reading orientation angle from a gyroscope

I need to get orientation angle readings from the gyroscope block in the Simulink support package for android devices, I have made an app on my android device and this app contains gyroscope block, but I don't need angular velocity! I need angles in degrees, I tried to connect the gyroscope with an integrator, but the readings weren't correct! the values keep increasing even if I stopped moving!

Are you saying that the outputs from the gyroscope block are 0, but the integrator keeps generating an increasing angle when fed these 0 inputs?

[Noor Zeid]

yes, If the output is zero the integrator keeps increasing!
