If your Android device is not recognizing or functioning when scanning a QR code, it might be due to the accessibility settings on your device. These settings control the behavior and functionality of various features on your Android device, including QR code scanning.
Step 1: Verify Accessibility Settings
First, check if the accessibility settings on your Android device are properly configured. To do this, go to the "Settings" menu and tap on "Accessibility."
In the accessibility settings menu, make sure that the "Switch Access," "TalkBack," or any similar accessibility features are turned off.
In some cases, having these accessibility features enabled can interfere with the functioning of the QR code scanning feature.
Step 2: Clear Cache and Data
If the QR code scanning is still not working after verifying the accessibility settings, you can try clearing the cache and data for the scanning app.
To do this, go to the "Settings" menu and tap on "Apps" or "Applications."
Find the QR code scanning app you are using and tap on it. Then, tap on "Storage" or "Storage & cache."
Finally, tap on "Clear cache" and "Clear data."
Note that clearing the data for the scanning app will also clear any previously scanned QR codes, so make sure to save any important codes before proceeding.
After clearing the cache and data, open the QR code scanning app again and try scanning the QR code to see if it is now functioning correctly.
If the QR code scanning still does not work, there may be other issues with your Android device or the QR code itself. Consider trying a different QR code scanning app or contacting the app developer or device manufacturer for further assistance.
Resetting QR Code Scanner App to Default Settings

Unlock your Android phone, then navigate to the Settings menu. You can usually find the Settings icon either on your home screen or in the app drawer.
Step 2: Find the Apps Section
Scroll down and look for the "Apps" or "Application Manager" option in the Settings menu. Tap on it to continue.
Step 3: Locate the QR Code Scanner App
In the Apps section, you will see a list of all the installed apps on your Android phone. Scroll through the list and find the QR code scanner app that is not functioning properly.
Step 4: Access App Settings
Tap on the QR code scanner app to access its settings. You may need to tap on "Storage" or "App Info" to find the app settings.
Step 5: Clear App Data and Cache
Once you are in the app settings, look for the "Clear Data" and "Clear Cache" buttons. Tap on each of them to clear the app's data and cache. This action will reset the app to its default settings.
