You can also toggle Airplane Mode on and off on your Android device or toggle Airplane Mode on and off on your iPhone.

4. Restart your device. Restarting your mobile device will often clear most problems. So take a moment to reboot your Android or reboot your iOS device to see if it resolves problems with 3B Luna QR app not working.

Note: Why does a restart often help? When you restart your device, it clears out all the temporary files and working memory and loads up all the information the device and app(s) need. Sometimes these files have become temporarily corrupted and the only way to clear the corruption is with a restart.

5. Check for 3B Luna QR app updates. Check for and install any 3B Luna QR app updates on your Android device or app updates on your iPhone. If your 3B Luna QR app is ever out of date, it can lead to connection errors and other issues that may lead to 3B Luna QR not working on your mobile device.

6. Clear the 3B Luna QR app cache on your Android device or clear the cache on an iPhone. While caching improves app performance by saving app information in local memory, it can also lead to issues with your device not receiving the latest information from 3B Luna QR. Clearing cached data will force your app to retrieve the latest information from 3B Luna QR.

7. Check the 3B Luna QR app permissions. You need to give 3B Luna QR permission to access things like your contacts, photos, mic, etc., otherwise, those things won’t work.

If you can’t find the app on the Google Play store anymore, you may need to find and install the APK for it instead. You can also find the older version of app on iPhone as well.

9. Free-up space on your phone. A lack of free space can often cause apps to crash or not open.

10. Disable your VPN service. A VPN is a great service for protecting your privacy and increasing security. Unfortunately, a VPN can also cause connection errors and lead to 3B Luna QR not working. To test if this is the case, disable your VPN on Android device or disable your VPN on iPhone and check if this resolved the issue.

11. Make sure background data is not restricted. If Background data is turned off, 3B Luna QR may not be able to connect to the internet while it’s running in the background. To fix this, you need to turn on the background data on Android or turn on the background data on iPhone.

12. Reset your iPhone’s app settings or reset app settings on your Android device. This action does not delete any of your apps or their data. It reverts app-specific settings back to their default values. This can include preferences like notification settings, permissions, background app refresh settings, and other app-specific configurations.

13. Reset your phone’s network settings. If the 3B Luna QR app is having trouble connecting to the 3B Luna QR servers, performing a network settings reset on your Android device or network settings reset on your iPhone could fix it.
