The S Pen interference issue on the Galaxy S25 Ultra can be frustrating, especially if you're a frequent user of the stylus. The problem often arises due to magnetic attachments.
Using strong magnetic attachments can interfere with the S Pen's signal, causing it to malfunction or not connect properly. This is because the magnetic fields can disrupt the S Pen's radio frequency (RF) signals.
Many users have reported experiencing this issue, with some even mentioning that it's a common problem with magnetic attachments.

Magnetic Interference Issues
Magnetic accessories can interfere with your S Pen.
The Galaxy S25 Ultra shows a warning when you use a magnetic case from Fiberborne, stating that magnetic accessories can interfere with your S Pen.
This is not a new issue, as the Galaxy S24 Ultra also showed a similar warning when using magnetic accessories.
The magnets in accessories can cause your S Pen to not write correctly or cause Air commands to occur unintentionally.

Folks at Android Central noticed that when they used a Samsung silicone case with a MagSafe adapter, the issue didn't pop up, suggesting that the type of case material, thickness, or distance between the phone and magnets might play a role.
The S Pen on the Galaxy S25 Ultra lacks Bluetooth connectivity, which might seem like it should prevent magnetic interference issues.
However, the alert still appears, raising questions about whether the removal of Bluetooth was a last-minute decision or if Samsung forgot to get rid of the alert on its new premium phone.
Ryan Haines from Android Authority tested the device with a magnetic Peak Design wallet and confirmed that the S Pen suffers from the issue, with drawing abruptly stopping when the S Pen overlapped the magnetic accessory.
The phone also notifies the user about the issue, saying “Magnetic accessories can interfere with your S Pen: The magnets in accessories can interfere with the signals your S Pen sends to your phone. They may cause your S Pen to not write correctly or cause Air commands to occur unintentionally.”
S Pen Behavior and Accessories
The S Pen is having some issues with magnetic accessories on the Galaxy S25 Ultra. The magnets in these accessories can interfere with the signals the S Pen sends to the phone, causing writing to stop or Air commands to occur unintentionally.
Folks at Android Authority and Android Central have both experienced this issue with magnetic cases. They noticed that the S Pen didn't work properly when used directly above the magnets, but it worked fine in other areas.
The Galaxy S25 Ultra shows a notification when using magnetic cases, warning users that magnetic accessories can interfere with their S Pen. This notification is similar to the one on last year's Galaxy S24 Ultra, which had a Bluetooth-enabled S Pen.
Using a MagSafe adapter with Samsung's official silicone case doesn't trigger this notification, suggesting that the device uses the distance between the magnets and the S Pen as a "trigger" for the notification.

Recurring Magnetic Interference
The Galaxy S25 Ultra's S Pen is facing a recurring issue with magnetic interference. This problem is not new, as it also affected the Galaxy S24 Ultra.
Magnetic accessories can cause the S Pen to not write correctly or trigger Air commands unintentionally. This is due to the magnets in accessories interfering with the signals the S Pen sends to the phone.
The issue has been observed with various magnetic cases, including the Fiberborne case with MagSafe support. When this case is used, the phone shows a notification warning about the potential interference.
The distance between the magnets and the S Pen may also play a role in triggering the notification. This is suggested by the fact that the alert did not appear when attaching a MagSafe adapter to Samsung's official silicone case.
The removal of Bluetooth from the Galaxy S25 Ultra's S Pen has raised questions about whether this decision was made at the last minute or if Samsung forgot to remove the alert.
