Oppowatch2 watch is too healthy, but once it exits the background, how to disconnect it?

Solutions include: checking the connection state between the watch and the mobile phone or explicitly applying the cache.

1. Check the connection state between the watch and the mobile phone: Open the settings application of the watch and select "Bluetooth" to ensure that the Bluetooth connection state between the watch and the mobile phone is normal. If the connection status is not normal, you can try to reconnect.

2. Clear the application cache: Open the setting application of the mobile phone, select "Application Management", find the Huantai Health Application, and select "Storage Space" to clear the application cache. Then reopen the application to see if it can solve the problem.
