Galaxy S26 Ultra S Pen Not Working: Not Writing or Detected
When the S Pen is not detected on the Galaxy S26 Ultra, the cause is usually that it is not fully seated, a magnetic case or a thick screen protector. Inserting the pen in the right orientation, turning off Power Saving and resetting the S Pen in settings usually solves it. If a specific area of the screen does not respond, the digitizer may be faulty; use the Samsung Members test to tell the difference.

簡潔な回答 TL;DR
Insert the S Pen with the tip first until it seats fully, then remove it. Take off magnetic cases and thick screen protectors, turn off Power Saving and Airplane Mode, and reset the S Pen from Settings > Advanced features > S Pen. If one area of the screen does not respond, run the Samsung Members hardware test; if the problem continues, service is required.

01 — ステップごとの解決策
How do you fix it? Step by step
-
ステップ 1/7
Insert the S Pen in the correct orientation
Push the S Pen in with the tip first until it seats fully, wait a few seconds and pull it out. The phone detects the pen with a magnetic sensor; if it sits halfway, the inserted and removed notifications can behave incorrectly.
-
ステップ 2/7
Turn off Power Saving
Go to Settings > Battery > Power Saving. If 'Limit apps and Home screen' is on, wireless S Pen features and some pen functions may be disabled. Turn Power Saving off completely during testing.
-
ステップ 3/7
Turn off Airplane Mode
Airplane Mode cuts the S Pen's wireless connection. Swipe down to open Quick Settings and confirm Airplane Mode is off. With it off, remove and reinsert the S Pen.
-
ステップ 4/7
Remove the magnetic case and screen protector
Magnetic cases, MagSafe rings, car mounts and thick glass protectors can disturb the S Pen's electromagnetic field. Remove them all and write directly on the screen. If the issue disappears, replace the accessory.
-
ステップ 5/7
Reset the S Pen from settings
Go to Settings > Advanced features > S Pen and use 'Reset S Pen'. This restores the pen connection and pressure sensitivity to defaults; your personal data is not deleted.
-
ステップ 6/7
Run a hardware test with Samsung Members
Open Samsung Members, go to Support > Diagnostics and run the S Pen test. The test shows which part of the screen does not detect the pen. A consistent dead area means the digitizer or display hardware may be faulty.
-
ステップ 7/7
Update the software, then contact service if needed
Install the latest One UI build from Settings > Software update. If the problem continues and the Samsung Members test shows a screen fault, contact an authorized service center. If the S Pen tip is worn, try a spare tip.
If the tip wears out quickly, a hard screen protector or heavy pressure may be the cause; get spare tips from Samsung.
02 — People also ask
よくある質問
The phone shows 'removed' while the S Pen is inserted. Why?
The sensor in the slot may not detect the pen because of dust or debris. Clean the slot with dry air and push the S Pen all the way in, then wait a few seconds.
Can a screen protector affect the S Pen?
Yes. Thick glass protectors and films that trap an air gap can weaken the electromagnetic signal. Test the pen directly on the screen; if it works, use a thinner protector.
Can the S Pen tip be replaced?
Yes, on most Galaxy S Ultra models the tip is user-replaceable. Use the spare tips and the removal tool that came with the phone; never use a pin or needle.
When is service required?
If the S Pen works on another S26 Ultra but not on yours, or one area of the screen never detects the pen, the hardware may be faulty. Take the Samsung Members test result to an authorized service center.
