Uninstall and Reinstall Acrobat Reader

Performing a clean reinstallation of the app clears corrupted cache data and resolves underlying synchronization glitches triggering the false purchase prompt.

This is the most effective troubleshooting step for unexplained app behavior on Android devices. Removing the app deletes faulty temporary files that might be confusing the app's billing verification system.

1
Uninstall the Application

Locate the Adobe Acrobat Reader icon on your Android home screen or app drawer. Long-press the icon and tap 'Uninstall' or 'Remove App' from the context menu.

2
Restart Your Android Device

Press and hold the power button on your smartphone (e.g., Samsung Galaxy S21) and select 'Restart'. This clears your system's temporary memory and ensures a clean state.

3
Reinstall from the Google Play Store

Open the Google Play Store app, search for 'Adobe Acrobat Reader', and tap 'Install' to download the latest, most stable version of the application.

4
Log In and Verify

Launch the newly installed application, sign in to your Adobe account, and use the app normally to check if the error prompt has stopped appearing.

Frequently Asked Questions

Why does Acrobat Reader say 'Could not complete purchase' when I didn't buy anything?

This is typically caused by a background glitch where the app tries to verify your subscription status with Google Play Services but fails. It triggers a false error message even if you are using the free version.

Will uninstalling Acrobat Reader delete my PDF files?

PDFs saved to your Android's internal storage (like the Downloads folder) or synced to cloud drives will remain safe. However, files stored exclusively within the app's hidden local directory might be lost, so it's best to move important files to a visible folder or cloud drive before uninstalling.

How do I find my exact Android OS version on a Samsung Galaxy device?

To find your Android version, open your device's Settings app, scroll to the bottom, and tap 'About phone'. Then tap 'Software information' to view the Android version and One UI version.

Are there other free apps to open PDFs on Android?

Yes. If you want to avoid ongoing bugs with your current reader, all-in-one productivity suites like WPS Office include powerful, built-in PDF viewers and editors that are completely free to download.
