Nokia has accelerated the application for network access of new Lumia devices around the world. Just a few days ago, Lumia 720 officially passed the FCC certification. Today, the RM-915 Lumia 520 also passed the certification application. Unlike the RM-914 that was applied for last time, the 915 is mainly for North America, South America and Australia, while the RM-914 is mainly for Europe and Asia.

In terms of configuration, Lumia 520 adopts 4-inch LCD touch screen, WVGA resolution, 1Ghz dual core CPU, 512MB memory, 8GB storage space, and 500w pixel main camera. Supports microSD card slots.
