Scenario
Editing lengthy PDF documents on a mobile device where application stability might be compromised.
Observed behavior
Unsaved text and document edits are permanently lost if the application closes unexpectedly because there is currently no built-in autosave feature.
Before you start

Before making extensive edits to lengthy PDF documents on your mobile device, ensure you have sufficient battery life and manually save a backup copy of your original file to device storage.

Solution 1Recommended

Save Your PDF Documents Manually and Frequently

Since an autosave feature is currently unavailable, adopting a habit of manually saving your work is the most effective way to prevent data loss.

When working on mobile devices, unexpected app crashes or OS resource management can suddenly close background applications. Relying entirely on the app to preserve the state is risky without a dedicated autosave function.

1
Commit Your Edits

After adding text, filling forms, or making annotations, immediately tap the 'Done' or checkmark icon on the top left of the screen to commit your edits to the document.

2
Save a Copy

Periodically open the top-right menu (the three-dot icon) and select 'Save a Copy' to create versioned backups of your lengthy PDF documents.

Save Your PDF Documents Manually and Frequently
Best Practice: Saving a copy locally to your device storage is often safer than relying exclusively on live cloud edits over an unstable cellular connection.
