the only annoying thing about the maxx is that the phone screen times out the second I pick up the phone when a call comes in, I have to press the power/screen on button several times before I can put it into speaker mode. I had the thunderbolt and the phone stayed on a few seconds to allow for the user to put the speaker on during a call instead of this ridiculous method, it is horrible when in the car and the phone is not on a Bluetooth.
