Display issues on home screen - Samsung Galaxy S8 Questions and Answers

Does anyone know how to remove the gray tint on my home screen on the image attached? I just noticed it yesterday and when using a widget for Circle Launcher, it has a black bar. I think that one is due to the screen resolution but I cannot change it to full screen in settings. It does not show up in the list. This one also just started happening.

Small 'Today' Problem

on the htc4350/herald you usually have 4 small icons which leads to the Battery, the thing that flips the screen, another icon thet leads to the comm manager and the 4th one for the backlight and that stuff.
now what happened to me is that the first 2 icons dissappeared but if i tap on the wallpaper exactly where the icons used to be, they still work.....how can i get those 2 icons back? (the battery icon and the flip screen icon)
thanks
I'm not sure if you've fixed this problem since the post is so old, but if it does happen to you do this:
1. In TODAY SCREEN ITEMS, Edit the HTC Plugin Icons to NOT APPEAR on the Home Screen. Exit the TODAY SCREEN ITEMS and reset your device.
2. Go back to TODAY SCREEN ITEMS and put the HTC Plugin Icons back. This should now enable all four of those icons to appear on your screen. Doing this and moving them up and down will enable it to re-apper!

Screen burn-in

Just realised when I looked closely at the white background of the email hub, the white icons on the main menu tiles have burnt faded-yellow outlines into the screen, most likely because I had the screen setting set as "always on".
Can I fix this by placing the phone on a plain black screen for a good while? Or even switching it off?
Cheers
I didnt think the omnia 7 had a always on setting? I had a screen burn problem too: http://forum.xda-developers.com/showthread.php?t=973337
Thanks for the link to your thread comera. Your screen burn-in was crazy big! Mine is just a few white bits from the main screen icons. They are only visible on a completely white screen and since I use the dark theme it doesn't really matter. They are very, very slight anyway.
The screen off "never" option is a registry edit. It has proved useful on occasion but I made a mistake one night and forgot to switch off the option and also the screen. Ah well.
If anyone wants to enable the option then here is the code but please be careful with it.
Code:
[HKEY_LOCAL_MACHINE\ControlPanel\Lock] "DisableNever"=dword:0

Weird G2 screen problem

I've seen a G2 that has a slight blue glow under back and menu buttons, and ONLY when you select the WHITE NAVIGATION BAR. Once you change to a black one or go to home screen where it's transparent there is no blue.
It was on stock rom. Why is that? Is that a screen, rom, digitizer problem? I don't get it, google search shows 0 related problems.
Edit: That's not the phone in the picture, but you get it how it looks

How to make scrolling wallpaper center on the home screen? (CM12.1)

I have 1+2 with unofficial cm rom.
When I set a wallpaper like configure the position of it, it will always appear on the most left screen. I have 5 screens total the one in the middle is my home screen. How can I make it so that when Im adjusting the picture while setting the wallpaper I can make it appear it on my home screen instead the most left screen?

Screen flickering when using parallax wallpaper

This weird screen behavior was observed when I first used a parallax wallpaper application (FYI - it's the 3D Parallax Background by Vinwap).
When I set my moving wallpaper to an image that depicts a starry sky (i.e. lots of white little dots that subtly move when tilting the device), I noticed that the screen would show some visible horizontal flickering at the same area the sky sits.
The effect gets more noticeable as the brightness gets increased. For your reference, I attached a screenshot of my wallpaper to demonstrate what kind of image is required to replicate the issue.
Any ideas on why this issue might occur? Is it a common thing across AMOLED screens, or just another problem with OnePlus 5 panel configuration?
