[Q] Are little dots on the screen normal while displaying a black image?

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.

Black Spots in S3 screen. Is it a problem?

Just bought a S3 weeks ago. I thought AMOLED display can go completely off when displaying just pure black . I tested it out with a full screen black picture. The display isn't going fully black it seemed like the display was ON with mild lighting. But the strange thing that I observed are some black spots(or random shapes) during this test. PLEASE REFER THE ATTACHED PICTURE TO GET A ROUGH IDEA OF WHAT I"M TRYING TO SAY. Is this showing something wrong about the display. What's your suggestion?
My suggestion is you search for the many other exact same posts before posting a new one, it's normal to see uneven black in low light.

New lg g2 out of the box faint white lines all over the screen, normal or not ???

I have a lg g2 out of the box faint white lines all over the screen, and i'm wondering is it normal or not ? I read a little today that there a 2 kind of screens out there. One screen is ok and the other has these white lines on it. I'm not sure if this is a defect or not. Some say these white faint lines are actually the digitizer visible on screen befause of the fabrication process. Other say that its kind of a defect and should return the product . My question is what is the truth ? is this a defect ? can it get even bad than faint lines in time ? or they will remain just faint lines ? Its not a deal breaker for me just yet , but if someone tells me that this will get bad bad I will return the phone . So please I need some imput
Do you mean those little Squares that make the screen look like a solar cell?
no , white vertical lines from top to buttom all over the screen , mostly visible on a white backround and open colours , they are all over the screen like a pattern , vertical , from top to buttom , very very faint , I can barely see them but they're there
nope,not normal. Faulty display. Send it to warranty. It will be replaced
Mhm. I do not have any of them... I would send it back for return... But maybe it's not bad at all.
Cause I read there a 2 types of panels lgd and jdi , one doesn't have these faint small barely visible vertical lines and the other does mand lg doesn't consider this a defect , that's why i'm so confused ), I've driven 2 a show center and played with one that's on display and I saw the lines also ...diffent store ) weird
Return, Now!
If u have a grid pattern that's normal. If u have two white lines u have a refurbished phone with wrong panel.
Have the same problem. Ordered the phone 2 weeks ago and since the beginning it has a small whitish smudge/spot on the left side of the notification area and 2 irregular parallel lines mid screen, under the first smudge. Visible most of all on a grey screen.
I didnt notice them at first, but in the right lighting at the right angle I can see white vertical lines.
As this is about .01% of the time, I'd say its normal. If you can see them more, send the phone back.
not normal for sure.I got mine replaced for the same problem..
