According to one aspect, a portable electronic device sized and shaped to be received within a holster having a magnetic element. The portable electronic device includes an electronic compass adapted to measure a magnetic field of the magnetic element in at least two axes. When the measured pattern corresponds to a first pattern, the portable electronic device is adapted to determine that the portable electronic device is in the holster.

A method of controlling an electronic device having a touch-sensitive display includes determining a first value representative of force applied by an actuator to a touch-sensitive input device of an electronic device, controlling the actuator to modulate the force on the touch-sensitive input device for providing tactile feedback, determining a second value representative of force applied by the actuator to the touch-sensitive input device, and adjusting control of the actuator to adjust a subsequent force applied by the actuator based on a difference between the first value and the second value.

A method includes determining first respective values representative of forces applied by a plurality of actuators to a touch-sensitive input device of an electronic device, controlling the actuators to cause the actuators to change the forces applied to the touch-sensitive input device, determining second respective values representative of the forces applied by the actuators to the touch-sensitive input device, and determining when there is a fault based on a change from the first respective values to the second respective values.

A method of controlling an electronic device having a touch-sensitive display includes imparting, by an actuator, a force on the touch-sensitive display to provide tactile feedback, determining the force applied by the actuator on the touch-sensitive display, and adjusting a subsequent force imparted by the actuator based on the determined force.
