If you’ve made a mistake typing on an iPhone, or accidentally deleted a bunch of text, you might be wondering: Can you undo it? The answer is usually yes, and there are at least four different ways to do it. That is how.
shake to undo
The oldest method of undoing text input is called “Shake to undo”. Apple introduced it in iPhone OS 3.0 back in 2009 and made it possible to disable it in iOS 9. While the feature has been enabled for many years, it may be disabled on your iPhone by default on newer models.
To use Shake to Undo, first make sure it’s enabled. Open the Settings app and navigate to Accessibility > Touch, then toggle the switch next to “Shake to undo” to the on position.
After that, the next time you’re typing and need to undo something, physically shake your iPhone. When you see the “Undo Typing” popup, tap “Undo”.
If you find that you keep accidentally triggering the “Undo Typing” dialog, you can disable “Shake to Undo” by visiting Settings > Accessibility > Touch and turning off “Shake to Undo”.

Three-finger tap to undo (two methods)
There are two ways to undo text input errors with tap gestures on your iPhone screen. While typing, double-tap the screen with three fingers. You will see an “Undo” notification at the top of the screen and your last action will be undone.
Also, in many Apple apps (and some others), you can open a formatting bar by tapping the screen once with three fingers. This bar provides a visual interface for undo, cut, copy, paste, and redo. When it appears at the top of the screen, tap the undo button, which looks like a left-curving U-shaped arrow.
At any time, you can reopen the format bar and redo what you just undid by tapping the curved arrow pointing to the right.

Three-finger swipe to undo
You can also perform an undo action by swiping your iPhone screen. To do so, place three fingers on the screen and swipe left. You will see an “Undo” message appear near the top of the screen and your last action will be undone.
To redo (take back what you just undone), swipe right on the screen with three fingers.
Command + Z on a physical keyboard
If you have a physical keyboard paired with your iPhone, you can use the keyboard to undo text input in many apps. To do so, press Command + Z on the keyboard. To redo, press Shift + Command + Z. These are the same keyboard shortcuts you’ll find on the Mac.

Undo in other applications
While the above methods are supported by most Apple apps, some third-party apps may not support them. If that’s the case, look for a custom “Undo” button (or an icon with a curved backwards arrow) somewhere in the interface. You can also try shaking your iPhone to undo, which is supported by some developers. Good luck!
