My blaze started locking up and going to the Fitbit logo after about five miles of walking. It was already struggling to hold a charge for less than a day so I only wore it to walk and not the entire day. I could usually hold the buttons to reset and then do a restart for the next day but then it stopped the other day and will not let me reset or charge. It also gets very hot on the charger without charging. I have cleaned the contacts and used a different charger with no success. My blaze is about two and a half years old.
