It's great to see you around @Praveen_. If you are having problems setting up your tracker, I recommend restarting your device. After the restart process, follow one more time the setup procedure from your Android Fitbit app. But before, please check that your phone is a compatible mobile device. If your phone is not compatible, try the setup process from a computer.
Let me know the outcome.
