As you may know, there are two concepts related to the "country":
1- What country the Note 3 has been made for. This info is related to CSC (region), and can be obtained by using some app, e.g my app Phone INFO
2- In what country the Note 3 was made. This info is related to the Samsung's factory location. I see some pictures of Note 3 that has a label "Made by Samsung" or more detailed likes "Made in COUNTRY by Samsung" (picture attached below). So interesting if we can know in which country our Note 3 was actually made.
Any clues? May be we can get this information from IMEI range, S/N range? Thanks for any suggestion.
