Hello
##about android version :
Lollipop 5.1 was released in March 2015, which might be considered “old” if you want the top-ultimate-latest thing. But in the real world, it is still the most used version today :
As of September 2016, Android Lollipop (5.0 – 5.1) is the single most widely used Android version, operating on 35.0% of all Android devices accessing Google Play. The second is Android KitKat (4.4), with a share of 27.7%.
(source Android version history - Wikipedia)
Marshmallow is slowly growing, and Nougat will be officially released in december 2016.
###For the camera :
It is very subjective, but also the FP2 doesnt have the top-ultimate highest end camera. You can make your own opinion there :
About support :
Well, to my own experience, stores are totally USELESS. They are sellers. They don’t know anything about repairing a phone, they will be here to tell you that you need another new phone. That is my personal opinion only. You get better support by asking the community here on the forum. And other brands do not offer such a forum.
