A user launches a software application on their Android tablet device. Once the software has loaded, the user reports that when turning the tablet to work the application in landscape mode, the…

If the OS-level auto-rotate setting were disabled, no applications would rotate - since other apps presumably work, the OS setting is not the specific cause.

Low battery does not disable landscape mode as a standard Android power-saving behavior.

Android apps must explicitly handle orientation changes by listening for events from the accelerometer and gyroscope sensors and calling the appropriate layout resources for portrait and landscape modes. If a developer did not implement this logic, the app ignores sensor input and remains in its default orientation regardless of how the device is held. This is an application development limitation, not an OS or hardware failure.

On Android, orientation change is automatic when auto-rotate is enabled; the user does not manually switch to landscape mode.
