I don't know what's happening but I've noticed that over the last couple of days my adaptive brightness keeps turning itself off during nighttime. Ironically, I don't even have any modes and routines active that warrants this either. I wanted to blame my jeans for maybe toggling the setting off but where do I even start when I hardly keep my phone inside my pockets? It might be a one ui 8 beta defect? Any one else experienced this nuance?
