If only I could... Unfortunately, it's a device for work, and I need to be able to respond to calls and texts from people that are not in my contact list, even outside working hours. I don't have any apps producing alerts other than messaging, calls, email, and calendar, but Monday I got twelve texts from seven different people in less than five minutes. All needed responses within five to ten minutes. I could ditch it, but then I'd have to carry a pager.
