I am an cell freak, normally I try to use almost every popular phone and discover new features in them. recently I had used Lumia 640 and I didn’t find anything new in this phone. this phone has the same features as the old Lumia phones has. the user interface is not user friendly at all. camera quality is slightly better but it didnot make any difference. if you use Internet for more than 20 mins this phone starts heating up which makes you uncomfortable for using it. battery life is also poor. I ended up with gifting this cell phone to one of relatives as it was not useful for me.
