Hello friends I am writing this review regarding Nokia Lumia 730 Smartphone which has latest version of Windows operating system. The phone looks are very good and elegant and also it is very sleek with good screen resolution and good battery like but when I open any applications the application crashes or its not working properly on windows. I tried many applications and installed them many times but no use. Every time I tried to run those they gets hang and crashes. This is the reason why Nokia failed in market because of unstable operating system like Windows. I feel that better to go with Android abd not to waste money on windows phones. jai Hind.
