Setup problem
The menu display may turn off unexpectedly. Check the bracelet settings to see if there are menu display options. If it is a setting problem, just reopen the menu display options.
Software failure or update
Software update or failure may cause abnormal menu display. At this point, trying to restart the bracelet or update the software version may solve the problem.
hardware fault
If other functions of the bracelet are normal, but the menu still cannot be displayed, there may be something wrong with the screen. It is a wise choice to contact after-sales service or send it for repair.
Other factors
In addition to the above reasons, there may be other factors that cause the menu to disappear. For example, the menu is hidden due to misoperation, the bracelet system cache problem or the connection problem with the mobile APP. If none of the above methods can solve the problem, it is recommended to contact technical support or consult the user manual for a more detailed solution.
