I've emailed high-rank employees of Nokia (those who directly know Stephen Elop) and the reason they will never go Android is that the hardware is always changing, and no matter how many cores or how many gigs of ram you have, you will have this thing non-existent on Windows Phone. I heard its called "Lag". I've a friend who has a Galaxy S4 Octa and he installed like 40 apps and when he swipes to the left, it reacts like 2 seconds later and when he was browsing androidcentral for about 10 minutes, his battery percentage dropped by 30%. App support for Android is limited. Android has viruses. Android has no security. Android's apps are not checked. MANY fake apps. The list just goes. OSes like iOS don't have that and runs smooth as silk. Windows Phone is a second.
