The Nokia Lumia 520 was the fifth Windows phone 8 handset from the Finnish firm and its slots into the very bottom end of the range just below the Lumia 620. The specs of 520 and 620 are quiet similar, meaning that Nokias main completion at the bottom end of the market is itself. It has a 1.2 gigahertz processor. The few problems that I have faced with my own lumia520 are as follows:
The Bluetooth does not work properly
Windows Store doesnt have those cool Playstore apps and games which is quiet frustrating.
There is no front camera. Hence video calling cannot be done.
Battery backup is very less. I had to keep my phone to charging while doing FB and stuffs.
It used to hang once or twice in every two days.
Although a phone which is under budget this phone is not at all good and trystworthy
