Why are there difficulties with fastening or detaching the strap of the Xiaomi Smart Band 9 Active?

The strap of the Xiaomi Smart Band 9 Active is designed for a secure fit.
If you encounter difficulties with fastening or detaching the strap, please refer to the correct wearing methods as follows:
1. The strap’s buckle and hole use an interference fit to prevent the band from loosening easily. To fasten the strap, align the mushroom head of the buckle with the band hole. Place your index finger under the strap for support and press firmly with your thumb and index finger to secure it;
2. To avoid accidental detachment, ensure the short strap end (with the buckle) is not scratched or impacted by hard objects. The strap’s arc-shaped design prevents it from falling off without significant external force. If the buckle hole becomes worn or deformed due to prolonged use, consider replacing the strap to maintain secure fastening.
