Also I am therefore pushed almost by chance across this gem after I wanted a high-end smartphone with style and the Internet have scoured - for iPhone, Nokia Lumia 900 and most recently Huawei P6 (the most beautiful Android phone!).
First of all: the Z10 is one of the best and wertigsten phones that there are. The OS 10.2.1 runs elegant liquid, can be operated intuitively and conceptually more elaborate than iOS or Android. There may be more, and also looks better than Apple's iOS. You can tell that the OS here comes from the same manufacturer as the phone itself. Similarly, it's Apple. Android can there by the many adaptations to hundreds of different devices with missing updates then not keep up.
The BlackBerry OS acts mature and extremely consistent.
And since version 10.2.1, which will be released at the moment, you can now - if you want - Android Apps install natively on the Z10. Simply APKs on a Micro-SD and then via File Manager install --PERFEKT!
