The Lumia 1020 had seen record sales post release and its main highlight has always been the 41 MP PureView rear camera. The add-ons too must not be forgotten– specifically the optical image stabilization and f/2.2 aperture. The 4.5-incher screen might appear dwarfish now but let us not forget that the handset was released a couple of years back. However, the 720p screen resolution gives great scope for image viewing and the angle views too are perfect. The Qualcomm Snapdragon processor offers much meat and especially with 2 GB RAM, multitasking is a breeze. Onboard storage of 32 GB takes care of all your music and movie needs. Decent selfies and video calls are warranted with 1.2 MP front camera. In case you get the air update message for the Denim, ensure that you are on WiFi and that your cell battery is at least on the 50% mark.
