After years of user requests, Apple has finally beefed up Messages with a few welcome features—options to mark conversations as unread for later reference, edit messages after they’ve been sent, and undo sending entirely. Plus, when you delete junk texts in Messages, you can now report them to Apple and your carrier, and you can find inadvertently deleted conversations in Recently Deleted. Finally, there’s a Tapback improvement for SMS messages to Android users.
Before we begin, beware that editing messages and Undo Send work the way you expect only if your recipient is also using iMessage (blue bubble friends) with iOS 16 (or iPadOS 16 or macOS 13 Ventura, once those come out later in 2022). Instead of an edited message, a device running any other operating system will display a second message with the edited text. An unsent message can’t be called back from a recipient not running iOS 16—it will remain in the conversation with no indication that you tried to unsend it.
