I opted for the S6 as it didn't have the memory card. My S2 used to randomly unmount the card causing me to have to reboot the phone. My roommate has the S5, and she loves it. I'm leasing the S6 from Sprint with an absolutely everything plan. I have the phone encased in an Otterbox. Sprint wanted me to protect the lease, so Otterbox was it! The case makes the phone heavy, but I like that.
