i was having problems with my razr maxx randomly speaking. it would be sitting on the desk and all of the sudden you'd hear navigation lost, or navigation connected and something else i could not make out. Tried factory reset, and did not fix it. i called tech support Thursday and they said they were going to send me a replacement since it's still under warranty. They sent it over night at no charge, and when i opened the box Friday there was a droid DNA, not a maxx. i called tech support, and somehow or another they messed up and sent the wrong device. The tech support agent said if i wanted i could keep it in place of the maxx. it saved me from upgrading and losing my unlimited data. So far I have to say I am very pleased with it. The only thing that I miss from the maxx is the removable memory, as the DNA does not take an SD.
