The Samsung Galaxy S4 is a very popular phone and millions of units have already been sold. Buy as many of you know, not all these units have been manufactured or produced at the same time (duh). Some units are produced at a later time of the year.
Even though these devices are almost the same, Samsung sometimes improves the quality of displays or memory chips. So you want to know when your Galaxy S4 was produced, right? Fortunately, finding the manufacturing date is an easy process and can be done by everyone.
First of all, open the dialer and type this code:*#197328640#. This will bring you to the Service Mode page. There will be some options to choose from, but you need te select Version Info. After that, there will be two options: SW (Software) Version and HW (Hardware) Version. In this case we need HW Version. At the next page that shows up, select Read Cal Date. That is the option that will show you the manufacturing date of your Samsung Galaxy S4.
That’s it. When was your phone manufactured ? Leave a comment below.
