For my many smartphones Vergnangenheit I have tested and used many covers or cases. The safest and most qualified so far is the Spigen. It is extremely stable and protects the device from knocks and drops. The rubber bead, which protrudes over the edge of the display is very effective and the metal back wall is very resistant. Unfortunately, the phone loses its slender and delicate character through the shell. But that's the price one has to pay for the protection. Overall a very good protection!
