1.THE BIG QUESTION – What was the date on which my phone was manufactured ?

-Open your phone’s dialer and type the following code: *#197328640#.
-In case it does not work for you, try this one: *#*#197328640#*#* . (WELL I DIDNT GET SUCCESS IN IT :laugh
-This will open the Service Mode menu on your Galaxy Grand.
-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 20130128 i.e 28th january 2013 .
