Hauwai nexus 6p is developed under google nexus project. Nexus devices gets the android update first.so if you purchased it than you have to not worry about software department. As google develop new android version you gets new update to your device.
Nexus 6p has veri fast finger print senser. As you tap on senser it unlocks your phone so you dont have to remember password or pattern each time.in camera department it gets 9.7 on 10. Software 10 on 10. Value for money 10 on 10. It has very fast processor and gpu so there no lags at all. I can say it is better than up iphone 6s.
