You mention that you like BB10 more. Was the Priv your first Android based phone?
As I compose this reply the 3rd time!!!!!!!!!!!
The Priv is my first Android phone. I have the Samsung Tab S but mainly use it on vacations and some couch surfing. I am not found of Home buttons, back buttons or Recent buttons. The BB10 swiping gestures are smooth and fluid and feel natural. Active frames allow me to know what is multitasking/running. I can assuredly close apps by tapping a little X. I can easily page between apps.
The full Hub is dynamic and everything is neatly in one place.
There was wifi-sharing where the internal and sdcard were available to Win Explorer and I could drag/drop/copy/move/delete files without a usb cable and not have to rely on a funky web browser interface to explore files.
Also the entire phone OS is more secure, I guess. No array of 3rd party apps and developers demanding access to location, contacts, calendar, files, etc. Less of the pervasive Google world in association with those apps.
But obviously, the app situation if you wanted more was sorely lacking.
I get use to the Priv but still really do miss the Z30 experience.
