The images suggest subtle changes to the OmniBalance design implemented by Sony in its high-end Xperia Z devices over the last few years.
The latest live images of the Xperia Z4 line up with what we've seen in previous leaks. The front of the device features a camera sensor on the left (whereas the Xperia Z3 had it on the right) along with slits at the top and bottom for stereo speakers.
The back has the camera sensor — rumored to be a 20.7MP unit — at the top left corner. A noticeable difference with the Xperia Z4 is the micro-USB charging port, which does not appear to be covered by a flap this time around even though the phone is expected to offer protection against ingress of water and dust.
Alleged specs of the handset include a 5.2-inch screen size, with Sony rumored to offer the Xperia Z4 in full-HD and QHD editions. Internal hardware is likely to be in the form of a Snapdragon 810 CPU, 3 or 4GB RAM along with a minimum of 32GB internal memory and IP68 certification. Here's what we want to see in Sony's upcoming flagship.
There's no indication at this stage as to when Sony intends to launch the Xperia Z4, but the series of leaks point to an official unveil in the near future.
