As far as I understand the terminology, "standard support" means we have someone in the core team who has access to the device and regularly runs boot tests on the actual hardware and is willing to attempt to fix issues that are found (best effort, not a guarantee). It does not mean all hardware features of the board are working.

onleplus 8t is running mainline kernel so don't expect it can work as an android phone. At the moment cellular and camera is not working. Dsiplay, touchscreen, wifi and bluetooth work.

@amazingfate can tell that.
