We can't wait to see the OnePlus 9 when it's unveiled in March or April, but it looks like someone already got their hands on a first prototype and actually tried to sell it on eBay. As Android Central reports, the listing has since been removed, but the seller was asking $3,000 (about $2,240 / AU$3,950) for the phone. We don't expect the OnePlus 9 to be that expensive when it appears. According to the listing, this is the same prototype that we've already seen leaked photos of, complete with the special logo on the back that OnePlus uses for its prototypes. A 6.6-inch screen, 8GB of RAM, 128GB of storage and a 48MP main camera are mentioned. We've heard some of these specs before, from the same source: it seems like the prototype that escaped OnePlus' clutches gives us a pretty good idea of what to expect from the next flagship phone in this series.
