How to Fill and Sign a PDF Form on an Android Tablet
Question details
The user needs to properly fill out, utilize dropdowns, and sign a fillable PDF form on an Android tablet without losing interactive formatting.

- Product
- Device & OS
- Android
- Scenario
- Opening a fillable PDF form created on a computer using a mobile device via cloud storage previewers or mobile reader apps.
- Observed behavior
- Interactive form elements such as dropdowns, signature fields, and date formatting stop working or disappear entirely when accessed on the Android tablet.
Ensure your Android tablet has a dedicated, up-to-date PDF reader application installed, as default cloud storage viewers often cannot process interactive form elements.
Open the PDF Directly in a Dedicated PDF App
Bypass cloud storage previewers like OneDrive or SharePoint, which lack support for interactive form features, by opening the file natively in a capable PDF reader.
Many mobile users tap a PDF link inside an email or cloud drive and try to fill it out directly in the app's default preview window. These lightweight previewers generally strip out complex AcroForm elements like dropdowns and date fields.
Locate the PDF file in your email or cloud drive app (e.g., OneDrive, SharePoint) and download it directly to your Android tablet's local storage.
Open a robust PDF application such as Adobe Acrobat Reader or WPS Office from your tablet's app drawer.
Navigate to the app's file browser, find the locally downloaded PDF document, and tap to open it.
Tap on the highlighted interactive fields to use dropdowns and enter text, or access the 'Fill & Sign' tool from the app's menu to add your signature.

Save the Document with Reader Extended Rights (PC Required)
If the PDF restricts saving form data or using specific tools on mobile devices, the original creator must enable Reader Extended Rights from a computer.
Easily Fill and Sign PDFs on Android with WPS Office
WPS Office for Android provides robust PDF tools, allowing you to easily fill out interactive forms, add electronic signatures, and save your documents seamlessly without losing field formatting.
- 1. Open the form in WPS Office: Install WPS Office from the Google Play Store, launch the app, and open your downloaded PDF form.
- 2. Interact with form fields: Simply tap on any text box, dropdown menu, or checkbox to start filling out the required information directly on your tablet.
- 3. Access signature tools: Tap on 'Tools' at the bottom menu, navigate to the 'PDF Edit' or 'Fill & Sign' tab, and select the 'Signature' option.
- 4. Draw and place your signature: Draw your signature using your finger or stylus, place it in the appropriate area on the document, and resize it as needed.
- 5. Save your progress: Tap the 'Save' icon at the top of the screen to ensure all your form inputs and signatures are permanently applied to the file.

Frequently Asked Questions
Why do dropdowns and date fields disappear when I open a PDF from OneDrive?
Cloud storage apps like OneDrive and SharePoint use basic built-in document previewers designed for quick reading. They do not support complex interactive PDF elements like dropdowns, date pickers, or signature scripts. You must download the file and open it in a dedicated PDF application.
Can I sign a PDF form on an Android tablet if it doesn't have a designated signature field?
Yes. Most advanced PDF readers, including WPS Office, feature an independent 'Fill & Sign' or 'Add Signature' tool. You can use this to manually create, place, and resize a signature anywhere on the document, even if the creator did not include a specific signature box.
Do I need a paid subscription to fill out PDF forms on an Android tablet?
Not necessarily. While some applications require a premium subscription to edit existing document text, filling out standard interactive PDF form fields and adding basic drawn signatures is available for free in apps like WPS Office.
