Lollipop
I think the problem is self-explanatory..
This is highly misleading as it’s up to the individual device manufacturers and the carriers to roll out Lollipop to the devices. Verizon is generally behind the other carriers because of their acceptance procedures and Samsung has only recently made it available on the S5 and Note 4. I have no skin in the game since I have both an Iphone 6 Plus and Android and Microsoft devices and they all have strengths and weaknesses but adoption rates really don’t mean very much and all Apple users are waiting for IOS 8.3 anyway which is in beta at the moment
