Bluetooth issues

Hi,

me and a lot of friends are having problems with our bluetooth. All the iPhones after 12. Disconnect and connect Bluetooth automatically during the call. We use air pods, even that keeps resetting. And they block our screen, it’s not possible to switch off or just put the call on a speaker mode. It happens every 1, 2 or 3 minutes. It’s impossible to have a conversation using phone Bluetooth more than 10 minutes. It’s very uncomfortable. I’ve tried a lot of different brands. Still doing the same. Apple should fix it.
