Similar problem with my Anker SoundBuds AK-A3233011: as the phone (Aquaris E4.5) connect with the BT device the BT cease to function: I cannot set BT of or set Airplane Mode; even a reboot will never complete, I must force a full shutdown.
The device has some glitch with Ubuntu for desktop, also: sometimes it will not switch from the headset mode to A2DP.
