How to Fix PDF Comments Disappearing in Adobe Acrobat Android
Question details
The user is experiencing an intermittent issue where comments and highlighted text disappear from locally stored PDF files in Adobe Acrobat Reader for Android.
- Product
- Adobe Acrobat Reader for Android
- Device & OS
- Samsung Galaxy S20 (Android 13)
- Scenario
- Annotating and highlighting locally stored PDF documents on an Android mobile device.
- Observed behavior
- Annotations temporarily appear upon reopening the document but intermittently disappear the following day, despite new comments saving correctly.
Ensure you are logged into your Adobe account and have a stable internet connection, as uploading local files to cloud storage can help stabilize annotation saving.
Save and Sync Annotated PDFs to Cloud Storage
Uploading your locally stored PDF to cloud storage prevents local caching glitches from causing your annotations to disappear overnight.
Local storage on Android devices can sometimes aggressively clear application cache or struggle to overwrite large PDF files with minor annotation updates. Utilizing cloud storage forces the app to sync the final, fully annotated version of the document to a remote server.
Open your PDF document in Adobe Acrobat Reader and add multiple comments and highlights to verify the tools are working.
Tap the three-dot menu (More) in the top right corner and select 'Save to Document Cloud' or upload the file to another connected cloud service like Google Drive.
Close the Adobe Acrobat application entirely. Reopen the app, access the file directly from the cloud storage tab, and confirm that all comments and highlights remain intact.
Provide a Sample PDF for Official Support Investigation
If the problem is isolated to specific documents, providing a sample file to the developer can help them identify and fix the underlying bug.
Annotate PDFs Securely with WPS Office on Android
Avoid disappearing comments and lost highlights by utilizing WPS Office for Android. It offers robust PDF editing, reliable local saving, and seamless cloud synchronization to ensure your document annotations are always preserved.
- 1. Install WPS Office: Download and install the WPS Office app from the Google Play Store on your Android device.
- 2. Open your PDF: Launch WPS Office and open your locally stored PDF file directly from the app's file manager.
- 3. Add annotations: Tap the 'Tools' menu at the bottom, switch to the 'Annotation' tab, and use the highlight or comment tools.
- 4. Save securely: Tap the 'Save' icon. WPS Office will securely embed the annotations into the PDF, or you can opt to sync it to WPS Cloud for backup.
Frequently Asked Questions
Why do my PDF highlights disappear after saving on Android?
This usually happens due to app caching issues, saving to a read-only directory, or the mobile application failing to properly embed the new metadata layers into the local file architecture before closing.
How can I recover lost PDF comments?
Unfortunately, if the comments were not successfully embedded into the file or synced to a cloud server before the application closed, they cannot be recovered. You will need to re-add the annotations and ensure the file saves correctly.
Do PDF annotations sync across devices automatically?
Annotations only sync across devices if you save the document to a supported cloud service (such as Document Cloud, Google Drive, or WPS Cloud). Files saved exclusively to your device's local storage will not sync.
