With a Samsung S22 book cover or Samsung S22 2-in-1 case, you can protect the front and back of your Samsung Galaxy S22 smartphone. The cases open like a book. A 2-in-1 case is a combination of a back cover and a book case. The back cover is easy to detach and attach with a magnet. That way, you can use your smartphone in the back cover when you're sitting on the couch and you can click it in the book case when you're on the go. Do you frequently drop your smartphone? Choose a case with fall protection.
