I bought Nokia Lumia 520 3 years ago and it is one of the best windows phone of Nokia. Camera is not best, but it good for those need smartphone for long time. I enjoyed a lot. Battery was awesome. This phone is still working, unlike chinese phones being worst in only 1 year. Never hangs, No problem, less functionality.Very good for simple guys. Style and design is better than samsung phones. The cost is very good and effective
