Solution:
1. Check whether there is power in the brand. If the power is low or not, please try it after recharging.
2. Check whether the distance between the band and the mobile phone is too far. Please try to put the band as close to the mobile phone as possible.
3. Mi Fitness/Zepp Life APP was upgraded to the latest version, and the band was restored to the factory and tried again.
4. Mi Fitness/Zepp Life App shall open the location permission and clear the bluetooth data of the band in the bluetooth of the phone;
5. Restart the bluetooth of the phone, restart the "Mi Fitness/Zepp Life" App, and try to restart the phone.
6. Check whether there are too many bluetooth or WiFi devices around and try to change the environment.(both bluetooth and 2.4ghz WiFi operate in the 2.4g band, so it is suggested to connect the mobile phones to 5g WiFi or temporarily turn off the mobile WiFi, and change to other environments without routers or with fewer routers).
7. Try to replace other mobile phones to eliminate the problem of mobile phones.
8. If the Mi band has been bound before, it needs to be unbound in the previous device before binding the new phone.
