When I used a Bluboo Maya Max, with Android 6:
podcast app: Podcast Republic
audio device: bluetooth headset MEElectronics Air-Fi Matrix2 AF62
Condition: playback is normal, fine, good
Blackview S8 Build V1.0-20171102:
podcast app: Podcast Republic AND Castbox
audio device: bluetooth headset MEElectronics Air-Fi Matrix2 AF62 AND Blackview earbuds using Blackview USB-C adapter
Condition: playback stops every 10-20 seconds. Half of those times, there is a chime/doorbell sound. The podcast app playback shows paused. I can hit the play button and it will start again. This playback interruption does not happen when I listen to webinars hosted by Peachtree Media. But it does happen with those two podcast apps.
