Q：

1.I just installed your android display, but when using bluetooth to talk, the other party can hear my voice, but I can't hear the other party's voice.
2.When using bluetooth calling, I can hear the other party but they can't hear me.

A:

This situation is usually because the phone is connected to other devices, switching the Bluetooth sound to other devices, which is why the call is abnormal. You need to remove the other devices from your phone and connect only Android Bluetooth.
