S7 edge black color issues

[Strrongershawn]

So I noticed when I am watching or seeing pictures, there are darker black display in some pictures when it displays a black color in it. I am not very good at english so I will just show it to you. The yellow circles show where I can see the dark black display. Is this normal? What can I do about it? Thank you in advance.

Typical for a OLED screen to have black like that. the screen actually turns off pixels to create a full deep black color that you won't find on the average backlit lcd panel. it's also a way to save some battery, if you choose to have a black background or theme.
