Question details
The user wants to configure their Samsung smartphone to automatically open PDF documents using Adobe Acrobat.

- Product
- Adobe Acrobat
- Device & OS
- Android
- Scenario
- Opening downloaded or received PDF files on a Samsung mobile device.
- Observed behavior
- The Android system repeatedly prompts the user to choose an application each time they try to open a PDF file, rather than opening it automatically.
Ensure that Adobe Acrobat is installed on your Samsung phone and updated to the latest version via the Google Play Store.
Set Default via the 'Open With' Prompt
The fastest way to set a default app is directly from the system prompt when opening a file for the first time.
Android provides an built-in mechanism to assign default applications seamlessly when you access an unassigned file type.
Open the 'My Files' app on your Samsung phone and navigate to your Documents or Downloads folder to find a PDF file.
Tap on the PDF file. Since no default is set, a prompt will appear asking which app you want to use.
Tap on the 'Adobe Acrobat' icon from the list of available applications.
Tap the 'Always' button at the bottom of the prompt. All future PDF files will now automatically open in Adobe Acrobat.

Configure Default Apps in System Settings
Use your Samsung device's settings menu to manually manage and clear default application preferences.
Use WPS Office as Your Default PDF Viewer on Android
WPS Office offers a lightning-fast, lightweight, and feature-rich PDF viewer and editor. You can easily set it as your default PDF app to view, annotate, and manage PDFs seamlessly on your Samsung device.
- 1. Install WPS Office: Download and install the free WPS Office app from the Google Play Store.
- 2. Open a PDF Document: Navigate to your file manager and tap on any saved PDF file.
- 3. Select WPS Office: When the app selection menu appears, tap on the WPS Office icon.
- 4. Set as Default: Tap 'Always' to establish WPS Office as your permanent, default PDF reader.

Frequently Asked Questions
Why doesn't the 'Always' prompt appear when I open a PDF file?
Another application is likely already set as the default PDF viewer on your Samsung phone. You must go to Settings > Apps, find the app currently opening your PDFs, and tap 'Clear defaults' before you can choose a new default app.
Can I change my default PDF app back to Samsung Notes later?
Yes. You can navigate to Settings > Apps > Adobe Acrobat, select 'Set as default', and clear its defaults. The next time you open a PDF, the system will prompt you again, allowing you to select Samsung Notes and tap 'Always'.
Does setting a new default app modify or alter my existing PDF files?
No. Changing the default application only modifies the system's instruction on which software to use for reading the file. Your actual PDF documents remain entirely unmodified and safely stored on your device's memory.
