How to Fix Acrobat Reader Crashing on Launch After an iOS Update

Product: Adobe Acrobat Reader Mobile
Device & OS: iOS (iPhone XS)
Scenario: Launching the Acrobat Reader mobile application after a recent app or system software update.
Observed behavior: The application fails to open and forcefully crashes or closes automatically right after being launched.

Before you start

Verify your internet connection to ensure your App Store can fetch the latest updates, and make sure your device has at least 20% battery life before attempting a system restart.

Solution 1Recommended

Update iOS and the Acrobat Application

Updating both the operating system and the mobile app is the most effective way to resolve compatibility conflicts causing crashes.

System and app updates often contain crucial bug fixes. When an iOS update introduces new system architectures, older app versions may fail to execute properly, resulting in unexpected crashes.

Verify iOS Version

Open the Settings app on your iPhone XS, tap on 'General', and select 'About' to check your current iOS version.

Update iOS System

In Settings, navigate to 'General' and tap 'Software Update'. If an update is available, tap 'Download and Install'.

Update Acrobat Reader

Open the App Store, tap your profile icon at the top right, and scroll down to pending updates. Tap 'Update' next to Adobe Acrobat Reader if it is listed.

Restart the Device

Press and hold the side button and either volume button until the power-off slider appears. Drag the slider to turn off the iPhone. Wait 30 seconds, then press and hold the side button to turn it back on.

Re-check App Version: If the app successfully launches after updating, go to Profile > About Acrobat within the app to ensure you are running the latest build.

Solution 2

Gather Diagnostics for Adobe Support

If standard updates fail, gathering specific device logs and screen recordings will help support teams identify unique configuration issues.

Frequently Asked Questions

Why does Acrobat Reader crash immediately after I update my iPhone?

Crashes usually occur because the older app architecture conflicts with new system files introduced during the iOS update. Updating the app to the latest version usually patches these incompatibilities.

Will reinstalling the PDF app delete my downloaded files?

If your PDF files are saved strictly within the app's local storage rather than in iCloud or Adobe Document Cloud, uninstalling the app will delete those local files. It is best to back up your documents before attempting a fresh installation.

How do I check my app version if the app crashes on launch?

If you cannot open the app to check the version internally, go to iPhone Settings > General > iPhone Storage, find the app in the list, and tap on it. The app version number will be displayed directly under the app's name.
