The Nokia Lumia 1820 is said to feature a full metal unibody build. A tipster suggests the alleged Lumia 1820 would feature a Lytro-style camera, which will allow users to refocus images even after they are clicked. Other rumoured specifications for the handset include a Qualcomm Snapdragon 805 processor paired with 3GB of RAM, and 5.2-inch screen sporting a 2K pixel resolution. The handset is expected to be backed by a 3400mAh battery alongside a 32GB expandable storage.

On the other hand, the proposed Nokia Lumia 1525 will share the same screen size as Lumia 1520, but will apparently share the same specifications as the Lumia 1820. It is said to feature a 6-inch 2K display, and get a revamped rear camera with either 25 or 30-megapixel sensor, according to @NextLeaks. Rather incredibly, the Lumia 1525 is also expected to sport a battery that can be powered via a solar charging display, something we'll definitely have to see to believe.
