1. A method of measuring drop impact at an electronic device comprising a display having a touch-sensitive overlay, the method comprising:
- when a touch event on the touch-sensitive overlay of the display is detected, applying a force from a piezoelectric sensor to the display to provide tactile feedback;
when a fall is detected based on signals from a drop detection sensor of the electronic devicereceiving an output from the piezoelectric sensor; and
storing drop data, based on the output from the piezoelectric sensor, in a memory at the electronic device.
