What to Do If You Can’t Add Signature to PDF

If you encounter any difficulties while trying to add a signature to a PDF document on your Android device, here are some possible fixes:

1. Ensure that you have a compatible PDF reader or signature app installed. If not, try installing Adobe Acrobat Reader, PDFelement, or DocuSign, as mentioned earlier.
2. Check if the document has any restrictions that prevent signature additions. Some PDFs may be password-protected or have security settings that disable editing or signing.
3. Make sure you have the necessary permissions to modify the PDF document. If the document is read-only, you won’t be able to add a signature to it unless you have the required access or ownership.
4. Consider converting the PDF document to a different format, such as a Word document or image file. Once converted, add your signature and then convert it back to PDF format if necessary.

2. Enable biometric authentication: To enhance the security of your digital signature, enable biometric authentication, such as fingerprint or facial recognition, on your Android device. This ensures that only you can access and apply your signature to a PDF document.
