There are currently very few phones running Android 5.0 . Some of the phones currently running Android 4.4 can be upgraded to 5.0 . I don't know know any techno phone that has its preinstalled operating system as android 5.0.
But I know some of their devices can be tweaked to get the lollipop. For example my original android version was 4.2.2 but I tweaked it to 4.4.2 . It's very dangerous though.
