After a quick Google search, I learned you can disable the Pixel stand app under settings and you never have to worry about it again. Not sure why this isn’t in the normal settings. My P6P will still charge as normal on the stand minus all the bells and whistles of the stand of which I don’t need.
I use a Pixel stand at work. I hate the fact that the Pixel Stand app automatically assumes everyone wants their phone to turn into a clock while charging. Meaning the display stays on to show the time. I believe the phones sensor can detect light/darkness and will keep the display on unless the room is dark.
