Sharp and the Essential Phone, which essentially pioneered the top bezel protrusion we started calling a notch since Apple introduced a giant one in the iPhone X, went about it in a subtle way. Their top thingies only house the selfie camera and are very minimalistic. Apple, however, opened the copycat floodgates and companies like Huawei or LG went to town on their top bezels to achieve the same "all-screen" effect, while others like Samsung or Sony, stuck to their guns.
