According to the media reports, the next OS might be called "Android Popsicle". In March, Google released the first developer preview of Android P that was mostly focused on the changes that will affect developers and not on user interface (UI) adjustments.
Google added a built-in support for a notch cutting into the display at the top of the screen, called "display cutout support". The company also tweaked the look for the "Quick Settings" panel and the notification drawer with rounded corners.
