In my case, samsung answered me and directed me to the attention center of my cell phone company where theyve follow up on my case. However I recommend you to search mobilefun, for example, I, in addition to the response from samsung I plan to buy a spare spen soon, I found them there in 32 dlls and in all colors.
Same thing happened to me. Samsung or Xfinity mobile will not do anything about it. I always had the note phones and never had this problem. It's a bad design this year.
The top of my s pen broke off today literally the 2nd time I even removed it from the phone, I think I've had the phone maybe 3 weeks now or less and the top broke off of mine also, that piece needs to be made into the pen instead of just having it molded into plastic as an insert bc now I've just had to pay 30 bucks to replace something thru Samsung than has less than 10 mins of use on it. Love my phone and the s pen for the note 9 but the pen is seriously lacking in the usable department if its gonna literally explode on the 2nd use.... kinda displeased at this moment w the fact that it broke and that the spring inside it only functioned as it should for the first use, then the top broke off of it
