Huawei showed off its forthcoming Mate X folding phone-let (or tab-phone) at a media event in Johannesburg today. While we were able to hold the device, we weren’t allowed to fold it, so we had to rope in the help of a Huawei representative for the video below. Nonetheless, we got to check out the camera setup and try various apps, and our early impressions suggest it’s going to be a highly desirable — and crazy expensive — when it arrives in June or July of this year.
