Android Connectivity

Many Android devices are highly customizable in how you can configure the device settings (particularly in extending battery life), which adds great value to the user experience - but can present challenges in staying connected with any Bluetooth device. 

Pairing:

For instructions on how to pair your watch with your phone, here is a YouTube Video (How to Pair with Your Phone or the COROS App) created to walk you through that process.

If you happen to have any issues with pairing the device with your phone, check out our article (Can't Connect the COROS Watch with Your Phone) that offers some troubleshooting suggestions.

Troubleshooting Connectivity:

While we will not be able to comprehensively cover all situations where the compatibility between your COROS watch and Android device are causing problems, we did put together a list of things we can do on our end to ensure the best connection possible.

Please make sure to update the Android system version once new updates are available. The COROS engineering team is also in contact with the Android team for this matter. Please check the following:

1. Ensure the COROS app is excluded from the Battery Optimization List

   • Android phones running Android 6.0 or later will kill background apps automatically in certain circumstances. This may cause your phone to terminate the Bluetooth connection with your COROS watch. To prevent this from occurring, please check the "Battery Optimization List" in the settings of your phone and make sure that the COROS app is excluded. On some devices, you may be able to find this setting under Battery Settings > Unmonitored Apps
     
     

2. Check Location Services & Permissions

   • To Check Location Services: This may be located either in your App settings or simply in your location settings. Please refer to your manufacturer's instructions if unsure.

   • To Check COROS App Permissions: This will likely be under System/Android Settings > Apps. Please refer to your manufacturer's instructions if unsure.
     
     

3. Disable background Bluetooth on similar apps

   • Other apps of similar types that have background Bluetooth sync features can interfere with a stable Bluetooth connection, please disable all background Bluetooth features on other apps. An example of a similar app would be Fitbit.

If the settings above have been checked and you are still having trouble, please try the following:

1. Remove the watch on the COROS app.

   • From the COROS App: Device Page (watch icon) > Tap on your Device Name > Tap Remove

2. Force Stop the COROS app.

   • System/Android Settings > Apps > COROS > Force Stop

3. Clear the COROS app storage.

   • This should be accessible from the location noted above

4. Forget/Unpair any/all COROS devices in the Bluetooth settings on your phone.

   • This can generally be found under System/Android Settings > Bluetooth Settings > Choose the COROS Device or tap the "i" next to it > Forget/Unpair

5. Turn your phone OFF (DO NOT RESTART)

6. Wait 15 seconds

7. Turn your phone ON

8. Pair watch with the COROS App:

If that does not resolve the issue, you may be able to find a temporary fix by doing the following:

1. Remove the watch on the COROS app.

2. Restart the phone.

3. Enter airplane mode on your phone.

4. Enable GPS/Location services.

5. Wait for 30 seconds and exit airplane mode.

6. Manually Pair the watch on the COROS app via “Pair COROS Watch Manually” instead of scanning the QR code.
