Based on OnePlus' own announcement, it sounds like MWC attendees will be given the opportunity to test the phone's gaming performance in person if they stop by the company's booth.
If you have the privilege of being able to attend the 2019 Mobile World Congress (MWC), you'll also have the chance to try out the full 5G experience with a prototype smartphone from OnePlus. And today the brand has confirmed that the two are directly related. Since OnePlus is teasing the gaming experience, we assume that this smartphone will have quite some power to impress the audience, perhaps, OnePlus next flagship will come with a certain focus in the gaming industry. Firstly, it will most likely be fueled by the Snapdragon 855, with the added benefit being that the SoC will be embedded with the Snapdragon X50 5G modem. A design language that will be pretty similar to the one adopted by Xiaomi with the Mi Mix 3.
OnePlus says that MWC visitors will be invited to "communicate with [their] community over a 5G network", though it's not clear what that entails. The company's CEO has spoken about the 5G revolution and how OnePlus will be launching a 5G-ready handset, which will arrive alongside a non-5G flagship.
