What to do when touchscreen does not recognize S pen input on certain screen areas?

There are a few different external factors that can interfere with the S Pen's function. Some things that can prevent your screen from recognizing your S Pen are third-party cases or magnetic force, outdated software, and where you are interacting on the phone's screen.

Any third-party cases with magnetic closures or clasps can cause interference with S Pen recognition. If a magnetic case or cover is attached to the device, it is recommended to remove the attached case or cover and try again.

If a magnetic case or cover is attached to the device, the device may not recognize the S Pen's actions, and the S Pen may not work properly. Therefore, please remove the attached case or cover and try again.

Also, if you use the S Pen in certain areas affected by magnetic force, such as around the camera or speaker, the S Pen may not be recognized properly due to magnetic force. If the recognition sensitivity has decreased, raise the pen a little bit and use it.

Screen protectors can cause inconsistent motion and pressure when using the S Pen. Screen covers can have the following issues:

• Too hard or rubbery surface for writing.
• An uneven surface, which affects consistency.
• The thickness of a screen protector can affect screen sensitivity.
• A dirty or old screen protector can affect performance.

If the pointer appears on screen but no touches are recognized or a great deal of pressure is required, the tip may need to be changed. If your S Pen came with replacements, you can change the S Pen tip.
