Frequently Asked Questions

Why does Adobe Acrobat Reader run slowly on my Android device?

Slowness is typically caused by a buildup of cached data, an outdated app version conflicting with your Android OS, heavily graphical PDF files, or low available device memory.

Will clearing the app cache delete my saved PDF files?

No, clearing the app cache only removes temporary files generated by the app to improve its performance. Your downloaded and saved PDF documents will remain safe and intact on your device.

What should I do if clearing the cache doesn't fix the slow opening times?

If the problem persists, try uninstalling and reinstalling Adobe Acrobat Reader from the Google Play Store. Alternatively, you can use another lightweight PDF viewer like WPS Office to ensure immediate access to your files.
