Did you get the green one? If so then you will most likely have to live with the included case until something better becomes available. This is why I went with the black "leather" backed version. It has a plastic back under the leather so if I don't like the included case it can go without one until something becomes available. YMMV
The included case (black one) is MEH at best. I'm not sure that any case maker will be able to do anything much better! The part that covers the back, where the camera carbuncle resides, is OK, the part that covers the front side is not very good. Maybe someone will make a better/stronger one? Glad I got the black one because it doesn't have a glass back and I am going without a case for the first time in memory. YMMV
I'm personally rocking it case free. If I have to use a case I'll just use the one that came in the box. Some of the third party cases on Amazon are just going to make the phone bulky. Personally I like the phone as is.
