Hopefully someone can help with this. My S8+, when connected to my uconnect stereo in my truck, sends an autoreply sms saying I am busy when I hit the answer key on the radio. I've checked the setting for do not disturb and can't find anything on auto reply messages while driving. I can call someone with no issues but can not answer the phone.
Sounds like a ‘Do Not Disturb While Driving’ mode is implemented either on your phone or your radio. Are you using any particular apps, such as Android Auto?
