17.Why doesn't BTR3's mic support phone recording and send voice messages with WhatsApp/Facebook?
A: When the BTR3 is paired with the Android mobile phone, the voice of the software such as WhatsApp can be normally listened to, and the microphone of the call is normally used. But when using mobile phone recording and sending voice messages with WhatsApp/Facebook, we're using the phone's own microphone, and the BTR3's microphone is invalid. This function mainly depends on the support of the mobile phone system itself and compatibility with third-party apps. For example, when paired with some Apple phones (iOS), it supports WhatsApp/Facebook to send recordings, voice messages and voice calls.
