Could be the rumored C6603 Yuga handset.
A 6.44-inch smartphone screen created by Japanese technology conglomerate Sony has appeared online.
Chinese forum Digi-wo believes the screen is a component for a rumored 6.44-inch, 1080p Sony phablet. The bezels on the side appear to be slightly skinnier than those found on the 6.1-inch Huawei Ascend Mate, which is currently the device with the world's largest phone screen.
Last year, a Sony C6603 Yuga smartphone surfaced, with a photo sample suggesting the device sports a 6-inch screen. Accompanying that is rumored to be a 13-megapixel Exmor RS camera.
Sony is currently preparing to ship its Xperia Z smartphone, with the firm also confirmed to be working on a tablet counterpart.
