I have my T650 set for Vibrate when it's switched on silent, and when it's not it's set for Vibrate and Ring.

For some reason, recently my T650 stopped ringing when switched on "not-mute", however it still vibrates. The only software I've added in the last few months is Volume Care (actually, I only activated it recently, but I've had it for a while).

Has anyone else experienced this? Perhaps someone can give me a push in the right direction?

I'd like to try to avoid a hard reset, but will do so if necessary.

Thanks in advance!
