Once in a month. The Navigation App locked it up; the phone was stuck on a picture of the destination that was displayed when I got there.
Also had to cycle power twice. Once when after listening to Mediafly the loudspeaker would not work, and once I lost the ability to make phone calls altogether (not sure how that happened).
