I may be totally uninformed but I've got to ask... The iPhone X has a notched display for hardware that runs FaceID, and not for aesthetic reasons right? Why are Android manufactures copying the notch? Strictly because it's a new design element of the iPhone X? I know people do not like the notched displays and if Android phones aren't implementing FaceID alternatives to take up that space, then why do it? Are they just really copying the iPhone design so that their phone looks modern by 2018 standards?
