Xiaomi is really milking the unveiling of its first ever drone, with a short teaser video of the device now surfacing online. AndroidCentral spotted the video on Chinese streaming site Youku, and we've embedded a YouTube mirror above. There are no surprises here, though, especially based on what we've seen from Xiaomi's teaser images. It looks like a pretty standard quadcopter, albeit with an underslung spherical camera. Previous leaks suggest this is controlled via an app and records 4K video. We'll know more on the 25th this month, when Xiaomi is scheduled to live stream the drone's unveiling.
