Rename Contact Group auf Samsung
Samsung's Contacts app lets you sort contacts into groups, but the rename option only works for groups you created yourself. Default categories such as Family, Colleagues or Friends are locked by the system and always keep their original label.
To rename a group you added manually, open Contacts ➔ Open the Menu ➔ Choose a Group ➔ Tap on Edit. Tap the current group name, then Enter a Name and tap Save to confirm the change.
If the Edit option is missing or greyed out for a group, that group is a default one and cannot be renamed this way. In that case, create a new group with the name you want and move the affected contacts into it manually.
Renaming only changes the label shown in the group list. It does not affect any contact details, phone numbers, or the calls and messages already linked to those contacts.
