I purchase Microsoft windows phone last year for my wife. In starting days it works very smoothly, but after upgrade of windows 10, this phone become useless. In this phone you cannot do multitasking, whenever we start using more than three tasks, phone become hang for long time.
After 10 1to 15 minute when you restart mobile then it will become normal. Battery life is also not so good, we have to charge after three to four hours daily.
Screen is long and camera is ok, you can use in short distances objects. I don’t feel this windows phone is usable in this era because in market so many advance version of android phones are available in same price.
