Problem Causing while on Video Editing

I'm experiencing a frustrating issue with video editing on my Samsung Galaxy S25 Ultra.

Whenever I try to split an audio or video clip at a specific point, the cut happens at a different position. Sometimes the timeline jumps, skips frames, or moves unexpectedly, making precise editing almost impossible.

This happens in every video editing app I've tried, not just CapCut.

Has anyone else experienced this issue on the S25 Ultra? Is it a Samsung One UI bug or a touchscreen-related issue? Any solutions?
