I use a Fitbit One to track my steps on a daily bases.  Lately, I have noticed that the number of friends who are still using Fitbit has declined to just 2.  Furthermore, the current installed firmware version 6.64 is a horrible.  It apparently is powering down randomly and doesn’t power back up upon movement.  I can’t seem to get it to power back up and respond to even the button pressing OR when it’s plugged into the charger.

That’s ridiculous.  Before 6.64, my Fitbit never had this issue.
