Leaked: Internal Sony Docs Reveal Xperia Z4 Design, Changes And Upgrades
Sony Xperia Z4 Fully Revealed In Sony's Leaked Internal Documents@Onleaks

Sony made headlines last year when a notorious hacker group leaked the company's internal documents, revealing studio's future movie productions, celebrities' phone numbers, their aliases and other confidential information. Interestingly, Sony's 30,000 plus documents had details on the next flagship, the Xperia Z4, which is slated for a September release with major improvements.

It is not the first time that we are hearing about the Xperia Z4 but the fresh details promise more authenticity as it comes directly from the manufacturer's doorstep. Although nothing is confirmed, the renderings shown in the new leak suggest Sony is taking a major step in terms of upgrading its next flagship.

The tipster who put forward the fresh details, @ViziLeaks, claims Sony is going "all metal with the #Z4. Iconic power button getting a refresh too with a built in touch finger print sensor."

According to a Phone Arena report, the leaked photos of the Xperia Z4 suggest that Sony is ditching the traditional glass back for a metal panel. Use of terms like "seamless", "simplicity", and "solid" hint at the company's new design strategy for its next flagship. Sony might take a page from Apple's design book in integrating 2.5D glass that was featured in the iPhone 6 and also bring overhauled MONO/New UI in its Xperia Z4.

It is important to consider that the Sony documents were dated October 2014, which means a lot of changes can be made from what is shown with regards to the Xperia Z4.

Recent leaks have revealed some technical specifications of the Xperia Z4 such as a 5.2-inch screen with Full HD and Quad HD resolutions for different markets, 20.7MP rear snapper with OIS, 5MP front shooter, Qualcomm Snapdragon 810 processor, 3GB/4GB RAM and 32GB onboard storage. It is not clear how far these specs are true, but they are not completely unimaginable considering rivals like Samsung have already laid the foundation for such upgrades.
