Don't buy it, Here it is , Why ?. Review on Nokia Lumia 520

I purchased this lumia phone in february 2014 at 10K. For almost 1 year the phone worked perfectly no lagging no stucking with good average camera at that price. But after some few updates it became slow. When I used to start a game it loads fully then suddenly the game is closed, and the phone shows the home screen. As NOKIA was the big company but it didn't worked with microsoft and lack of many apps pulled him down. It couldn't compete big rivelry with APPLE, SAMSANG, SONY, etc. At this price camera was really good with good details, but I don't use this phone, now. After I updated it to windows 10 the phone was literally dead. If this update was not compatible to lumia 520, then why the hell they released for this phone. I advice you not to buy this phone, instead go for android phone.And the last thing, battery was pretty decent, it wil last for 14 to 16 hrs.
