How to check Nexus 6 Manufacture Date
I am not 100% positive on this interpretation, however it seemed to coincide with the time I received this device, so that might be it! (1) Turn off phone. (2) Hold VOLUME DOWN while powering on device (3) Press VOLUME UP / DOWN until it reads "Barcode" (4) Press Lock button (5) Read the "Date" row, note it's in MM-DD-YYYY format To get out: (6) Press any VOLUME key (7) Use VOLUME UP / DOWN keys to select "Start" (8) Press Lock button I pre-ordered my International Nexus 6 from Google, the device says 12-09-2014 (9th Dec 2014), and I received my phone on the 19th December 2014. Hope this helps!
