Galaxy S25 Ultra's S Pen is faulty

Recently, Samsung officially launched the Galaxy S25 Ultra with the included S Pen bute accessory.

The S25 Ultra's S Pen is as good a stylus as last year's. It has a 0.7mm tip and supports 4,096 levels of pressure sensitivity. It's perfect for drawing or handwriting. However, without Bluetooth, the S25 Ultra's S Pen loses some of the features that set it apart from other styluses.

Galaxy S25 Ultra's S Pen is faulty

After its launch, users discovered that the S Pen was suddenly faulty, inaccurate, and had unwanted touch commands. It was likely caused by a magnetic accessory, not a faulty S Pen or phone.

The S24 Ultra previously had a similar issue when users used Fiberborne cases. This resulted in an error message when using the S Pen, warning that the magnetic accessory could cause interference, causing the S Pen to malfunction or perform unintended Air commands.

Many users have reported similar issues. Notably, the issue seems to be resolved when using the MagSafe adapter with an official Samsung case. This suggests that the thickness of the official case may create enough of a gap to minimize magnetic interference.

Samsung has not yet officially responded to this phenomenon.

It is known that the S Pen's touchless writing and command operations on the screen are based on the phenomenon of electromagnetic induction. The phone's screen will create an induction magnetic field, inside the S Pen there is a coil to convert the magnetic field into energy to maintain the S Pen's operation. Therefore, it is obvious that using a magnetic case affects the S Pen.

To limit the situation of the S Pen being affected, users should buy genuine accessories or non-magnetic accessories for the Galaxy S25 Ultra.
