Question details
The user is unable to open a downloaded PDF email attachment on their Samsung device using Adobe Acrobat, encountering a file type compatibility error.

- Product
- Adobe Acrobat for Android
- Device & OS
- Android (Samsung)
- Scenario
- Opening a PDF attachment that was downloaded directly from an email application.
- Observed behavior
- The device displays an error message stating 'There is no application on the device that can open this file type.'
Ensure that your Samsung device has a stable internet connection and that the PDF email attachment has completely finished downloading before you attempt to open it.
Update Adobe Acrobat and Android OS
Outdated applications or operating systems can cause file association errors. Updating ensures compatibility between the app and the PDF format.
Software updates frequently contain bug fixes for file handling. Verifying that both Adobe Acrobat and your Samsung device are running the latest versions is the most effective first step.
Open the Google Play Store on your Samsung device, tap your profile icon, select 'Manage apps & device', and check if an update is available for Adobe Acrobat.
If an update is listed, tap 'Update' next to Adobe Acrobat and wait for the installation to complete.
Navigate to your device 'Settings', scroll down to 'Software update', and tap 'Download and install' to ensure your Android OS is fully updated.

Isolate the PDF Source and File Integrity
Determine whether the issue is caused by a corrupted specific file or a system-wide application failure.
Reset Default App Associations
Clearing the default app settings forces the Android system to re-prompt you to select a PDF viewer, resolving misconfigured file handling.
Open PDF Email Attachments Easily with WPS Office
Bypass Android file association errors by setting WPS Office as your default PDF reader on your Samsung device. WPS Office provides a reliable, all-in-one suite to easily view, edit, and annotate PDF files without compatibility issues.
- 1. Install WPS Office: Download and install WPS Office for free from the Google Play Store on your Samsung device.
- 2. Save the PDF Attachment: Open your email application and save the problematic PDF attachment to your device's local storage.
- 3. Open with WPS: Navigate to your 'My Files' app, tap the downloaded PDF, and select 'WPS Office' from the 'Open with' menu.
- 4. Set as Default: Tap 'Always' when prompted to make WPS Office your default, error-free PDF reader for future email attachments.

Frequently Asked Questions
Why does my Samsung phone say 'no application can open this file type' for a PDF?
This error occurs when the Android system cannot detect a default app associated with the PDF format, the currently assigned app is corrupted, or the PDF file extension was lost during the email download process.
How do I change the default PDF viewer on my Android device?
Go to Settings > Apps, find your current PDF reader, and select 'Clear defaults'. Then, open a PDF file from your file manager, and Android will prompt you to select a new default application.
Can a corrupted PDF cause opening errors on Android?
Yes. If a PDF attachment is partially downloaded or corrupted during the email transfer, the reader app may fail to recognize its format and trigger a compatibility error message.
How can I tell if the PDF file or the app is the problem?
Try opening a different PDF file from a different source. If the other PDF opens perfectly, the original file is likely corrupted. If all PDFs trigger the same error, the Adobe Acrobat app or Android settings need troubleshooting.
