4k video with any android ver

I am absolutely upset with the software support. this is 2019 and I can’t get any android image with 4k support. this is a shame. what is the point of having h/w support of 4k if I can’t use it because of crappy s/w? This is disgusting, I am going to sell out this pice of h/w, it is useless at all for me.

HI: Android system needs Allwinner’s support, we have been communicating with the Allwinner soc vendor. Due to Allwinner limited human resources, still, need times to wait.
