I am buy Nokia Lumia during 2012 and I yet using this phone. This is a window phone with only 512 mb Ram. This was nice phone that time but today I don’t suggest Nokia Lumia 520 to anyone because I buy it Rs. 10000/- and presently there is various qualities or companies mobile available in the market which have many many more features than Nokia 520. Today various 4g mobile available in the market in lowest price. Nokia Lumia 520 is not a bad phone but in the market this is not up to the mark. Battery backup is also not so good. Looking is simple. customer cares facility is very good.
