Frequently Asked Questions

Why do PDF fonts display correctly on my computer but not on my Android tablet?

This usually occurs because your computer has the specific font (like Times New Roman Bold) installed in its system, while your Android device does not. If the document creator did not embed the fonts into the PDF, the Android app has to guess and substitute the missing font, which often leads to missing or incorrectly styled text.

How can I check if a PDF has its fonts properly embedded?

Open the PDF on a desktop computer using a viewer like WPS Office or Adobe Acrobat. Go to 'File' > 'Properties' and click on the 'Fonts' tab. If the fonts are packaged with the document, you will see 'Embedded' or 'Embedded Subset' listed next to the font names.

Will clearing the app cache fix the missing text issue in Acrobat Reader?

While clearing the app cache can resolve minor performance glitches, font rendering issues are typically tied to app updates or missing embedded fonts. However, you can try clearing it by going to your Android Settings > Apps > Adobe Acrobat > Storage and tapping 'Clear Cache' as a quick initial troubleshooting step.
