At android 8.0 the s7 edge phone does not turn off the display, maybe he warns me to give some permission to the android Auto app what I tried to use unsuccessfully. I can't find where I should be allowed anywhere, Android Auto gets all the licenses, sometimes (very rarely) instantly connected to the car, but most often not after multiple attempts. What should I do to solve the problem ???
