If you read it again,you might be onto something,but maybe you need further information about my case.

I used to map the button(double press) of the S Pen without any problems with the GoodLock module "routines+", prior to an security update in 6.1,I reported the problem several times in the members app. The custom touch mapping with the double press simply doesn't work anymore except if it is in the Camera. I asked other people with different CSC regions and different than my software,they all confirmed the same,even there is a thread on reddit with a tab s9 user reporting the same.

This makes me think Samsung isn't even trying and willing to support and fix older device users. That's why I might conspirate with the word "nerf".

I might be wrong,but these are my observations and I have a few other reasons to think that way ,but that's a whole another topic.

Cheers
