A. 1. Ensure that both the app and the device firmware are updated to the latest versions. Check the app store for updates and the manufacturer's website for device firmware updates. 2. Check the Bluetooth settings on your Android device. Go to Settings > Bluetooth, and ensure that the device is paired correctly. If necessary, unpair and re-pair the device. 3. Reduce interference by moving away from other electronic devices that may cause signal disruption, such as microwaves or Wi-Fi routers.
B. 4. Restart both the app and the device. Close the app completely and turn off the device, then turn it back on and relaunch the app. 5. If the issue persists, try resetting the device to factory settings, but ensure to back up any important data first.
