Yes I have the Galaxy Z Flip 4 and the first call I make in my car connects and I can't hear the other person. I have to hand up and call right back. Very frustrating.
I just got off the phone with customer service and she seemed surprised. Said someone will be in touch to update. The only thing that's bothering me is not being able to make phone calls. Not happy with that.
Why are some people saying that theirs is fixed? I did a factory reset and unpaired/repaired. I still can't hear the other person when I make the first phone call getting in my car. All other calls are fine after that.
