Solution 1Recommended

Troubleshoot Form Compatibility and Edit PDFs in Adobe Reader

Update the mobile application and ensure the PDF utilizes standard AcroForm technology instead of older LiveCycle formats for mobile compatibility.

LiveCycle Static Forms often lack full interactive support on mobile PDF readers. For interactive fields to appear blue and function correctly on Android, the form should ideally be saved as a standard mobile-compatible AcroForm.

1
Update the Application

Open the Google Play Store or Apple App Store and update Adobe Acrobat Reader to the latest version.

2
Edit PDF Text and Formatting

Open the PDF file in the app. Tap the 'Edit PDF' icon in the toolbar to modify text, strike through, or underline content.

3
Fill Forms and Add Signatures

Tap 'Fill & Sign' from the menu tools to enter text into form fields or to draw and insert your electronic signature.

4
Resolve LiveCycle Form Issues

If form fields remain un-editable or are not highlighted, contact the document creator to re-save and export the file as a standard, mobile-compatible AcroForm.

Frequently Asked Questions

Why aren't my fillable PDF form fields highlighted in blue on Android?

This usually occurs if the PDF was created using older form technologies, such as Adobe LiveCycle Static Forms, which have limited support on mobile devices. Requesting a standard AcroForm version from the author usually resolves this.

Can I add my signature to a PDF without printing it?

Yes. Using a mobile PDF editor like WPS Office or Acrobat Reader, you can use the 'Fill & Sign' tool to draw your signature directly on the touchscreen and place it anywhere on the document.

How do I strike through or underline text in a PDF on mobile?

Open the PDF and select the 'Comment' or 'Annotate' tool in your PDF reader. Choose the underline or strikethrough icon, then drag your finger over the text you wish to format.

Why can't I access PDF editing tutorial videos in certain regions?

Sometimes regional licensing restrictions or outdated links cause video tutorials to become unavailable. Try visiting the software's official global Help Center directly and manually searching for the specific tutorial subject.
