Nokia lumia 520 was launched more than a couple of years ago and do note that old phones always lack in technology and features if you compare them with current range of smartphones. Lumia 520 is not an exception since when it was launched it was the best value for money device but now it is irrelevant to spend on a phone that has 1GHz dual core processor and 512MB RAM. It couldn’t handle heavy games or the new Windows 10 OS for mobiles easily. Also the camera is average without flash and also it doesn’t have any front camera. The device is single Sim without 4g. So I don’t find any reason to recommend this in today’s date.
