I have the
Acase Superleggera Pro Hybrid dual layer Case and I love it. It is 2 piece case, the inside is black silicone and the outside is polycarbonate and locks the silicone tightly around the Nexus4. They sell different colors as well. What I like is the keys are protected by the silicone as well and it has nice opening for the cam. I have the original shield on for now, works well. I have the cell for 7 days only. Will apply the
ArmorSuit MilitaryShield ASAP as the original will go broke. This shield suppose to be little smaller and therefore the edges of the case shouldn't pull off the side of the shield as fast.
