Samsung patents even more notches, each smaller than the other

And this, kids, is how a camera is born
A similar looking notch was recently patented with the USPTO, although without all of its siblings. It’s very unlikely that we’ll see devices with all of these notches, however, Samsung is probably just making sure it has all the bases covered before seeing exactly where the camera will end up on the final design(s) of its future phone(s). The camera is depicted in the patents appears to be in the middle of the display, as is usual, which differs from the renders we’ve seen with a selfie camera hole in the corner. This design might be reserved for Samsung's cheaper smartphones.
The tiny notch and display hole are the two designs we can expect to see over and over again on smartphones from different manufacturers in 2019 before the front-facing camera can finally be hidden under the display altogether, hopefully as early as 2020.
