The only issue that bothers me is the memory, it's the one reason why i went from the S4 to the S5 and not the S6, because the 5 had expandable memory (to be fair, the lady i spoke to in o2 when i got my contract for the S5 understood why i chose the 5, whereas everywhere else was trying to shove the S6/Edge at me). If the 7 doesn't, then that would be another Samsung flagship phone i wouldn't consider.
Waterproofing is a must as well, can't believe Samsung ditched that with the S6.
