Solution 1Recommended

Use Samsung's Native Split-Screen Mode

Utilize the built-in multi-window feature on your Samsung Galaxy Tab S7+ to open two different apps or two instances of a supported PDF app side by side.

Samsung's One UI provides excellent multitasking tools. You can use the split-screen view to open two separate PDF readers (or one app that supports multiple instances) simultaneously.

Open your first PDF

Launch your preferred PDF reader app and open the first PDF document you want to view.

Access Recent Apps

Swipe up from the bottom of the screen and hold, or tap the Recent Apps button on your navigation bar to view all currently open applications.

Activate Split-Screen View

Tap the icon of the PDF app at the top of its preview card, then select 'Open in split screen view' from the dropdown menu.

Select the second PDF app

The first app will pin to one side of the screen. From the app list on the other side, select a second PDF reader app (or a file manager) and open your second PDF document.

Adjusting the split: You can drag the divider line in the middle of the screen to adjust the width of each PDF window according to your preference.

Solution 2

Open PDFs in Pop-up View

Use Samsung's Pop-up view feature to open multiple PDF files in resizable, floating windows over your desktop.

Frequently Asked Questions

Can I view the same PDF twice side by side?

Yes, but you will need to create a duplicate copy of the PDF file first. Once copied, open the original file in one window and the copied file in the second window using the split-screen method.

Why won't my PDF app open in split-screen on my tablet?

Some third-party apps do not support Android's multi-window feature by default. To bypass this, you can enable Developer Options on your tablet and toggle on 'Force activities to be resizable', then restart your device.

Does WPS Office support opening multiple tabs on Android?

Yes, WPS Office for Android allows you to open multiple documents simultaneously. You can easily switch between them using the tabs at the top of the interface, making comparison fast and efficient.
