While the Xperia 10 series is 5 months old by this writing, Sony is reportedly working on an Xperia 20. Like the Xperia 10, the Xperia 20 has a 6-inch 21:9 display with Full HD+ resolution. Unlike Xperia 10, the Xperia 20 has a better set of internals with a Snapdragon 710 processor paired with 4GB/6GB RAM and 64GB/128GB internal storage.
The Xperia 20 will have a dual rear camera setup comprising of two 12-megapixel snappers. We presume that one of the cameras is a telephoto lens with a 2x optical zoom. As for availability, the Xperia 20 will be exclusive to Japan, and there’s no word if it will be made available globally.
