Abstract
A method for key press registration in an electronic device uses a first key press debounce limit (233) if a first housing of the electronic device has not moved relative to a second housing of the electronic device and a second key press debounce limit (236) if the first housing has moved relative to the second housing. In one implementation, the second debounce limit is at least twice the first debounce limit. By using different debounce limits based on whether housing movement has recently been detected, the electronic device reduces the effect of an inadvertent key press made while opening or closing the electronic device.
