Protects the Smartphone not as hoped

The processing of the leather case is good and also visually appealing. However, this type protects bag not as I had hoped. When I fell off my smartphone foolishly once, it came exactly on the spot on the ground, which is not protected (the top of the opening). Now the plastic of smart phones is easily damaged at this point. Otherwise luckily nothing happened. Should I someday have to organize a new smartphone pocket, I'm such a choose in the smartphone "sinks" and free at any point to the outside world is.
