i have a Samsung galaxy 6 Edge 32Gig, I don't need anything larger. Also a galaxy Tab S 10.5inch 16gig Got them in a combo pack deal with my phone provider. The tablet was 4 bucks more a month.
I think its great, only flaw it has is one speaker on the bottom of the phone. Samsung uses android where Iphone has iOS, personally i don't like iOS. I had a iPhone 4 and i have a Ipad2. Although good devices i hate the fact the operating systems baby people and have f#@k all room for altering. Unless you jailbreak your phone which ends up giving you all sorts of other problems.
My Samsung has its own front-end which i prefer and I've fully customized it to my liking. Also has a fair few cool little features like in coming call colours, constant edge display for time etc, infra red lens (which my htc one had and i use a lot) Big screen, great resolution. Personally i don't see the point of extremely high res on a phone but yay bonus. The camera is great too. Does pretty good pics and has some cool features.
Also prefer the fact that i can download music straight to my phone without the need to have some bullshit itunes crap to do it. Either online or direct copy from my pc. The phone will automatically detect and add the songs to my listings.
