+ Case 3: Zalo Unable to Quickly Scan QR Code: Typically, to log in to your Zalo account or search for Zalo accounts using QR codes, you need to hold the phone's camera steadily towards the code for 3-5 seconds for the system to successfully scan.

+ Case 4: Internal App Error: Errors originating from within Zalo can also cause this problem. Try clearing the app's cache to resolve this. Steps: Go to Settings -->Apps (App Management) -->Zalo -->Clear Data --> Clear Cache or choose Clear All Data to reset the app to its initial state.
+ Case 5: Phone Camera Malfunction: If your device's camera is unable to focus on images or objects, encountering Zalo QR code scanning issues is inevitable. Check by using your phone's camera function to capture an image or object in front of you. If it fails to focus, your camera has a problem.
