- Product
- Adobe Acrobat Android App
- Device & OS
- Android
- Scenario
- Filling out fillable PDF forms or adding an electronic signature on a mobile device.
- Observed behavior
- The Adobe Acrobat application unexpectedly crashes and closes during the form-filling or signing process.
Before attempting to uninstall or troubleshoot the app, ensure you back up your locally stored PDF files to a cloud service or a safe device folder, as uninstalling the application may permanently delete them.
Use the Dedicated Adobe Fill & Sign App
Since the main Acrobat app may experience stability issues with certain forms on Android, using Adobe's dedicated Fill & Sign app is the most reliable workaround.
Adobe provides a standalone application specifically optimized for completing forms and adding signatures. This app is generally more lightweight and handles complex form rendering better on Android devices, bypassing the crash issues found in the main reader app.
Open the Google Play Store on your Android device, search for 'Adobe Fill & Sign', and install the application.
Launch the Adobe Fill & Sign app, tap the '+' icon to select the PDF file you were trying to edit, and open it.
Tap anywhere on the document to add text or select the signature icon to insert your electronic signature without experiencing crashes.

Reinstall the Adobe Acrobat Application
If you prefer using a single app for all your PDF needs, a clean reinstallation can often resolve underlying bugs causing the app to crash.

Frequently Asked Questions
Why does my PDF app crash when I tap a signature field?
This typically happens due to memory management issues on Android or rendering bugs within the app's signature module. Large files or complex encrypted forms can overwhelm the app, causing it to close unexpectedly.
Will I lose my downloaded PDFs if I uninstall Adobe Acrobat on Android?
Yes, if the files are saved within the app's specific local directory rather than the device's global storage. Always back up your documents to a cloud service or your main 'Downloads' folder before uninstalling.
Can I use WPS Office to sign PDFs on my phone?
Absolutely. WPS Office features a comprehensive built-in PDF toolkit that includes robust Fill & Sign capabilities, allowing you to quickly and securely sign documents on your mobile device.
How do I safely save a backup of my PDF forms on Android?
Open your PDF app, choose the 'Save a Copy' or 'Share' option, and upload the document directly to a reliable cloud storage service like Google Drive, Dropbox, or OneDrive to ensure it is safely backed up.
