1. If you have connected your device to a 2G/3G/4G network, the network will be disconnected when you receive an inbound-call. Thus the connection between your device and PC/laptop will be interrupted. You may connect your device to WiFi network and try again.
2. If you're using AirDroid Win/Mac, the connection will be interrupted when the computer goes sleep. AirDroid will restore the connection automatically when the computer connects to the network again.
