Xiaomi: Add Contacts to a Group

Newly created groups on your Xiaomi phone remain empty until you assign contacts to them yourself. MIUI ties group membership directly to the Contacts app, so there is no separate group manager working on its own.

To add someone, go to Tap on Contacts ➔ Open the Menu ➔ Choose a Group ➔ Tap on Add. In the list that appears, Tap and hold a Contact to select it, then If desired, select more Contacts to build the whole group in one pass. Confirm with Tap on Save and the new members show up immediately in the group overview.

This same process covers both call groups and message groups, since MIUI treats them as one contact set with different notification rules layered on top.

If a contact does not appear in the selection list, check whether it is stored locally or only synced through an account that is currently signed out. Contacts hidden by an active filter, such as a SIM-only view, will not show up either until that filter is removed.
