Seems like there are a relatively large number of competitors to Apple and Google. Eg. Samsung, Motorola, Lenovo, OnePlus, LG, HTC etc. Not to mention Asian brands.
Duopoly might apply if those companies were using their combined dominance to collude and push other competitors out but that isn't really happening as evidenced by the amount of competitors that are in the market.
