Samsung may be considering integrating a built-in S Pen and slot into the TriFold2, similar to a Galaxy Note, as demonstrated by leaked patent
For those that didn't know, I'm actually 4 days late to this rumor, so I apologize if you're just now seeing this. Just wanted to make sure this rumor is really credible, and right now it is looking pretty valid.
That being said, we're not really sure if this idea would come to fruition with the final release of the TriFold2, but it's definitely under consideration by Samsung.
Basically the way this would work is that the S Pen would slide into the device through the slot located at the hinge area, rather than going beneath the ultra-thin screen. My guess on why it would be like this is to prevent any interference with the rumored digitizer layer that Samsung could also be integrating into the TriFold2, which could make the device itself a tad bit thicker. Well obviously they need this because how else would the S Pen work lol.
Assuming all this information is true, this may of course crank up the price of the TriFold2, but it would also make it a truly, ultra-premium device, and Samsung's first-ever foldable to rock a built-in S Pen and slot.
