The G-Sensor on your HTC One X is the hardware component that senses when the device is rotated. This sensor changes the display from portrait to landscape and back based on how you hold the device. If your screen's orientation is not responding properly when you rotate the device, you can calibrate the G-Sensor, as well as adjust other display options like brightness and contrast, in the HTC One X Display Settings menu.
Press and hold the status bar from any screen on the HTC One X, and then pull the bar down to display the Notifications panel.
Tap the gear icon to launch the Settings app.
Tap the “Display, Gestures and Buttons” or “Display & Buttons” tab, depending on the available option, to open the Display Settings menu.
Tap the “G-Sensor Calibration” tab to open the calibration tool.
Lay the device on a flat surface, and then tap the “Calibrate” button. The G-Sensor on the HTC One X calibrates, then a success message displays.
Tap “OK” to dismiss the success message.
- To disable screen rotation, tap the “Auto-Rotate Screen” option to clear the check box in the Display Settings menu.
