Hi there! I understand that after resetting your 3 Plus HR Plus device, it's no longer connecting to your mobile. Let's work through this together.

To get us started, can you tell me if you've already tried turning Bluetooth on your Android phone off and on again? And have you unpaired or forgotten the watch from your phone's Bluetooth settings if it appeared there previously?

Assuming those basic steps still need checking, here’s a step-by-step guide to reconnect your device after a reset:

1. Turn on Bluetooth on your Android 10 phone.
2. Make sure your 3 Plus HR Plus watch is charged and powered on.
3. Open the 3Plus Elite Series app on your phone.
4. In the app, go to the device list and if your watch shows up, select it. If not, follow the app's prompts to scan for devices.
5. If the watch was paired previously, you might need to "Unpair" or "Forget" it from your Bluetooth settings on the phone to allow a fresh connection.
6. Allow the necessary permissions for Bluetooth and location from the app. These are often required for successful device discovery and pairing.
7. Try pairing again through the app.

If the watch still won’t connect:
- Restart both your watch and phone and repeat the steps above.
- Check that the 3Plus Elite app is updated to the latest version compatible with Android 10.
- If you previously had the watch paired with another device, ensure it’s disconnected from there too.
- Lastly, if the problem persists, you might want to reset the app’s data: go to your phone’s Settings > Apps > 3Plus Elite App > Storage > Clear data, then restart the app and try again.

Let me know what happens after these steps, and we can dig deeper if needed!

Are you able to see your watch in the app’s device list at all right now?
