Add Members to a Contact Group auf Huawei
Contact groups on a Huawei phone are managed inside the Contacts app, not through a separate address book. New members are not locked in once a group is created; you can extend the list at any time without rebuilding it.
To add people, open Open the Contacts app ➔ Tap on Groups ➔ Choose a group. Inside the group, tap Tap on Add members, then Select the contacts to add. The list supports multi-select, so you can tap several names before confirming with Tap on Add.
This is faster than editing each contact individually and searching for the group name under their profile. It also avoids duplicate entries, since contacts already in the group are grayed out or hidden from the selection list.
If a contact does not appear in the selection screen, check whether they were saved to a different account (for example a separate email account instead of the phone or cloud account) since group membership only applies within the same contact source.
