Hi Tania Moysey
Thank you for reaching out to Microsoft Q&A Forum and sharing your experience.
On Android devices, including Samsung Galaxy tablets, offline availability works differently compared to iOS.
In the SharePoint mobile app for Android, there is currently no option to make an entire document library or folder available offline. Only individual files can be marked for offline access. In this case, syncing SharePoint content through the OneDrive app is the recommended workaround.
With the OneDrive app on Android, you may be able to make entire folders from a SharePoint document library available offline. To do this, install the Microsoft OneDrive app and sign in using your work or school account associated with Microsoft 365. After signing in, locate the SharePoint document library linked to your site. If the library does not appear immediately, open it in SharePoint via a desktop browser and confirm it is available in OneDrive.
Once the library is visible in the OneDrive Android app, navigate to the required folder, tap the three‑dot (⋮) menu, and select Make available offline. Allow time for the sync to complete before disconnecting from the network.
