I have had my S4 for about a week I must say that this is the best phone or tablet I have ever owned. Granted, I am coming from a Samsung Galaxy Prevail, but I do own an Asus Infinity and a Nexus 7 so I know what Android can do. I have been running nova launcher, Tasker, juice defender, NFC launcher and multiple widgets with no apparent slow down. I ran the phone for the first few days without doing anything to it and i was surprised at how good the battery life was, but if you install Juice Defender your battery life goes way up. Right now this is the most advanced android device on the market, phone or tablet. Always having a 13 mp camera at hand is awsome, and Samsung has outdone themselves with the included camera software, many, many modes and cool effect. I think I might not even have a need for either of my tablets now. Anyone want to buy an Infinity or Nexus 7.
Ohh, the case that is pictured is a case from tech 21. It is a protective case that uses a non-newtonian fluid to dissapate the force of the impact. Very stylish leather front flap, can be ordered without and in diffrent colors, and it is much smaller than the otterbox, but don't take my word, look up drop test for s4 tech 21 case.
