The iPhone X, Essential Phone and now the Huawei P20 and P20 Pro all carry a screen notch, a cut-out on the phone's face where the front-facing camera and other sensors live. The notch visibly leaps out of what is otherwise an all-screen phone face.

Critics feared that the notch would disrupt the all-screen aesthetics, or that it would take a chunk out of full-screen movies and apps. (We've found that it rarely gets in the way on the iPhone X.) Meanwhile, many ding any Android phone that has one as "an iPhone X clone."
