I've had a galaxy s20 plus for about 3 months now. I'm trying to connect 2 or 3 headphones on separate occasions through bluetooth and they work completely fine for music, videos etc. As soon as I try to make a call they disconnect and reconnect every 5 seconds or so. I've tried resetting bluetooth, the headphones, hard resetting the phone. Nothing has helped. I connected them to another phone and can make calls no problem. I haven't seen another post about this problem. Please help!
