Sony's latest and greatest is getting a little bit better today as an update for the Xperia Z2 begins making its way out to devices. The Z2 was already on Android 4.4 KitKat, so there's no change on that front. The update (version 17.1.A.2.55) does include a number of notable tweaks and improvements, though.


Here's the changelog for the new software build.

  • Improved camera performance & function with faster start time and better auto focus
  • Enhanced in-call audio with fine tuned noise cancellation
  • Improved FM radio function
  • Graphics improvements with smoother scrolling and image movement
  • Improved stability with the latest bug fixes and enhancements

No new phone is completely without bugs, so it's nice to see Sony taking care of business. As for when owners can expect to get the OTA... well, it varies. The Z2 hasn't been released in all regions yet, and it's not on any US carriers. So most owners shouldn't have to wait long.

    This is the best sony flagship so far but they need to work on their UI which isnt up to the mark.

    • Ibrahim Yusuf

      what on their UI isn't up to the mark?

      • mesmorino

        And what mark is it not up to?

      • Sourabh Sekhar

        The design,color choices,icons etc
        Plus they are notorious for their lightning quick software updates.They usually release another phone before they update their previous flagship.

        • ashish

          I love their UI. Light and sweet. I sold my nexus to buy z1 compact. And I love it. Yes quick software update would be a plus always

          • Sourabh Sekhar

            I would take Sense 6 over the Xperia UI anyday

        • Ibrahim Yusuf

          you mean because Sony chose a certain color palette, that their color choices are bad.
          I think you confused Sony with Samsung.
          btw on Sony devices with 4.3 and above you can change your Colors and buttons to get it up to the mark

          • RyanWhitwam

            C'mon. The icons are horrendous. Be serious.

          • Jephri

            Nova launcher, Lumos icon pack, done

          • [S]unjay Burn[s] Red

            Not at all. That is an opinion.

        • [S]unjay Burn[s] Red

          I like their UI just the way it is. Their UI is very similar to their early UI, not much has changed.

  • Nick

    They need to hurry up and sell this phone in the US, unlocked. This is the first non-Nexus phone I've wanted to buy.

    • jonathan3579

      I'll buy it day 1 if they offer a 32GB unlocked version. I am not a huge fan of 16GB phones even if I don't need all the storage.

      • Joshua Hill

        It has expandable storage, so you can add an extra 128Gb if you want.

        • jonathan3579

          Yeah, I know but I still want ample onboard storage as well. Plus with the whole KitKat SD card restrictions now, it (SD cards) becomes less appealing.

          • Raphael Martinez

            " I am not a huge fan of 16GB phones even if I don't need all the storage." get SD card if you by chance happen to need more. "no, i just want to complain about a problem that doesn't exist (stomps feet and walks away)"

          • jonathan3579

            Hey dick, clearly you missed the point. I don't care about fucking SD cards because I want more storage on my device.

          • Raphael Martinez

            but... the card will give you more storage in the device. I know, you just want to complain about something for no reason. It's ok. The internet is here to support you. Here, have a lollypop

          • jonathan3579

            Lol, you're obviously a SD card fanboy. The reality is after I went Nexus and converted to cloud storage, the only thing that matters is my phone's storage amount. Also, if you re-read what I wrote, I said I'd buy day 1 if they offer a larger storage option. That was not a complaint. Troll harder, bro.

          • lolwut

            Have fun wasting your money bro. See this is why more than 90% of the population is on debt and can't afford med care, they spend all the money and no saving. I'm proud of not owning a smart phone and will continue to do so.

          • Giles Peach

            Or just get a job that pays more money so you can have a phone and healthcare, and a house, and a car, and holidays to the beach etc etc... while at the same time saving for retirement and those unexpected events life throws at you.

          • Eashan

            Go for oneplus one then

  • yankeesusa

    Too bad most of their other phones are still on 4.3 or even 4.2. I got rid of my xperia z because of that. I loved the software and ui but when you pay full price now for a phone you expect it to be up to date.

    • Ibrahim Yusuf

      Xperia Z is on 4.4.2

      • yankeesusa

        So they say...

        • The Maverick

          i feel you man! i had a Z1 compact (1st non stock phone i've had in years), was on 4.3 end of jan, 4.4 was due soon apparently, but after using a nexus 4 with kitkat as my previous, (loved the transculent bars) i realised this isn't for me. sold it and bought a moto x instead.

          • yankeesusa

            The thing is, with a kitkat update the Xperia z would be amazing. My wife still likes her Xperia. She's not into all the updates. For now I gave up my note 2 for a nexus 5 to hold me off till my next phone.

  • ekh

    This would be nice... if I could BUY one!

    • someone755

      Here is where my money would be.
      IF I HAD SOME.
      Seriously, phones are getting overpriced.

  • DDD

    Nice to hear about phones with limited availability. The phone looks really nice but its a shame it can't compete with even the oldest phones. Something to do with being attainable.

    • Jephri

      What? Can't compete? Name one phone this thing doesn't kill in a head on head comparison

      • Mike Reid

        He seems to merely be lamenting limited availability.

      • Raphael Martinez

        It can be as great as it wants but what good is it if no one can actually buy it? I went to every site I can think of willing to spend up to $700 on one and nothing.

  • Chris Stubbs

    My Z1S seems to be dead in the water.

  • Fresh360

    I tech dream of the day a Z2 compact is released. That would be the perfect phone, the Z2 is great but it's just too tall for my liking.

    • sQueezedhe

      Not long, just gone through FCC.

  • Michael Romano

    Given Sony's level of expertise when it comes to Cameras, optics, etc, it's surprising to see the Z2 continue to struggle in the Camera department. Hopefully some of these fixes will resolve that.

    • Linh Nguyën

      Different deparments.

  • Andy

    The Xperia Z2 is a great phone in most respects. It has a very good
    camera and outlasts the competition without compromising the experience.
    However, it is a bit awkward to use at times and gets hotter than the
    other top phones when under strain.
    And if you have decided to become a proud owner of this device, perhaps you’re in the market for a solid and beautiful protection case as well.


  • scrum
