Band 12 and VoLTE support coming to Nexus 6 this week?


Recently, Google announced that Android 5.1 was in the process of being released, bringing with it some improvements to performance as well as HD Voice calls on T-Mobile and Verizon. And, if @askdes’ Twitter account is anything to go by, Android 5.1 could be coming to the Nexus 6 this week, bringing with it a few more T-Mobile enhancements.

In a discussion with followers on the popular social network, Des states that VoLTE and 5.1 are coming to the Nexus 6 this week, and also that band 12 will be enabled.

This is pretty awesome news for Nexus 6 owners on T-Mobile, even if it feels a little late.

As for Wi-Fi calling, as you can see from the tweet near the top of this post, that’s still being developed and seemingly taking a lot of work between T-Mobile, Android, Motorola and Qualcomm to get it working, ready for public release. Of course, T-Mo stated that it would have Wi-Fi calling on all its devices by early 2015, a time-frame which has surely slipped by. Still, I’d rather it was worked on and released fully working than a temperamental software update.

Once band 12 has been activated on the Nexus 6, people in areas where it has been activated should start experiencing much better indoor coverage. T-Mobile 700MHz airwaves penetrate building walls much better than the more traditional 1700/2100 and 1900 bands and could make the difference between needing a signal booster at home, and not needing one at all. The list of areas with active 700MHz sites is growing, some of them already showing up on T-Mobile’s new coverage map. Others are being logged on an open user-created map.

    If I manually updated to the official nexus 6 ota for 5.1 from google will I be able to receive this update?

    • taron19119


      • jonathan3579

        Not true.

        • taron19119

          T-mobile said that its not going to be in this update

        • jonathan3579

          Uh no, Des said 5.1 is going out next week… 5.1 (the one that is going out NOW) is what enables VoLTE. Get your facts straight. I’m using VoLTE on my Nexus 6 right now. Do you even own the device or are you just talking for the sake of spreading your misinformation?

        • MKashi

          is there a confusion in the article between this week and last week? AFAIK, the 5.1 images were available last week, I installed the 5.1 stock thursday or friday last week.

        • jonathan3579

          I think it’s just the way it was worded. Either that or Des didn’t realize we already have the images because I and others are definitely using VoLTE. I can’t comment on Band 12 because I haven’t looked for it.

        • MKashi

          disregarding the warped sense of time, WiFi Calling is not in the 5.1 ROM, at least not in the one I have from late last week, VoLTE present, don’t have B12 here where I am to check.

        • jonathan3579

          Yep, that’s still in development. That hasn’t been released yet. :)

        • DW

          With the 5.1 update from the factory images, I have Band 12 working just fine on my N6.

        • jonathan3579

          Awesome, thanks for that! I hadn’t taken the time to check since I couldn’t come across it with my gf’s Note 4 despite the fact that deployment has supposedly completed here in Houston.

        • Dan

          YW! Unfortunately for me, the Band 12 tower is too far from work to have any affect inside at my desk. Outside, I receive Band 12. Inside, the local HSPA+ signal is crazy strong and it switches from LTE.

        • dontsh00tmesanta

          Was in Merced and Firebaugh, CA this weekend. B12 is on!

        • dontsh00tmesanta

          I think the actual OTA is being sent to phones this week. Not everyone wants to flash an OTA considering how annoying using adb to do so is and flashing factory images may be too much for most.

          I got my replacement n6 and immediately unlocked and flashed the 5.1 factory images.

          Don say dont get a nexus unless you know how to do this…..frak that people want updates and big screen.

        • digiblur

          You don’t use adb for factory images. People that have done know it uses fastboot.

        • dontsh00tmesanta

          Adb for ota zips

        • dontsh00tmesanta

          Regardless adb is used to flash ota zips now. Not everyone knows about fastboot

        • Paul Hansen

          Adb Sideload?

    • jonathan3579

      Yes, you’ll be able to. All Nexus 6 are using the same software. Period. (Except for a rumored software version for Verizon, but we all know how that goes…)

      • dontsh00tmesanta

        All N6 have the same ending in D while the VZ N6 ends in E……I wonder the difference

        • Paul Hansen

          Newer radio. As far as I can tell that’s it. Been running it for a few days now.

        • Paul Hansen

          Newer radio. As far as I can tell that’s it. Been running it for a few days now. Same kernel.

  • Nathan S.

    Just checked and nothing yet for my N6.

    • Paul Hansen

      You can Sideload it or flash the factory image if you want it early.

  • Kyle Thompson

    they mean well, but the promise for N6 wi-fi calling (even being generous) expired long ago. TMO keeps saying all their phones are wi-fi calling enabled, and i’m still not seeing it happening anytime soon on the N6. I’m glad they’re working on it, but companies are working on a flexible tempered glass protector for the N6 as well and that ain’t going anywhere either…at some point the promise is broken.

    • Peter Blood

      They were able to do it with iOS. So they started looking in Android codebase and said, “oh, s@#$(! what is going on in here??” Delays ensue.

  • digiblur

    My n6 with a Tmobile SIM was showing the VoLTE switch yesterday. Running 5.1 on it. Updated via the factory images from Google when they were posted.

  • zach

    will this update come with a silent feature??

  • dontsh00tmesanta

    Is this the same update as the ota posted last week? Also the same as the 5.1 factory images?

    • eAbyss

      Yes, just as it says in the article. 5.1 activates band 12.

  • Genecio

    Early=Jan 1-April 30, Mid= May 1-Aug 31, Late= Sep 1-Dec 31.

    • Carlos

      Q1 = Jan 1 until Mar 31 Q2 = Apr 1 until June 30, Q3 =July 1st Until Sep 30, Q4 = Oct 1st until Dec 31st. So it looks like they have 2 weeks to get wifi calling in, which they don’t. I’m used to these manufacturers promising things only to never get them done in time. I’d be surprise if we get it by the end of Q2.

  • scarfacemario

    For anyone interested Band 12 antennas are being installed in the Los Angeles, Huntington Park, Anaheim areas. Spoke with engineers and there deploying aggressively. He said some sites take 2 weeks until they are live

  • SuzieSunshine

    Does anyone know if the T-Mobile update for the Nexus 6 will differ from the 5.1 release directly from Google? I installed 5.1 on my phone over the weekend manually, interested to see if these updates are already included.

    • jonathan3579

      It’s the same one considering what was said. The 5.1 update from Google DID in fact activate Band 12 confirmed below by comments of users and VoLTE which I can personally vouch for. Now comes the waiting game on a later update for WiFi Calling.

    • eAbyss

      Why do people still not understand this?

      A Nexus update is a Nexus update is a Nexus update. They’re all the same and come directly from Google.

  • gmo8492

    Seems that every thing is coming along smoothly, but I wonder how they are going to implement wifi calling since it’s usually baked into the rom. If it’s not, then there could be an unofficial port made in a matter of weeks.

    • eAbyss

      WiFi calling is going to be baked directly into Android (probably v5.2). All WiFi calling on Android so far has only been carrier/manufacturer tweaks added to the ROM, Google is about to add the real thing.

  • UralBas

    WIFI calling is a must.

    • skywalkr2

      Only if it works.

  • Rob

    The stock developer image has VoLTE, I am using it now (just tested it to make sure). It also has massively improved WiFi performance – I clocked 126Mbps at the peak with an average of 115Mbps using 200MB test. It didn’t want to move much above 50 before the update. And 50k AnTuTu with encryption disabled. I’ll take it.

  • Rob

    Loving this update. WiFi is vastly improved too. 126Mbps was the peak (we have a 105Mbps cable line) doing a 200MB speed test with a 115 average whereas before it didn’t go much over 50 and I disabled encryption so I have a 50k AnTuTu now. Huge difference on the phone. Can’t believe silent still hasn’t been added though…

    • Aaron C

      My battery seems better as well. Definitely noticing an increase in speed and stability.

  • Jason Crumbley

    The update hasn’t fixed any of the bugs I was experiencing. It’s actually made my phone worse. If I leave wifi on overnight, when I wake up, both wifi and cell data are disconnected and there’s an ! next to both. Signal strength has gotten worse and I am constantly dropping off of LTE to HSPA or losing signal in places where I used to have it. I’ve also had problems with the phone completely locking up. The only way that I’ve been able to get passed it is to hold the power button down until the phone reboots.
    5.1 isn’t ready just like 5.0, and 5.0.1 weren’t.

    • eAbyss

      Jeeze. Stop complaining and do a factory data reset.

      • Jason Crumbley

        I did. It didn’t do anything. Maybe ask questions before making an ass out of yourself.

    • Paul Hansen

      Are you using the 95R radio or 98R?

      • nxtiak

        Where did 98R come from?

        • Paul Hansen

          The “E” 5.1 build.

    • Darwinski

      update your router firmware.

  • Paul Hansen

    VOLTE is part of the 5.1 update that is already available as of last week. Wifi calling however is not so i’m looking forward to that as I work in a giant steel structure.

  • Brian Ruple

    I submitted some screenshots of my T-Mobile Nexus 6 on T-mobile in Cleveland Ohio area showing that I was connected to Band12 with the latest Nexus 6 Modem/Radio. Band 12 / 700mhz has been activated for Nexus 6 with the 5.1 firmware.

    • Aaron C

      So this is a Google stock image feature (band 12) and not a T-Mobile “activation?” I just flashed the 5.1 update and was curious if there would be a separate T-Mobile firmware. Probably will be for the WiFi calling when that’s released, huh?

      • Brian Ruple

        Correct, the new Google stock 5.1 image unlocked band 12 for all nexus 6’s…at least in the USA

        • David VanHouse

          I have 5.1 with the latest radio and canot see Band 12 in Washington DC (one of the deployed cities)

  • MrProTechHD .

    another TMobile BS weren’t they going to release all the updates at once? now the wifi calling is being developed? Mother Fuckers

    • Darwinski

      Pretty sure they said all along it would be released in separate updates.

  • francob911 .

    Is there a website were we can see all the current and yet to be release phones that support s band 12?? All I know is that the avant ,note 4 , nexus 6 ,xperia z3.!?

    • a d00d

      ZMax is also B12; the same web showing the 700 MHz market maps also shows which devices have Band 12, including whether it’s turned on out of the box or not.

      I still to this day don’t understand T-Mobile USA’s disabling features only to activate them later: my SGH-T889 Galaxy Note II has its LTE radio disabled out of the box only to be activated by an update later, and now the Nexus 6 and Band-12 (the VoLTE issue is a true software update adding a feature and not just an activation). I just don’t get it. :(

      I’m also wondering what the problem with Wi-Fi calling is. My guess, from a programming / hardware standpoint, is that I read (don’t remember where) it runs inside the baseband DSP like VoLTE does rather than inside the main operating system, so that may have something to do with it since all these ARM SoC makers seem to be very reluctant to release basic information without a ridiculously tight NDA–and even then stuff is missing or badly documented (or so I’ve read elsewhere). Hmm…just thought of something: maybe the DSP is coupled tighter (via internal hardware lines) to the cellular radio than to the Wi-Fi / Bluetooth radio (which may be a totally separate ASIC or hardware block on the SoC)…just looked at the Qualcomm website at the 805 and (unlike most other ARM SoCs) the part is supposedly 100% Qualcomm’s (although they bought Atheros, so the Wi-Fi / Bluetooth may really be an Atheros design, which in turn strongly implies they’re totally separate.

      Also just tripping over the “Quick Charge” that the specs say is integrated into the SoC! I didn’t know that, and it’s trippy. The die size must be HUGE–anyone know how big it is?

  • skywalkr2

    Based on this story I spent a lot of time upgrading/factory resetting my Nexus 6 last night. Wow. It feels like a completely different device now. I didn’t realize how sluggish it was before.

  • Ali Ali

    If I flashed the 5.1 google factory image on my t-mobile nexus 6, will I get the update?

  • dontsh00tmesanta
  • Carl

    I honestly don’t see much difference with Band 12 on my Note 4. Still having issues inside buildings.
