What is the use of cloud services in Huawei mobile phones? What's in it?

Huawei's cloud service functions are as follows:

1. Automatically synchronize photos, contacts, text messages, call records, memos, recordings, calendars, harassment interception, WLAN data to the cloud, or synchronize/download cloud data to mobile phones.

2. Find my mobile phone to help locate your mobile phone, and you can remotely control the mobile phone (erase data, send short messages, lock the device, and play ringtones).

3. Buy more space capacity/buy more cloud storage space.

4. Cloud backup: backup all the data in the mobile phone with one click. (Note: EMUI5.0 version 5.0 below 5.0 has no cloud backup function. )
