According to CNET, the Lumia 720 can be guised to a 920 with simple yet high-tech hardware insertions. Nokia is currently working on superior tech products to compete with Chinese gadget market, according to CNET since Nokia faced hurdles to step into the Lumia Windows Phone devices, it aims to focus on traditional methods in the cell phone segment.
