Sony leaked its own product information about the new Xperia Z4 Tablet ahead of its official release. Sony's Xperia Lounge app showed the new Xperia Z4 Tablet before it was taken down. At least the source should be reliable because it's coming directly from Sony. The news just came a little sooner than Sony would have liked. As for the leaked details about improvements over the previous model, it looks like it will have a 2K display, a faster processor, and longer battery life according to the photos.
