FYI

Kodi won't update to the newest version. Older android boxes less than version 5 will not be able to update Kodi. There is other Kodi app clones that will work just like the updated version and using the same apps. My Gica, SPMC, JesusBox.

My Kodi box review.

I've started with the old reliable Raspberry Pi before going to android base Kodi. I tried numerous boxes like MX, MXIII, Tronsmart vega, Tronsmart Draco, MXQ Pro, HM8 Smart, Nvidia Shield. They all did well, but the older boxes weren't updating anymore. The MXQ Pro and HM8 have the newer android hardware so Kodi updates, but the NVidia Shield is my best box. It updates hardware, software and remotes by itself.

Raspberry Pi and OSMC

is still the most stable but the slowest.

OSMC (open source media centre) is the best software for Kodi. Besides the Nvidia Shield, OSMC software updates itself.
