A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Perform the following steps on the Android phone to restore OneNote functionality after the OS/One UI update:
- Update OneNote from the Play Store
- Open Play Store.
- Tap the menu button (top left) → My apps & games.
- Find OneNote and tap Update if available.
This ensures compatibility with the latest Android/One UI version.
- Force stop and relaunch OneNote
- Go to Settings → Applications → Application Manager → OneNote.
- Tap Force Stop.
- Reopen OneNote from the app drawer.
- Check for account/sign-in issues
If OneNote opens but does not sync or shows an account error (for example, messages like “To sync this notebook, sign in to OneNote” or Account Error – Action Required):- In Android Settings → Accounts, verify the account used with OneNote (phone-number-based accounts may require an email).
- When prompted in OneNote, tap Add Email and add a valid email address to continue syncing.
- Reinstall OneNote (if it still does not open)
- Uninstall OneNote from the device.
- Open Play Store and install Microsoft OneNote for Android again using the official listing.
- Open OneNote and sign in with the Microsoft account used previously so notebooks can resync from the cloud.
If OneNote continues to fail to open even after updating and reinstalling, collect details (device model, exact error behavior) and report the issue via the OneNote for Android support channels or community forums so the product team can investigate.
