I have a nokia 6.1. So far I've been really happy with it, the phone is really good for the price, but since the Android Pie update, when I switch to dark mode in apps like Youtube or Messages, etc... the navbar(the bar with the navigation buttons) doesn't change color, it remains white. I really want to use dark mode but the contrast between dark and white ruins everything. I heard it might be because of OLED screens, but my phone doesn't have one... Any help please? Thank you!
