Huawei is on the verge of launching the P50 series, although it remains to be seen in what capacity. Various dummy handsets have confirmed some earlier rumours about the upcoming flagship series, including its camera design and that it will run HarmonyOS rather than EMUI.

I still maintain that the Mate 20 series has the best camera design out of all Huawei flagships released to date. That 2x2 array design without a large circle outside it looks so elegant.
