Shake Your iPhone to Undo Something
Another cool feature is the ability to undo something you recently did just by shaking your iPhone. That’s right; all you need to do is shake your iPhone, and it will ask you if you want to undo something you just typed, reopen a Safari tab, or even move an app back to its original place.
Shake to Undo should be turned on by default, but here’s how you can enable or disable it:
- Open the Settings app.
- Scroll down and tap on Accessibility.
- Select Touch.
- Enable Shake to Undo.
Now you can write a new message or a new note and give your iPhone a good shake. You’ll receive a confirmation window to make sure you want to undo what you just wrote.
