How to Complete and Sign Fillable PDF Forms on Android Tablets

Product: PDF Reader/Editor apps
Device & OS: Android (Samsung tablet)
Scenario: Completing a digital service form, entering customer data, signing it with a stylus, and returning it via email or cloud storage.
Observed behavior: The user needs a straightforward workflow to ensure form fields are correctly filled, the signature is preserved, and the document is easily saved and exported.

Before you start

Ensure your PDF document is natively fillable (contains interactive form fields) and that your stylus or S Pen is connected and functioning properly.

Solution 1Recommended

Use Adobe Acrobat Reader for Android

Adobe Acrobat Reader provides robust tools to fill out interactive PDF forms and draw signatures directly on your tablet.

Adobe Acrobat Reader is widely used for handling PDF documents on mobile devices. It properly renders interactive form fields and integrates well with stylus inputs like the Samsung S Pen.

Open the PDF document

Launch the Adobe Acrobat Reader app, navigate to your device storage or recent files, and open the PDF attachment.

Fill out the form fields

Tap on the designated text boxes or checkboxes within the document. Your on-screen keyboard will appear, allowing you to enter the required customer information.

Add a handwritten signature

Select the 'Fill & Sign' tool from the bottom menu, tap the signature icon, and use your S Pen to draw your signature. Tap 'Done' and drag the signature to the correct line on the form.

Save and share the completed form

Tap the three-dot menu icon to save a copy of the completed PDF to your device. You can then use the 'Share' icon to attach the file to an email or upload it to your preferred cloud storage service.

Non-interactive PDFs: If tapping the form fields does not let you type, the document may not be properly formatted as an interactive PDF. You will need to request a fillable version from the creator or use the 'Add Text' tool to manually place text over the blank lines.

Frequently Asked Questions

Why can't I type into my PDF form on my Android tablet?

If the PDF is not an interactive form (often called a 'flat' PDF), tapping the fields won't open a keyboard. You must either use a text box tool within your PDF editor to overlay text manually or ask the sender for a digitally fillable version.

Can I save my handwritten signature for future forms?

Yes, most professional PDF editing apps, including WPS Office and Adobe Acrobat, allow you to create and save a default signature. You can simply tap the signature tool to insert it on future documents without needing to redraw it every time.

Will the recipient be able to see the filled data and signature when I email it?

As long as you save the document after filling it out and send that saved copy, the recipient will see all the entered data and your handwritten signature on any standard PDF reader.
