DesignLumia 820 has been a little less luxurious in quality than 920 but still it hasn’t lost its lusture of being a robust phone. The screen is flat with swappable covers available in different colors.
These covers has been named as “shells” by Nokia. They are built of tough plastic materials, can be swapped easily and fit perfectly against rear sides of phone. For now the covers seem to be expensive but the prices are expected to drop over time.
Nokia presents vibrant ad lively colors for back cover including purple, blue, grey, black, white, yellow and red. This gives an option to make your phone look new every time or swap the cover if it has got scratches.
SoftwareThe Lumia series again runs on Windows platform , with latest version of Windows Phone. The scroll-able homescreen with colorful tiles, 3D effects and transitions makes it a fun phone to use.
My favourite feature of Windows phone is People Hub which pulls all the contacts from all my linked accounts Facebook, Twitter, email , phone book etc. to one place. This gives the ease to not just look at contact’s phone number but also his feeds and updates. You can also see their various posts on different social networks under the 'What's New' tab
Nokia appsNokia Lumia comes bundled with some new apps which are hard to find in existing Windows phone. Pre-installed apps include Nokia Drive, which offers turn-by-turn, voice-guided navigation -- something not included in the standard Windows Phone maps app (which is actually powered by Nokia's maps).
Processor, Performance & Battery lifeIt's got a dual-core Snapdragon processor that runs at 1.5GHz and is paired with 1GB of RAM. There's 8GB of storage space built in, but the phone also has a microSD card slot that can accept cards of up to 64GB in size. On performing Browser tests the processor was pretty quick and completed SunSpider in just 916.2ms.
I had no problem with signal strength or call quality during my time with the phone with an excellent call quality due to perfect earpiece and mic quality.
ScreenThe OLED technology has made screen very bright. The colors are very crisp and clear with blacks being blacker. The touch is pretty amazing and can be operated even with gloves on while setting sensitivity to maximum.
CameraAlthough 820 does not contain the PureView camera technology found on the higher-end 920, but its camera is still very impressive. The 8-megapixel sensor, Carl Zeiss optics and dual-LED flash to help out in low-light conditions makes it’s a pretty decent camera to use. A 1.3 megapixel front facing camera is also present for video calling usage
