Hi there, I bought my tv box 2 years ago. Called Rikomagic MK12:

Quad Core Android PC MK12
OS version:Android 4.4
CPU:Amlogic S812
RAM:2G
Program:16G

I have a few questions:
1) Does this mean that my old android tv version 4.4 is not compatible with many tv apps?
2) If so, how can I update the 4.4 version?

Thanks!
