Search for Updates

Tap your profile icon, select 'Manage apps and device', and look for Adobe Acrobat under the 'Updates available' section.

Install and Restart

Tap 'Update' next to the Acrobat app. Once the update is installed, restart your Android device completely.

Retry Combining Photos

Open the updated Acrobat app and attempt to combine your photos into a PDF again to see if the process completes successfully.

Update Verification: Keeping your app up-to-date ensures seamless compatibility with the latest Android system patches and enhanced security.

Frequently Asked Questions

Why does the mobile app fail to combine photos after a system update?

System updates can change how an operating system handles file permissions or memory allocation. If the app hasn't been optimized for the new system version, it may crash or fail to process large tasks like merging images. Updating the app usually resolves this.

Does the image format matter when creating a PDF?

Yes. Most PDF converters function best with standard formats like JPG, JPEG, and PNG. Using newer or proprietary formats like HEIC or RAW without converting them first might cause the combination process to fail.

What information should I provide to support if the PDF app keeps failing?

When reporting a bug, it is best to provide your device model, current operating system version (e.g., Android 13), the exact app version installed, and a screen recording showing the steps taken right before the failure occurs.
