How to Copy Text and Add Annotations to a PDF on Android
Question details
Users are unable to copy text or add annotations to PDF documents while using Reading Mode on an Android app.

- Product
- Adobe Acrobat Reader
- Device & OS
- Android 5.1
- Scenario
- Attempting to select text for copying or using annotation tools while reading a PDF document on an Android device.
- Observed behavior
- Text selection and annotation functions are completely disabled or unavailable when the application is set to Reading Mode.
Ensure your PDF document is not restricted by a permissions password, as document security settings can prevent copying and annotating regardless of your current viewing mode.
Switch Viewing Mode to Enable Copying and Annotating
Change your PDF reader from Reading Mode to Continuous or Single Page mode to restore full text selection and annotation capabilities.
Reading Mode is specifically designed to provide a clean, distraction-free reading experience on mobile screens. By design, it temporarily disables interactive tools like text copying and annotations.
To regain access to these features, you simply need to switch back to a standard document viewing mode.
Tap anywhere on the center of the screen while viewing your PDF to reveal the top and bottom application menu bars.
Locate the View or Layout icon (often represented by an eye or a page symbol) and tap it to exit Reading Mode.
Choose either 'Continuous' or 'Single Page' mode from the viewing options.
Long-press on the text you wish to copy to bring up the selection handles, or tap your annotation tools to highlight and mark up the document.

Use WPS Office to Easily Annotate and Copy PDF Text on Android
WPS Office provides an incredibly intuitive PDF viewing and editing experience on mobile devices. You can effortlessly navigate standard document layouts while maintaining full access to powerful text selection, highlighting, and annotation tools.
- 1. Open the PDF: Launch WPS Office on your Android device and open your PDF document.

- 3. Access Annotations: Tap the 'Tools' icon at the bottom of the screen, then navigate to the 'Annotation' tab.
- 4. Apply Markups: Select your preferred tool, such as Highlight, Underline, or Text Box, and apply it directly to the document text.

Frequently Asked Questions
Why can't I copy text from my PDF document on my phone?
If you are in Reading Mode, text selection may be disabled by the app's design to prevent accidental taps. Alternatively, the PDF might be a scanned image (which requires OCR to become selectable) or protected by a security password that explicitly restricts copying.
How do I copy text to translate it while reading a PDF?
First, ensure your app is set to an editing or standard viewing mode like 'Continuous'. Long-press to select the text you want to translate, choose 'Copy', and paste it into a translation app. Some PDF readers also feature built-in translation options directly in the selection menu.
Does switching out of Reading Mode change my document layout?
Yes. Reading Mode reformats and reflows the text to fit your mobile screen better. Switching to Continuous or Single Page mode will display the document in its original, fixed layout, which may require zooming in to read comfortably.
Can I extract text from a scanned PDF on Android?
Standard PDF readers treat scanned documents as images, meaning you cannot normally long-press to copy text. To extract text from a scan, you will need to use a mobile PDF application that includes OCR (Optical Character Recognition) capabilities.
