Apple did not come out with the notch first. https://www.quora.com/How-do-people-keep-forgetting-that-App...
But ever since Apple released the iPhone X, suddenly there are notched phones everywhere. And these phones don't seem to be trying for an edge-to-edge display, so it's curious that they would choose to adopt a notch unless they're just trying to copy Apple. (Which is a viable suggestion since the smartphone market is more or less divided into Apple and Everybody Else.)
