Android supports a Display Cutout as described
in the SDK document. The [`DisplayCutout`](
https://developer.android.com/reference/android/view/DisplayCutout) API defines
-an area on the edge of the display that is not functional for displaying
-content.
+an area on the edge of the display that may not be functional for an application
+due to a display cutout or curved display on the edge(s).
If device implementations include display cutout(s), they:
-* [C-1-1] MUST only have cutout(s) on the short edge(s) of the device.
-Conversely, if the device's aspect ratio is 1.0(1:1), they MUST NOT have
-cutout(s).
+* [C-1-5] MUST NOT have cutout(s) if the device's aspect ratio is 1.0(1:1).
* [C-1-2] MUST NOT have more than one cutout per edge.
* [C-1-3] MUST honor the display cutout flags set by the app through the
[`WindowManager.LayoutParams`](
