I'd love if my cellphone had a lateral button like old portable radios had to adjust the volume but with the sole purpose of scrolling. Scrolling on the screen is annoying, my finger covers the content and I must be careful not to click something. I really can't believe I'm the only one desiring such a thing.
Oh man, these looked so awesome. I miss these phones sometimes. There was something cool about seeing what features different phones had. Nowadays, it's basically iOS vs Android, where both OSes do pretty much the same things, and it's all about the apps.
Sony had these on their Clié (Palm OS) devices as well.
I’ve only ever had first-party Palm handhelds, but the scroll wheel (Sony had some nifty name which is eluding me) always seemed very appealing for single-handed use.
I had a SonyEricsson P800 (the first of that series) and it had the same wheel, but IIRC was plastic made (just like the rest of the phone). Oh man I was barely 20yo back then and I feel bad for the hype I had while waiting the phone to actually come out and buy it. I also remember I paid an insane amount of money for it, which then became standard a few years later thanks to Apple.
The Blackberry 7100t had a side scroll/job wheel like this along with a body narrower than other blackberries thanks to its 20 key qwerty-ish keyboard (2 characters per key). It still ranks as one of my favorite mobile devices. Great ergonomics paired with just enough web browsing capability to be helpful during emergencies; I would spend my morning Metro ride touch typing email drafts on it. It had its flaws of course, but the side jog wheel and narrow physical keyboard added up a “spark” of feeling like it was on to something.
Non sequitur: Another long forgotten device that still bounces into my thoughts every so often is the Psion REVO. 8MB RAM, 36MHz ARM processor, and full QWERTY keyboard that fit into your (back) pocket —- better paper specs than the hand-me-down 386sx I was using a few years before! One of these days I’ll dig though storage and see if I can resurrect it.
> 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).
I'd love something like that. But I would want that to have tactice clicks, like mouse scrolling wheels, so that it can also be used for paging in book readers.
Which speaking of, there is a niche there for a product that I think is actually realistically doable at small scale. On Android, most book readers can be configured to flip pages with volume up/down, which is extremely convenient for one-handed reading. No such luck on iOS, though, where those buttons cannot be taken over by apps. It would be nice to have some kind of case for iPhones that incorporated dedicated page up/down buttons along those lines, just connecting to the actual phone via Bluetooth and presenting itself as a keyboard.
I would assume it'd also work with literal Page Up/Down keys, however that is exposed for keyboards when using Bluetooth. The important part is having that on the phone itself, placed such that when you hold it with one hand, the thumb is conveniently placed on the page down key, so that one only needs to push slightly to flip to the next page. That's what makes Android phones so convenient for reading over long periods of time compared to iPhones, where you have to lift the thumb and tap the screen for every page.
My samsung phone has the fingerprint scanner in the side power button (the only location that makes sense, IMHO). Software should be able to read gestures from this same sensor, no?
edit: Sorry, thinking out loud. A quick Google search confirms that my phone already has this feature in settings. Unfortunately, the gesture is mapped to showing/hiding the notification panel, instead of screen scrolling.
Some old (pre-smart, pre-camera, chunky ones with small B&W LCD screens) cell phones had a side scrollwheel that was used for menu navigation. I think it was clickable too.
The only more modern take on that that I know of was Marshall's "audiophile" Android phone [0] from 2015, which had a side scrollwheel for volume, but not sure if it was used for navigation.
My first cellphone (Sony) had this. I think it was https://images.app.goo.gl/Xc1RtzQSurxcFktt7
I even wonder if there wasn't haptic feedback. It was so cool at the time and I still miss it.
The dials on all the "medium-end" digital cameras I've owned always worked reliably despite many years of regular use, as do mouse scroll wheels, so I gather you're correct about cheap components.
Come to think of it, the scroll wheel on my Logitech G502 — three-way clickable, switchable between free-scrolling and traditional mode — would work well in sort of handheld hardware scrolling device, and an electromagnetic scroll wheel of the sort used on some newer Logitech mice would work even better, as it could be configured in a free-scrolling mode with variable friction.
Reminds me of when I jailbroke an old iPhone and the only thing I really actually used the jailbreak for was making a long press on the volume buttons a previous / next song button. I actually really miss it.
