Shake Your iPhone to Undo Something
This is actually an accessibility feature, but it’s pretty useful once you start using it.
As it turns out, your iPhone has an undo function that you can use simply by shaking it. Yes, you literally have to shake your iPhone, and it will know you want to undo whatever you did on screen.
For instance, you can shake your iPhone, and you’ll have the option to delete something you just wrote, re-open a tab in Safari, or mark a complete reminder as incomplete.
The downside is that if you move your iPhone too abruptly, it will think you want to undo something, so you might get the message on your screen. If you don’t like this feature, you can disable it by doing the following:
- Open the Settings app.
- Scroll down and go to Accessibility.
- Go to Touch.
- Scroll down and disable Shake to Undo.
