Hi friends,
As you all know lumia 520 not a Nokia Corporation mobile this mobile lunched by Microsoft company. Lumia 520 have various problem including hardware and software. In hardware RAM and Processor is very cheap Quality so mobile not work in proper way. And Software of lumia 520 also very bad( Browser Input pad etc.) very bad mobile touch is very hard not smooth. so Microsoft Lumia 520 in my review not for value of money.
