Solution 1Recommended

Change the Android Keyboard or Input Method

Since this bug frequently occurs due to compatibility conflicts between OneNote and the default system keyboard, switching to an alternative keyboard can instantly resolve the typing duplication.

Certain manufacturer default keyboards may not interact properly with OneNote's auto-capitalization or formatting features on Android. Changing the input method isolates whether the app or the keyboard is the root cause.

Install a new keyboard app

Open the Google Play Store and download an alternative keyboard application, such as Microsoft SwiftKey or Gboard.

Set the new default keyboard

Go to your Android device Settings, navigate to 'System' or 'General Management', select 'Language and input', and set the newly installed keyboard as your default on-screen keyboard.

Test alternative input methods

Open OneNote and begin typing a sentence to check if the issue is resolved. Alternatively, try using the handwriting input or voice dictation features to see if the duplication persists.

Change the Android Keyboard or Input Method

Isolating the issue: If the duplication stops after changing the keyboard, the issue lies with the previous keyboard app. If it continues, the issue is strictly within the OneNote app itself.

Solution 2

Update or Reinstall the OneNote App

Applying the latest patches or performing a clean installation of OneNote can fix localized bugs causing text input errors.

Solution 3

Report the Bug to Microsoft

If troubleshooting fails, reporting the specific device and keyboard combination to Microsoft helps them release an official patch.
