Sony has released a brief teaser for its upcoming appearance at MWC19. The clip has the caption "embrace a new perspective" that seems to point at the expected 21:9 aspect ratios of the Japanese company's new smartphones. Apparently, the devices formerly known as the Xperia XA3 and XA3 Plus will be released as the Xperia 10 and 10 Plus, respectively.
