I am allowed to have my phone on me at work, but have to mute it when I am there. I have noticed lately that the only way to do mute all is to press the volume button down, then click on the little cog shaped icon and move the sliders for media, notifications and system all the way down. Is this a problem others are having or is it just me? My Note 2 is less than a year old and this, so far, is the only problem I have had with it. BTW I love this forum. I read it daily, and get some great advice. This is just the first time I needed to ask a question.
