Hi all, I am hoping that you may be able to help me with a problem my hubby is having with his phone. Whenever he gets an SMS, the tone that he chose (signal) comes on and then a ringtone (serenity) play directly afterwards. We have checked every possible setting that we can think of to try and just get the "signal" tone to play but that ringtone is still there and is VERY annoying as it goes on...and on... and on. He has had to keep the notifications on vibrate due to this and is missing texts. Any idea of how to fix this problem???? Thanks!
