Nokia 5233 Symbian motion sensor stopped working after nokia software udpate

[Rohit Prakash]

hi
I have nokia 5233 phone. I use internet and I received message from Nokia that it can automatically update core software of my phone from Menu --> Settings --> Phone --> Phone Management --> Device Update. Now my phone's software is updated latest but only problem is that motion sensor is not working. When I tilt screen, its orientation do not change.

Is there way to rollback the changes or I am stucked ? I have double checked that "Motion sensor " is enabled but still not working.
