- Product
- Acrobat Reader
- Device & OS
- Mobile
- Scenario
- Opening a secured interactive PDF form containing text fields and radio buttons on a smartphone or tablet.
- Observed behavior
- Interactive form fields become hidden or disabled when the secured PDF is opened in Acrobat Reader for mobile.
Check if the interactive form works normally on your mobile device before applying any document security to confirm the issue is related to permission restrictions.
Test Without Security and Adjust Form Permissions
Remove the security restrictions temporarily or adjust the document permissions to explicitly allow form filling.
Acrobat Reader for mobile devices lacks full support for certain protected documents. When strict security is applied without granting specific interactive rights, the mobile app often hides these elements automatically.
Open the original, unprotected PDF document using your preferred desktop PDF editor.
Navigate to the document security or protection settings and ensure that the 'Filling of form fields' or 'Interactive elements' option is explicitly permitted in the restrictions.
Save the changes, transfer the newly secured file to your mobile device, and open it to verify if the interactive fields remain visible.
Use a Supported Desktop Environment
Bypass the mobile limitation entirely by filling out the secured form on a desktop computer.

Frequently Asked Questions
Why do my PDF text fields disappear on Android or iOS?
Many mobile PDF readers, including Acrobat Reader for mobile, have limited support for advanced security features. When a document is protected, the app may automatically hide interactive elements to prevent unauthorized modifications.
How can I protect my PDF form without losing interactivity on mobile?
When applying security settings, limit the restrictions to extracting pages or full editing, but specifically check the box to allow 'filling in form fields' and 'signing' before distributing the document.
Can I fill out secured PDF forms on a smartphone?
Yes, but it depends on the mobile app's capabilities. If your current app hides the fields, try using a different PDF reader with higher compatibility for encrypted interactive documents, or explicitly allow form filling in the original file permissions.
Does WPS Office mobile support PDF form filling?
Yes, the WPS Office mobile app provides excellent support for reading, filling out, and signing standard PDF documents, making it a reliable alternative when encountering format compatibility issues.
