Realy this phone is tough to use and understand the system of windows.
When my friends bought this mobile I cant help him to know about the setting also.
Camera result is even avarage compare to other mobile .
Sound system is not so good.
We cant set wallpaper to mainscereen.
Price is also high compare to other phone like HTC, micromax, lenovo , zenphone, mi,
In same price we can buy mobile of 2-3 GB ram with internal memory 16-32 GB thats main drawbacks of nokia lumia,
