The stream service is very tedious because the Android PlayStore no Amazon Instant Video app, including the app is available. One should see the on the homepage refer somewhat more complicated.
Movies on your smartphone with the app, series etc look Although performing but is about the Amazon app again cumbersome. Wiser it would have been on the Instant Video app to make a nice tidy interface what you can more easily and clearly arranged dial movies and series.
So bit more creativity to the developers :-)
