It's that time again, boys and girls. Last week the LTE model of the new Nexus 7 got an over-the-air update to Android 4.3.1, which was build number JLS36I for that specific device. As usual, Google has posted the factory software image for end users to download and the driver binaries for developers to play with.

You can find them in the usual locations, right next to all the other current files for Nexus devices on the Factory Images and Binaries pages at Developers.Google.com. So far the LTE version of the Nexus 7 2013 are the only devices to be issued with the 4.3.1 update. It's less than 10MB for the over-the-air download and we still don't know exactly what's in it. It's possible that this update will only be release for the Nexus 7, especially considering that Android 4.4 is probably right around the corner. In any case, here's hoping the developers have fun with the new code.

Update: Peter in the comments section has the changelog. It's mostly bug fixes and other small tweaks, but it also seems to disable the native tethering function when an AT&T LTE SIM is inserted. Bad form, Google, bad form.

    "So far the WiFi and LTE versions of the Nexus 7 2013 are the only devices to be issued with the 4.3.1 update."

    Are you sure the WiFi Nexus 7 (2013) got the update? I thought it was limited to the LTE version only.

    • Andrew

      "Wifi & LTE" meaning the devices that have both Wifi and LTE.

    • Jeremiah Rice

      You're right - I skimmed the text on the developer page too quickly. Fixed.

  • Peter

    Assuming I did it correctly, here is the changelog from JLS36C to JLS36I from the android-4.3.1_r1 aosp push this morning (only debrazorg devices got this update so far):

      d107040 Disable AppOps for real
      :(
      Let's wait for 4.4 then.

      • Peter

        AppOps still seems to work on my N7 LTE with JLS36I. So i'm not sure what this change is all about.

      Not sure if I did it right, but here's the diff with more details. Waiting for Al Sutton to provide his super nicely formatted one.

    Even in an unlocked, carrier-independent device, carriers still get their fingers in the pie. Why would AT&T be OK with tethering on a Nexus 4 or Google Play Edition phone, but demand it be shut off on the Nexus 7? That makes no sense.

    • Peter

      Does tethering not work on your Nexus 7 LTE?

      It works fine on mine, although I have the non-us model (different radio bands or something). But the software is the same i thought.

      • http://randomphantasmagoria.com/ Shawn

        The software shuts off the tethering option if you have a SIM card from certain carriers. In the USA, tethering is enabled if you have a T-Mobile SIM in it. However, if you insert an AT&T or Verizon SIM, the ROM disables tethering.

        • Peter

          Wow, didn't know that. Thanks for the reply.

          I wonder if that's included in AOSP or if it's just something extra Google added in for the retail builds.

          • http://www.androidpolice.com/ Artem Russakovskii

            It's in AOSP since that's what all these changes Peter posted are parsed out of.

          • Simon Belmont

            So, do you think this is something we'll start seeing more of? Like on the Nexus 5, for example, since it'll support AT&T LTE bands.

            I know people will always find ways around it, but I kinda like knowing that native tethering is there for me if I ever need it in stock Android 4.3. on my phone (G'Nex). I'm on T-Mobile, though, so this should be moot for me.

          • http://www.androidpolice.com/ Artem Russakovskii

            I have no idea, but that's likely why they did it, so I'm thinking yes.

          • http://randomphantasmagoria.com/ Shawn

            Not sure. It's not disabled on the Google Play Edition phones and those support AT&T LTE. I wonder if they take issue with tablets only? I guess we'll find out soon.

        • JD

          Have you confirmed with a Verizon LTE SIM that the tethering option is disabled in JLS36I? The changelog only mentions disabling AT&T. How about JLS36C build? I'm sorry if I'm beating a dead horse here.

          • http://randomphantasmagoria.com/ Shawn

            I have not confirmed it with an actual SIM, but I seem to remember reading that it's disabled on Verizon as well. I fully admit I may have jumped the gun on that one, though. Can anyone verify that it works on Verizon with the latest JLS36I firmware?

          • denSMSgt

            Tethering works fine with VZW SIM. Completely bewildering it is with ATT SIM, when I can use the same SIM to tether with an iPad.

  • Zach Mauch

    I'm still looking for an answer to the question of if all the LTE drivers and binaries are present in AOSP.

  • Skeptic

    Have the factory images posted by google been altered? I am questioning the AT&T tethering and mobile hotspot defaults being set to off when they were set to on on my original os.
