It gets more complicated on Android, because it gives its users more freedom both to break and to fix Amazon Prime Video. So, there are two ways out of trouble. Amazon Prime Video is like most streaming services. It runs smoothly. It's almost inevitable that you will encounter some issues at some point. This is just technology, so there can be some Amazon prime issues. Here is the first way. Clearing the storage will remove the error if it’s somewhere in the app cache.
Go to Android Settings, then to Application Manager;
Select Prime Video;
Open its tab and select “Storage”;
Tap “Clear Data” and then “OK”;
Go back to the app and try to restart the video.
If the error was about cached video, recaching will fix it. But if it doesn’t, let’s do it the hard way (like we do on iOS).
Go to Android Settings, then to Application Manager;
Select Prime Video;
Choose “Uninstall” and confirm;
Restart your device;
Reinstall the app from Google Play.
