Guys should i go for Nokia Lumia 520 or Samsung Galaxy S Duos ? Both are same price in my country and am very confused.I currently own a cheap Android phone running Gingerbread and frustrated by its slow performance.I am willing to give WP8 a try due to its nice smooth performance and simplistic and cool UI.I am not too bothered by lack of apps or limited customization as long as the phone fulfills my basic requirements like internet surfing,video watching,light gaming and decent battery life.I do use a few applications like Whatsapp,FB,Opera Mini,What do you suggest ?Please compare both phones and tell me .
