What is your most favorite/least favorite feature of the Android Pie upgrade? My favorite is the screen rotation toggle they added to the bottom right when you rotate your phone (see pic below). I never leave my phone set for auto rotation, because when I lay the phone down on the desk, it rotates when I don't want it to. This feature is fantastic! Least favorite - the change made to the auto WiFi "ON" feature. Before Pie, when I left an area where an "auto connect" WiFi is, I am pretty sure that my WiFi would turn off, but now it stays on when I leave the house.
