The Nokia Lumia 520 is a depression-toll, entry level Windows Phone introduced in late Feb 2022 at Mobile Earth Congress. A variant, the Lumia 521, was created for T-Mobile US.

The device features a modest four-inch IPS display (800 x 480), viii GB of internal storage, micro SD expansion, 512 MB of RAM, dual-core i GHz Snapdragon CPU and a 5 MP rear camera. Due to its depression cost, the phone lacks a front facing camera and NFC.

In January 2022, the phone began receiving Windows Phone viii Update 3 and the Lumia Black firmware.

The Lumia 525 was too introduced to express markets, and it features 1 GB of RAM with the same specs as the Lumia 520.

Worldwide, it's the nearly pop Windows Phone. The Lumia 520 is expected to receive Windows Phone viii.1 in mid-2014.
