Since MiBox is now officially an AndroidTV device, can you access Amazon video like on Shield?
Found this old thread https://www.reddit.com/r/AndroidTV/comments/56jm3o/psa_amazon_video_works_on_the_mi_box/ but seems like Amazon had that apk removed since. I was thinking of getting MiBox but if I can't access my Amazon Prime account videos, I don't know if it's worth it. I use Amazon video, netflix, hbogo, and kodi on a regular basis.
Amazon video for Android TV isn't really available on any device other than Sony TVs and the Shield. Somebody cobbled together a thing for other ATV devices using the Android app and a custom launcher, but they got C&D'd. If Amazon access is important to you, look elsewhere. Fire TV is great if Amazon is your primary source. Otherwise, check out Roku.
