To further placate customers that opt-in for the handset, as well as to make up for the glaring lack of Android 4.0, elements of that more advanced system have been incorporated into the Ion: a screenshot shortcut (visible on the power menu) and audio controls on its lockscreen (accessible by swiping the time display to the left).
Around back, just to the right of the LCD, is a thumb rest and adjacent video record button, followed by Canon's standard lineup of menu, playback, info and dial controls.
