1. The isolated delivery function in Apple devices is only applicable to file transfer between iPhone, iPad, Mac and iPod devices, while other devices cannot achieve this function. 2. The air separation delivery function may fail when the transmission distance is far or beyond the receiving range.This is because the air separation delivery uses Bluetooth for data transmission. If the distance is too long, the signal will be weak or even unable to transmit. 3. When using the airproof delivery function, the two devices must be in the bright screen state.If a device suddenly turns off the screen, the sender will not be able to send the file successfully, resulting in transmission failure.Therefore, when using this function, pay attention to keeping the device on screen.
