With a 2-in-1 case, you can protect your smartphone form scratches and bumps. A 2-in-1 case is a back cover and book case in 1. It's possible to easily click the back cover out of the book case. That's useful if you make a call or take a photo, for example. In the front flap of the book case is often a card holder. This allows you to store your cards, so you'll always have them at hand. Most 2-in-1 cases are relatively thick. Choose your smartphone model here and view all 2-in-1 cases that are suitable for your device.
