    I see lots of threads here where people are trying to determine their Nexus 5's specifications based on serial numbers. I submit to you that it makes far mode sense to check your hardware version instead; even quite small changes made to the Nexus 4 were delineated by an update to the hardware version and I expect the same will hold true for the Nexus 5.

    To find your hardware version:

    a. Turn phone on, then long-press power button until menu appears. Tap Power Off.

    b. After phone has shut down, simultaneously press and hold both volume down and power buttons for a few seconds. Boot screen will appear. See "HW VERSION" in the list at the bottom of the screen. Mine is rev_11.

    c. Press the power button to boot the phone normally. DO NOT play with the volume buttons unless you want to risk accidentally wiping your phone.

    Thanks!

    I cannot find a reliable answer anywhere.

    This site Google modifies Nexus 5 design to resolve build quality flaws states that:

    serial numbers beginning 310k are the original models, while the 311k models are the second revision and the 312k models appear to the very latest versions.

    and

    An even more accurate way to get find out which version you have is to start up the bootloader and check your hardware revision number.... What your looking for is either REV_10 (October), REV_11 (November) or REV_12 (December)
    However my Nexus 5 (purchased within minutes of the initial US release) is rev_11 and has a serial number beginning with 03107. So, am I first or second generation? Who can say...

    The 310, 311, and 312 are the date the device was manufactured. The 3 is for 2013 and the 10, 11, and 12 are for Oct. Nov. and Dec.
    They have nothing to do with the hardware revision other than newer hardware revisions being on phones being released later so it would make it seem they are the hardware revision numbers.
