Why does it do this since update?

I am #9 on leaderboard. I'm huge trying to maneuver through board, I tilt my slightly, it autorotates to portrait mode, making my accelerate button disappear, I die instantly.

Seems like holding phone very still doesn't even work, the slightest movement will make it autorotate throwing off your movement and also making so that you cannot even accelerate until it rotates back.
