Issue: After upgrading to version 4.6.0.282 the ring tone volume is very low, even when the profile setting has the tone set to High I often miss the call, I have tried turning on "Audio Boost" with no change, tried a hard re-boot, no change. Volume of calls are fine, it's the ring tones, I have the same ring tone in use as before the O/S upgrade so this hasn't changed, no other (new) apps have been installed, just the O/S upgraded. I can't find any sort of master volume control setting in any of the forums is there such a setting, how do I get the volumes back to normal?
