An alleged live image of the expected Sony Xperia 1 IV smartphone has turned up on Chinese social media.

The one in the teaser was the Xperia 1 not new phone looking at the side angle you'll see the centered camera and layout and the buttons are same as the Xperia 1. Saw it on Reddit and they pointed it out.
