Question details
Users experience text formatting errors when typing in multiline PDF form fields on Android tablets, where spaces and characters create unintended new lines.

- Product
- Adobe Acrobat Reader
- Device & OS
- Android
- Scenario
- Filling out multiline PDF form fields using an Android tablet.
- Observed behavior
- Each typed character appears on a separate line, and pressing the space bar functions as a Return key. The same form functions properly on iPads and desktop computers.
Check your current app version in your Android settings or the Google Play Store to confirm if you are running the affected build (version 17.2.173338).
Revert to an Earlier Stable Version
Downgrading the PDF reader app to a previous version resolves the multiline spacing bug on Android devices.
This specific formatting bug is associated with Adobe Acrobat Reader DC version 17.2.173338 for Android. Because the issue stems from the app's code rather than the PDF file itself, reverting to version 16.3.1-155226 restores proper form filling functionality.
Go to your Android device's Settings, tap on 'Apps' or 'App Management', select Adobe Acrobat Reader, and tap 'Uninstall'.
Find and download the APK file for version 16.3.1-155226 from a trusted Android APK archive website.
Open the downloaded APK file. If prompted, grant permission to 'Install unknown apps' for your browser or file manager, then proceed with the installation.
Open the Google Play Store, search for Adobe Acrobat Reader, tap the three-dot menu in the top right corner, and uncheck 'Enable auto-update' to prevent the buggy version from reinstalling.
