trying to undertand the calibration algorithm



i am desperately seeking for a solution with the accelerometer sensor
i cannot use the phone without rotating if i have it on the table or even sometimes in my hand
sensor is off on the x axis = 5 ,
with the calibration tool i have managed to correct it to 3 but if i want to calibrate it to 0 and put it on a flat surface the calibration always fails (i think because the offset is too much it can probably correct it 2 points)
here you can see on the video near the end what i am talking about



i found the file responsible for the calibration posibbly acceleration and gyro sensor
just cannot understand the values inside there are so many numbers so i can try to manually calibrate it
location
sys/devices/14e300000.i2c/i2c-66/66-003a/input/input0/calibrator_cmd

OS is Flyme 4 (Android 4.4)
