While demonstrating a product video, a sales representative reports that their Android smartphone remains in portrait orientation, even when the device is turned on its side. Motion-controlled racing games still respond correctly to tilting, and a reboot did not resolve the problem. Which action should a support technician perform FIRST to restore normal screen rotation?
Calibrate the accelerometer using the device's hardware diagnostics utility.
Verify that the auto-rotate/portrait-lock setting is disabled in the quick settings menu.
Install the latest available Android OS update to patch the rotation driver.
Replace the device's motion-sensor assembly because it has failed.
Because motion-controlled games still respond to tilting, the device's motion sensors are functioning. The most common reason the display will not change orientation is that the auto-rotate (portrait-lock) option has been disabled, typically from the quick settings shade. Re-enabling auto-rotate should immediately allow the screen to switch between portrait and landscape. Calibrating sensors, installing updates, or replacing hardware are unnecessary until basic settings have been verified.
