Solution 1Recommended

Isolate the PDF File and Update the App

Determine if the crash is caused by a specific corrupted PDF file or an outdated app version, and clear temporary data.

App crashes can often be isolated to either a corrupted document or a software glitch within the current app version. Testing multiple files helps narrow down the root cause.

1
Test multiple PDF files

Open a different PDF file in Acrobat Reader Mobile and tap the Fill & Sign tool. If it only crashes on the original file, that specific PDF may be corrupted or too complex.

2
Update the application

Open the Google Play Store, search for 'Adobe Acrobat Reader', and tap 'Update' if a newer version is available to fix known bugs.

3
Clear app cache

Navigate to your device Settings > Apps > Acrobat > Storage, and tap 'Clear Cache' to remove corrupted temporary files.

4
Restart your device

Reboot your Android phone or tablet to clear the system memory and resolve temporary background conflicts.

Isolate the PDF File and Update the App
Reporting to Adobe: If the app crashes across all PDF files even after updating, record a screen video of the crash and note your Acrobat and Android versions to provide to Adobe Support.

Frequently Asked Questions

Why does Acrobat Reader only crash on one specific PDF?

A single PDF may cause crashes if it contains corrupted elements, overly complex interactive forms, or incompatible scripts that the mobile application cannot process properly.

Will clearing the app cache delete my saved PDFs?

No, clearing the app cache only removes temporary background files used to speed up the app. Your downloaded and saved PDF documents will remain safely on your device storage.

How do I find my Android OS version to report the bug?

Go to your Android device Settings, scroll down and tap 'About Phone' or 'About Device', and look for 'Android Version' or 'Software Information' to find your exact OS version.
