My S8 has within the last month started having a very weird issue with phone calls. Sometimes I'll be mid-call and abruptly can't hear the other person and they can't hear me. The line doesn't drop, just the audio and the mic. If I hang up and call them back, the problem is fixed for a time before happening again. It's happened usually around 15 minutes into a call and can happen multiple times in one conversation.
I'm not connected to any bluetooth devices. It happens probably once every 3 or 4 calls.
Anyone know what could be causing this? Or how to fix it?
Thanks in advance!
