We'd recommend leaving the screen protector on your phone as it'll save the screen from scratches and what not! But if you'd like to remove this, it's entirely up to you.
It's easily removed with your nail @Prefect88 but take into account the screen then is susceptible to scratches.
Personally I removed mine as I'm not prone to the plastic feel, and replaced it with a Whitestone Dome Glass Screen Protector.

Hi Was yours a Galaxy S20 FE that you put the Whitestone Dome Glass on ?
