Frequently Asked Questions
Why does my PDF app say it contains bugs and needs an update?
This usually occurs when the app developer identifies a critical flaw in a specific release (such as version 25.4.1) and restricts usage via an in-app prompt to prevent data corruption, prompting you to download the patched version.
Will clearing the app cache delete my saved PDF files?
No, clearing the app cache only removes temporary system files used to speed up the app. Your downloaded PDF files stored in your phone's main storage or internal documents folder will remain perfectly safe.
How can I open an urgent PDF if my current app is completely broken?
If you cannot wait for an update, you can immediately install an alternative mobile office suite like WPS Office from the Play Store. It features robust native PDF support and will open standard PDF files without issue.
