S25 Ultra S Pen Button

[userK51OmLdkMe]

Does anyone know what the S25 Ultra S Pen button button does because mine does nothing? 

[TipsyTrex]

Activates erasor and brings up the quick access pen menu. All other features were removed because samsung doesnt care about appealing to niche use cases anymore.

@userK51OmLdkMe The button on the end of the S Pen is only used to insert and remove the S Pen. 

The side button, as @TipsyTrex stated, is primarily used to enable the eraser.

For me, it is a fidget button. Lol!
Like @LongHiker said it is just for removal and insertion.
