The only way to fix a stylus pen tip is to replace it. For both the Apple Pencil and the Samsung S Pen, the manufacturer's documented repair procedure is to install a new tip, not to repair the worn, broken, or bent original part.
How to replace an Apple Pencil tip
To replace a worn, broken, or bent tip on an Apple Pencil, grip the old tip and unscrew it counterclockwise. Then, screw the new tip on clockwise until it is snug. The fitted tip should leave a tiny gap, about the thickness of a sheet of paper, between the tip and the Pencil body. Replacement tips are available for Apple Pencil Pro, Apple Pencil (2nd generation), Apple Pencil (USB-C), and Apple Pencil (1st generation).
How to replace a Samsung S Pen tip
To replace a worn, broken, or bent tip on a supported Samsung S Pen, use the included changing tool or tweezers to gently pull the old nib out. Samsung includes a removal tool/tweezers for models that include it in the box, including S Pen Pro, S Pen Fold Edition, S Pen Creator Edition, S Pen for Ultra model phones, and Tab S model S Pens. Then, insert the new nib by hand. Samsung says the S Pen tip should slide in easily; one Samsung page says you will not hear or feel a click when the tip is installed, while another says there will be a slight click when the tip is fully inserted, so this varies by model or support page.
What to do if your S Pen doesn't include spare tips
Samsung notes that some device packages may not include spare tips. If your device does not come with replacement tips, you should contact an authorized service center, as availability depends on the S Pen model. Some S Pen models do not have user-replaceable tips. If the S Pen is not recognized, Samsung says to check the S Pen tip and remove/reinsert it correctly.
