Stock Android for first MotoG from motorola, Android Lollipop...
"It's a phone, not a computer" as I like to say, I don't want phones to be able to do what my computer can, if it calls, has instant message like whatsapp(need for work and low cost calls), bank app, and wifi antenae to browse the web a little, then it's fine.
while, I have to admit, I use it for some e-books, prime user 😛
