[Q] Are little dots on the screen normal while displaying a black image? - Xperia Z2 Q&A, Help & Troubleshooting

I just got a new Z2, I noticed there's a visible array of little dots on the screen (or glass) when the screen is off or displaying a black image under artificial cold white light.
Is this normal on the device or should I get an exchange?
It's my first IPS display, I come from an AMOLED world.

I think that you see something like this if am not wrong. And if you see this, i will just tell you its normal.
This thing is called digitizer grid, on some phone are more visible, on some phone are well hiden, anyway, any phone out on the world have this.

Possible pixel problem on second Hero phone, help ;(

Yesterday i bought a HTC Hero (my first one). When i turned it on and toke a good look at the starting screen (the one that says Hero, and HTC), i found a white pixel, probably dead or something. I went back to the store to get a new phone. This was not a problem at all and i got a new Hero. Now again, when i turned on the phone and toke a good look at the black screen, i also found 2 pixels with a other wierd problem:
The pixels also turned out white when i looked at them in a specifica angle. Just to be clear, i am watching on a black screen (starting screen). If you look at the screen and not in a specific angle i cant spot the pixels directly, but when i tilt over the phone slightly they show up and are 2 little white dots.
After i found out i downloaded the Detect Dead Pixel app. This app can create a black screen, the same screen as the home screen. When i use this app to spot the pixels again they are way less visible than on the home screen... I can spot 1 of them a little bit if i look at the screen in a certain angle and i can see a little dot, but i cant see them that good as on the home screen. They are not visible on other colors, only black.
I really dont know what to do with the phone now ... does anyone know what this is? im a bit concerned. Thanks!
After a bit more research on my phone i firugred that the dots really arent that visible. Maybe its just dust under the screen? When i put on a black screen using some kind of Android app i can not spot them. If the pixel is lazy or dead it should be clearly visible on a black screen right? for the lazy one then.
Anyway, i spotted a other problem on a black screen:
A brighter spot on the top part of the screen (like someone is pressing on it a little bit). Is this a problem ? im deciding if i should return the phone again..
Well its entirely upto you mate - i dont know what contract you've taken out but you may have that phone for 2 years. If your not entirely happy with it i'd take it back while you still can.
Issues with the screens rarely correct themselves.
My first Hero had around 10 dead pixels and i got it replaced as i wasn't happy with it. I now have one with a perfect screen and i'm really happy with it!
Well i just returned to the store and got another phone. This is the 3th one, and it still has problems, even more then the previous ones ....
On the boot screen there are about 10 very very tiny white wierd points visible ... im getting a bit frustrated here. What is this with all the screen problems ? :S
looks like they got a bad batch in your shop... have you considered powering up the phone while you are still in the store? might save you same time and way...

I have done that, but as i said, its only really visible in a dark room with screen brightness on 100%. I have checked the phone in the store and it just wasnt visible. When i checked the screen in a complete dark room i spotted the little things again. Looks more like dust to me =\
If your brightness is 100% you should see that one single pixel immediately.
Try making an image in paint (480*320) with a black background and a single white pixel. Open that image on your phone. The dead/lazy pixel should be just as bright as the one you drew.
Also the brighter spot is normal. It's called "backlight bleeding". Every lcd screen has this 'problem'.
They are not clearly visible, i think they are smaller then pixels, but they are countable on the bootup screen. When i tilt the screen them seem to change color (might just be dust). Green etc. I dont know what to think of it, come on. A wrong batch shouldn't be the problem if its dust, then its just a assamblation error. But 3 in a row?
I'm getting a bit pissed
It's dust or a fingerprint blocking a very small subpixel. Can't you just wipe it off? But I suspect very tiny scratches.
idk whether this is possible, but it might be dead subpixels. that would explain why they are smaller than a full pixel...
Does anyone know if that is possible? it sounds like a good explaination. Dead sub pixels could be the problem. They are smaller then pixels, but beg enough to be counted (i can count over 13). Little white dots on a 100% brightness black screen.
It must be dust, its a common question among hero owners. Most of the time the things they see is dust. It would be crazy if all new hero's have up to 10 or 13 dead pixels.
Ok well, here's what happened next:
I returned my phone again, god my cash back, bought a new one at a other store, SAME problem. Swapped it for a new one again, same problem!
Got my money back and i completely changed my mind of buying a Hero.
It is not dust. Its a perfect white dot, and definately some kind of pixel issue.
To bad..
Are you sure you're not being pixel-paranoid?
When reading all of this it sounds mostly like small dust particles under the screen. And looking at the number of phones you have tried, chances are you also got one with a real dead pixel (hot pixel, always on).
But I also think you are obsessed about it. My phone also have one dust thingy somewhere which I found just like you did (pixel tester, black screen). Smaller than pixel and less bright though.
I never notice the thing under normal use, unless I really go searching for it with a black background.
So you might make it bigger than it really is and miss out on a really nice phone.
Then again, we all have our own quality standards and its good yours is a high one!
I have had a tiny dead pizel since I bought my phone. Only really see it on the bootscreen.
I was always more bother by the light you can see coming from under the keys at the bottom and near where the lcd meets the keys.
I also have 3 dead pixels but they aren't that irritating.
I also discovered them when booting up the phone, but for me, they are sea blue (all three)
Maybe it is 2nd hand stuff HTC uses on their phones?
i have about 7 or 8 dead pixels too. it doesn't bother me too much anymore... only notice it in a completly dark room on the boot up screen... probably a common problem with the lcd screen the hero uses
All Hero's have this, or will have it inevitably:
The screen does not connect fully; there is a rubber-border between the glass and the metal frame surrounding the screen.
Look from the right angle, and you can see that there is a small 1/10th mm opening. Dust will come through here, and it will get on the screen.
HTC will wipe it off free of charge of course.
It is NOT a dead pixel; these can be seen from any angle, although the color changes a little but because of the viewing angle.
Call HTC and say you have dust under your screen, they will fix it for you, free of charge.

Screen defect

Hello to all
As the title says it's another screen defect that this phone have
I have noticed a darker area, which make almost a perfect rectangular shape upper to left of the screen and it is visible only in some circumstances
- screen brightness need to be lower that maximum (the lower it is the higher this defect is visible)
- mostly visible on grey image (for example the market startup) see other images in the links

http://imageshack.us/photo/my-images/864/img0633u.jpg/
not visible at all on black screen of course but when the screen is off and with a bright light (sunlight of a power lamp) in some right angles I can see some darker dots (looks to be some kind of liquid inside the screen) at the size of 5mm and also this rectangular shape (good eyes need here ) no picture for this because it is not visible with any camera
I wonder how came to this and is any possibilities to fix this such as those screen burners, could these help? or only a screen replacement?
PS: phone have no waranty
Thanks
Screen burns are permanent on AMOLED as far as I know. You'll either have to live with that or do a costly screen replacement.
Ah well, guess I have to live with it, not a major problem but it's looks a bit ugly sometimes.
Just read a bit more about amoled screen burn and it seems that the blue leds are the most that probably get weaker in time and causing this screen burn, and yes this is an explanation why on a blue screen this is almost not visible no mather of the screen brightness
Maybe burn all the screen with a white image, but I believe the result can be worst that this
Thanks

Blue Vertical Lines In Sunlight

Hey guys. Was out and about the other day and was using my phone and as I tilted the phone down out of the glare of the sun I noticed some weird vertical lines on my screen. Each evenly spaced same colour etc.
I can not replicate the effect unless there is large amounts of light or im outside in real light. BEAR IN MIND ITS ONLY VISIBLE AT CERTAIN ANGLES.
The lines don't appear on any pictures or hinder the video. They ar only visible during sunlight.
What im wondering has anybody else got this I will say issue. Or any insight as to what it could be? If there's a problem Carphone warehouse will want to repair it and not give me a swap for a new phone. What light does anyone have to share. Or am I just being paranoid?
My Titan is exactly the same, I think its just the way the screen works and is nothing to worry about.

I've got mine from Carphone warehouse. Haven't noticed this yet. They will replace it for you within 28 days. Else it goes to HTC for repairs. However, where did you find this sunlight? It's been so gloomy out here. BTW as mentioned above, this could be just the normal screen behaviour. The other two issues with screen that have come up so far are - the pink dot in the middle and grey keys visible on white background. Nothing back from HTC.
Hold your Titan with the screen directly facing you, at about 3/4 arms' length (as in, just sorta normally with your elbow bent a little) under diffuse light, with the phone powered up and the screen off.
Then tilt the phone backwards. As you get about 3/4 of the way back, you might see a regular pattern of thin stripes running up and and down on the screen.
They are not visible when the screen is powered up. I think it's just a normal part of the way the LCD panel works. As an analog, on my Dell Venue Pro, I could see a grid of dots under its AMOLED screen when looking closely at an oblique angle similar to as described above.
I also have a matte finish screen protector on my Titan, which might be making this more pronounced. In any case, it is absolutely *not* happening when the screen is powered up -- even in black areas of the screen.
Hmmm... Maybe it's a future charging grid.
have you guys noticed anything new in regard to htc amaze blue lines. i just go the phone a week ago and i have been noticying the same things. any new info thank.
My Titan also has these blue vertical lines, and it is seen only in daylight with screen off.
I see the same too but I thought it was from my screen protector...

[Q] Bluish burn-in on my screen

Hello, I own a i9100 and I have some burn-ins at the top of the screen that replicate some buttons of a browser or something, and some burn-ins at the bottom as well. I have read that leaving overnight an app that's constantly switching colours, with full brightness, could help a bit on that. I also read that leaving a blank screen (white image) on the same conditions (overnight, full brightness) would help as well. My question is, how true these both things are? I don't want to end with a bigger problem than the one I currently have. The burn-ins are most viewable at Blue, Red, and Black screen colors.(like if I put a background with one of those colors on it)
Never had any of these on my S2,but from my experience with the galaxy s plus,these tricks won't work.None will to be honest.It's permanent.This shows how immature amoled technology is.Learn to live with it or replace the screen if that bothers you much.
what a sign you got there...
Lucky you. Mine is not THAT noticeable if you're using it normally, but as soon as you open something with a plain color on it, the burn in shows itself on all its glory. So right now you can't tell if leaving the white image all the night or the thing switching colors will damage my screen more?
mwehehe
Well,back then when I tried every method you described above on my i9001,I didn't noticed any improvement nor any further damage.Even after running those for 10h+.So I assume it's safe.Can't say the same for the S2 though,have no problems with it.

White spots on display

I received my X F5121 two days ago, and as soon as I turned it on, I could notice a white horizontal spot a bit up from the centre of the display. You can notice it more when on a white blank page and with brightness a bit up.
I also found (more on white pages) that pushing the back cover of the phone would affect the screen with distorted colors and looks like (in my opinion) the glass is not properly installed on the device.
Am I the only one with this problems?
Let me know what you think...

I know, in facts looking at this image with brightness set at 50%, with my X bent of 160/180 degrees I can see that white spot

Is it like a white patch whether its a white screen, or a light color like beige background, like something is being pushed against a lcd screen, or a light bleed.
I had something like that, not sure if it was when I purchased the phone, but I only noticed it after a few months of using it, I took it a xperia service center and had the whole screen, including the phones outer frame body changed, not sure if the center was too lazy to change just the screen, but im happy with it now.
You should get sony to sort it out, or if you still have a return period for exchange/refund.
