You are standing in the grocery aisle, ready to scan a product to track your calories, only to find the MyFitnessPal barcode scanner is not responding. The camera will not open, the button does nothing, or you see an error message stating a Premium subscription is required. You are not alone. Thousands of users report the MyFitnessPal barcode scanner not working, and the fix is not always obvious.
This guide covers the five core causes of this issue: a missing or inactive Premium subscription, denied camera permissions, an outdated app version, poor internet connection, or corrupted app data. We will walk through step-by-step solutions to get your scanner back online, whether you are on iPhone or Android.
Confirm Premium Subscription Status
As of October 1, 2022, MyFitnessPal restricts barcode scanning to Premium subscribers only. If you are on the free plan, the scanner simply will not work. There is no workaround. Even if you are on a free trial, any glitch in activation can block access.
Check If Your Premium Plan Is Active
The most common reason the scanner fails is an inactive or unrecognized subscription. Users often assume they are covered during a trial, but backend sync issues can prevent the app from recognizing access.
To verify your status, open MyFitnessPal and tap your profile icon. Go to Account Settings, then Subscription. Check if your plan shows as Active or Trial. If it says Free, you do not have access and will need to upgrade.
Warning: Some users report being charged but still locked out. This usually means the subscription is not properly linked to the app. Log out, restart the app, and log back in to force a sync.
Resolve Trial Activation Issues
If you signed up for a trial but cannot scan, wait 10 to 15 minutes after signup. Some delays occur during backend processing. Ensure you completed all verification steps, including email confirmation and payment method validation. Try canceling and re-enrolling in the trial if the status does not update.
Pro Tip: Use the web version at myfitnesspal.com to check your subscription. It is more accurate than the app in some cases.
Enable Camera Permissions
No camera access means no scanning. If MyFitnessPal cannot use your phone camera, the scanner either shows a black screen, crashes, or does not launch at all. This is especially common after app updates or OS upgrades, which sometimes reset permissions.
Grant Camera Access on iPhone
Open Settings and scroll to Privacy and Security. Tap Camera, then find MyFitnessPal in the list. Toggle it ON. After enabling, restart the app. Do not skip this step. iOS often requires a restart to apply permission changes.
Allow Camera Permissions on Android
Go to Settings, then Apps, and select MyFitnessPal. Tap Permissions and set Camera to Allow. Also check Microphone and Storage permissions, as some scanning functions use these. After enabling permissions, open the app and tap the scanner. You should see a prompt asking for camera access. Tap Allow.
If the permission toggle is grayed out or will not turn on, clear the app cache or reinstall the app as a last resort.
Update the MyFitnessPal App
An outdated app version is a frequent culprit behind scanner failures. Older builds may lack fixes for camera compatibility, security patches, or API changes that affect barcode lookup.
Update on iPhone
Open the App Store and tap your profile icon at the top. Scroll to find MyFitnessPal. Tap Update if available. After updating, completely close the app and reopen it. Do not just reopen it from the background.
Update on Android
Open the Google Play Store and tap Manage apps and device. Under Updates available, find MyFitnessPal. Tap Update. After installation, restart the app completely.
Pro Tip: Enable automatic updates to prevent future issues. On iOS, go to Settings, then App Store, and toggle on App Updates. On Android, go to Play Store, tap your profile, select Settings, and toggle on Auto-update apps.
Clear App Cache on Android
Corrupted temporary files can break specific features like the barcode scanner, even if everything else in the app works fine. Clearing the cache removes these files without deleting your food logs or account data.
Steps to Clear Cache
Open Settings on your Android device. Go to Apps, then MyFitnessPal. Tap Storage and select Clear Cache. Do not tap Clear Data, as this erases unsynced entries and logs you out.
After clearing, restart your phone. Reopen MyFitnessPal and test the scanner. The app may take slightly longer to load after a cache clear. That is normal. If the scanner works now, corrupted files were likely the issue.
Ensure Stable Internet Connection
The barcode scanner needs to connect to MyFitnessPal database to retrieve nutrition info. Without internet, it cannot process the scan, even if the camera works perfectly.
Test Different Connections
Try scanning using Wi-Fi first. Then turn off Wi-Fi and switch to mobile data. If one works and the other does not, the issue is connection-specific. Weak signal with only 1 to 2 bars often causes timeouts. Move closer to your router or step outside for better reception.
Confirm Internet Access
Test with another app before blaming MyFitnessPal. Open a browser and load a webpage, or use a social media app to refresh your feed. If other apps fail, the problem is your network, not the app.
Pro Tip: The scanner may work for previously scanned items offline, but new scans require live internet.
Reinstall MyFitnessPal App
When all else fails, reinstalling the app resolves deep software conflicts, corrupted installs, or sync errors that prevent scanner access, even with a valid subscription.
Sync Data Before Uninstalling
Critical step: Ensure your recent logs are saved online first. Open MyFitnessPal and pull down on the diary screen to force sync. Then visit myfitnesspal.com on a browser and confirm your entries appear. Also, note your email and password, as you will need them to log back in.
Warning: Uninstalling without syncing can delete unsaved logs.
Reinstall Process
Uninstall MyFitnessPal from your device. Restart your phone to clear residual processes. Go to the App Store or Play Store and reinstall the latest version. Open the app and log in. Wait 2 to 3 minutes for full sync. Grant camera permission when prompted. Test the scanner immediately.
Multiple users report this fix resolves persistent black screen or unresponsive button issues.
Check for Service Outages
Sometimes the problem is not your device. It is MyFitnessPal servers. Platform-wide outages can disable the scanner for all users, regardless of settings.
Where to Verify Status
Visit the MyFitnessPal Help Center at myfitnesspal.zendesk.com/hc/en-us. Check the Announcements page for Known Issues or Service Status. These pages list ongoing problems like scanner API failures, database lookup delays, and regional outages.
If multiple users report the same issue on forums or social media, wait 24 hours before further troubleshooting.
Fix Samsung and Android-Specific Issues
Some devices, especially Samsung Galaxy models like the S20, have extra layers of software that can block app features unexpectedly. One user reported the scanner button being unresponsive on a Samsung S20 despite having an active Premium trial and all permissions granted.
Disable Battery Optimization
Samsung aggressively manages battery usage, which can freeze background processes needed for scanning. Go to Settings, then Apps, then MyFitnessPal. Tap Battery and select Optimize battery usage. Find MyFitnessPal and set it to Do not optimize.
Check Device Care Settings
Open Device Care on your Samsung phone. Tap Battery, then App power management. Ensure MyFitnessPal is not restricted.
Rule Out Safe Mode
If your phone is in Safe Mode, third-party apps lose access to certain features. Restart your phone normally to exit Safe Mode. Look for Safe Mode in the corner of your screen. It should not be visible.
Pro Tip: After adjusting settings, reinstall the app to ensure full functionality.
Contact MyFitnessPal Support
If the scanner still will not work after trying all these steps, it is time to escalate. Support can check account-level issues, subscription sync problems, or device-specific bugs not visible to users.

Why is my barcode scanner not working even with Premium?
Even with Premium, issues can occur if your subscription status is not properly synced. Log out and log back in to force a sync. Also check that camera permissions are enabled and the app is updated.
Why does the scanner show a black screen?
A black screen usually means the app does not have camera permission. Go to your device settings and enable camera access for MyFitnessPal. Restart the app after granting permission.
Can I use the scanner offline?
The scanner requires internet to retrieve product nutrition data from MyFitnessPal database. Previously scanned items may be accessible offline if cached, but new scans need live internet.

Disable battery optimization for MyFitnessPal in your device settings. Check Device Care settings to ensure the app is not restricted. Try reinstalling the app if the issue persists.
