The presence of notches or bangs on the screen will still be a trend in subsequent smartphones, not only because of the need for advanced engineering to reach a smartphone with the entire front in the form of a screen, but also because of marketing problems.
Right now, smartphone design trends are dominated by two brands which are also in the market at the top.

Eliminate this part of the chin because AMOLED screen technology can already be made thin on plastic material, can be curved to the back, and place the screen controller on the back of the screen, not under the screen again.
This method besides having to use an AMOLED type screen that is more expensive than an ordinary LCD screen, also means having to "throw" a portion of the display to be curved to the back, a way that now seems difficult for other smartphone vendors to follow, because besides requiring advanced engineering, it also additional costs must be taken into account from the longer screen

Although in the form of notch design there are pros and cons, in fact this notch is one step towards a smartphone that has a whole screen, as many people would expect.
Besides being optimal in maximizing screen size and overall smartphone body that remains compact, a smartphone with a large screen to body ratio looks more futuristic. Need to design the placement of parts inside a smartphone that is more compact and good so that the remaining space can be used for the screen.

It is inevitable, although the presence of this bangs notch reaps the pros and cons, but this design is now widely imitated Android smartphone.
Some put the need for notch according to its function, others made it only as a design copy.
Make a smaller notch and place the ear speaker as well as the stereo speaker and front camera there, but still have a chin bezel where the fingerprint sensor is still in the dataset.

In terms of technology and design, notch placement is one of the best, because Apple managed to also remove the bezel on the chin.
While these other brands that provide bangs or notch, tend to still have the thickness of the bezel on the bottom or chin.
Bezel on the chin is needed, aside from being used to place navigation buttons like home, recent apps, and back, which have now been moved to many screens, as well as being used as a place for finger biometric sensors or fingerprint sensors. When the fingerprint sensor can be moved to the back or other places such as under the screen, the existence of the chin is still needed, because it becomes a place for the screen driver or screen controller.
