The Samsung Galaxy S23 Ultra features a built-in S Pen designed to offer seamless precision for writing, drawing, and controlling your device. But if your S Pen isn’t working properly—such as unresponsive input, intermittent Bluetooth disconnection, or lag—it can affect your productivity and user experience. Fortunately, most S Pen issues are easy to diagnose and fix. In this article, we’ll explore the possible reasons behind S Pen malfunction on the Galaxy S23 Ultra and how to solve them.

🖊️ Common S Pen Problems on Galaxy S23 Ultra
- S Pen not writing or responding to touch.
- Air Actions (gestures) not working.
- S Pen disconnected or not detected.
- Lag or delay in input.
- Bluetooth features not functioning.
✅ S Pen Not Responding to Screen Input
If your S Pen is not writing, drawing, or selecting items on the screen, it could be due to hardware obstruction, screen protector issues, or settings.
Fix:
- Restart the phone – A quick reboot can refresh device drivers.
- Remove screen protector or case – Some third-party protectors interfere with S Pen sensitivity.
- Test in Safe Mode:
- Press and hold the Power button, then tap and hold Power off, and select Safe Mode.
- Test the S Pen here. If it works, a third-party app may be the cause.
Check Settings:
- Go to Settings > Advanced Features > S Pen.
- Enable S Pen to text, Air view, and Show pointer to ensure detection features are working.
📶 Bluetooth Disconnected or Not Detected
The S Pen on the S23 Ultra includes Bluetooth LE (Low Energy) for remote functions like camera shutter, media control, and Air Actions.
Fix:
- Check S Pen Connection:
- Go to Settings > Advanced Features > S Pen > Air Actions.
- Ensure it says “Connected” under S Pen remote.
- If not, remove and reinsert the S Pen to force a reconnect.
- Charge the S Pen by inserting it into the phone for at least 30 seconds.
- Toggle Air Actions OFF and ON again to refresh the connection.
🔄Air Actions Not Working
Air Actions allow you to control your phone with S Pen gestures. If these aren’t working, it’s likely due to gesture miscalibration or disabled settings.
Fix:
- Go to Settings > Advanced Features > S Pen > Air Actions.
- Make sure Air Actions are turned on.
- Tap the 3-dot menu > Reset S Pen, then re-pair the S Pen.
- Practice gestures slowly—fast or incorrect angles can fail to register.
🔋S Pen Needs Charging
Bluetooth features on the S Pen won’t work unless it’s charged.
Fix:
- Insert the S Pen into its slot for at least 30 seconds to 1 minute.
- Ensure your phone is not in power-saving mode, as this may disable Bluetooth features.
- Avoid using cases that interfere with proper docking or charging of the S Pen.
🧼Debris in the S Pen Slot
Dust or particles inside the S Pen slot can cause poor connection or failure to detect.
Fix:
- Use a clean, dry soft brush or compressed air to gently clean the slot.
- Do not insert pins or sharp objects which can damage internal contacts.
🧠Software Bugs or Outdated Firmware
Occasionally, a software bug can cause issues with S Pen functionality or responsiveness.
Fix:
- Go to Settings > Software update > Download and install to check for any pending updates.
- Samsung often includes S Pen improvements in One UI or firmware patches.
🔁Reset S Pen Settings
If none of the above works, resetting your S Pen settings can often fix unknown configuration problems.
Steps:
- Go to Settings > Advanced Features > S Pen.
- Tap Air Actions.
- Tap the 3-dot menu (top right) and choose Reset S Pen.
- Wait for the device to re-pair with the S Pen.
🧪Run Diagnostics via Samsung Members App
Samsung’s built-in diagnostic tool can help you identify if there’s a hardware fault.
How to use:
- Open the Samsung Members app.
- Go to Support > Phone diagnostics > S Pen.
- Follow the prompts to test functionality.
📦S Pen Is Damaged or Faulty
If your S Pen is physically damaged or malfunctioning, it might need replacement.
Signs:

Solution:
- Try using another Galaxy S23 Ultra S Pen (from a friend or store).
- If that works, your S Pen may need replacement. Contact Samsung Support or visit a service center.
🚫 S Pen Features Disabled in Battery Saver
Battery saver mode can disable Bluetooth and background services required for S Pen gestures.
Fix:
- Go to Settings > Battery and device care > Battery > Power saving.
- Turn it OFF, or ensure Limit apps and home screen is not enabled.
- Set S Pen and system apps to Unrestricted in Battery usage settings.
