This year's Mobile World Congress has been rich in 5G ads, from the Samsung Galaxy S10 5G to the LG V50 5G ThinQ. It has been months since we hear about a 5G phone from OnePlus, and the company finally showed the device at the Mobile World Congress – somehow.

OnePlus had a prototype of its 5G phone in the MWC's showroom, but it was wrapped in a big white box, hiding everything except the screen. In its current form, the device looks more like a bar of soap than a phone connected to the 5G.

In parallel with the demonstration, OnePlus CEO Pete Lau posted a message on the company's forums about the phone development process. OnePlus has been working with Qualcomm on the project since 2017, and the company has successfully sent a tweet over 5G last year. There is no public release date for the device yet.
