I find it astonishing that the Galaxy S5 had removable battery, could accept an SD card, AND WAS FREAKIN' WATERPROOF. At least extremely water resistant. Oh, and had a headphone jack.
Then what did Samsung do in the Galaxy S6? Not waterproof. No SD card. And non-replacable battery. Why? (And Samsung stated as much . . .) to be more like an iPhone. More metal and glass. (freakin idiots)
Newsflash: if I wanted an iPhone, I would have bought an iPhone. Not that there's anything wrong with that.
In the end, it was the bloatware that made me move away from Samsung. Now I like my Nexus 6P, unlocked, with no bloatware and plenty of storage. All paid for up front. And it's got a screen as big as a Galaxy Note. (Is that a Nexus 6P in your pocket, or are you just excited to see me?)
