The Nokia Lumia 820 is a stylish, mid-range smartphone that delivers high-end performance in a compact package. The Nokia Lumia 820 has the same unibody look and feel as the high end Lumia smartphones, and comes with an exchangeable shell design that offers wireless charging capabilities and is available in a range of colors. Beneath the shell is room to insert a micro SD memory card. It got a 4.3 inch ClearBlack OLED WVGA 800×480, Super Sensitive touch Nokia ClearBlack with high brightness mode and Sunlight Readability Enhancements. A 1.5GHz Dual Core Snapdragon S4, 1GB RAM, 8GB mass memory with microSD memory card support and 7GB free SkyDrive storage. An 8MP Auto Focus with Carl Zeiss optics Dual LED flash
Full HD 1080p video capture at 30fps. the Lumia 820 feels like a larger Lumia 800 with better performances speeds (1GB of ram helps).
The back cover does come off easily and I do like the options for a rechargeable back cover as will as a soft shell back cover. Over the device felt comfortable and easy to use. We have to wait and see when we get some good hands-on time with the device
