HUAWEI is all set to introduce the Mate 30 and Mate 30 Pro smartphones at an event in Germany on September 19th. Today press image of the phones have surfaced, revealing the design, thanks to @evleaks. This reveals quad rear cameras with LEICA VARIO-SUMMILUX-H 1:1.6-2.4/18-80 ASPH lens for the phones. However, there are three cameras on the front for the Mate 30 Pro inside the notch, and the Mate 30 has a smaller notch since it has dual cameras on the front. These phones are expected to retain 3D face unlock and in-display fingerprint sensor from the Mate 20 series.
