STRANGE DISPLAY QUALITY
I think I have some problem with the display.
1) When I touch the fingerprint scanner to unlock the screen or an app the display change its contrast or something like that.
2) Whenever I scroll down (or up), I get this kind of purple drag, but this is only visible with black images.
3) Overall the screen quality seems poor on low brightness, not uniform and with a strange textured feeling on gray colors.
Am I the only having trouble with these problems?
