While working from home, I need go to pick up my son from school.
Using Android Teams application, and while on a teams meeting or a teams call, my headset stays connected until I start my car engine.
This is the time when sporadically the app switches me to car Bluetooth or keeps me connected on the headset.
The options I see on Android teams app while I have multiple active Bluetooth connection are:
If Teams already switched me from headset to car Bluetooth the only way I can get back the sound on the headset is from car menu (to disconnect car from phone), or from Android menu (disconnect phone from car) , but there is no control in Teams app.
My ask for the community: should we be able to see all Bluetooth active connections to choose from and get control back?
It sounds like your car and phone are connecting at the point you switch on the engine. At that point the cars Bluetooth is creating a link with your phone and taking control. Try disabling Bluetooth in your car then your BT connection with your headset/teams will continue.
