In the United States Patent and Trademark Office (USPTO) application filed on June 30, 2015, Samsung has requested a new feature called Write on the PDF.
The patent says that this new function is "computer application software for mobile phones, smart phones, tablet computers, portable media players and handheld computers enabling users to annotate and save PDF documents, images and files."
Samsung's Screen Write function is already one of the most popular on the Note experience, allowing you to write on any screen and save your notes or handwriting as a screenshot and your local photo gallery, but writing on PDFs at the moment is somewhat difficult. First, you have to activate the Screen Write with the S-Pen, take a picture of the screen, then write on it. Samsung's Write on PDF feature will likely allow you to write directly on the screen, without needing to take a screenshot or activate Screen Write it to have. Instead, you'd select the function in your settings, then write on PDFs immediately.
Outside of the description, there's nothing else said about this feature, but it is exciting to think about the notes line and how much smarter it will get with this feature. Samsung just upgraded its two-year-old Galaxy 3 with Smart Select, a feature that allows you to "clipboard" texts and images simultaneously. Samsung's always been at the forefront of the software experience with its feature-packed philosophy, and write on PDF just made the smartphone-buying experience exciting again.
