While you are calibrating, I hope you have done the following...
before starting, make sure the screen is clean, and that the sensor is not obstructed.
Place on a flat surface where there is no movement.
make sure the room is well lit and bright.
Start the calibration by pressing start, and make sure you or nothing else is nowhere near the phone (or shall I say above the phone, where it is sitting)
IF being careful during calibration still fails you, then you might have a physical problem.
