  • Alex Bretana

    Installed this update (.546) on my Z3c (US) last week and have had really bad battery life – due to the data signal being way weaker and heating up my phone. It’s made my phone a Wi-Fi data-only phone until the next update :(

  • Snidhin Ninu

    OOOPS… Battery draining faster, and charging slower.. the reverse is required…

    Yesterday in 5.0 D6633 charged abt 75% in 2 hrs, Today in 5.1 D6633 charged about 30% in same 2 hrs…


    Here in Iran this firmware has problem with 2 of 3 carriers in USSD codes too, and generally battery sucks after kitkat and getting worse after each update sadly!
    We expect Sony widely release a fix bug update including for D6633!

  • ismail

  • Snidhin Ninu

  • Tochi Nwodu

    One important feature using short codes (ussd) and after various complaints sony decided to widen the 5.1 this is just lame
    Had to downgrade the second time
    Having used Algeria and Russia firmware

  • Fawaz

    USSD not working

  • Ayad Fahos

    Ussd not working in z3 dual after apdate 5.1 plz fix fast

  • Solomon

    After 5.1 update ussd code not working pls sony do the needful

  • Allah Bakhsh

    Yes so petty as after updating to android 5.1.1 USSD code not working here in Afghanistan.

  • Martín Balzarini

    Along with USSD codes not working, for me, in Argentina, the 5.1.1 update has caused lots of network issues. The phone takes for ever to get signal when leaving a wifi area and going toe Cell data. And if you are in an area with bad coverage and move to an LTE area, the phone doesn’t detect LTE and forces you to do an on/off or airplane mode, and sometimes a reboot too.
    Also, sometimes it will get signal, show 3G or H+ but you won’t get data, you have to manually disable/enable cell data for it to work. NOT WORTH THE UPDATE.

  • John Jay

    not only USSD does not work, so as array of bugs: There is a spike of lags, message sent is translucent and no time stamp, SMS avatar missing, battery drains faster like 2% in 5.0 and 9% in 5.1, but charging very slower almost 4 hours to full, no charging time left in lockscreen, minutes in lockscreen clock is bold. better not to upgrade I returned to 5.0

  • Tochi Nwodu

    Exactly…you are 100% correct 5.1.1 is just a big joke…I was hoping they fixed ringtone volume..still very low
    The only thing I really enjoy about it was ‘how colourful the Ui looked’
    I downgraded back almost immediately

  • Rotzz Lely

    Got it 2days ago in Kenya USSD not working. Can’t do my transactions, access to my bank paralyzed.. A high ended phone becoming an expensive venture … I hate it after the upgrade. First it was excessive over heating then followed by on-off sessions.. But now its stable.. I need that bug fixed update like yesterday…

    Other bugs are like ring tone function. Today I had 8 consecutive missed calls. It was so frustrating to mention that high ended smartphone not able to do what a 10 dollar phone can do better.

    Phone calls were hanging some don’t go through… Nkt

    Sending SMS is automatically converted to MMS… None of my mass messages went through coz of this bugs.

    Honestly speaking am grounded by this phone

  • Rotzz Lely

    How can you downgrade… I need to do this… Coz I will not want to be inconvenienced in a pilot plot

  • Solomon

    Bought Sony Xperia Z3 dual sim about 2 weeks back. Things were going fine until i upgraded it to Android 5.1.1. Since then, I have started facing lot of issues which are mentioned below:

    1. Low Sound of Multimedia:
    Sometimes when i try to play any clip or multimedia file, it doesnt play with full sound, infact the sound is tooooo low. Even if you try to push the volume to full, still it will not increase the volume of the video. So, I always have to restart my mobile.

    2. Mic issue:
    When I plug the provided handsfree, the other person cannot hear me and as per him its complete pin drop silence. Then I unplug the handsfree and try to continue saying “Hello Hello” but still no luck, however I can easily clearly hear the other person. Then I restart my device and try to talk again without handsfree, and it work.

    3. USSD String not working:
    When I try to recharge balance through ussd string, it doesnt show any mesage. Moreover, when I try to check my balance it doesnt show any message.

    4. Battery Drains:

    Battery drains too quick :'(

    5. Heat-up:

    Mobile heats-up alot that it irritates. Handsfree doesnt work for mic and if you use without handsfree then it burns your skin…mean WTH?

    My cellphone is just 2 weeks old. I bought it for 2100 SAR in Saudi Arabia and facing issues since then. I went to Sony outlet which is far away from my home and they said, ‘no such issue sir, please leave your set here we will check. You can collect after 15 days”.

    Is this why I spent 2100 sAR? Its a big amount. I would have bought any good mobile phone with this money. I switched from iPhone5s and thought its an intelligent move but feel so stupid after taking this decision. Please resolve these issues or return me my had earned money.


  • RiAz

    sony should giive everyone money . fucking sony…give my money . i buy another smartphone….

  • gnturibi

  • Chester Charles Bennington

  • MichaelGopan Jackson

    Come on Sony Its Too Late to Fix Ussd,My phone is running with the problem of USSD since the last update…….

  • Solomon

    Sony u will lose ur customers if u don’t rectify this ussd problem

  • Dmitry Morozov

    I have the same problem in Moscow /Russia. Bought it in the first day it came out with Android 4.4.4 and I was happy, no problem at all!!! After 5.0.2 update I got more function and design but less battery and stability. After 5.1.1 update I can not use my phone because I have microphone problems, more battery, sound, camera auto light correction and many other issues. I know how to downgrade my phone but why should I do it!!!??? I want proper problems solving update as soon as possible!!! I use only Sony premium products for 5 year (TV, phone, notebook, ps3, ps4 and may others), but if Sony doesn’t care about me as a customer, I am thinking to change them to Korean brand…

  • Jacinto Ferreira

    Ussd not working for all carriers in Portugal. I contact support but the answer is only one. Reset phone and contact carrier. The problem is not on the carriers but is on the phone last update. I’m very dissapointed with Sony support

  • Kenneth Evaldsson

    Question: The Generic version for Xperia Z3 Dual 5.1.1 mentioned above, does it contain the localisation for Sweden?
    I’m getting tired of waiting for Central Europe 1 not being updated from 5.0.2 :-(

    In Kenya, the D6683 variant doesnt seem to move beyond Android 5.0. Sony, work on this. This is a capable device.
