camera - after pressing on take picture button it takes 1-2s to output the image

Inizia riproducendo il ritardo con l’esempio live di Ionic o con l’esempio della documentazione della fotocamera di Capacitor, usando la chiamata mostrata a Camera.getPhoto e i log di Android. Traccia il tempo dallo scatto della foto fino all’output dell’immagine e confrontalo con l’attività del thread principale e di Filesystem riportata nel report. Il lavoro è completato quando l’output della fotocamera è materialmente più reattivo sui dispositivi Android interessati.

Current behavior:
running the ionic live example or code example from ionic camera docs, in both examples it takes 1-2s for the camera component to shoot and output an image.
it feels unresponsive.

Expected behavior:
an instant (as much as possible) image output like native camera.

Steps to reproduce:
take a photo using camera component

Related code:

code implementation:

takePhoto(): Observable<Photo> {
  const getPhotoOptions: ImageOptions = {
     resultType: CameraResultType.Base64,
     source: CameraSource.Camera,
     quality: 100
  };
  const photo: Promise<Photo> = Camera.getPhoto(getPhotoOptions);
  return from(photo);
}

note: changing CameraResultType from Base64 to Uri did not help.

Other information:

verified on several android phones.
