We're expecting the Huawei P20 Pro will be announced on March 27 alongside the standard Huawei P20, but you don't even have to wait until then for full details about the phone, as the specs have seemingly just leaked in full.

WinFuture has revealed information on almost every aspect of the handset, including the camera, which apparently has a 40MP main sensor, an 8MP telephoto sensor, and a 20MP sensor that's believed to capture monochrome images and create depth effects.
