Why does Xiaomi mobile phone always show that synchronization is unsuccessful? I didn't do anything. I showed myself inexplicably.

Synchronization can only succeed if there is a network.

The reasons for the failure are as follows.

1: No data network.

2: No Google or Xiaomi account.

3. All of the above, that is, the network firewall prevents the above programs from networking.

Actually, it doesn't matter if it's not synchronized. Failure can be ignored. If you don't want him to display it, you can pull down the screen and turn off synchronization.
