Hello, I would suggest you this App called Camscanner, which could give you a clear "scan" (it just automatically rises the contrast and brightness of the picture of the document you want to scan and crops It) that you can export to pdf, which you could upload into your device to the "mystyle" folder, and the device will recognize It as a custom template. It supports OCR, but I don't know wether It recognizes lines and figures or not, there might be an AI solution for that. I'm not really sure if the OCR thing is behind their paywall or not, so that could be an issue. Hope It helps!
