Can you add the ability to record audio via the USB or the 3.5 mm port on an Android mobile device. Other audio recording and video apps (Filmic and Recorder)on Android are able to grab the audio via 3.5 mm port or the USB-C port or bluetooth. The dubb app only records through the built-in mic on Android Google Pixel smartphone. 
This will allow for a greater usage of the dubb app for professional and enhanced audio. The better the audio the better our customers and potential customers can appreciate the video messages.
Allowing the dubb app to record for these ports would allow audio to be sent via professional microphones, headsets and allow for hands free usage rather than holding the mobile phone when recording.
Thanks for your attention.
