I came from a Razr Maxx. The phone initially blew me away and I immediately purchased the S4. Overall, I am impressed with the phone. I honestly thought the battery would suck, being used to a Maxx, but i'm satisfied with it. I wish the casing was stronger like the Moto's, but sacrifices have to be made. The one thing that puzzles me is the motion, in our VZ store we had a Samsung rep come in and show his AT&T version of the S4 and the motion was outstanding...I can't get mine to do that at all. Gallery view motion works, that's it I've researched it and still can't figure out why. Ah well, Still a great phone!
