Question details
The user needs to resolve an issue where Adobe Acrobat Reader Mobile automatically closes without an error shortly after opening any PDF file on a tablet.

- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- not provided
- Scenario
- Attempting to open and view PDF documents on a mobile tablet device.
- Observed behavior
- The PDF file opens for a few seconds, after which the application abruptly closes without displaying an error message. Setting the app as default and reinstalling it did not resolve the issue.
Ensure that your PDF files are not corrupted by verifying they can be successfully opened on a different device or computer before troubleshooting the tablet application.
Clear App Cache and Update Acrobat Mobile
Clearing accumulated cache data and updating to the latest application version can resolve unexpected crashes caused by corrupted temporary files.
Mobile applications store temporary data to load files faster. When this cache becomes corrupted, it can cause the app to crash abruptly upon opening files.
Open your tablet's 'Settings' menu and navigate to the 'Apps' or 'Application Manager' section.
Scroll through your list of installed applications and tap on 'Adobe Acrobat'.
Select the 'Storage' or 'Storage & cache' option, then tap the 'Clear Cache' button to remove temporary files.
Open your device's App Store (Google Play Store or Apple App Store), search for Adobe Acrobat, and tap 'Update' if a newer version is available.
Restart your tablet and attempt to open a PDF file again to see if the issue is resolved.

Re-authenticate Account and Update Tablet OS
Syncing errors with your Adobe account or compatibility issues with an outdated operating system can lead to app instability.
Submit a Crash Report for Investigation
If the issue persists across all files after troubleshooting, sending a crash report helps developers identify and fix the bug in future updates.
Open and Read PDF Files Stably with WPS Office

Frequently Asked Questions
Why does my PDF app close by itself when opening a file?
This typically occurs due to a corrupted application cache, an outdated app version, or insufficient tablet memory (RAM) struggling to process large or complex PDF files.
Will reinstalling the PDF reader delete my saved files?
If your PDF documents are saved locally on your tablet's internal storage or synced to a cloud service, reinstalling the application will not delete them. However, any files saved exclusively within the app's local sandbox data might be lost.
How can I tell if the PDF file itself is causing the app to crash?
Try opening several different PDF files on your tablet. If only one specific file causes the crash, the file might be corrupted or contain complex graphical elements not supported by the mobile viewer.
