LG so far, save for the notch, has managed to stay away from drilling holes in its smartphones in order to move hardware components from the bezel. However, a recently uncovered patent application, from the Turkish patent office, describes an LG smartphone with a punch hole, as suggested by the drawing below.

It still has a considerable bezel and an even larger chin, but this is just a schematic to illustrate the patent itself, which was granted at the end of April. If LG follows through with the project, we might soon see the first LG smartphone with a punch hole, and, as the schematics reveal, it will retain the triple-camera setup introduced with the LG V40.
