If you’ve been waiting for this feature to arrive, then you’re in luck. Facebook has begun rolling out its “unsend” feature in its mobile app. You now have 10 minutes after you send a message to remove it from a conversation. All you need to do is long-press or tap on the message you want to delete. This will show you two options that are self-explanatory: “Remove for Everyone” or “Remove for You.” It’s already made its way to our Android device, so just keep an eye out for it.
