I currently have an S4. I love it, I also got an extended battery, and a 64GB MicroSD card. I was hoping a better S5 when the S6 came out but it actually seems like they kinda went backwards on a few things. This has left me thinking about just going to a different phone. What does anyone else think? I know extended batteries are on the way out I have given up on that for a next gen phone but was hoping that the S6 would keep the Water proof, USB 3, Removable Battery and MicroSD card. I can only wonder why they took away these features.
