Joking aside, if it is measuring acceleration indeed it must be in another

If it's any unit at all. Maybe one could just convert it for human
readability.
The unit is g (as in G-force). 1 G is roughly 9.8 m/s^2

Something like that was what I was hoping for...

The accelerometers measure the acceleration along the 3 axes. When the
N900 lies on the table, the z-axis points downwards, measuring the
acceleration of gravity, which is 1g. If you tilt the device, portions
of the gravity vector get measured by the x and y sensors. With the
camera on it's back,

I can't find find the Talk thread right now, but IIRC the way to reset
sensors was to shut down device and unplugging battery for a minute.
I just tried and still get the same tilted readings (0.09,

If you put your device on a levelled surface, do the sensors correctly
reflect its position, or is there a significant deviation / error as
with my device? (A good indicator is
