In the settings, I chose a notification noise for when I receive a text. This works fine. However, there's a separate "reminder" noise, for when I dont look at the text right away, that does not stop even after I read the text. It's a low "dunk" noise and occurs every few minutes. The only way I can clear it is to restart my phone. Any ideas on a way I can fix this issue? I should mention the icon showing a text msg has arrived (in the top bar of the screen) disappears after I read the text, the only issue is the ongoing tone.
