Phone Cover BPC-15

These fulfill both the role of cases and protectors. Typically made of leather, they wrap around your phone. They protect the back and cover the front when you're not using the device. There are also wallet covers, which include flaps for money and credit cards.

If you're good about keeping it clean so dirt and grime don't build up between the phone and the case, a smartphone cover will usually do a good job of protecting the phone from scratches.
