220-1101 Question 324
Single answerOrientationA user reports that a company-issued tablet works normally in portrait mode, but when they rotate the device sideways during meetings, the screen remains vertical and does not switch to landscape. The display is clear and touch input works correctly. You verify that the operating system is responsive and no external monitor is connected. Which action should the technician take FIRST to resolve this issue?
- A
Enable or disable the screen rotation lock in the operating system settings
- B
Replace the tablet's LCD panel because landscape mode is not supported
- C
Update the tablet's GPU firmware to restore automatic orientation
- D
Reinstall the touch driver because touch calibration controls screen rotation
Show answer and explanation
Correct answer: A
Explanation
This question tests practical troubleshooting of mobile device orientation, a Core 1 objective area. In real-world support, a tablet that stays in portrait mode despite being rotated often has rotation lock enabled or auto-rotate disabled. Best practice is to start with the simplest and least disruptive step: verify orientation settings in the operating system. If that does not resolve the issue, the technician could then check whether the device's accelerometer/gyroscope sensors are functioning, verify that the OS and device drivers are current, and confirm that no accessibility or kiosk settings are enforcing a fixed orientation. This follows standard troubleshooting methodology: identify the issue, establish a theory, test the simplest solution first, and escalate only if needed.
- A. Correct.
Correct. On tablets and other mobile devices, failure to rotate between portrait and landscape is commonly caused by orientation lock or auto-rotate being disabled in the operating system. Since the display and touch input are otherwise working, checking the rotation setting is the most appropriate first troubleshooting step.
- B. Incorrect.
Incorrect. An LCD panel does not determine whether portrait or landscape orientation is supported; the same screen can display either orientation. Replacing the display would be unnecessary and ignores the more likely software or settings-related cause.
- C. Incorrect.
Incorrect. Graphics or device firmware issues can affect display behavior in some cases, but they are not the first thing to suspect when a tablet simply will not auto-rotate. A technician should check basic orientation settings before moving to more invasive updates.
- D. Incorrect.
Incorrect. Touch functionality and screen orientation are separate features. Although some devices integrate multiple sensors and drivers, a touch driver reinstall is not the first step when touch is working properly and only auto-rotation is failing.
