I've only had the HTC Vivid for a few weeks, and I cannot find a way to turn off the notification noise for incoming e-mails and texts. When I go to the settings menu, it just has an option to change which sound. (To clarify; it's not a problem in silent mode, just in normal mode.) It's really annoying to have the sound/light go off at 3 a.m. even if it's just a little ping. Is there a way to turn off sounds in normal mode so I don't have to turn it on silent mode every night?
