Xperia Z4 docomoNTT docomo is the first Japanese carrier to release the Sony Xperia Z4 (SO-03G), with the phone ready to pick up in stores or order online. NTT docomo announced a day-one firmware update for the device relating to a reduction in speaker volume under certain conditions. The new update moves the firmware build number from 28.0.B.0.446 to version 28.0.B.0.457. NTT docomo has priced the Xperia Z4 at 93,312 yen (£488, €669, $744). Other Japanese carriers will launch the Xperia Z4 over the next couple of days, with au releasing it tomorrow (11 June) and SoftBank releasing it on 12 June.

    They should also fix that on the z3

  • Abdul Ghani

    All who think qualcomm still rocks and suck its dick this is for them http://www.androidauthority.com/snapdragon-810-japanese-carrier-615732/ qualcomm fucked up really bad the best processor is now helio mediatek x10 and upcoming x20

  • Tim Rox Westerholm

    Is “that” the next gen Xperia Home or what? 0,0

  • Jonny Love

    Any chance they fix the speakers on the z3 too then. Been with Sony long time but camera has disappointed me and now speakers think might change ways next time and thought I’d never hear me say that

  • Tomislav Mati?

    I think this is NTT docomo launcher.

  • shhh

    Everyone knows they fucked up with the 810. But Sony can’t risk going for another SoC manufacturer for their flagship. They are a top tier customer for Qualcomm, and Qualcomm still has a chance to redeem their customers if they do good with the 820 and make it available ASAP. If Sony goes for MTK or even Exynos, they might lose their status as a top tier customer hence they will not be able to avail of their flagship SoCs as fast as the other OEMs especially that Sony is still going for a 6-month cycle. Samsung can do it because they have lots of money to offer to Qualcomm in case they want to come back and their Exynos is doing great.

  • Matt

    its really fun to see people who think you can just put a chiset in a phone, just like PC.and with 0 optimization . . .

    they have to plan the phone long before it hit the market . they cant just put it in there . .

  • Matt

    is there something wrong with z3 speaker? mine is fine . .

  • Jonny Love

    Yeah though think it’s software related related, music is ok, Netflix is very low even on full and live streaming on YouTube and BBC iplayer it’snon-existence. Just didn’t notice it when I first got phone but but bad lately

  • Abdul Ghani

    Ummm sony already making x10 mediatek phones lavender plus mediatek has better battery life no heating issues 480fps 1080p recording and many features supports 2k display in tests shown no lag in games smooth performance

  • shhh

    Don’t “ummm” me. Lavender is most likely a mid-range phone. I said they can’t go for other SoCs for their FLAGSHIP phones. And, since you obviously skimmed too much of what I said or you didn’t read it at all, they can’t risk their status as a top tier customer for Qualcomm. Tell their engineers and LG’s, HTC’s, Xiaomi’s and everyone else using a Snapdragon SoC why Mediatek’s SoC is better for their flagships.

  • Abdul Ghani

    Ummm what if 820 heats up ull suck that too and a company like sony risk again to install a overheating processor again just for people like u who likes snapdragons overheating dick….. it would be best to use x20 than 820 and x20 has extra features like I mentioned before

  • kaostheory

    That link doesn’t say anything or compare chipsets.

  • shhh

    Well obviously you’re an engineer who has been in the future and is here to warn us about how the 820 will fail. Go tell Kaz the news you bring from the future. It’s impossible to argue with you.

  • Matt

    well i dont know about netflix, but mine is fine streaming youtube . . .

    are you on 5.0.2?

  • Matt

    mate , a person who use the word quallcom and dick in the ssame sentence doesnt worth your time. just let him be . .

    he only read spreadsheet, and even not good at doing so. Or he might be 12 :P

  • Abdul Ghani

    Have u done research on x20 u faggot just a blind qualcomm fanboy as expected enjoy the lovely overheating phone

  • Abdul Ghani

    Ohhh u guys just talk without any research tests results qualcomm failed this gen but mediatek won easily thats why sony and htc built mediatek phones and htc e9+ is a flagship

  • Abdul Ghani

    12 lol What knowledge u have on processor and its features its tests results and its tech the way they perform seriously grow up infant

  • Jonny Love

    Am indeed, strange one as I have a note 4 and htc one and both fine with various apps. Wait out and see just if this update was anything similar to what I am experiencing

  • Sadman Khan

    The gaming performance of mediatek is still shit.

  • Timel

    Japanese people still love the Apple iPhone 6 Plus more this Sony phone

    Why?

  • Timel

    So interested

    I heard that Sony has a very good relationship with Mediatek, I also heard that Sony uses Mediatek chipsets with their Bravia 4K Smart TVs as well.

  • Because America.

  • Aca

    Sony, put some Intel processors in future Z smartphones

  • Aiden Pearce

    docomo custom launcher

  • Timel

    poor GPS signal also

  • Svnjay

    You really are a paid Apple shill, aren’t you?

  • sephiroth_4

    ~will this work on Verizon~ :P I need this phone now!

  • Ayad Fahos

    Can you sony fix z3 dual his working likeshit after update to lolipop sound is very low battery drain fast and some apps is missing

  • Timel

    Would you believe me if I said I’m a huge Sony fan?

  • Timel

    I think because Apple can make a better smartphone, Apple gives Japanese costumers a better user experience, a better software and better ecosystem, a better and smarter camera Apple also gives them a better after severice and better product warranty.

    Because even Japanese people still think that today Apple is better than Sony.

  • Svnjay

    Nope :)

  • Timel

    Up to you
    You’re very stupid -_-

  • Svnjay

    Thank you!

  • Timel

    Because that was the first time Apple entered the Chinese market, a little fact every Apple fan chooses to ignore, it’s why they returned record profits for the quarter, that tends to happen when you enter a humongous market for the first time.
    It just makes more:

    Because that is all you are! I mean Phil Schiller was interviewed and pulled out of his arse why it’s good for you the fact the iPhone starts with 16GB storage that they will not change and how it’s good for you that Apple chooses form over function by ditching usable battery life for thin designs.. Yeah Apple fans lap every piece of BS Apple feeds them.

  • 2sfhim

    J’adore cette couleur, simplement magnifique, sobre, différent et classe.

  • apolloa

    Yeah that’s the problem, Snapdragon and Andreno have great support, not even all games run on the Tegra chipsets! I would choose an SD chip over a MediaTek one because of this reason!

  • apolloa

    Will be looking forward to the benchmark tests of this 810 V2.1 chip, see if it throttles or if they fixed that problem. Will also be interesting to see what SOC the Xperia Z4 Compact has.

  • Timel

    Chinese market?
    What the fuck?

    Are you drunk?

  • Timel

    You mad?

    LOL so pity!

  • apolloa

    Edited to make better sense to you, but it was a true fact that is conveniently twisted by Apple trolls.

  • gamer324

    You are viewing this too narrowly, yes the mediatek chipsets are good this gen, but it is a tricluster system with one efficient quad core, one balance quadcore and a performance dual core, if this sounds complicated, that’s because it is.
    And then there’s the GPU issue, the helio p10 uses a quad core (mp4) T768 mali gpu, right off the bat this is half the gpu grunt as the Exynos 7420 ( which uses a T760 Mali gpu with 8 cores i.e. mp8), and the x20 lowers the parallelism even further to just two Powervr g6200 cores. This particular processor (g6200) is actually the entry level gpu in the PowerVR Rogue family, the apple A7 (yes the one in iphone 5s, not iphone 6) used a more beefier quad core model (G6430), so the g6200 is the entry level gpu of a two year old gpu family whose beefier quad core brother was used in the iphone 5s. My point is that both 10 core SoCs use at best upper mid range GPUs, yes they’ll power 2k hardware, but probably only as effectively as an s805 or the s808. Expect middling frames per seconds (22-28 probably, just a guess though) in demanding games if used with a 2k screen.
    Now when you put that gpu performance loss in perspective, not to mention the loss of marketing (mediatek is still considered an off-brand SoC maker, despite their success), and you see why Mtk just really isn’t an option for $700 flagship phones.

    Does that mean that Qualcomm has Sony, LG and the rest in a vice? Well there is one other giant to whom these android flagship makers can turn to : Intel, their new broadwells are built on 14 nm finFET, are astonishingly energy efficient, and offer one particular model this year which is just astounding; the Core M tablet SoC, combining their broadwell M processor with a homegrown Intel HD Graphics 5300 that wipes the floor with even the Exynos 7420 in benchmarks and in real world performance. And unlike 2013 year models these 2015 x86-64 chipsets pose no incompatibility issues, in fact they are specifically being targeted by Intel at Android/Windows Android/Ubuntu hybrids.

    So in closing, that’s my wish and hope right there, that Sony ditches Qualcomm in favour of the x86 giant. And maybe this’ll also give those Win10 fans something to cheer for (yes I know Win10 works on ARM, but all the legacy code (Win8 and backward) not to mention all the games are x86 only).

  • gamer324

    That’s abit misleading, the optimisation process isn’t really all that different than ehat a laptop maker would have to do with an i5 or i7. And as far adding drivers to the kernel, that’s a day at most for someone with as much manpower as Sony. Give it another week for testing and optimisation. But in no way is all this work so much that oems can’t switch SoCs, even in really late stages it only costs about 1 or 2 months.
    And right now it isn’t even all that late, consider this : Qualcomm has yet to supply even preliminary s820 parts to Sony or any other manufacturer. Right now Sony is in the planning phase of the next flagship, and I for one want them to consider alternatives to Qualcomm whose chips have been getting only marginal performance boosts, either tell Qualcomm to pull its head out and design something truly brilliant or go with another SoC maker, namely Intel or Nvidia (nvidia is unlikely because their TDP is really just too much for a phone).

  • gamer324

    That’s true but mediatek SoCs lack the gpu grunt for a flagship-grade SoC, extra cores doesn’t cut it because gpus are magnitudes better than cpus at vector (graphical) processing.

  • Franciscus Michael Panggabean

    Sure he might post many bad things about Sony’s xperia, but there’s nothing troll-like about this post. Don’t just flag someone’s post because of their username before reading it beforehand. Now you’re the one who ended up looking like a troll.

    go ahead then install HTC m8 rom on your z3, it should work right ? since it got the same processor. no it wont.

    besides, you tends too oversimplifying things,
    how about the physical size of the processor?
    thermal design?
    where to put in in a small phone ?
    will the heat output effects other component such as battery?
    will people even buy a flagship with mediatek?

    im really content with my z3, and have enough with the spec race.
    spec will always change , ever couple of months . got tired of it.

    Are you serious? The only reason an m8 rom won’t work on an xperia is because the htc kernel does not have the xperia component drivers (display, camera, radios, sensors, speakers and mics). That is all, I suggest you take a look at the cross development section of xda-developers.
    The physical size of the processor is almost irrelevant because most all mobile SoCs built on a similar die size are small enough to be configured by an OEM into their chosen form factor. The fact that you bring up thermal design is a joke in and of itself because we are literally in the comments section of an article about the failed thermal design of the z4 (overheating=failure of heat dissipation).
    People buying or refusing to buy an mtk flagship is quite irrelevant to the topic you and I were talking about (optimisation for SoCs and their pertinent impact on the design schedule of a phone), so really don’t know why you wrote that bit in there.
    And good on you for being content with what you have :-), we honestly need more of that these days.

    It’s nice to have a civilised and rational conversation. Especially here, where people get personal and quite literally want to stab eachother over a phone.

    About the m8 rom,my point was:

    Android is not the same as windows.

    You CAN install Windows 8 on 2 machine with the same i7 processor (Asus and acer laptop) without specialised driver for (example: the web cam). Windows will run but the webcam will not function properly.

    But on android, you can’t install lollipop(with identical rom package) on 2 phones with identical Qualcomm processor (example z3 and m8) without full optimization for each phones.

    Thermal design wasn’t a joke, hahaha because each phone is different. they need of a specialised design for each product . especially if you change the processor. Since each processor behaves differently. the fact is it isn’t a modular platform.

  • TGO

    I can’t believe they’re on the Z4 already, I have Z2 and I’m happy with it and don’t see much difference.
    But it’s crazy that there a Z4 already.

  • Lorenzo

    And for the z3 sound iussues?

  • Svnjay

    OMG, stop embarrassing yourself Timel. The Z3 Compact was the best selling phone in Japan in May
