Users experience unexpected app crashes in Adobe Fill & Sign on Android devices when attempting to move a signature or initials on a PDF document.

How to Fix Adobe Fill & Sign Crashing When Moving Signatures on Android

Product: Adobe Fill & Sign
Device & OS: Android 9 (Google Pixel devices)
Scenario: Attempting to sign a PDF document and repositioning the placed signature or initials by dragging it across the page.
Observed behavior: The application immediately crashes and closes unexpectedly when dragging the signature, although placing and resizing the signature works normally.

Before you start

Ensure your Android operating system and the Adobe Fill & Sign app are updated to the latest available versions, as app crashes are frequently resolved through minor developer patches.

Solution 1Recommended

Clear App Cache and Update Software

Resolves temporary glitches and compatibility issues introduced by corrupted cached data or outdated app versions.

Software crashes during specific touch gestures are often caused by conflicting cache data or an unpatched bug. Clearing the cache refreshes the app without deleting your documents.

Open Android Settings

Go to your Android device's 'Settings' and select 'Apps' or 'Apps & notifications' to view your installed applications.

Locate Adobe Fill & Sign

Scroll through the app list or use the search bar to find and tap on 'Adobe Fill & Sign'.

Clear the App Cache

Tap on 'Storage & cache' and select 'Clear Cache'. Do not tap 'Clear Data' unless you have backed up your signed documents, as this will reset the app.

Update the App

Open the Google Play Store, search for Adobe Fill & Sign, and tap 'Update' if a new version is available.

Restart and Test

Restart your Android device, open your PDF, and attempt to move the signature again to see if the crash is resolved.

Device Compatibility: If you are running older Android versions like Android 9 (Pie), the issue might be a system-level compatibility bug that requires a specific patch from the app developers.

Solution 2

Switch to an Alternative PDF Signature Tool

Bypasses the application bug entirely by using a different, stable application to sign and manage your PDF documents.

Frequently Asked Questions

Why does Adobe Fill & Sign only crash when moving the signature?

This specific crash is typically caused by a touch-event handling bug or rendering conflict between the app's user interface and certain Android OS versions (like Android 9 Pie) during the drag-and-drop action.

Will clearing the app data delete my saved signatures?

Yes, clearing the app data or storage in Android settings will reset the app to its default state, which deletes your locally stored profiles, initials, and signatures. Clearing the 'Cache' is safer and usually does not delete this personal data.

Is the standalone Adobe Fill & Sign app being discontinued?

Adobe has increasingly integrated the Fill & Sign features directly into the main Adobe Acrobat Reader app. Users experiencing persistent bugs in the standalone app are often encouraged to switch to Acrobat Reader or robust alternatives like WPS Office.

How do I sign PDFs on Android without downloading standalone signature apps?

You can use an all-in-one office suite like WPS Office, which includes built-in PDF viewing and digital signing capabilities. This eliminates the need to install single-purpose signature apps that may have compatibility issues.
