Firmware Update Troubleshooting

If you experience trouble while attempting a manual firmware update, try the following:

• Ensure your ring is connected throughout the updating process — don’t close the app or toggle your Bluetooth on/off while the update is taking place
• Keep your device's screen unlocked during the update to prevent potential interruptions
• Make sure your device’s operating system is up to date. You can check this by opening your phone's Settings
• Restart your phone
• Attempt the firmware update in a room where the signal interference is low (no other devices nearby)
• Attempt the firmware update through a different device (e.g., a tablet)
