- Device & OS
- not provided
- Scenario
- Attempting to edit a PDF document using a mobile device.
- Observed behavior
- The application closes automatically upon initiating the editing feature, failing to save or apply any document changes.
Ensure your mobile device is fully updated and has sufficient free storage space, as low memory can cause resource-intensive apps to crash during document editing.
Gather Troubleshooting Info and Update the App
Collect specific version information and record the issue to help identify the root cause, and ensure the app is updated to the latest version.
Often, app crashes during editing are tied to specific software bugs that might already be patched in newer versions. Collecting version data is crucial if you need to contact the support team.
Open the Acrobat Reader Mobile app, tap on your 'Profile' icon, and select 'About Acrobat' to note the current version installed.
Go to your phone's main Settings menu, tap on 'General' or 'System', and select 'About Phone' to identify your operating system and version.
Use your device's built-in screen recording feature to capture the exact moment the app closes when you attempt to edit the PDF document.
Visit the App Store (iOS) or Google Play Store (Android), search for Acrobat Reader, and tap 'Update' if a newer version is available.

Clear App Cache and Force Stop
Clear temporary files that may have become corrupted and are causing the app to close unexpectedly.
Edit PDFs Smoothly on Mobile with WPS Office
If your current PDF reader keeps crashing, use the WPS Office mobile app to edit, annotate, and manage your PDF documents smoothly. It offers a highly stable environment for document editing on the go.
- 1. Install WPS Office: Download and install the WPS Office app from the App Store or Google Play Store.
- 2. Open Your PDF: Launch WPS Office, tap the '+' or 'Files' tab, and select the PDF document you want to edit.
- 3. Edit the Document: Tap 'Edit' in the top toolbar to access PDF editing tools. You can smoothly modify text, add images, or insert signatures.

Frequently Asked Questions
Why does my mobile PDF app crash only when I try to edit?
Editing requires significantly more memory and processing power than simply reading a document. If your device is low on available RAM or if a specific editing module in the app is bugged, it triggers a crash exactly when that feature is activated.
Will clearing the app cache delete my downloaded PDF files?
No, selecting 'Clear Cache' only removes temporary operational files used by the app. However, if you mistakenly tap 'Clear Data', it may delete local files saved internally by the app.
Can a very large PDF file cause the mobile app to close?
Yes, PDF files with high-resolution images, complex vector graphics, or hundreds of pages require massive memory allocation. Mobile devices with limited memory can struggle, causing the app to force-close to protect the device system.
How do I record my screen to capture the app crashing?
On iOS, swipe down to open the Control Center and tap the 'Screen Recording' icon. On Android, pull down the Quick Settings panel and tap 'Screen Record'. Reproduce the crash while recording, then stop the recording to save the video to your gallery.
