On the other side of the fence here. I've been on vanilla Google phones since the Android Nexus. I have a Nexus 6P now, which was the flagship of that generation.

Between Google knowing my porn fetishes and the increasing number of issues & bizarre bugs (severe battery degradation, performance issues during normal usage, random freezes, photos occasionally not saving properly and getting corrupted) plus no security updates after 2 years, I've just about had it.
