>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Plugin File
>    Affects Versions: 4.3.1
>         Environment: Cordova iOS, Android.
>            Reporter: Michael Stanford

> Versions:
> Cordova: 6.4.0
> Cordova File System Plugin: 4.3.1
> iOS: 10.0.2
> Cordova iOS: 4.3.1
> Android: 6.0.1
> Cordova Android: 6.0.0
> Desktop OS: OS X 10.12.1
> Desktop Safari: 10.0.1
> AWS S3 SDK is documented at:
> http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3/ManagedUpload.html
> On both Android and iOS, using the Cordova File System plugin, and in OS X Safari using
the File Input HTML tag, I seem to be successfully retrieving a File/blob in every case -
see the listings below.
> In each of the three cases, I invoke the Amazon S3 SDK upload API with this File object.
In desktop Safari the file uploads correctly and appears in the S3 bucket correctly. 
> In iOS and Android, the file appears to upload correctly (no errors), but all that appears
in the bucket is the 15-byte text string "\[object Object\]".
> I am using the same HTML and JS files  in all three cases; after collecting the File
object the code is identical, and because they run from the same HTML page, the meta information
is also the same.
> In case it is something to do with security settings, I set all the permissions and CORS
on the S3 bucket to wide open for anybody to do anything. This may still be the root of the
problem, but the filename gets through OK, and gets written in every case, and the file contents
gets through correctly from the desktop browser. 
> So I am inclined to think that the File/Blob from Cordova behaves differently somehow
than the File/Blob from Safari, and returns the string "\[object Object\]" in response to
the method that the S3 API uses to retrieve an array buffer.
> Here are listings from the Safari Debugger, showing the file objects from the desktop
Safari and the Cordova iOS:
> {code}
> Params:
>   ACL: "public-read"
>   Body: File
>     lastModified: 1477360985000
