Does anyone know of a scanner app in the Play store that takes advantage of the button on the Note 9 S Pen? I'm hopeful that there's an app that will allow me to scan a document by pressing the button on the S Pen rather than an on screen button.
I'm curious what kind of situation you're using this to prefer taking the photo in the scanner app via the spen. Any time I use a scanner app, I'm already holding the phone itself and the spen would make it more cumbersome.
Not saying your question isn't valid, just curious what makes your situation unique.
