A small OTA update looks to be headed out to the Nexus 4 today, courtesy of an update document posted on T-Mobile's support page for the device. The build number is JWR66Y, which is obviously a very, very incremental bump from the previous build JWR66V. And the changelog matches up with such an assessment, as it includes but one item: "Security." That's nice and specific.


We have to assume this update will be headed to all Play Store Nexus 4 devices as well, not merely T-Mobile's, as the two are actually one and the same.

This does not appear to be the big 4.3.1 bug fix release that will inevitably come at some point, but merely a small security patch likely intended to fix some relatively newly-discovered exploits in Android. That said, we've not personally downloaded the OTA, so who knows what could be hiding in there? If you've received the JWR66Y OTA on your Play Store or otherwise non-T-Mobile Nexus 4, let us know in the comments.

    Found something related to this in Chromium bug tracker:

      Yes, it is reasonable to assume that when T-Mobile publishes a Nexus device's build number that said build number probably exists and has been subject to testing on devices.

    This only for the phones what T-Mobile is selling or everybody who uses the Nexus 4 with T-Mobile SIM?

      It shouldn't matter.

    I wonder if play store nexus buyers will have to wait for this patch until 4.3.1. It's known that many bugs are fixed and hold for future releases, which is really annoying. Anyway, let's hope this fixes reach AOSP at least.

      The Play Store phone is identical to the T Mobile phone, if one gets it, the other will.

    I'm running a Play Store N4 on T-mobile. So I guess I'm covered either way.

    Frankly I'll wait for Google to push an OTA to me rather than jump on a TMo patch. As much as I love TMo, until someone unpacks it to see what really is lurking in there, I'd rather keep my device plain vanilla.

    • Joe Hartley

      This is an OTA from Google, not from T-Mobile.

      • iandouglas

        then why is TMobile pushing it? shouldn't Google push it themselves?

        • sts115

          Google is pushing it, if you go to Tmo's page "link above" it clearly states that the update comes from Google. The fact that Tmo is describing what the update is, rather than Google does not necessitate that is's from Tmo.

    There's a thread about this update on XDA, apparently they fixed the random number generator bug (bitcoin issue) and system/keyboard freezes, both issues are flagged as "resolved" on the bug tracker.


  • ddpacino

    How can I force the update again?? Can't believe I forget this everytime, lol.

    It's been a good week though, with all of the updates from Google. Good works!
