FLAG_IGNORE_CHEEK_PRESSES constant
int
const FLAG_IGNORE_CHEEK_PRESSES
Window flag: intended for windows that will often be used when the user is holding the screen against their face, it will aggressively filter the event stream to prevent unintended presses in this situation that may not be desired for a particular window, when such an event stream is detected, the application will receive a CANCEL motion event to indicate this so applications can handle this accordingly by taking no action on the event until the finger is released.
Implementation
static const int FLAG_IGNORE_CHEEK_PRESSES = 0x00008000;
