To turn the Apple logo on the back of your iPhone into a secret button when you double tap or triple tap it, follow the steps below:

1. Open Settings on your iPhone
2. Tap on Accessibility
3. Tap on Touch
4. Tap on Back Tap at the bottom
5. Tap on Double Tap
6. Select the shortcut you want to happen when you double tap the Apple logo
7. Tap on Back Tap at the top of your screen
8. Tap on Triple Tap
9. Select the shortcut you want to happen when you triple tap the Apple logo.

Once you have setup Back Tap, using the feature is very easy. You just double tap or triple tap the back of your iPhone around where the Apple logo is. It works even when you have a case on in our experience, though we haven't tried it with all cases of course.

You don't need to push the logo, just double or triple tap the logo with your finger and the shortcut you have selected for that action will happen straight away, whether a call or a screenshot.

Note: If you have a case on, you may just need to make a note where the Apple logo is on your device. For the iPhone 11, 12 models, iPhone 13 models and iPhone 14 models, it is in the middle of the rear for example, while on the iPhone XR, it is above the middle in the top third. Back Tap should work when you tap anywhere on the back of your iPhone though.
