Abstract
A mobile communication terminal (400) has a controller (410), a touch display (430) and a proximity sensor (420). The touch display has an inactive mode (610; FIG. 5A) essentially without user interaction ability, a lock screen mode (620; FIG. 5B) with limited user interaction ability, and an operational mode (650; FIG. 5C). The lock screen mode generally prevents a user from accessing functionality (560) provided by the mobile communication terminal in the operational mode. The controller is operative, in the lock screen mode, to detect actuation (622) of the mobile communication terminal; identify the detected actuation as a user command; evaluate a sensor reading (422) from the proximity sensor; if the sensor reading from the proximity sensor indicates (632) presence near the mobile communication terminal: prevent execution of the user command, provide user feedback (634) by the touch display and continue in the lock screen mode; and if the sensor reading from the proximity sensor does not indicate (638) presence near the mobile communication terminal: execute the user command (640).
