How to Find Out Manufacturing Date of Samsung Galaxy Device + Secret Codes

4

All mobile phones, made by any manufacturer, have some certain set of codes that are used for specific purposes. Most of these codes are not meant for common users, and really  they really are of not much importance to most of us. I still remember the good old days with Symbian phones when we used to dial codes like “*#7780#” and “*#0000#” for hard resetting the phone and bringing out phone info. While most of such codes are not for an average or even advanced users, some of them are really important and we should take them down for future use.

Here I will be listing some of the secret codes for the range of Samsung Galaxy devices. Please note that all the codes might not work with all devices. Codes like *#06# and *#1234# are common to all phones, regardless of the manufacturer but some are device, carrier and region specific.

Find Out Manufacturing Date of Samsung Galaxy Devices

The secret codes can be used for several purposes, such getting the info of your device, resetting call counter, manage connectivity and radio, getting battery data, software and hardware version, setting up touchscreen, testing some features, changing CSC codes, and lots more. Here is how you can check the manufacturing date of a Samsung Galaxy device. You can try other options too.

Open your phone’s dialer and type the following code: *#197328640#*. In case it does not work for you, try this one: *#*#197328640#*#* . This will open the Service Mode menu on your Galaxy device. Select the option N. 2, that is “Version Info”. On the next screen, select ‘HW Version” (here HW means hardware). Now you will see another set of options on the next screen. Now tap on “Read CAL Date”, and bingo! You can now see the date of manufacture of your phone. In my case, it was August 21, 2012, as you can see in the screenshot above.

There is another way you can know the basic info about your phone through the IMEI (International Mobile Station Equipment Identity) number. Open dialer and type *#06# to get your phone’s IMEI number and type in the box at this site.
