The Galaxy S25 Ultra’s S Pen has dropped Bluetooth support and the associated Air Actions. However, it retains its classic “Warn if S Pen is left behind” safety feature.

Samsung’s Galaxy S25 Ultra S Pen offer the valuable safety feature that alerts users if they leave the S Pen behind. This feature does not rely on Bluetooth, as the device can determine whether the S Pen is in its holster. If the user removes the S Pen and walks away with the phone while the screen is off, they will receive a warning notification.

Users can enable this warning feature through the “More S Pen settings” menu in the device’s Settings app.
