Question details
The user is experiencing immediate app crashes when trying to open files or launch the Acrobat Reader app on iOS devices, which persists even after reinstalling the app and updating the operating system.
- Product
- Acrobat Reader Mobile
- Device & OS
- iOS and iPadOS
- Scenario
- Launching the Acrobat Reader mobile app or attempting to open a PDF file on an Apple mobile device.
- Observed behavior
- The app opens briefly and then unexpectedly closes before displaying any file or reaching the Home screen.
Ensure that your iPhone or iPad is connected to the internet so that the device can receive the latest background patch released by Adobe for this specific issue.
Apply the Official Adobe Fix via Device Restart
Adobe has released an official backend fix for this specific iOS and iPadOS crash. A simple device restart will apply the fix.
Since this was a known bug acknowledged by the development team, the fix was rolled out directly to affected devices without necessarily requiring a full manual app update from the App Store. Restarting your device refreshes the app's cache and applies the patch.
Swipe up from the bottom of your screen (or double-click the Home button on older models) to open the App Switcher, then swipe up on the Acrobat Reader app to close it completely.
Press and hold either volume button and the side button until the power-off slider appears. Drag the slider to turn off your iPhone or iPad. Wait 30 seconds, then press and hold the side button to turn it back on.
Locate the Acrobat Reader app on your home screen, launch it, and try opening your PDF file again.

Check for Manual Updates in the App Store
If the backend fix does not apply automatically, updating the application to the latest version manually can resolve residual crash issues.
Read and Edit PDFs Seamlessly with WPS Office
If your current PDF reader continues to crash or malfunction, WPS Office provides a stable, fully-featured alternative for opening, reading, and editing PDFs on your iPhone and iPad without interruptions.
- 1. Download WPS Office: Go to the App Store on your iPhone or iPad, search for WPS Office, and install the free app.
- 2. Launch the App: Open WPS Office and follow the quick initial setup to grant local file access.
- 3. Locate Your PDF: Tap the 'Files' tab at the bottom to browse the documents stored on your device or iCloud.

Will reinstalling the app fix the continuous crashing issue?
In this specific scenario, reinstalling the app or updating iOS did not resolve the problem initially. Users must wait for the official Adobe fix to deploy to their device and then restart their iPhone or iPad to apply it.
