Actually I don't have a Settings->Sounds and notifications->Interrupt mode option any more, following a recent (I believe Samsung devices only) firmware update it's been replaced by the Sound mode option. I still have the Tasker Interrupt mode action of course but that doesn't seem to give me the full Mute option that I am looking for.
What I'm trying to do is get a full mute situation (all volume levels to 0 AND no vibrate action at all). I can't seem to achieve this - when I bring the ringer volume to 0 the phone switches on vibrate automatically and (from Tasker) I can't figure out how to stop this. The 'new' 'Sound mode' Mute option does this very nicely but I think there is no Tasker action that corresponds to it...?
I'll try some further testing with Tasker's Interrupt mode action in case I've missed something.
Thanks.
