I have a Samsung Note 5 and it comes with a small pen/ pointer thing. It can be used instead of you’re finger on the touch screen, to write and do a lot of other things I’m sure if i bothered to read the manual.
MY question is, how does it work? I know the acting as a finger part, but it has a button on the side, also when you hold it near the screen a little circle appears on the display. It doesn’t have battery or any device [f2f, Wi-Fi) to communicate with the phone. As far as I can tell its just a stick of aluminum, so how can the phone recognize it when I hold it am inch from the screen?
It does actually have “a device that communicates with the phone” that is powered by the phone itself. That is actually pretty old computer tech–back in the early 1990s I had a Wacom tablet with a pen that worked the same way.
BTW, the newest S Pen is Bluetooth. And I’m not finding a link now, but I recently saw rumors that Apple is trying to put a camera in their version of a stylus.
