How to replace the S-Pen tip of a Samsung Galaxy Note handset
So, since we are on the topic of the tip – it's actually removable, and Samsung provides 5 spare ones with each Galaxy Note. Now, don't worry, it's not something that easily wears off. However, if we imagine that you are a hardcore S-Pen addict that happens to use and abuse the device extensively on a daily basis, it may just so happen that your stylus' tip winds up being bent towards the side, or its surface slightly worn, which would result in a less slick feel when jotting. Now, this will only occur once in a while, and we are pretty positive that the 5 spare tips are more than enough to last you for the phone's normal 2-year life cycle and beyond, so don't fear.
As far as how the actual switcheroo is done – it's not all that hard. Here's a step-by-step guide on how to replace the S-Pen's tip.
