Another picture is available here. We still do not know when will Xperia XZ3 hit the store shelves, but who cares! There are pictures to analyze. Pictures show a most likely 18:9 display with a considerable bezel above. This top bezel is where the speaker and single-lens camera are placed. Power and volume buttons are placed on the right edge of the device. Rear panel, curved and made of glass, houses the dual-lens camera. Overall, the whole thing looks heck of a lot like Sony Xperia XZ2 Premium.
We will let you know when we learn more about this upcoming device.
