    At last, an update for the Z3+!

  • Uzair Syed

    Got my first smartphone, Xperia Z3v because I couldn’t wait for a Verizon variant for newer phone from SONY any longer. Learning the ropes of smartphones and Android now and wth stuck at Kit Kat?

  • Eduardo Otero

    You’re so lucky for being stuck with KitKat. Lollipop brings lots of problems to Z3.

    Update OK. no noticeable difference with previous version. Hope this prepares 6.0 upgrade (version is still 5.0.2 on my Z3+ dual).

  • Lee McRobbie

    Just got this and it seems to be only a stagefright patch. And woo an update for the forgotten z3+. Hopefully we get 6.0 or maybe even 6.0.1 by end of January or February with a SD810 friendly android.

    OK…. I have 5.1.1 on my Z2 from like 5 months or so and Z3+ is still running 5.0.2? So much visual improvements were brought with 5.1.1. It’s ridiculous that an older device has newer software for so long.

  • Alvin

    Yes, so much visual improvements, yet ruined my battery and stuttered my lockscreen

  • matiiijas

    Well, I don’t have any of these problems with 5.1.1. Maybe you should try to reinstall the software with PC Companion. If nothing official helps I recommend you to flash your phone with full wipe via flashtool (I use Customized DE ROM).

  • jag

    It got me sulking too. :(

    Good thing the previous update made it atleast bug free. Do you think we need to do a clean install for this new update?

  • stuck_788

    just received the update… but my question is: what is all about? stagefright security or what?

    only xperia serie Z receive update after update i have xperia c4 i am disapointed

  • Alvin

    Yeah on .576 i didn’t experience this battery problem, but after updating it to .200 and .232, the battery performance is greatly reduced, not just sot, but also the standby time…

  • matiiijas

    I see. I didn’t update either to .200 or .232, because they had worse stagefright security issues. Now I’m on .264 with full stagefright fix and no problems with the battery or anything. Try to update to .264.

  • Tenglong

    two issues:1. the screen keeps showing “unfortunately, the process has stopped” & “Unfortunately, Google Play Services has stopped. 2. software update screen is still showing installing. I have tried to restart the phone but didn’t work. I need help!!

  • Alvin

    i haven’t get it yet… but thanks for your suggestions, mate:)

  • rats
