on my droid x whenever the phone vibrates either when im clicking something, getting a text or a incoming call. the phone makes a buzz noise. also i noticed the phone does not vibrate as heavy as it should and is not as noticable when its in your pocket with the sound off. i used a droid 1 and a droid incredible in the past and both of those the vibration was quieter. so im wondering are everyones droid x like this or does mine just have a defective vibration mechanism or something?
