It is a good budget phone with nice specifications.good look good finishing luncher camera and more configuration.totally it is a big boom in a small package.
Im using Here maps for offline navigation and believe me the gps is spot on without even internet connection just like Nokia Lumia was in the early days. Even in GMaps, while driving I didnt find any issue just make sure that thr internet connection should be good while using GMaps. The only problem in this phone is camera which is okish if youre not a selfie lover. Stock Android is a plus point and Asus promised P and Q update so lets see how it goes.
