An update to your phone's operating system can result in connectivity issues. To resolve this issue, reset the connection between the shaver and the app by following the steps below:
1. Unpair shaver: Press the on/off button on your shaver for 10 seconds to disconnect it from the app. When your shaver is successfully unpaired, the Bluetooth symbol on the shaver will appear.
2. Unpair phone: Go to "Settings" on your phone and select Bluetooth. Then select the shaver S7/S9 and select "forget" or "un-pair".
3. For Android phones, ensure that you enable location permissions or nearby devices permissions.
4. If you're still experiencing connection issues, try a hard reset. Press the on/off button on your shaver for 30 seconds.
Now you should be able to pair your shaver with your phone again. Turn your shaver on to activate Bluetooth while pairing. Open the app and follow the instructions to start the pairing process. It may take up to two minutes for the connection to establish.
Note: These instructions may differ by smartphone. Please check your phone manual for more information.
