Frequently Asked Questions

Why does changing the highlight color cause Adobe Acrobat to crash?

Changing colors can trigger a rendering bug or memory spike in certain versions of the app, causing it to freeze or crash if the device's temporary cache is overloaded or if the app version is incompatible with your current OS build.

Will clearing the app cache delete my PDF files?

No, clearing the app cache only removes temporary system files that the app uses to load faster. Your downloaded and saved PDF documents will remain intact on your device storage.

What should I do if my PDF still crashes after reinstalling?

If the app continues to crash, the PDF file itself might be corrupted or severely bloated with complex elements. Try opening a different PDF to see if the issue persists, or use an alternative reader like WPS Office.
