My EVO phone in the last 2 days no longer vibrates when i receive exchange emails or gmails! It still vibrates when i get text messages and when i get phone calls...but my emails are now vibration-free, even though the settings for both email accounts are set to vibrate. ANy helpful advice from the wisdom here in the forum?? Is the problem with my actual phone? Should I try and call Sprint to troubleshoot? I've taken the battery out, turned phone on/off, etc., but no help! Answers please!! Help!
