This is the Full review of the Android TV Box Rikomagic MK12 that features the Amlogic S802.
Benchmarked using Geekbench 3, Antuntu, SpeedTest. 3D Mark and Epic Citadel.
Played 1080P and 4K videos on XBMC and tested on games Cars, Despicable Me, Beach Buggy, Asphalt 8 and GT Racing 2 which all worked great.
Also mirrored my Iphone, Ipad and Imac to this Android TV Box.
The only downside was that the latest version available from Kodi was not able to run on this machine, so hopefully Rikomagic will be able to fix this issue.
