Google has noted that there are now 16 Android devices with screen notches from different manufacturers. Additionally, Google also highlights that in order for cutouts to not intrude or negatively affect apps, two requirements are needed. Apps on Google Play won't be able to support more than two cutouts on the display.
It is already known that Android P will support cutouts of various sizes so that apps are better optimised for any and all notches.
Within these constraints, devices can place cutouts wherever they want. That means no more than two cutouts on a device, and multiple cutouts can't exist on a single edge. There's nothing the company could do to prevent handset manufacturers from making phones with any number of notches they want - but it could make life hard for anyone who made a decision to ignore the guidelines.
As Android P official launch nears, Google has released guidelines for developers updating their apps to support the notch, or as Google calls it, the "display cutout". One of these is a limit on the number of display cutouts; Android P will allow a maximum of two cutouts with only one allowed per side (top or bottom).More news: Facebook identifies campaign to interfere in USA midterm elections

In one of the latest posts on the Android Developer Blog, Google has outlined all the methods to implement the notch for various apps. Apps by default will have to be letterboxed in the landscape mode; although developers can make use of the space around the cutout in landscape mode, with content around the cutout. While we have seen the number of notched Android phones growing increasingly this year, consumers are still divided on the notch.
Notches are either the bane of everyones existence, or just a future part of mobile life, at least until manufacturers work out how to incorporate the relevant sensors underneath the display.
To say the smartphone industry's decision to begin adding "notches" to its flagship smartphones has been a controversial move would be a massive understatement. So far, the most popular solution is a screen cutout.
