Question details
The user is unable to use the Adobe Acrobat app in multi-window or split-screen mode on their Android device.

- Product
- Adobe Acrobat Mobile App
- Device & OS
- Samsung Galaxy F62 (Android)
- Scenario
- Attempting to view PDF files in split-screen mode alongside another application.
- Observed behavior
- The app displays a message stating it is not available in multi-window mode, preventing continuous document viewing while multitasking.
Ensure your device's operating system and the Adobe Acrobat app are fully updated, as multi-window compatibility is often improved in newer software versions.
Force Multi-Window Support via Android Developer Options
Use Android's built-in developer settings to force apps to resize, bypassing the app's default multi-window restrictions.
Android includes a hidden setting designed for developers that forces all installed applications to be resizable, regardless of whether the app publisher officially supports split-screen mode.
Go to your device 'Settings', scroll down to 'About phone', tap on 'Software information', and rapidly tap the 'Build number' seven times until Developer Options are enabled.
Return to the main 'Settings' menu, scroll to the bottom, and open 'Developer options'.
Scroll down to the 'Apps' section within Developer options and toggle the switch for 'Force activities to be resizable' to the ON position.
Reboot your Android phone to apply the changes, then try opening Adobe Acrobat in multi-window mode again.

Clear App Cache and Relaunch
Clearing the app's temporary data can resolve temporary glitches preventing the app from rendering correctly in split-screen mode.
Read PDFs in Split-Screen Seamlessly with WPS Office
If Adobe Acrobat continues to block multi-window functionality, WPS Office provides excellent native support for Android's split-screen mode. This allows you to effortlessly read and edit PDFs while taking notes, browsing, or chatting without any app restrictions.
- 1. Install WPS Office: Download and install WPS Office from the Google Play Store on your Android device.
- 2. Open Your PDF Document: Launch WPS Office and open your desired PDF file from your device storage or cloud drive.
- 3. Activate Split-Screen: Tap your device's recent apps button, tap the WPS Office app icon, and select 'Open in split screen view'.
- 4. Select Secondary App: Choose the second application you wish to use alongside your PDF for uninterrupted multitasking.

Frequently Asked Questions
Why does an Android app say it is not available in multi-window mode?
App developers must explicitly declare support for multi-window rendering in their application's code. If the developer has disabled this feature, or if the app's current version has a rendering bug, Android will display a restriction message when you try to force it into split-screen.
Can I open two PDF files side-by-side on an Android phone?
Yes, but it depends on your PDF reader. Apps with strong multitasking support, like WPS Office, allow you to use split-screen mode effectively, and some Android devices allow opening multiple instances of supported apps side-by-side.
How do I activate split-screen mode on a Samsung Galaxy device?
Swipe up from the bottom of your screen to open the Recent Apps menu. Tap the icon of the app you want to use at the top of its preview card, then select 'Open in split screen view'. Finally, tap another app to fill the bottom half of the screen.
