Xperia Z2 with Android4.4.4

Xperia Z2(D6503)にAndroid4.4.4のファームウェアが配信され始めたので、FTFファイルを作成・使用して、手動でアップデートしてみました。



Sony Mobile が昨日11月4日より、Xperia Z2 と Xperia Z2 Tablet に対して Android4.4.4へのアップデート(ビルド番号:23.0.1.A.0.167)を配信し始めたことが発表されています。

  • Since its first unveiling at IFA, the reception around PS4™ Remote Play** on Xperia Z3 series has been fevered, far exceeding our expectations. Our initial intention was to wait until early in the New Year to extend the experience for Xperia Z2 and Xperia Z2 Tablet users, but both demand and excitement meant we just couldn’t wait. With the PS4™ Remote Play launch for Xperia Z3 series here, Xperia Z2 and Xperia Z2 Tablet will now also be “PS4™ Remote Play ready” with full DUALSHOCK®4 Wireless Controller compatibility… ready to act as a remote screen to connect and control your games on PlayStation® 4. PS4™ Remote Play is also available for PlayStation® Vita and PlayStation® TV, which is rolling out in Europe starting November 14, but Xperia is – and will remain – the only smartphone and tablet range where you’ll find the full and official PS4™ Remote Play experience.
  • Music sounds better both a) turned up and b) in Hi-Res. It just does. Xperia Z2 and Xperia Z2 Tablet will now support built in (via 3.5mm audio jack) Hi-Res Audio playback from both PCM and DSD files, in addition to the USB Hi-Res playback. The WALKMAN app also adds Sony’s DSEE HX technology, enhancing the sound of your MP3, AAC or Music Unlimited tunes, restoring the experience sometimes lost in compression by these formats. And, because different headphones sound slightly different acoustically, Xperia Z2 and Xperia Z2 Tablet now give you the option to specifically select optimized settings for different Sony headsets.
  • We’ve invested heavily in building our Smart Social Camera portfolio over the past year, in terms of creating the richest ecosystem with a range of useful / professional / fun experiences both from in-house and our creative partners – this update means Xperia Z2 and Xperia Z2 Tablet users can enjoy our latest and greatest Xperia Camera apps; Sound Photo, AR fun, Multi camera and Face in.
  • Xperia stands for the most premium, fun and entertaining mobile experiences – experiences which, of course, create demand for more juice. This update includes the latest version of our acclaimed and popular Battery STAMINA Mode; and brings Ultra STAMINA Mode (to Xperia Z2, limiting a number of phone functions), giving you even more prolonged usage – based on a full charge, we estimate Xperia Z2 to last more than a week in standby when in Ultra STAMINA Mode.
  • This update also brings some of our best proprietary smart features. Quick settings that allow you to personalise faster than ever – Smart screen rotation automatically determines when the screen should be rotated according to the way you hold the device. So, it prevents unwanted rotation, such as when you lie down on the sofa to browse the web… and “Record Screen” lets you record a video of what you’re doing on-screen. You start it in the same way you’d normally grab a screenshot – give the power button a long press, select “Record Screen” and the phone will start recording whatever you might be doing. Perfect for showing off a certain feature, capturing a top score, or even PS4™ Remote Play gameplay..?!
  • Xperia Z2 and Xperia Z2 Tablet are compatible with all our SmartWear apparel and Lifelog, but they will now unlock when SmartBand, SmartBand Talk or SmartWatch 3 is in close proximity thanks to Bluetooth Unlock. And, not only that, this will also work with all and any of our Bluetooth accessories and headsets… simply set up in “Settings – Security”, then press the power key, and all will be unlocked when the accessory is nearby… useful!

個人的には Smart Lock(Bluetooth機器による端末のアンロック)とスクリーンレコード機能(動画キャプチャー機能)の追加が非常に嬉しいところです。これで Xperia Z3 の購入見送りはほぼ確定ですね。

ということで、既に配信が開始されているのなら手動アップデートも出来るのでは?と思ったので XperiaFirm で探してみたところ、ありましたー。

Xperia でファームウェアの手動アップデートを行なう際の流れは次のようになります。

  • XperiaFirm で最新版のファームウェアデータをダウンロードする
  • FlashTool でダウンロードしたデータからFTFファイルを作成する
  • FlashTool で端末にFTFファイルを焼く

設定 > 端末情報 と進むと、OSのバージョンとビルド番号が共に最新のもの(OS:Android4.4.4 / ビルド番号:23.0.1.A.0.167)に変わっていますね。やっほーい。

Xperia Z2 の端末情報を確認


ファームウェアのアップデートが来た時に手動ですぐに適用できるのが、SIMフリー版の Xperia の素晴らしいところです!

早速気になっていた Smart Lock と スクリーンレコード機能を使ってみましたが、これは色々と捗りそうなステキ機能っぽいです。この辺りについてはまた改めて記事にします。
