[INFO] LG Nexus 4 Production Date and Place Identification

I have figured out how to identify the production date and place based on the serial number, found on the box. The S/N inside the phone doesn't have to do anything with the one, printed on the box! Also, don't mix SN with IMEI.

Production date is encoded in the first 3 positions (reading from left to right):
1st position defines YEAR: 0 - 2010, 1 - 2011, 2 - 2012, 3 - 2013 and so on
2rd and 3rd define MONTH: 01 - January, 02 - February, 03 - March, 04 - April, 05 - May, 06 - June, 07 - July, 08 - August, 09 - September, 10 - October, 11 - November, 12 - December

4th position defines county:
K - Korea, C - China, B - Brazil.

For example:
211KPBF****** (last 6 digits are hidden for privacy reasons):

So, 211 - 2012 November (11), K - Korea.

Hope, this helps!

P.S. Last 6 numbers of the serial number match the last 6 numbers of the IMEI. It is incremented by 1 with each newly produced unit.

I did some sampling on the LG database.
Retrieved some 1% of the data up from the 100000 mark.
Found some interesting things like holes in the sequence, date order not in line with imei order, list of buyers, etc.

So, they did produce at least 70K devices in October, 90K in November and 210K in December, still counting (just 16G devices).

Not bad, now as christmas orders are completed google and LG are really ramping up the production.

GB seems to decode as follows:
G - 16Gb (8 - 8Gb)
B- Black.

Ladies and gentlemen, we have just reached the millionth device!

(of course just judging by serial number, i.e. minus gaps)

ATURBK 302KPSL999998 20130205 TURKEY

Which means, IMEI prefix 35391805* is now officially complete and the next one will be started.
