This package does not match the nokia lumia 520, there is a slot for the flash and one for the rear speaker. But the Nokia Lumia 520 has no flash and the loudspeaker is on the other side. So not suitable. Same for movies that do not go on the screen. Only the pen is good. And finally the flap on the stationary part is very inconvenient. It would have been better on the moving part of the phone because it interferes when we call, when navigating and when sending text messages (all the time what)
And relations with the vendor customer service are quite laborious. Everything is resolved but it is very very long. The Amazon service is much faster. I do not recommend if you have a Lumia 520.
