To Check Manufacturing Date:​

Accessing Other Hidden Information:​

1. ##634#: This code, when entered into the dialer app, might open a hidden diagnostic app. It may offer some hardware-related information about the phone but won't typically display the manufacturing date.
2. ##3282#: This code may give you access to a field test tool with more detailed information about the device, including manufacturing details.
3. ##7820#: This code, if supported on your device, can provide information about the phone such as the manufacturer, device model, hardware version, firmware version, and more. Please note that these codes may or may not work on all Lumia devices or versions of Windows Phone. Also, be cautious when entering codes as some could have unintended consequences or may not work at all depending on your device's software version. It's always best to check the device's manual or contact the manufacturer's support for the most accurate and detailed information about your device. Important: Before entering any codes, ensure you have backed up your data, as some codes may reset your device or affect its functionality. Hope this helps you access hidden information about your Lumia 520! Let me know if you need further assistance. [Note: Some Nokia codes may also work on devices under the Microsoft Lumia brand, but results may vary based on the device model and software version]
