Sony Xperia XZ3 leaked press render shows off traditional display, glass-metal combo build
We're also seeing that there's a fingerprint sensor on the back of the phone, along with a very small flash and another sensor that could represent part of Sony's Hybrid focusing technology. Also, the phone does seem to feature a full-front glass design, while the back of the phone is supposedly made of metal.
As far as the hardware inside the Xperia XZ3, we don't have too many details about the phone, except that it will be equipped with Qualcomm's Snapdragon 845 processor, 6GB RAM, and 128GB internal storage.
Last but not least, the date on the display suggests the phone might be announced on August 30, although Sony hasn't yet confirmed any events for that timeframe yet.
