Pretty sure they mentioned welcome to 2012 from hardware specs.
The gs6 is the only phone using 8 cores and 14nm finfet.they are a full year ahead of every one now in hardware.
That is EXACTLY what they meant. The internals of the iPhone have always been shameful compared to even some budget devices on the Android front.
*Battery technology has also CHANGED dramatically. (Also missing in the iPhone). You really don't need a removable, spare battery when you can change the phone in 20 minutes or less.
My nexus 6 can go from dead to 80% in 10 minutes. The Galaxy 6 is using this same tech.
Also.... SD cards are somewhat irrelevant now that phone storage is becoming standardized at 32GB for the entry level models, and ALMOST EVERY OTHER COMPANY EXCEPT APPLE charges $50 or less to double the storage. So for $50 more, get 64 gigs. You don't need an SD....
Please don't confuse evolution in specs with going backwards. Also please do not confuse evolution in tech with taking away a feature.... when it's giving you a brand new feature that is far better.
I also can't really say Samsung copied the iPhone.... many people have posted pics of devices Samsung has had out that make the iPhone 6 look more like Apple lifted their design.... but wait.... at this point, there are only so many ways you can make a phone look. I think the rip off design machine days are over and a moot point. Unless you do some crazy thing like BB with the square phone, most phones look alike.
The only thing the really makes the iPhone stick out from other phones is it's unforgiving large forehead and chin, and the big ass home button, as well as the vomit of color in ios 7/8.
