Stock answer from fitbit will be that your phone is not compatible. They are really not android friendly, but it's a nice looking watch. What I've had to do while waiting over a year is 1. Go to blue tooth. 2 select the versa 3 forget the versa 4 turn off blue tooth 5 turn on blue tooth 6 find the versa and pair 6 go to the fitbit app and sync. You will have to do this every time you want it to sync. Oh and the only notification you will receive consistently is how many steps are left to hit you 250 an hour. Good luck.
