Where does Amazon Prime on Android store it's files. If I could find them I could then remove the DRM. Unfortunately, I can't find them. :D

The video files are stored in /data/user/0/com.amazon.avod.thirdpartyclient/files/downloads/amzn1.dv.gti.xxxxxx
Inside an episode r movie dir the files are stored in 0 and 1.
/0 - This contains the Video files split into encrypted split .atv files.
/1 - This contains the Audio files split into encrypted split .atv files.
The files are encrypted with PlayReady, the DRM licence files needed to decrypt are located in /data/user/0/com.amazon.avod.thirdpartyclient/files/playready/system
You need "root access" to get to these files. If you don't have a rooted Android, just use an emulator that supports root. I recommend Nox or Memu as they work fine. As was already said there is no way to "hack" these, or decrypt them. They are not a single video file they split into thousands of files.
Some scene groups due claim to release WEB-DL for Amazon and there has been WideVine exploits but those are not done on Android. Also Amazon on Android uses h265 for some strange reason, where WEB uses h264 so they are not even the same streams we get on PCs.
