Lumia 520 is similar to 525, but 525 is betterthan 520. 520 is the worst lumia phone ever. It will not work any internet functions properly without high speed net( 3G) which loose our money. There is no front cam was the biggest drawback of this phone, poor battery capacity, will made as carry an extra powerbank. It will not support file transfers from any other mobiles direct by bluetooth, I tried a lot and I give up myself. The worst phone ever made by Nokia, There is no value for money.The phone is stylish and got good features, no lagging, running smoothy, but it is not worth .
Please dont buy it, it was the worst experience I ever faced because of this phone
