than the other two of the black dots. So maybe the bigger dots are two dead pixels combined. I don't know what i'm supposed to do. Does the warranty cover this or it is considered acceptable?

1 stuck pixel won't go away

I know this is an xperia z thread but I'd like to share my experience as well with xperia SP. I bought one from an authorized xperia store. 1st phone was white, spotted 3 stuck pixels (Blue).. I returned it and the store gladly offered a replacement. The saleslady actually opened up another white SP for me. I spotted 2.. We opened a couple more boxes and guess what, all of them have stuck pixels.. The last one, xperia Black, though has none.. I got the phone and after 3 weeks, well I spotted one tiny blue stuck pixel!!! Man, it drives me crazy. Although it isn't noticable in regular use. It only appears on a dark background with 80%+ brightness. But still, I bought it from an xperia store thinking that it would be a high quality phone and Sony gave me a stuck pixel. Darn sony.
