MI Box, like MI smartphones, offers mid-range streaming devices at a mid-range price. Operating with the Android OS, most of the Google apps like Play Store, YouTube are preinstalled with it. With the Play Store, you can install apps and games for your MI Box. In the same way, you can install Amazon Prime Video on the MI box.
But there is a catch in it. In recent years, Amazon and Google are not in good terms. Amazon Prime Video doesn’t support Chromecast and in-return Amazon Prime Video is not available in the Play Store for Android TV OS. This issue is solved now and both made peace.
