Yesterday my phone suddenly stopped vibrating when I receive a text message. I have my phone settings on "vibrate when in silent mode" (which it is in silent mode) and the text message settings in vibrate. When I check "vibrate" in the messaging settings, the phone vibrates, but not when I am actually receiving a text message. I use no apps for text messaging other than the one installed on the phone. Is anyone else having this problem? I have turned the phone off and took the battery out for about 5 minutes, restarted and still nothing!
