With a back cover you protect the back and sides of your phone. Some back covers have pockets for your cards and some bills. A case of genuine leather not only protects your phone, it also provides a stylish look. Do you want the best protection for your smartphone? Then go for a cover with fall protection: your phone will also survive a fall of small height. A small number of covers has a battery built in; that way you can easily charge your phone on the go.
