Following in the precedent set by Oppo a couple of weeks ago with its F9 Pro handset, Huawei is reportedly going with a small teardrop-shaped notch on its upcoming Huawei Mate 20 smartphone, according to new leaked renders shared on XDA Developers. 

Looking closely, we can see a small speaker sitting just above the front-facing camera nestled within the notch, similar to the layout used by Oppo on the F9 Pro, only perhaps with a little more subtlety.
