Question details

The user is unable to find the flash on/off toggle on the document-scanning screen within the OneDrive mobile application.

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Scanning a document using the 'Add and Scan' feature in the mobile app.
Observed behavior: The flash control icon is completely missing from the scanning interface, preventing the user from toggling the flashlight.

Before you start

Ensure your mobile device's physical flashlight is functioning properly by turning it on directly from your phone's quick settings menu.

Solution 1Recommended

Reinstall the OneDrive App and Update Your Device OS

Outdated app versions or temporary software glitches can cause UI elements like the flash control to disappear. Updating both the app and the OS resolves these bugs.

In many cases, interface glitches in mobile applications are tied to cached data errors or incompatibilities with older operating system versions. Starting fresh with the latest software patches usually restores missing features.

Uninstall the app

Go to your device's home screen or app drawer, long-press the OneDrive icon, and select 'Uninstall' or 'Remove App'.

Update your operating system

Navigate to your phone's Settings menu, tap on 'System' or 'General', select 'Software Update', and install any pending updates.

Reinstall OneDrive

Open the App Store (iOS) or Google Play Store (Android), search for Microsoft OneDrive, and download the latest available version.

Test the scanner

Launch OneDrive, sign in to your account, tap the 'Add' (+) button, select 'Scan', and verify if the flash control icon has reappeared on the screen.

Permission Check: Upon reinstalling, ensure you grant the app permission to access your camera, as the flash control relies on camera hardware integration.

Solution 2

Trigger the Auto-Flash Feature Manually

Some versions of OneDrive automatically hide the flash toggle if the app determines that the ambient lighting is more than sufficient for scanning.
