There's few similar posts concerning Spen unable to connect which also happened to my N10. Most likely the capacitor battery inside the pen is already reaching its end of life. To confirm, my suggestion is for you to visit to the nearest SC and ask them to check. They normally will do a quick test by swapping with a new Spen. Spen life span is around 2 years++ or even earlier. Trust me, your wallet will be lighter by RM109 😉.

Your theory + 1. I have went through shoper and lazada and found that some S Pen are selling below RM90 mark which came with remark: uncertified Samsung product. Some buyers has claimed that it is working with Air Actions and some said no. Thinking to try if I need to replace my S Pen for then 2nd time.
