Frequently Asked Questions

Why does Adobe Acrobat freeze on my phone when I perform simple actions?

App freezing is typically caused by outdated software versions, corrupted app cache, or insufficient device memory. Updating the app and clearing its temporary cache often resolves these crashes.

Will I lose my PDF annotations if the app hangs?

If the application hangs before it can sync or locally save, recent unsaved edits might be lost. It is recommended to ensure your app is up-to-date to prevent crashes during editing.

How do I find my starred PDFs after reopening the app?

In most mobile PDF readers, you can locate your starred or favorited files by navigating to the 'Home' tab and looking for a specific 'Starred' or 'Favorites' filter category.
