Libreelec abandoned their efforts to support AMLogic hardware in any useful way (in a pursuit of a purist vision that ignores usablility) so Coreelec is the only software that supports AMLogic hardware in a fully useful way. However beyond a limited range of Single Board Computers even Coreelec doesn’t guarantee to support all AMLogic devices. It does its best to support those devices it has access to and this is where a thread like this points the way towards the degree of support many of those Android boxes have under Coreelec. Read these threads carefully before making any purchase decisions. You may find that many of the Android boxes do not have all of their hardware features supported under CE.
If you want to use Libreelec you are currently limited to using x86 computers or Raspberry Pi boards.
