Check for App Updates

Open the Google Play Store on your Samsung device, search for 'Adobe Acrobat Reader', and tap 'Update' if a newer version is available.

Navigate to your device's 'Settings' menu, scroll down, and select 'Apps' to view your installed applications.

Clear the Cache

Find and tap on 'Acrobat Reader' in the list, select 'Storage', and tap the 'Clear Cache' button at the bottom of the screen.

Frequently Asked Questions

Why does text disappear when I type in a PDF on my phone?

This is often caused by a rendering bug in the PDF application, an outdated app version, or incompatibilities with specific custom fonts embedded within the original PDF document.

Does the Samsung Galaxy Z Fold3 have known compatibility issues with PDF editors?

Because of its unique foldable aspect ratio and dynamic screen resizing, some mobile apps may struggle to render text boxes properly when transitioning between screens. Keeping the app updated ensures you have the latest optimization patches.

How can I recover the text that disappeared while editing?

If the text disappeared from the text box before saving, it was likely an interface glitch and the input was not registered. You will need to re-type the text after restarting the app or clearing the application cache.
