Camera Not Working or Black Screen - How to Fix It

If the camera shows a black screen or you see a permission denied message when trying to scan food, the fix is to grant camera access to Nutrify through your device settings.

Why the Camera Stops Working

Nutrify needs camera permission to scan food with AI. If permission is denied (or was never granted), the scan screen shows a black screen or a blocked state. This can happen if:

• You tapped "Don't Allow" during initial setup
• You revoked the permission later in device settings
• You restored your device or reinstalled the app

Fix on iPhone (iOS)

1. Open the Settings app on your iPhone
2. Scroll down and tap Nutrify
3. Tap Camera
4. Select Allow While Using App
5. Return to Nutrify and try scanning again

Alternatively:

1. Go to Settings > Privacy & Security > Camera
2. Find Nutrify in the list
3. Toggle the switch on

💡 After granting permission, force-close Nutrify and reopen it to make sure the camera initialises cleanly.

Fix on Android

1. Open the Settings app on your Android device
2. Tap Apps (or Application Manager)
3. Find and tap Nutrify
4. Tap Permissions
5. Tap Camera
6. Select Allow only while using the app
7. Return to Nutrify and try scanning again

On some Android devices, you can long-press the Nutrify app icon, tap App info, then Permissions.

Camera Still Shows Black After Granting Permission

If the camera is granted but still black:

• Force-close the app and reopen it
• Restart your device
• Check if another app (e.g. a video call) is currently using the camera - close it first
• Update Nutrify to the latest version from the App Store or Google Play

Scan Food Screen Freezes on Load

If the scan screen loads but freezes before the camera viewfinder appears, this is usually a network or loading issue, not a camera permission problem. See the related article: Food Scan Stuck Loading - What to Do.
