Using my s pen pro yesterday, the tip of the nib broke away leaving the remains of it inside. So s pen tool to replace tip is out of the question. I tried the tip on Google, others had luck with heating a needle and popping it in. Came out with the the needle. Unfortunately I'm with the rest where it hasn't worked for me 😔. I'm not sure how it happened, but I believe Tempered glass screen protectors don't help. Which is what is on my tab s7+.
