- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- Samsung S7 Plus (Android)
- Scenario
- Attempting to open PDF documents on an Android tablet using the Adobe Acrobat Reader application.
- Observed behavior
- The application suddenly stops loading or fails to open documents that are fully supported and previously worked without issues.
Verify that your Samsung S7 Plus has a stable internet connection if you are trying to open cloud-hosted documents, and ensure the specific PDF files are not corrupted by testing them on another device or application first.
Clear App Cache and Restart Device
Clearing accumulated app cache can resolve sudden app freezes, crashes, or document loading failures on Android devices.
Temporary files stored by the app can sometimes become corrupted, leading to sudden malfunctions. Clearing the cache is a safe procedure that will not delete your actual PDF files.
Navigate to the main Settings app on your Samsung S7 Plus tablet.
Scroll down and tap on 'Apps' to view the list of all installed applications on your device.
Find and select 'Adobe Acrobat' from the application list.
Tap on 'Storage', then select 'Clear cache' at the bottom of the screen. If the issue persists later, you can return here and try 'Clear data' (note that clearing data resets the app's login and preferences).
Press and hold the power button to restart your Samsung S7 Plus, then open the app and try viewing the document again.

Update or Reinstall the Application
Running an outdated version of the app may cause compatibility issues with the latest Android system updates on your tablet.
Open Your PDF Documents Instantly with WPS Office
If your current PDF reader continues to crash or fail on your Samsung S7 Plus, you can seamlessly open, read, and edit your PDF files using WPS Office. It provides a lightweight, highly optimized reading experience for Android tablets.
- 1. Download WPS Office: Install WPS Office for free from the Google Play Store on your Samsung S7 Plus.
- 2. Locate Your PDF: Open WPS Office, tap on the 'Files' tab at the bottom, and navigate to 'Document' or the specific folder where your PDF is saved.
- 3. Open and Read: Tap on the PDF file to open it instantly. You can now read, annotate, or share the document without experiencing crashes.

Frequently Asked Questions
Why did my PDF reader suddenly stop opening files on my Android tablet?
App caches can become corrupted over time, or a recent Android OS update on your Samsung tablet might have caused temporary compatibility bugs with your currently installed version of the reader application.
Will clearing the app data delete my downloaded PDF files?
No, clearing the app data for a PDF reader only resets the application's internal settings, preferences, and login information. Your downloaded PDF documents remain safe in your device's local storage.
How do I know if my PDF file itself is corrupted?
You can test the document by transferring it to another device, such as a laptop or smartphone, or by attempting to open it with a different PDF viewer like WPS Office. If the file fails to open in all applications, the file itself is likely corrupted and needs to be downloaded again.
