HarmonyOS 鸿蒙Next 使用“按照预置振动效果”方式的振动回调都成功但手机不振动是怎么回事

按照文档实例开启预置振动：

import { vibrator } from '@kit.SensorServiceKit';
import { BusinessError } from '@kit.BasicServicesKit';

try {
  // 查询是否支持'haptic.effect.soft'
  vibrator.isSupportEffect('haptic.effect.soft', (err: BusinessError, state: boolean) => {
    if (err) {
      console.error(`Failed to query effect. Code: ${err.code}, message: ${err.message}`);
      return;
    }
    console.info('Succeed in querying effect');
    if (state) {
      try {
        // 触发马达振动
        vibrator.startVibration({
          type: 'preset',
          effectId: 'haptic.effect.soft',
          count: 1,
          intensity: 50,
        }, {
          usage: 'unknown'
        }, (error: BusinessError) => {
          if (error) {
            console.error(`Failed to start vibration. Code: ${error.code}, message: ${error.message}`);
          } else {
            console.info('Succeed in starting vibration');
          }
        });
      } catch (error) {
        let e: BusinessError = error as BusinessError;
        console.error(`An unexpected error occurred. Code: ${e.code}, message: ${e.message}`);
      }
    }
  })
} catch (error) {
  let e: BusinessError = error as BusinessError;
  console.error(`An unexpected error occurred. Code: ${e.code}, message: ${e.message}`);
}
