Shame or not, but this decision is taken indirectly by Samsung and directly by TeamHacksung. Samsung has all their drivers closed source, the developers has absolutely no insight into anything that Samsung has laid their hands on. It's nearly impossible to make it work. And even if it would be possible, it would require many hours...no correct me....weeks of hard work to fix it, in a improper way. Further on, nobody except you seem to be using TvOut, therefore, the team has put that feature at the very bottom of the bug-fix-list. And remember that they never manage to get all the way down to the bottom before new, more important bugs has popped up, and new Android versions has been released. I would use other alternative apps on the Play Store to do this if i were you.
Perfect, thanks.
Additinal Note: we'll never be able to fix all bugs on Samsung Phones. These phones are simply to much messed up.
If you wanna run aosp based roms, buy nexus.
Even if the hardware is not the most powerful, it's running smoother and better.
