By default, the Honor Band 5 comes with functions like Daily Tracking, Heart Rate, Workout, AliPay, etc. While I am sure, functions like Daily Tracking and Workout are essential to fitness trackers, you can do without dedicated functions for AliPay or Message Center, especially if you plan to use the band strictly as a fitness tracker.
To customize the functions, head over to the Honor Band settings, and select Function Customization. Now, tap on the little cross icon next to the ones you want to remove.
At the same time, you can also hold and drag the important functions to the top. Once done, tap on the Save icon at the top-right corner.
