Since the last update for my Galaxy Note9 I can't make calls through the integraded hands free app in my car anymore. Sometimes it will start a call and I'll hear someone then it cuts out, sometimes it won't even complete the call and sometime if I started a call and switch to the handsfree car app I'll talk for a couple minutes and suddently it'll stop working. Very frustrating and annoying!!!!!! Can I backout the last update??
