What apps do you personally use on your android box? I use a racked version of spotify for adfree streaming, and stremio with some plugins for all tvshows. I used Kodi in the past but it tended to crap out on the box (its a mibox 4K). I would love to get some more apps for pirating content. Local content is usually a hard find.
You need to setup the addons on your phone first. Then when logged into the same account on the TV app, click sync addons.
