Recently an anonymous device with model name–PM 0780 has visited FCC for certification. The device that has now been certified can be alleged Sony Xperia Z4. However the model number is not enough evidence in this case. We have also managed to match dimensions and they are same as those of Xperia Z3 (5.75 x 2.87 inches). The certification also mentions room for expandable storage. It will run on Android 5.0 Lollipop with Sony’s in-house lightweight UI on top.

The rumored specs of the device include 5.1-inch 1080p display. It will run on Qualcomm Snapdragon 810 SoC with 3GB RAM and 32GB storage. Camera-wise it has 20MP rear camera with LED flash, and 5MP front-facing snapper
