If b.ring’s control function isn’t working temporarily, you’ll need to check your smartphone’s OS permission settings and the app’s state.

1. Check smartphone permissions: The smart ring’s control function uses the smartphone’s background media permissions. In your smartphone [Settings], make sure both “Notification access” and “Device control permission” for the b.ring app are turned on.

2. Update to the latest version: Media control functions depend heavily on compatibility with the smartphone OS (Android/iOS) version. Please update the b.ring app to the latest version in the Google Play Store or App Store.

3. Report errors: If it doesn’t work with certain media apps (e.g., a specific music streaming app), or freezes after a specific button press, please send the symptoms (screen capture or description) to customer support so our development team can work on compatibility improvements.
