Did you know that the Apple icon on the back of your phone is actually a tool that can be used? Why is this not more well known, you ask? We have no clue. Here's how to program this cool trick. Go to the Settings App on your iPhone and select "Accessibility." In the "Accessibility" section, select "Touch." From there, scroll to the bottom of the screen and select "Back Tap." Select "Double Tap" or "Triple Tap" depending on your preference. Set the amount of taps to correspond with different actions, including screenshots. You can also choose from accessibility features like "Magnifier" and "VoiceOver."
