I believe that this has only occurred with the most recent update - every time I receive a text my phone now endlessly repeats the notification noise until I read it. It's annoying enough that I might just switch to GO SMS. There is a (new?) 'Repeat notification ringtone' option in message settings, but this doesn't seem to control the repetition I'm experiencing. Does anybody have a fix? Edit: Meant to post this to bugs, apologies - would appreciate if a mod could move it.
