If you have owned an iPhone for very long, you know its response to tapping that home button tends to slow down. Roberto Garza shared an easy way to recalibrate the button and restore its factory performance. It takes about 15 seconds to accomplish, and your iPhone's home button should go back to responding immediately! Head over to the Snap Guide for step by step details. I know it sounds a little odd, but it absolutely works. (Trust me. I tried it on my own iPhone!)
