I recently removed the SD card from my phone to copy the files from it as a regular backup. When I returned the SD Card to my phone I noticed that the notification sound that is played when the standard Android 'Mail' application receives an email has changed. I have gone into the Settings > Sounds > Notification Sound menu and confirmed the correct sound but the Mail application continues to play a different sound. The funny thing is that this newly selected sound isn't actually even listed under my options for notification sounds. I have tried the following solutions: deleting the account from Mail and re creating it Restarting the phone Force quitting the Mail application Removing the SD card and return it again Unmounting and Remounting the SD Card I think that I may have to somehow reinstall the Mail application or at worst return to factory settings (something I wish to avoid doing) Any suggestions would be appreciated Thanks!
