Help G-Sensor calibration

[NumbChops]

How do I calibrate the gravity sensor on this phone?
(LG optimus f7)

The orientation is off by a couple of degrees, which defeats the auto-leveling feature of the open-camera app.

Thanks!

Try GPS Status - free at Play. The "rotate 3 times around each axis" calibration should do it.

I did both calibrations (compass, and pitch/roll with averaging) and the error remains.

But in messing with it I noticed that magnitude of the error differs with orientation. So if I rotate the phone180 degrees, positioning the volume switches on top, it is accurate enough for the camera app.

Thanks
