Update phone settings for bike activity.
It checks when you're connected to a Bluetooth device (pick up the one you're using on your helmet for example), then:
* Ensures the auto adjustment screen light is on for a better visibility and battery consumption
* Set some volumes (like BT or music) to maximum
* Ensure screen won't turn off during your trip
* Restore settings once you disconnect your Bluetooth device
