My Kyocera DuraXV constantly quits working right.I have gone back to the Verizon store 3 times, done master reset, had to re-enter my calendar 3 times, and the problems persists. The key press tones quit working, The calendar reminders quit working. The software in this phone is buggy as all get out. I just can't depend on this phone. I have had this phone for less than a year. What do I do next? When I was on sprint I had a Kyocera DuraMax that worked great, and was easy to use. The Verizon version stinks.
