gyro.attitude lags on Samsung Galaxy S2

Hello. I'm trying to control a camera with Input.gyro, and it works nicely on iPhone 4s, iPad 2 and a Samsung Galaxy Tab 10.1, but when I try it on a Galaxy S2, the gyro seems to have some kind of inertia, and follows the movement way too slow.

Does anybody know what can make it work like this?

Thank you.
