The only think-different that I can see in the Galaxy S6 line up is the S6 Edge. That’s something interesting and people would want to get their hands on it and hopefully buy after testing it out.

The rest is probably industrial copy; to be specific copying what Apple has done, like thumb print scanner, metal or aluminium or anybody. The thumb print scanner even has a thumb print, animation just like Touch ID.

The departure of removable battery and the SD card slot may put Samsung in big trouble. Die hard fans of Samsung Galaxy will probably make lots of noise and start going to other smart phone maker that provide SD card slot and removable battery.
