> I always wondered if one could repurpose side-mounted fingerprint sensors (ex. Samsung Galaxy Fold) as a swipe-to-scroll mechanism.
Given how fp sensors are capacitive, this should totally be doable. Several phones (including my pixel 5) allow using rear fp sensors for opening/closing the notification shade.

Aah.. I miss that on my framework laptop. I had it on my old HP ProBook in the Synaptics settings. Chiral and (1 finger) edge scrolling were amazing. I'd suggest using ZMK/QMK and a touchpad from mouser if anyone wants to DIY one today.
My last Samsung with a back-mounted fingerprint sensor (A40) could do that (there was an option in the settings to enable scrolling with the fingerprint sensor).

An old phone if mine (not sure, but I think from OnePlus) supported gestures in the fingerprint sensor (back mounted in this case)
There also used to be some lovely touchpad tech called "chiral scroll", which allowed for iPod-like scrolling. No idea where that went, patent hell?
