Z Fold 4 s pen doesn't work properly

[lilyfigue608]

Recently, my s pen has not been working correctly on all parts of the main display of my z fold 4. It's almost like there are dead spots on my screen. I can't write on these parts. However when I touch those areas to swipe with my finger/move the screen it's fine. It won't work with the pen though. Not sure if this started after one UI 5. I wasn't using my fold as much in recent weeks as my SIM card was in another phone but now it's back and I'm disappointed to be running into this issue. Not sure if it's happening to anyone else.

@lilyfigue608 Do you have a case on the phone? If so, does it have magnets? or have you attached magnets to your phone? 

Magnets will disrupt the ability to use the S Pen. Removing the magnets will restore proper operation.

No magnet on my case. Switch between a Samsung case and a 3rd party. Just so strange to me. Phone hasn't been dropped or anything either

@lilyfigue608 You may have to take it in for a service evaluation. 

No problems on my Fold 4 running UI 5.

Just in case, try going into recovery and clearing the system cache and repair apps.

Worth a shot. Thank you
