I have a Samsung S23 Ultra. From last 2 days When writing on the phone with the S Pen, the screen continues to register writing when the pen is not actually touching the screen after each stroke (especially when the pen is close to the screen). It creates sort of a "drag' or a "tail" between strokes. Frankly quite annoying.
As per your concern, we would request you to kindly perform the following steps to resolve your issue.
Settings> Advanced features> S Pen> Air actions> More> Reset S Pen.
In case the issue still occurs, please visit the service centre for a physical inspection of your device. You can locate your nearest service centre with this given link: https://www.samsung.com/in/support/service-center/
