A Group Chat Name Keeps Reverting
You rename the group chat, and a day later the old name is back. The name change needs every member on iMessage — one SMS member, or one person who changes it back, quietly undoes your edit.

TL;DR / Quick Fix
Quick fix: open the group info and rename it again, then check that every member shows a blue iMessage bubble. If one member is green (SMS), the name cannot stick — ask everyone to stay on iMessage. Confirm nobody else is renaming it back.
Follow these steps
- Rename it from the group info screen. Open the conversation, tap the group name at the top, then Change Name and Photo. Renaming anywhere else does not actually set the group name.
- Check every member is on iMessage. In the member list, all-blue means iMessage. A single green SMS member blocks group naming entirely — the name field may not even appear.
- Ask the group who keeps changing it. Anyone in the group can rename it. If the old name returns, someone may be changing it back — ask before assuming the iPhone is broken.
- Check the member count. Group naming needs at least three people. With only two, it is a regular conversation, and the name option behaves differently.
- Leave and rejoin if the name will not stick. If settings are right and the name still reverts, leave the group and have someone re-add you. A fresh membership clears a stuck group state.
- Update iOS on your iPhone. An old iOS can mishandle group metadata. Update, then rename once more and watch whether the new name survives a day.

What NOT to do
- Do not keep renaming it five times in frustration. One careful rename with all members on iMessage works; five rushed ones just annoy the group.
- Do not blame the iPhone when a friend changes the name back. The group belongs to everyone, and the change history is social, not technical.
- Do not create a new group just to fix a name. A new group loses the whole conversation history for a problem with a simpler fix.
- Do not expect a name to stick in a mixed iPhone-Android group. SMS groups cannot hold iMessage features like names and photos.
Frequently asked questions
Why is there no name field in my group?
Because someone in the group uses SMS, or the group has only two people. Both cases hide the naming option.
Can I lock the group name so nobody changes it?
No. Any member can rename the group, so the name is a shared choice, not a locked setting.
Does leaving the group delete my messages?
No. Your copy of the conversation stays, but you stop receiving new messages until someone re-adds you.
