Dark line visible in lower brightness - Huawei P20 Pro Questions & Answers

If I use lower brightness, I can see a dark line in my screen... I have to live with it? What can I do?
I can't take a Pic of it, but I can notice it very easily... Top to all way down to screen. Width of a finger.

Never mind. I used LCD Burn-in Wiper app and the problem is solved!

[Q] Galaxy S Screen Problem

I am having a circle ring angle. Something like that.
http://forum.xda-developers.com/showthread.php?t=772528
I cannot see it in a totally black screen. And in a white screen.
It can only be spotted on darker colors like dark grey.
Also the "ring" is on the higher like the top of the wallpaper (not top of the screen) and its on the right side of the screen. When producing darker colors, the ring appear to be in brighter.
Note: I am using a anti glare screen protector.
Have you tried taking off your screen protector and see if the mark is still there?
I have a similar mark, it's just the screen protector.

Nexus One too bright

Is there a way to lower the brightness beyond the default minimal setting? I've noticed that even on the lowest setting, I can still use the thing like a flashlight.
Sent from my Nexus One using XDA App
Too bright? Haven't heard that one. Mainly complaints about not bright enough in the sunlight and such.
I'm no programmer or anything, but as far as I know the android system has a brightness value of 0-100%, and the user (or apps) can change the value to anywhere in between. There might be a hack to undervolt the screen, but as far as I know one doesn't exist.
I'm guessing he has an AMOLED... in which case, I understand. The screen is bloody bright, even on the lowest setting.
My only idea would be to install one of the CM roms that lets you use the surface flinger mod to change your display to a monochrome red.
download 'screen filter' or 'total screen control' from the market. they allow you to apply a dark layer dim your phones screen to however much you want. hope this helps
Only time I really notice mine is too bright is reading if I use white on black, so I use a grey on black.. Fixed.
Although yeah, if i poke into the market first thing in the morning or such, it's pretty bright.
Problem with the screen overlays with surface flinger and such is you have to manually enable/disable them. It would be nice if the screen would go lower in some cases.

Very faint horizontal lines on white background?

If you go into your settings menu, do you see very faint horizontal lines across the screen on the white background? They're very dim, but if you look closely with high brightness they're there on my phone. If you can, check yours and let me know if it's supposed to be like that.
Thanks.

Xperia SP vertical lines on screen

I noticed this while browsing the play store.. on light backgrounds or where the background is a single colour there is vertical greyish lines on the screen. They are spaced evenly with each line about 1/3 of the width of the space between them.
Someone posted a picture of it here which shows what I'm talking about

Is this how the screen is meant to be?

This is normal. With my XSP it's the same and I think this is caused by the display and all SP's should have that so don't worry
edit: What I mean with "this is caused by the display" is that I think that under the display is something, that has vertical stripes and because the screen is quite transparent you can see it in a special perspective

My phone has it too. I noticed it the first time I powered on the phone. I try very hard to ignore it everytime I see it
Good to know its normal.
I think it may be because of the glove mode feature, like some sensor under the screen that lets you use it without touch.

I don't think so. Before I had the SP i had the Xperia P without glove mode and it also had those stripes. Because it got broken I unscrewed it and the display as one had those stripes. Maybe just the touch sensors Whatever, for me it's not a problem ;D
few days ago I bought xperia sp. before buying looked at dozens reviews and non of them was pointing to this problem. I mean that there is visible vertical lines on bright backgrounds. I would never bought sp if knew that. how its possible that this phone is 12 by user rankings in gsmarena? are those users blind????

Rare screen effect

Hi, I wanted to ask if you guys, have the same effect on your screen. It happens to me only when I'm in low light situations, and it's like, the dark colors, like, mix together with the color that was before in the place that is now the dark color. Only happens when I move any dark/black content on my phone, fast, or not to very fast, but no slow. The best way to see this effect is on dark mode, and on the status bar. Take a reference the white part of your brightness slider. Then, you moove up and down your statusbar, and if you can see it, you'll see like, the dark part of the brightnes slider, shrinks when it's moving (taking as a mark the thickness of the white part of the brightness slider). At first, I thought that this was like a system effect (animation), but then, I saw it on a photo, the same effect, so I think that my screen is defective. I upload a video in slow motion for a better look, and to understand me. Also, I forget to say, but in the video you won't notice it, but, the part that shrinks on the brightness slider, it color, slightly changes to a blueish color.

haven't watched the video, but i think what you're describing is black smearing, it's an amoled thing becuase when black is onscreen pixels turn off

I don't quite understand what do you mean. But for my mi 9 lite, when the screen is all black and only has a few places of lighted up areas, those pixels seems to last a bit longer after it had brightened up.
Idk if that's just what AMOLED does.
This is normal for OLED screens, i have seen same effect on Samsung Galaxy S3 - S9, Nexus and OnePlus phones. Black = off pixels. When they turn from black to something else, they need to turn on. This causes a delay, which leads to the blurry purple affect. It can be slightly annoying but the colors, saturation and contrast outweight the con's IMO, i dont see myself coming back to IPS.
It also happens to me in the Mi 9 Lite. It seems to be some technology used on the screen.
