Leaving in Google Messages: the RCS condition

Open the group, tap the three-dot menu, choose Group details, and select Leave group. That option only appears if RCS messaging is active for the group and for every participant in it. If even one person is texting over plain SMS, the option won’t show, no matter how you’re connected (Samsung Members).
Can I leave a group text without the creator’s help?
In Google Messages, yes, if the group runs on RCS with every member enabled. In Samsung Messages, or any SMS/MMS-based group, no; only the group’s creator can remove you.
Samsung Messages: there’s no leave button, and there wasn’t one

Samsung Messages has no setting that lets a member remove themselves from a group someone else started. The app’s own community support threads confirm the only self-service options are muting notifications or deleting your local copy of the conversation (Samsung Community).
What to do instead

If leaving isn’t available, three real options remain, and they don’t do the same thing.
| Action | Stops future messages? | Keeps history visible? | Reversible? |
|---|---|---|---|
| Mute | No, still received silently | Yes | Yes, unmute anytime |
| Delete conversation | No, new messages recreate the thread | No, local copy gone | No |
| Ask the creator to remove you | Yes, once they act | No, access lost | No, re-adding needs a new invite |
The three don’t substitute for each other: muting silences a group you’re still in, deleting clears your screen without stopping delivery, and only removal by the creator actually ends your membership.
To mute in Samsung Messages: open the group, tap the three-dot menu, then tap the bell icon. To request removal, message the creator directly rather than posting in the group itself, something like: “Hey, can you take me off this chat? I’m not able to leave it from my end.” Naming the specific ask avoids a vaguer post that gets missed in a busy thread.
What happens to my message history if I switch to Google Messages?
Samsung says conversations transfer automatically when you switch, though the full transfer can take up to about 24 hours depending on how much data is involved (Samsung).
Samsung Messages is being retired, which resolves the question differently

Samsung is discontinuing the Messages app in the US on July 6, 2026, for anyone running Android 12 or newer; devices on Android 11 or lower are explicitly exempt from this cutoff (Samsung). Once the app is discontinued, it stops sending messages entirely except to emergency contacts and services, so the group-chat question mostly resolves itself for anyone who migrates. The Galaxy S26 line never had the option in the first place: it launched unable to download Samsung Messages from the Galaxy Store at all.
Do I need to do anything if I’m on Android 11 or older?
No. Samsung’s end-of-service notice specifically excludes devices on Android 11 or lower from this shutdown.
Which app am I using, and does leaving apply to it?

| App | Group created via | All members on RCS? | Leave available? |
|---|---|---|---|
| Google Messages | RCS | Yes | Yes, Group details > Leave group |
| Google Messages | RCS | No, mixed SMS/RCS | No, option hidden |
| Google Messages | SMS/MMS | N/A | No |
| Samsung Messages | Any | Any | No, mute or delete only |
If you’re not sure which case applies, open the group’s three-dot menu: a visible “Leave group” entry means you’re in the first row. Everything else means muting, deleting, or asking the creator are the only paths.
Mixed iPhone and Android groups

Adding an iPhone user to a Samsung or Google Messages group usually forces the whole thread onto SMS/MMS, which removes the leave option for everyone in it, Android and iPhone members alike. There’s no per-platform workaround for this specific case beyond muting or asking to be removed.
Why did I have a leave option before but not now?
Someone likely added a member on plain SMS, or your own RCS connection dropped. The option reappears once every participant is confirmed on RCS again.
