Samsung Galaxy Book4 Pro 360 S Pen Not Recognized Windows 11

The S Pen that came with your Samsung Galaxy Book4 Pro 360 does not respond on the touchscreen – tapping does nothing, pressure sensitivity is missing in drawing apps, or the pen hover pointer does not appear. Windows 11 driver updates sometimes break the EMR digitizer that powers the S Pen.

This guide covers pen driver reinstallation, Bluetooth pairing, and Windows Ink settings to get the S Pen working again on the Galaxy Book4 Pro 360 in Windows 11.

“S Pen stopped responding on my Galaxy Book4 Pro 360 after Windows Update. Tried everything until Samsung Update showed a pending Wacom pen driver update. Problem solved.” – Jun Wei, architect from Penang

Why S Pen Stops Working on Galaxy Book4 Pro 360

The Galaxy Book4 Pro 360 uses a Wacom EMR digitizer layer embedded beneath the AMOLED display. The S Pen communicates through this layer using electromagnetic resonance – no battery needed. The Wacom or Samsung pen driver must be loaded for Windows 11 to process pen input. Windows updates can replace this with an incompatible generic HID pen driver.

• Wacom or Samsung S Pen driver replaced by generic HID after Windows 11 update
• S Pen hover not detected – pen must touch screen to register any input
• Pressure sensitivity missing in all drawing and handwriting apps
• Air Actions not working – S Pen Bluetooth button not paired

Fix 1 – Update S Pen Driver via Samsung Update

Open Samsung Update (pre-installed on Galaxy Book4 Pro 360). Check All Updates and look for S Pen Driver, Wacom Driver, or Pen Input updates. Install any pending updates. Samsung Update provides model-specific driver packages that include the correct Wacom EMR digitizer configuration for the Book4 Pro 360 display.

Fix 2 – Reinstall Pen Driver from Samsung Support

Go to samsung.com/us/support, select Galaxy Book4 Pro 360, and download the S Pen or Pen driver for Windows 11 under Software. In Device Manager, uninstall the current pen device under Human Interface Devices (look for Wacom or Samsung Pen), restart, and install the downloaded driver.

Windows Ink Setting for Pen Apps

For drawing apps like OneNote or Adobe Fresco, ensure Windows Ink is active. Right-click the desktop and check if Pen and Touch appears in settings. In drawing apps, verify that Windows Ink or WinTab input is selected. Some apps require Windows Ink specifically for pressure sensitivity on Samsung S Pen.

Fix 3 – Re-pair S Pen Bluetooth for Air Actions

For S Pen Air Actions (button shortcuts), the S Pen must be Bluetooth paired. Open Settings – Bluetooth and devices, click Add device, and follow the S Pen pairing process (hold the S Pen button while bringing it near the screen). After pairing, Air Action button shortcuts work in supported apps and on the desktop.

Fix 4 – Recalibrate Pen in Control Panel

Open Control Panel, search for Calibrate, and run Calibrate the screen for pen or touch input. Select the Galaxy Book4 Pro 360 display and calibrate for Pen input. Recalibration fixes offset drawing where strokes appear in a different position from where the pen touches the screen.
