I have been putting togather furniture for years and the instructions on some are terrible. Cams are no problem but when they omitt a step because they think you know it already is a problem.
I have not gone the cell phone way and so I know nothing about them except they are extremly irritating.
Just found out that you have to hold down the button to turn the darn things on. No instructions on that one. They expect you to know that when nothing else requires you to hold down the on button.
