OnePlus is set to unveil HydrogenOS, an Android ROM for its non-global smartphone, later this month in Beijing. Now, it looks like the company could also have some new hardware to announce at the May 28 event.

A handful of leaked photos obtained by MyDrivers shows what appears to be a slim metallic rectangle with OnePlus branding. It’s unclear if this is the product itself or simply a fancy box hiding something inside. One popular guess is a OnePlus router, though there’s little evidence to back it up.

We’d love to see the company unveil its highly anticipated OnePlus 2 this month, but that seems unlikely. The Chinese phone-maker was asking fans for feedback on different hardware components earlier this month, suggesting the device is still very much a work in progress.

It’s also possible the entire thing could be Photoshopped, or just a random OnePlus box with nothing important inside. Hopefully we’ll learn more on May 28, though it’s probably too soon to get excited about a new gadget from OnePlus. We’ll also be on the lookout for any more news about this mystery rectangle, so check back soon for the latest news and rumors.
