If your Samsung Galaxy S25 Ultra is not detecting the S Pen, you may notice that Air Actions stop working, hovering does nothing, or the phone does not respond when the pen touches the screen. This can feel like the S Pen is completely dead, even when it is fully inserted. In most cases, the issue is caused by connection glitches, settings, or temporary software bugs in One UI 7, and it can be fixed with a few simple steps.
Why Your Samsung Galaxy S25 Ultra S Pen Is Not Detected
- The S Pen connection is temporarily lost or not synced.
- Air Actions or S Pen features are disabled in settings.
- The S Pen battery is drained or not charging properly.
- Magnetic interference from phone cases or accessories.
- Minor software glitches affecting S Pen detection on One UI 7.
1. Reinsert the S Pen
The S Pen reconnects automatically when inserted back into the phone. If the connection is interrupted, reinserting it forces the device to detect and pair with it again.
Remove the S Pen from the slot, and then insert it back into the phone.
Wait a few seconds, and then remove it again to check if it is detected.
2. Enable Air Actions
Air Actions must be turned on for the S Pen to communicate with your phone wirelessly. If this setting is off, the S Pen may appear unresponsive or disconnected.
Open Settings, and then tap Advanced features.
Tap S Pen, and then tap Air Actions to turn it on.
3. Reset the S Pen
Resetting the S Pen refreshes its connection with your Galaxy device. This helps fix pairing issues and restores normal functionality.
Open Settings, and then tap Advanced features.
Tap S Pen, and then tap the three-dot icon to select Reset S Pen.
4. Check S Pen Battery Status
The S Pen uses a small internal battery for Air Actions. If it is drained, some features may stop working even if basic touch input still works.
Open Settings, and then tap Advanced features.
Tap S Pen, and then check the battery level under Air Actions.
5. Remove Magnetic Accessories
Strong magnets from cases or accessories can interfere with the S Pen’s detection. This can cause missed input, weak response, or complete disconnection.
Remove your phone case, and then take off any magnetic accessories.
Use the S Pen again, and then check if it starts responding normally.
6. Restart Your Phone
A restart refreshes system services that control S Pen detection. It is a simple fix that often resolves temporary bugs.
Swipe down from the top right to open Quick Settings.
Tap the Power icon, and then tap Restart.
7. Update Software
Software updates often include fixes for S Pen performance and connectivity issues. Keeping your phone updated ensures better stability.
Open Settings, and then tap Software update.
Tap Download and install, and then follow the prompts if an update is available.
When your S Pen is not detected, it usually comes down to connection issues or settings that need to be refreshed. Once you go through these steps, your Samsung Galaxy S25 Ultra should recognize the S Pen again and restore all its features.
