I'm using Smart Actions and Calendar, both of which came with my phone. I've created a rule with Smart Actions that turns my ringer off while I'm at work, but the problem is that it also prevents my Calendar from properly reminding me about events, i.e. the phone does not vibrate for events like I tell it to. If I turn off the Smart Actions rule, then Calendar reminds me like it should. This happens regardless of whether I set my Smart Action rule to just Vibrate, or just Silent, or both. Does anyone know if there is just something about that app that interferes with Calendar's alerts? Because I guess the solution for me will be to just turn my ringer on/off manually rather than having Smart Actions do it for me, which is a shame because Smart Actions seems like a very useful app.
