So after reading these comments, apparently I'm doing something wrong. When I had my Note 7, I left it on auto brightness which then learned how bright I like my screen for different ambient light settings and would adjust accordingly. With the V20, I can't adjust the brightness when it's set to auto. When I manually set it, then I can adjust accordingly, but if I set it back to auto, it goes back to whatever setting it thinks I would like...which is usually too dark for my liking. Is that normal behavior? After having the Note, this really irritates me.
