Do you think it's encryption related? Is it any faster without encryption? Not sure if we need to aim for some crypt optimization on mobile platform or look elsewhere.
Previously, there was a huge difference in transfer time between encrypted and unencrypted files, but in Ver1.17.3 (build 10170300), the difference seems to have diminished. For a 3.9GB file, the transfer speed is now 17MB/s with encryption and 20MB/s without encryption. I don't know why, but it's significantly improved. I updated the S3Drive app on Google Play after my last test.
