Fix Missing Keep Screen On Option in Adobe Acrobat Reader iOS

Product: Adobe Acrobat Reader
Device & OS: iOS
Scenario: Reading PDF documents on an iPad or iPhone.
Observed behavior: The Keep Screen On option is missing from the app's interface, forcing the user to tap the screen continuously to prevent the device from going to sleep.

Before you start

Verify your iOS device's global Auto-Lock settings under Settings > Display & Brightness, as this determines how quickly your screen turns off when an app does not override it.

Solution 1Recommended

Verify Document-Specific View Settings

Determine if the issue is isolated to a single PDF, as document owners can customize view restrictions that disable certain app features.

PDF creators have the ability to lock specific view settings or apply restrictions to a document. If the Keep Screen On option is missing, it might be due to the properties of the specific PDF you are currently reading.

Open an alternative PDF

Launch Adobe Acrobat Reader and open a completely different PDF file from your device or cloud storage.

Check the viewing options

Navigate to the reading settings or view options menu within the new document to see if the Keep Screen On toggle appears.

Identify document restrictions

If the option is available in the second PDF but not the first, the original document has restricted view settings set by its owner.

Document Restrictions: You cannot bypass document-specific view settings unless you have the owner's permission or the password to remove the PDF's security restrictions.

Solution 2

Update Adobe Acrobat Reader

Ensure you are using the latest version of Adobe Acrobat Reader, as outdated versions may contain bugs affecting the display of settings.

Frequently Asked Questions

Why does my iPhone screen turn off while reading a PDF?

Your device's global Auto-Lock setting controls screen timeout. If the PDF reader app lacks a 'Keep Screen On' feature or if it fails to activate, the device will sleep based on your iOS Display & Brightness settings.

Can a PDF owner restrict my viewing options in Adobe Acrobat?

Yes, PDF creators can apply security parameters and view restrictions to a document. This can disable certain app features, including custom viewing modes or screen timeout overrides.

Is there a way to force my iOS screen to stay on permanently?

You can change your global device settings by going to Settings > Display & Brightness > Auto-Lock, and setting it to 'Never'. Remember to change it back later to save battery life.
