- Device & OS
- Samsung Galaxy tablet / Android
- Scenario
- Filling out and electronically signing a standard PDF document using a stylus.
- Observed behavior
- The goal is to seamlessly complete fillable fields and apply a handwritten signature with the S Pen that saves correctly within the PDF file.
Before committing to a specific workflow or purchasing hardware, download a test PDF form to verify that your chosen Android application correctly recognizes S Pen input and saves handwritten signatures without flattening form fields prematurely.
Using a Stylus-Compatible PDF App for S Pen Signatures
Select and test a PDF reader that fully supports Samsung's S Pen for handwritten signatures and interactive form filling.
To successfully sign and fill a PDF on a Samsung tablet, the key is using a PDF application designed to handle stylus inputs natively. Apps like WPS Office, Adobe Acrobat, and Adobe Fill & Sign are popular choices.
Download a robust PDF app from the Google Play Store, such as WPS Office or Adobe Fill & Sign, which explicitly supports stylus input and form filling.
Launch your chosen app and navigate to your device storage to open the target fillable PDF form.
Tap on the interactive text fields to type your information, or use the S Pen to write text if your tablet's handwriting-to-text feature is enabled.
Locate the signature tool within the app (often found under 'Fill & Sign', 'Annotations', or 'Edit'). Use your S Pen to draw your signature smoothly directly on the screen.
Save the completed document and open it on a different device (like a PC) to confirm that the form data and the handwritten signature are preserved correctly.

Easily Sign PDFs with WPS Office on Your Android Tablet

Frequently Asked Questions
Do all PDF apps support the Samsung S Pen?
Most major PDF apps like WPS Office and Adobe Acrobat support basic S Pen input for drawing and annotations. However, for a dedicated, professional signature, you should verify if the app has a specific 'Signature' feature optimized for pressure-sensitive styluses to ensure high-quality strokes.
Will my handwritten signature be preserved if I send the PDF to a Windows PC?
Yes, as long as you use a standard PDF application to save the document. The signature is embedded as a vector or image annotation within the PDF, making it fully visible on any standard PDF viewer on Windows, Mac, or iOS.
Can I edit the signature after saving the PDF?
This depends on the application used. Some apps flatten the signature upon saving for security reasons, making it uneditable. In WPS Office, you can manage saved signatures in your profile for future use, but once a signature is applied and the document is flattened and shared, it cannot be modified by the recipient.
