I want my app to show a progress bar when I start a download or upload. For this I am using fileTransfer plugins, local Notifications. The progress value is given according to the change of a variable that receives the value of an observable. when updating the notification I used the update method, but every update it vibrates again.
NOTE: When the phone has volume, it does not vibrate, result I want to achieve in silent.

this.apiService.getContObservable().subscribe(res => {
  console.log('Novo Valor: ', res)
  if (res == 1) {
    this.cont = res / 100
    this.aux = res
    this.criarNoficacao()
  } else if (res == 100) {
    this.cont = 0
    this.aux = 0
  } else {
    this.cont = res / 100
    this.aux = res
    this.notificacao.update({
      id: 1,
      sound: null,
      vibrate : null,
      progressBar: { value: this.aux }
    });
  
  }
})
