I have a razr maxx hd that I keep in vibrate only mode most of the time. I use the slider on the unlock screen. I am having some frustrating problems with vibrate and I?m not sure how to explain them. This occurs for both texts and phone calls. 99% of the time it won?t vibrate when sitting on the table. It will usually vibrate when in my pocket. In my pocket it will vibrate for unknown callers, but often won?t vibrate for stored contacts. If I am having a conversation with my wife it might vibrate the first time, but skip the next two then vibrate on the next. I took it to the Verizon store to ask about it. She called me with her phone and of course it vibrated while sitting on the counter. The worst part is the phone calls. If it?s sitting on the desk I can?t tell there is an incoming phone call because it doesn?t vibrate. All the settings I?ve found are set to vibrate. Is this a bug or is there something I don?t have set right?
