The latest word is that the Nokia Lumia 1520 V will have a 4.45 inch screen with resolution of 768 x 1280. Original reports had the phone carrying a 1080 x 1920 resolution on a 4.3 inch screen, but that apparently was too good to be true. A 2370mAh battery will be powering the device, which will offer the 3 columns of Live Tiles like the full-sized phablet.
The Nokia Lumia 1520 V (which stands for Viisi) is expected to be launched in April. So far, no pricing information has been leaked.
