My favorite use of the back tap accessibility feature in iOS 14
You can set a number of nifty things to happen when you do a double or triple tap on the back of your iPhone using iOS 14. This is probably my favorite: scroll up and down. It’s the best parallel I’ve found to turning a page on a screen (other than an eink touchscreen). For reading, it’s great. It’s a predictable, consistent speed that your eye can follow and your finger doesn’t get in the way or accidentally tap something, and helps me focus that much more on what I’m reading.

You’ll see the difference between using the back-tap at the start of the video, versus dragging the content with your finger at the end.
