I am using this product form last 3 year and when I purchased this phone it was under Google product and got promise that it will upgrade in marshmallow and they kept their promise. Features is too good it never ever hangs amd run very smoothly cemera quality is so so nice glass quality is hard and it got fallen down many times but never that any stretch in screen happy to have this but after that its price decreased from 18500/- to 13000/- I got so much disappointed and then levono purchase it from Google they gave a update of Naugat multiscreen feature is helpful but msg sending features having bug
