Malfunction of S-pen

[MRCrossDias]

Hi, can someone help me? My brother gave me a S23 Ultra, and the s-pen is working only on the left side of the screen... I don't know what to do, besides that everything is fine.

Ps.: I did a test on Samsung Notes, and u can look below

I just did the test through this app and that's the max score of my S-Pen

@MRCrossDias It looks like the digitizer failed. You will need to contact Samsung support to get it repaired.
