Why is my brightness so low?

[Android Central Question]

I have Honor 8 Pro, Android Oreo, and my maximum brightness is too low. When I move the brightness scroll bar, the brightness is increasing up to 80%. Then when I move the scrollbar from 80% to 100%, the brightness doesn't change. What am I doing wrong? Thanks

Welcome to Android Central! Have you tried restarting the phone to see if this was just a glitch? Are you using any dark or neutral-coloured wallpapers, launchers, etc? Does this brightness issue affect all apps or just a couple?
