The Simple Device Orientation Sensor (SDOS) in Windows is a software driver that allows the operating system to detect and respond to changes in the orientation of your device, typically a tablet, laptop, or 2-in-1 device. This sensor can detect whether the device is in landscape or portrait mode, and it helps adjust the user interface accordingly (e.g., rotating the screen, adjusting UI elements, etc.).
The Simple Device Orientation Sensor Windows driver ensures that the device can properly detect and manage the orientation sensor, which is particularly useful in devices with rotating screens or those that can be used both as a laptop and a tablet.
