I am using S3 for file uploads.

It works fine for video, images on Android and it works fine for videos, audio, images on iOS. Please help figure out why this only for videos on Android. Thanks.

No files, tests, or entry points are named. Start by tracing the Android video-upload path and compare its S3 signing request with the working Android image and iOS video cases. Done means Android video requests are accepted by S3 without SignatureDoesNotMatch errors.
