How to edit a group's name and photo:
- Go to Settings | Groups & Contacts and tap Edit next to the group. (Or open the group from the Contacts tab and tap its name at the top.) This opens Group Info.
- Tap the 3-dot menu at the top right and choose Edit Group Info.
- Type a new name in the name field, and tap the camera badge on the photo to choose a new group photo.
- Tap Save. Changed your mind? Tap Cancel instead, and nothing is changed.
Edit Group Info is also where you add people: tap + Add next to Members. To create a new group, see Creating and Removing a Group.
