Help messed up spirit level

[afarkas]

Hi everybody ...
I have a strange problem on my galaxy pro (with the newes 2.2.2 firmware installed in certified samsubg service) ...
Any spirit level / bubble app i install is just messed up the way, that shows oposite values...

For example: i calibrate on flat table the two direction bubbles and the middle bulls eye bubble...
Then lifting up the longer side of the phone results in showing that the shorter side is lifted (which is nonsens) and again, lifting the shorter side show that the longer is lifted ...

Anyone else experienced this kind of problem?

I must say, that in system settings, in display - accelerometer calibration, the built-in system spirit level which performs the calibration is showing everything correct ...

Thanks for answers ...
