I was wondering if there was an option to raise the amount of vibration in the Nuron (5230). 'Cause when I get a text message or call, it vibrates, but sometimes too softly for me to actually feel anything. And so I wouldn't see it until a few hours later. So is there any way to raise the vibration for calls and messages on silent mode? All I see is an option for ringing volume. Thanks for your time.
