  • Answer to: Why iPhone 4 doesn't vibrate?

    The tapping technique worked for only a few seconds, a minute at best until it stopped again. I bought a new vibrate motor and upon opening the phone I found a small piece of tape or ribbon cable next to the eccentric motor weight that had come unstuck and was in the way of the spinning weight, stopping its free rotation. I used a tiny flat head screwdriver to stick it back to the wall and the vibrate function works as good as new now. I just wonder how long before the sticky fails again and can the tape be removed completely? Thanks for all the advice, I can now receive calls on set which is very good thing. Scrumpyalex
