It is a good mobile
Lumia 520 its a good choise, it have they good and bad thing, for example, the battery life its too short and delicate, I had to change it twice in 1 year, the screen its a little bit delicate, I fixed my screen and 1 mont later, my phone crashed in the ground, nothing serious, it falls from a short chair, but the touch never worked again:’c
The good thing its the software, its easy to use and very convenient. In general, its a good Phone if you dont need too much in a phone.
