S pen does not work

[Note20Ultra]

Writing on the screenshot does not work at all using the pen, in addition to the fingerprint stop working after installing a temporary screen for your Note 20 Ultra.

Can any one help me?

I assume you mean screen protector was added? That would block the finger print sensor and pen from interacting with the phone.

Not all screen protectors work, so you can turn up sensivity and see if that helps but if not you have to find a different screen protector

What screen protector did you put on?

@Note20Ultra: If you have recently added a screen protector to your Note 20 Ultra, head to Settings > Display > Touch sensitivity, and toggle this option on. Let me know if this helps.

I'd suggest to remove the screen protector you've fitted as it's hindering the operation of your screen.

Sometimes privacy protectors cause this issue.

I use the official Samsung Tpu Screen protector that's works flawlessly with my sPen and fingerprint scanner. 

If I can be of any further help then please don't hesitate. Take care.  😎
