Clearing out a path of dirt when randomly a dirt block is placed in front of me from my inventory while holding a dirt block. I am not touching the right mouse button, I keep my hand away from it, and it just does it. I have no idea what is happening. Even when getting some wood with an axe, makes it shave the wood off while I'm holding left mouse button.

I had a friend get cheated out of getting a working tablet from someone else and it was diagnosed to have ghost touches. It is when it randomly goes wherever it wants to, from app to screen to another app while no one is touching it. This is kind of the same scenario, but with Minecraft, not the device. I know this because before the latest 2 updates it hasn't done any of the right clicking madness.
