Question details
The user is unable to access the marker and annotation tools in the Android version of Adobe Acrobat Reader for a PDF file transferred via Google Drive.

- Product
- Adobe Acrobat Reader
- Device & OS
- Android, Windows 10
- Scenario
- Opening and annotating a PDF document on an Android device after transferring it from a Windows 10 PC through Google Drive.
- Observed behavior
- The marker tool functions correctly on Windows 10 but is missing or unavailable when opening the same PDF on the Android app.
Ensure your Android device has a stable internet connection to download app updates and sufficient internal storage space to save the PDF file locally.
Download the PDF Locally and Verify Permissions
Downloading the file from Google Drive to your local storage and checking document permissions can restore access to the missing annotation tools.
Opening PDFs directly from cloud storage platforms like Google Drive can sometimes restrict file functionality, opening them in a read-only preview mode. Downloading the file locally ensures the PDF reader has full read and write access.
Open the Google Play Store on your Android device and ensure Adobe Acrobat Reader is updated to the latest available version.
Open Google Drive, locate your PDF, tap the three vertical dots icon next to the file, and select 'Download' to save it to your local device.
Launch Adobe Acrobat Reader, navigate to the 'Files' tab, select 'On This Device', and open your recently downloaded PDF.
Tap the blue pencil icon at the bottom right of the screen, select 'Comment', and check if the Highlight or Marker tools are now available.

Use WPS Office to Easily Annotate PDFs on Android
If your current PDF reader limits your mobile editing capabilities, switch to WPS Office. It offers a complete, easy-to-use set of PDF annotation tools directly on your Android device without compatibility issues.
- 1. Install WPS Office: Download and install WPS Office for free from the Google Play Store on your Android device.
- 2. Open Your PDF: Launch WPS Office, tap 'Open', navigate to your device's local storage, and select your PDF file.
- 3. Access Annotation Tools: Tap 'Tools' at the bottom of the screen, swipe to the 'Annotation' tab, and select your preferred marking tool.
- 4. Highlight and Save: Use your finger or stylus to mark the document, then tap the 'Save' icon to keep your annotations.

Frequently Asked Questions
Why do PDF annotation tools disappear when opening files from Google Drive?
When files are opened directly from a cloud drive, apps often load them in a restricted preview mode to save data and memory. This read-only state temporarily disables advanced editing and annotation tools.
Can I highlight a password-protected PDF on Android?
No. If a PDF is protected with a permissions password that restricts commenting or editing, the highlight and marker tools will be disabled regardless of the device or app you are using.
Are annotations made on a Windows PC visible on Android?
Yes, as long as the PDF was properly saved with the annotations embedded and you use a fully compatible PDF reader on Android, all highlights and comments will be visible across different operating systems.
