People drop their phones all the time. Whether it breaks or not depends on the protective case (or lack thereof) and the build of the phone itself. It also depends on whether or not the user is using a smartphone protection system, like ReelKlip. Most people don’t bother because they can be bulky and a pain to use, but ReelKlip is neither of the two.
It’s a discrete system that basically tethers your phone to where the clip is attached, so it won’t ever reach the ground if you drop it or fall out of your pocket inadvertently when you’re on the go.
