ok im having calibration issues when holding my phone in landscape mode. ive dug around and found the calibration file for the accelerometer and other sensors. it will let me change it but it wont let me save it. also if you view it in root explorer text editor it wont show. but if you view it in es file, root browser, or root explorer text viewer it shows as -2 0 0 0. and coincidentally its off by about 2 degrees. the file path is sys>devices>virtual>sensors>accelerometer_sensor>c alibration. it just wont allow me to save the file. any ideas?
