How to send secret words on Xiaomi's mobile phone

1. Enter the SMS interface, press and hold the search box above and pull down until the lock icon appears.

2. At this time, a privacy setting will appear below. Click enter, click add private contact, and a prompt will pop up, asking you to add it manually or choose from calls and contacts.

3. Take choosing a contact as an example. After selecting contacts (select one or more), click OK.

4. Return to the privacy settings page, and you can see that the contact is set as private. If you want to delete it, just click the-sign at the back. After it is set to private messages, family and friends can't see these private messages even if they look at your mobile phone.
