Spots on screen when looking at something black - Galaxy S II Q&A, Help & Troubleshooting

I've been using my phone in a dark room without lights for some evenings, and I noticed, that when a total black image is givin, like the YouTube app loading a video some weird darker/lighter spots are visible, this is also visible when displaying a black image.
I'll try to make a picture as soon as possible, but does anybody know what it could be? Its like someone pressed the screen really hard, but nobody ever did.
The spots are not visible at any other image, only on black image.

I have similar problem with my Xperia Z. When the screen gets completely black on max brightness I see a small dark gray spot...
So I can say it's screen issue due much hard presses on the screen
TapaTalked from my Xperia™ Z (C660²) running Dirty Unicorns ROM!

Same here its most probably due to some bigger push you didnt notice or overheating or even it could be manufacturer line issue unfortunately :/

[Q] Banding on black background in stock lockscreen

The title says it. I made a completely black picture on my PC, and use it as the background for the stock lockscreen. Despite this, there's a brownish horzontal banding across the bottom of the screen that fades upwards across a third of the screen, when it should be black! I thought this was a screen deficiency at first, but then i saw that this banding isn't there when i display black images in the gallery or anywhere else except for the lock screen.
Build GINGERBREAD.XWKE1 stock ROM, rooted, Kernel XWKE2.
1. Does everyone else have this?
2. Does it go away with an alternative lockscreen?
3. Are there usually this many bugs on new Android-devices, as there evidently are on the SGS2?

I changed to a black blackground too a while ago.
As I found out it is actually better for your battary to have a black background.

it's a problem with the screen.
It's called 'screen burning or image ghosting'
When a static image is displayed on a screen for too long, the image will become a ghost and will show on the screen, no matter what you are viewing.
It's more common in oled screens than LCD.
Since you said you just bought it, I'll advise you to return it.

[Q] Lock Screen not taking advantage of super amoled

Hey guys, I got my phone last Saturday and have been playing around with it ever since.
I noticed that I had the night clock bug (whole screen is lit up) and as far as I know it's already a confirmed software bug. What I also noticed though was that my lock screen is also lit up. I'm using a pure black wallpaper which works well when the phone is unlocked (appears pure black) but the black is lit up when the lock screen is shown. It's almost like there's backlight bleeding. In the home screen and lock screen preview though it shows that it should be pure black
Here are screenshots of the "bug". I'm actually thinking it's a software bug since it was captured by the screenshot. http://imgur.com/a/p5maP (Take note the the blacks on the first image is different from the other 3)
Was wondering if this bug is related to the night clock bug or a defect with my unit.
If anyone is willing to help, kindly try changing your wallpaper to a solid black color and check if the blacks on the home screen and lock screen is different.
Thanks! (I have 4 days left until I won't be abe to replace my unit so I'm trying to make sure everything's good)

They're referring to the Night Clock alone. I have that problem as well as a lockscreen problem. Haven't seen anyone reporting if they have the lock screen problem so I'm trying to figure out if it's a software glitch or a bug with my unit.
Basically the lock screen preview when applying a new wallpaper shows that the lock screen should have super amoled blacks but when I lock the phone the black is lit up.

If there's any consolation I experienced this very problem. Were you using fingerprint to unlock? I hadn't seen it because I had swipe to unlock.
I still haven't figured out how to fix it.

That's normal. This happens because the lock screen puts a slight filter on your wallpaper. It de-saturates the image. You can try with a solid red color, it might be easier to see.

Not, really. This only happens when you have Fingerprints/Pattern set up as your Screen lock type.
If you set it to Swipe, with the water droplet effect, there's no "filter."
Someone found kind of a solution to this, but it didn't work for me: http://forums.androidcentral.com/sa...t-rid-dark-filter-lock-screen-wallpapers.html

Yeah it's clearly a bug, but OP thought it might be a defect of his phone. I was just reassuring OP that the problem exists in my phone as well. Thanks for that link. I did try the solution they proposed but it didn't work for me either...
Solution not working...plz another fix?
I have the same bug on my Galaxy J5 (super amoled), I use pin to unlock it. It is pretty annoying. I use the same black picture for both lock screen and background pic, and after unlocking the phone, black backlight turns off. Swipe to unlock solves the problem, but I have to take one of the disadvantages : either backlight or not locked phone.
Download "klwp live wallpaper maker" from playstore and make a all black wallpaper . Save it go to settings ---> background/wallpaper, set KLWP as lockscreen and wallpaper/background.
Not solved? are u using xposed? if so, download Bright Lockscreen and see if this helps.

Screen grey halo beaming from second screen

I might have an issue with my phone. I just wanted to check if anyone had the same problem.
When i have a white screen i get that grey beam coming from the second screen down on the white.
Is that normal or the screen is messed up ?
Also, on the second screen, when i get a notification that has a white background, it seems a little black.

I've noticed the same problem. I think it's due to the secondary screen led not being as brightly lit as the main one. It should look better when the second screen is active.

Screen Problem

So i noticed that on the screen bellow the samsung logo there are like 4 lines/layers the first line its like brighter than the screen should be second one goes darker third one goes even darker and at 4th one it pretty much disappears theres light on the layers and i though its a bug with my system so i just went in download mode and the lines still stay there and on the 2nd and 3rd line theres like a print of the facebook app theres two icons just sitting there it has been there for like a week and i just wanted to ask since i was watching this video and its also a good way to explain it
https://www.youtube.com/watch?v=fmqSMJf_rLE at 10:53 so on my phone its like facebook got burned in the screen but its really really unnoticable you have to be like on a full white wallpaper to see or some games that have bright colors what could this be from?
