So I've had my GS4 for a week now, and I'm loving it so far. I just switched from a Moto RAZR M, which I've read that Motorola doesn't add too much to stock android, so this may be part of my issue: I don't like the phone app. I know how to change the dialer, but once I hit send it goes into the stock phone app. Is there a way to change this without rooting?
