Mobile World Congress is coming up quickly, and the latest leak is a device that might be a prototype for Sony’s Xperia XZ2 Compact, via Xperia Blog.

The photo comes from a commenter on Xperia Blog, who claims that the image shows Sony’s existing Xperia X5 compact next to the upcoming X2 Compact. The device is said to have a 3.5mm headphone jack and a rear fingerprint scanner, which Sony finally began including on its devices in the US earlier this year.

Little else is known about the device, aside from the fact that it appears to have a more curved design than previous phones, but we’ll presumably find out more come MWC.

Sony is rumored to have several phones lined up for MWC, including a full-size Xperia XZ2 (a follow-up to the Xperia XZ), the Xperia XZ Pro (to succeed the Xperia XZ Premium), and now the Xperia XZ2 Compact. The company also released a mysterious teaser for Mobile World Congress yesterday, although it’s unclear if it’s related to the leaked prototype.
