It might have been hidden inside a thick plastic case and locked inside a plastic cube, but at MWC 2019 OnePlus showed a prototype of its first 5G phone to the public for the first time. The device was connected to a local 5G base station with an mmWave connection, the variant of 5G that focuses on high data throughput at the expense of range. In the last few days the company has recently confirmed via a Finnish carrier that it expects to launch it in the second quarter of this year.

Aside from showing off what was happening on the device’s screen, OnePlus wasn’t sharing too many new details about the handset, other than to say it was an entirely new device rather than an upgrade to an existing phone. However, the company said that the device could hit a maximum speed of 500 Mbps, although the demonstration content (a 60fps HD stream) was only using around 15 Mbps. It also seemed as though the device’s screen didn’t have a notch, although this could have been hidden for the puposes of this demonstration.
