Unoptimized APK

Did you try giving only the basic options as per the documentation ? I’m just trying to narrow down the possibilities. Also check whether you are able to take image from a default camera app ?

const options: CameraOptions = {
  quality: 100,
  destinationType: this.camera.DestinationType.FILE_URI,
  encodingType: this.camera.EncodingType.JPEG,
  mediaType: this.camera.MediaType.PICTURE
}
