+ *
+ * It is recommended to design feature related codes in your application for reliability.\n
+ *
+ * You can check if a device supports the related features for this API by using @ref CAPI_SYSTEM_SYSTEM_INFO_MODULE, thereby controlling the procedure of your application.\n
+ *
+ * To ensure your application is only running on the device with specific features, please define the features in your manifest file using the manifest editor in the SDK.\n
