The companion app in connection with the Intent seems to be behave flaky , see here
Maybe Oticon need to bring updates for the Companion App and for the Intent hearing aids.
I’m on Android 12 (Xiaomi) and have Real HA, and sometimes, very seldom, it happend that one of the hearing aids rebooted after i opened the Companion app.
But I seldom open the app, only if I am check the battery.
Since the latest firmware upgrade for the Real HA and the last update of Companion app the rebooting did happen only once.
And i have also installed MyPhonak app on the phone. So this works OK.
About the Oticon TV Adapter, this works like the Phonak TV Adapter, sound wise the quality via Oticon TV Adapter is the same as with Phonak.
