Even though the Huawei Mate 20 Pro will be officially unveiled on October 16, an IFA attendee apparently managed to spot the flagship phone when someone, apparently a Huawei employee, was carrying it around. Even though the images are grainy, one tell-tale sign gave away the identity of the phone.

The folio-style case the device was wrapped in wasn’t enough to protect its identity as a cutout at the back provided a glimpse of three camera sensors and an LED flash aligned in a square pattern. Currently, the Mate 20 Pro is the only smartphone expected to feature such a configuration, but don’t count out the Mate 20 just yet.
