Lumia 620 is the third smartphone to carry the Windows Phone 8 operating system. The other two - Lumia 820 and 920 are high-end models, while this one is a more of a mid-range / low-end model.
The closest competitor to this phone is the HTC Windows Phone 8S. Both phones carry a similar spec sheet. Both have a 1GHz dual-core processor, along with 512MB of system memory, a 5 megapixel camera capable of shooting 720p HD videos and a 480x800 pixel resolution screen.
The phone integrates a small 3.8 inch screen, while its competitor carries a slightly larger 4 inch screen. The good part is that the Nokia Lumia 620 comes with 8GB of internal storage space while the HTC WP 8S carries only half that, 4GB. Both phones are pretty similar when it comes to hardware.
