It can be upgraded to wp 10. first install windows upgrade advisor and the down load win 10
I am happy with the performance of win 10. performance of F M radio is not good.
I am using Microsoft Lumia 640 Dual Sim for the past 7 months, amazing experience.
Windows 10 update makes it more enhanced.
No performance issues ( I play Modern Combat 5 with no lag and crashes ) .
Best phone for its price.
Since micrsoft took over nokia, it has gone from worse to worst. They need to allow the Nokia team to handle the manufacturing and needs to sparate phone from laptops and computers. I am hard core buyer and users of Nokia but had to let go because of Micrsoft methods. I recall buying Microsoft phone for a friend and to use the phone, you have to have microsoft account and we spent 4 days to be to use a phone. From that day, I tell all that cares, that it is the worst phone to purchase. Nokia was toast of everyone, it can be used by woman in African/Asian villages. But microsoft made phone for only educated folks and hence the reason why it is selling.
