Sony's purported codenamed S70+ is shaping up to be a monster, with the Xperia Z5+ said to feature a 4K display. This would have Sony being the first smartphone on the market with a 4K display.
The Xperia Z5+ looks pretty much identical to the Xperia Z3+ in the design department, as its design is already pretty slick. We should see it offered in gold and chrome options, with a fingerprint scanner included. Inside, the Xperia Z5+ is powered by the Qualcomm Snapdragon 810, with its 4K resolution splashed onto a 5.5-inch display.
