"79K is the date and assembly site code in YMS format (2017 Year, 9th Month , Malacca assembly Site )
The "G4" with the underline is the J-STD-609 e-cat "Green status" code :

The "A0TV" is the lot trace code.
The bottom stamps are tooling marks by assembly site. Meanings depend on the individual assembly site.
