Mine randomly restarts, sometimes it is like a flash and other times it takes longer. The radio, phone and SiriusXM don't hold faves or settings and Android Auto not always connects on the first try. I will schedule a dealer visit to have it looked at soon.
Same here, the connection issue is random, but the deteriorating and yellowing image issue went away with the latest update on the Pixel 2 (mid June I think) is yours up to date?
