Question details

The user is unable to add multiline comments in Adobe Acrobat Reader on Android because the app fails to recognize line breaks.

Fixing the Multiline Comments Issue in Acrobat Reader on Android

Product: Adobe Acrobat Reader
Device & OS: Android 5.0.2
Scenario: Adding text annotations or comments to a PDF document on an Android mobile device.
Observed behavior: Pressing the Enter key acts as a submission command, immediately closing the comment box and restricting the user to a single line of text.

Before you start

Before altering app settings, test a few different PDF files to confirm if the multiline comment issue is file-specific or happening across the entire app.

Solution 1Recommended

Restart Device and Update Acrobat Reader

Refreshing the Android operating system and ensuring you are on the latest app version often resolves keyboard mapping bugs.

Software glitches in specific builds of mobile PDF readers can cause keyboard inputs like the 'Enter' key to be misinterpreted as a 'Submit' command instead of a line break. Updating the app replaces buggy code with the latest bug fixes from the developer.

Restart Android

Hold down the power button on your Android device and select 'Restart' to clear system cache and temporary glitches.

Check for app updates

Open the Google Play Store on your device, tap your profile icon, and go to 'Manage apps & device'.

Update Acrobat Reader

Find Adobe Acrobat Reader in the list of available updates and tap 'Update'. Wait for the installation to finish.

Test the comments

Open a PDF document in the newly updated Acrobat Reader and attempt to add a comment using the Enter key to see if multiline text now works.

Restart Device and Update Acrobat Reader

System updates: Also check your Android settings for any pending OS updates, as older Android versions (like 5.0.2) may have inherent keyboard API compatibility issues with newer app builds.

Solution 2

Test Alternative Files and Clear App Cache

Corrupted specific PDF files or bloated app cache data can sometimes interfere with editing tools and keyboard inputs.

Frequently Asked Questions

Why does the Enter key close my text box on Android?

This usually happens due to a keyboard mapping glitch or a bug in a specific version of the app where the 'Return' or 'Enter' key is improperly registered as a 'Submit' command instead of a carriage return.

Is there a workaround to add multiline comments if the bug persists?

Yes, as a temporary workaround, you can type your multiline comment in a standard notepad app on your phone, copy the entire text, and paste it directly into the PDF comment box.

Are PDF comments added in mobile apps visible on desktop computers?

Yes, standard PDF comments and annotations are saved within the file metadata. As long as you save the document after commenting, they can be viewed in other compatible PDF readers on any device, including desktop computers.
