How you know your samsung mobile manufacture date?

You can find the manufacture date of your Samsung mobile device by checking the device's settings or by looking at the original packaging. In the settings, go to "About phone" and look for the "Build number" or "Software information," which may include the manufacture date. Alternatively, you can use the IMEI number by entering it into an online IMEI checker, which often provides detailed information about the device, including its manufacture date.
