I know you guys are thinking about title. But yes this phone works till it is under warranty, I mean it is works good only for one year. I used this phone from 2014 to 2015. I thought It would be great phone as compare to android. But I was wrong. It crashes everytime. Actually it doesn’t have apps like android but the apps this phone has, crashing again and again. This will make you unhappy.
Now talking about processor. It worked good and fast for starting 2 to 3 months, but after that it would be slow. CPU: the worst quality cpu Microsoft has. After one year your phone’s CPU will be damaged, doesn’t matter weather your charging or using it properly.
So I suggest you to please don’t buy windows phone ever.
