Keyline and margin
To avoid conflicts with screens that have curved edges or corners, display information and place interactive components with margins of at least 24 dp on both the left and right sides.
Reject zone & Grip zone
To avoid accidental input, One UI blocks touches in the margins. The Reject zone blocks touches in the interaction area. The Grip zone blocks palm touches and three-finger touches that may occur when the user is holding their phone.
Cutout area
Depending on the device, items displayed on the screen should be optimized to avoid the camera cutout.
