From the pictures, we can tell that once again Sony will resort to using a 20.7MP snapper on the back of the device. And it would appear that the back will once again be made of glass.
The Sony Xperia Z4 is expected to come with a 5.1-inch screen carrying a resolution of 1080 x 1920. That combination results in a pixel density of 432ppi. The 64-bit octa-core 1.9GHz Snapdragon 810 CPU powers the handset as previously noted, and the Adreno 430 GPU will be handling graphics. 3GB of RAM is said to be on board along with 32GB of native storage (of which 23GB is available to the user).
The FCC documentation shows that there will be a microSD slot on the device. We've already covered the camera on the back of the phone and we expect a 5MP snapper on front for selfies and video chat. The Xperia Z4 is IP68 certified which means that it can be submerged to a depth of 4.9 feet for as long as 30 minutes without being damaged. The 3400mAh battery should provide long battery life for the unit, which will have Android 5.0 pre-installed.
It would seem that with each leak, we are getting closer to the unveiling of the Sony's next flagship handset.
