Constantly tapping the screen to stay awake... Or constantly putting it out of ur pocket... Or no where to place the phone cause you need two hands to fix something as your looking at the manual.
This sits on your face... Where you'd probably be wearing work glasses anyway... And your hands are free to actual do the maintenance while the manual is easy to view.
