I don't see any other reports saying this is still a bug.

I'm using a nexus 10, didn't see it in the drop down options.

Just recently felt like checking to see if it was solved since invert y had been broken but its really disappointing to see that it's not. I had pocket edition uninstalled, so when I reinstalled it from Google play it would have gotten any recent updates.

This is a pretty bad bug for a admittedly small amount of players, since inverted isnt a popular playstyle. For most who do play inverted though, its the only way we can play. So most inverted players can't play Minecraft pocket edition without a good amount of headache trying to adjust back to the default up=up down=down

If there is a bug that makes the game unplayable, its a game-breaking bug.

[EDIT]

sorry, I just noticed the update in a different notice that it may not be fixed till 13.1 or even after.
