Frequently Asked Questions:

Q1: Does Android have any built-in coding tools?
answer. Not for PDFs, unfortunately. Unless your phone manufacturer specifically added this option, like Samsung. However, there are markup tools for images. If you don't need to resend a PDF in that exact format, you can take a screenshot of the document you want to sign, open it in your phone's gallery, and then use the built-in markup tools to draw a signature on the image.

Q2: Why don't some PDF files allow me to sign?
answer. If you're not allowed to sign a particular PDF file, it may be related to the document's security certificate. You can check its security options using your PDF editing software, but this may require access to a computer. Alternatively, ask the author if there are any restrictions on the PDF file and request an unsecured version.
