The Apple iPhone X was not the first phone to sport a notch. That honor belongs to the Essential Phone. However, the iPhone was the first of the "mainstream" smartphone brands to feature the notch, and is the phone most associated with it. Because of the edge-to-edge screen and the resulting bezel shrinkage, the notch contains the cameras and sensors for FaceTime and FaceID.
Business Insider says that a lawsuit was filed today in the Northern District of California by one Courtney Davis. It seems that Ms. Davis feels that she was misled by some of the marketing images used by Apple to promote its iPhone XS and iPhone XS Max handsets. She thought that by looking at these images, the iPhone XS she ordered did not come with a notch. Part of the filing shows how hard it is to see the notch with a black background, although we should add that even on Apple's website the notch doesn't exactly jump out at you.
The suit seeks class action status and damages from Apple. There are some other claims involved, including one that alleges Apple overstated the pixel count on the screen because of the rounded corners.
