I have bought Apple 6 plus 64 gb last year, as I am into business class, I got too much good experience to do business with this phone, I can excess too many mails on same time, so I can manage my multiple business.Iphone is the only phone which never hangs.
Even with heavy usage.An iPhone is an iphone and no other phone be it any company can beat an iphone. Finally my phone is working properly &create voice communication in out going or incoming call. I am totally satisfied from the same.
