Explanation:
First, determine whether the contacts, messages, and photos are added or reduced directly through the cloud, or are added or reduced by other means, such as checking the storage path, storing accounts, and whether it is possible to synchronize other accounts, etc.
If it is confirmed that it is under the xiaomi account, which is added or reduced in the cloud service, it shall be handled according to the following ideas:
1. As long as a mobile phone or other terminal device logs into the same xiaomi account and starts the synchronization function of xiaomi cloud service, the data will be synchronized to the same server and the data will be merged together.
2. If contacts, text messages and photos appear or are lost without reason, the greatest possibility is that xiaomi account logs in on other terminal devices.
3. It is suggested to visit mi.com to see if there are other devices besides their own mobile phone connected to the device. If there are, delete them.
4. In addition, it is suggested to change the password of MI account no matter whether there are other connected devices.
