How to Fix Stylus Markup Behavior Changed in Adobe Acrobat
Question details
The user is looking to restore the automatic pen-detection feature in Acrobat that allowed drawing with a stylus while the Hand tool was selected.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to use a stylus for PDF markup with the Pencil tool while keeping the Hand tool active.
- Observed behavior
- Acrobat only performs the currently selected command. The 'Auto-detect pen hardware to enable markup' preference is missing in newer versions.
Verify your current version of Adobe Acrobat, as recent updates have permanently removed the automatic pen-detection preference.
Revert to a Previous Version of Acrobat
Since the auto-detect pen hardware feature was removed in recent updates, downgrading to an older version restores the functionality.
If your workflow heavily relies on using the stylus automatically without manually switching tools, reverting to a previously supported version of Adobe Acrobat is currently the most effective workaround.
Open your system's application manager and completely uninstall the current, updated version of Adobe Acrobat.
Navigate to the official Adobe Acrobat installer archive and download an older version that supports stylus auto-detection.
Install the older version and immediately navigate to Preferences to disable automatic updates, preventing the software from upgrading and removing the feature again.
Submit Feature Feedback to Adobe
Request the engineering team to bring back the missing preference by submitting official feedback.

Why did Acrobat remove the automatic pen detection?
Software updates often streamline features or change underlying hardware interaction models. The specific toggle was removed in newer builds, altering how the stylus interacts with the Hand tool.
