I am referring to an article (not in English) which teaches prospective buyers of the Galaxy Note 2 how to test the device they are about to pay for.
The article had a few points of what to check.
Main points of the article are: physically examine the GN2, pen detection, check what's included, try sim and most important (this is what I am asking for) is the Galaxy Note 2 system check. The test starts with keying a sequence which give you 18 buttons to check various functions of the GN2.
I am asking for an English version of the GN2 system check and how to read and understand some of the test results. The article does not explain much, just shows it (Google translation).
