You can delete an individual and a group chat history. This clears the chat history on your device – but the other person will still be able to see the chat.
- Select the group or individual chat that you want to clear.
- Select the chat's avatar, then select Settings.
- Select Clear Chat History (or Clear history).
- Select Clear in the confirmation box that appears.
Once you’ve cleared your chat history from your device, you can’t recover it.
