Why will my Note 20 not connect to my car radio thru USB? My son's iPhone connects fine and streams whatever he wants, this is VERY frustrating! Tried the debugging thru developer options and audio is not an option. I'm not sure why Samsung won't allow us to stream our phone to the radio like Apple does without issue
Check your notification area. There should be a banner titled "Android System", and it most likely will say "Charging this device via USB". You have to tap that and switch to MTP or PTP.
