Hello Everybody,
Thanks to your feedback we've found an issues that when Bluetooth is turned off, the phone crashes, freezes, or resets. There are two ways to hit this.
- Turning Bluetooth off through the toggle in the Settings App
- Turning Bluetooth off via Quick Action toggle
If the phone's UI freezes, this is because the UI is waiting for the radio to be turned off in the background. Leave it for a minute, and the phone should recover. If not, you will need to reset your phone to recover.
We apologize for any inconvenience this may cause and are actively working on a fix and servicing it as soon as possible. If you have hit this, please file feedback through the Feedback Hub.
