Xperia Z2_17.1.A.2.55Sony is continuing to polish firmware for the Xperia Z2 and Xperia Z2 Tablet, as another minor Android 4.4.2 KitKat update has been certified for both devices with build number 17.1.A.2.55. This follows on from the previously certified version with build version 17.1.A.2.49. With the Xperia Z2 expected to start shipping in limited quantities later this month, it could mean this update is a day one update.

    They have more firmware updates for the ones that ain’t released yet than the older devices.

    Is is 4.4.3?

    Update before launch, guess Sony really is listening to costumer demands. I wonder what had to be updated at this time however. Was the Z2 ever released to a small beta testing group??

    Anyway, keep waiting on that launch date. Register for pre-sale?, yes I am.

    Plz fix 4.4.2 update on z1 compact, bluetooth connection is unstable and with apt x u can’t control volume on phone and it makes a beep when trying.

    they need to fix camera focus

    4.4.3 hasn’t been released by Google yet.

    So by the time we get the Z2, we’ll need to do a big update for ‘our’ device… patience, patience….


    Don’t forget the bugs of Xperia z1 with kit kat :(

    if a release on an island with 22 million people counts as a ‘beta’ test, then yes. I’ve had my Z2 in Taiwan for a week now ;-)

    They need to fix the swipe to unlock effect. it gets ugly when you change the home screen wallpaper.

    Edit: sorry, this is for Z ultra kitkat version. i’m not sure about the others and i hope it’s not the same with Z2

    Very interesting thing I just come across at – I could choose any number of jewellery items (from the list) at very heavy discount rates (up to 75% off online) – more we buy more discount – I never seen this before.
