Abstract
Systems and methods for keeping a display screen active that include a fingerprint sensor coupled to a processing system and configured to perform a check for a presence of a finger. The processing system may be configured to alert an operating system to cause a display screen to be in an active state based on a detection of the finger; perform a future finger sense action to detect that the finger is still interacting with the fingerprint sensor; report to an operating system, based on detecting that the finger is still interacting with the fingerprint sensor, that the display screen should remain in the active state, wherein the operating system causes the display screen to be in the active state based on the report.
