Posted on Dec 20 2013 - 6:53pm by Anurag Kumar

Sony finally rolled out much awaited android 4.3 14.2.A.0.290 firmware update on both Xperia Z1 and Z Ultra, though it’s a nice update with some cool “Xperia Themes”, smooth UI and improved camera functionality still users are facing many bugs on it. Xperia Z1 and Z Ultra users are reporting to us many bugs which we will discuss in this post later. First let me answer your question, is the next update for Xperia Z1 and Z Ultra due soon ? Yes it is.

Just now we found that android 4.3 14.2.A.1.XXX firmware update will soon hit Xperia Z1 and Z Ultra as a big fixing update over previous  android 4.3 14.2.A.0.290 firmware update. At present 14.2.A.1.XXX firmware is in testing, most likely to come very soon but we can’t 100% confirm that the same build will be rolled out, it may happen that a higher build to 14.2.A.1.XXX firmware will be rolled out ( if something changes during testing ).

If you still have not updated to latest android 4.3 firmware for Xperia Z1 and Z Ultra, kindly do it from below link.

Let’s talk about bugs faced by many users in Xperia Z1 and Z Ultra android 4.3 14.2.A.0.290 firmware update.

  • Many users are getting this error when you navigate to “Sound enhancements -> Settings”, it shows “Unfortunately, Sound enhancements has stopped.”
  • Battery backup on standby mode has decreased a lot now.
  • RAM consumption has increased after this update.
  • For some importing contacts have become an issue.
  • Yellow hue issue still present, though UI of new themes are more white but on stock themes it is still yellowish.
  • Noise in camera pics have reduced but it is still present.
  • Touchscreen issues, screen is not responding well on Xperia Z1, it seems a hardware issue though who knows a software update may fix it :P

Factory resetting has fixed some bugs not all.

Another thing it was mentioned Sony Support official staff member that an update is due in Jan 2014 for Xperia Z1 where we will see the “White Balance app” settings finally.

    On 4.3, the sound quality of walkman and speaker has decreased a lot. I think it’s really bug.

    4.3 is a big disappointment, battery life has reduced dramatically, handset cooks and over heats, camera doesn’t function correctly because of over heating issue and have to wait for it to cool down! Picture quality is still a mess.sound quality is poor in Walkman.
    My Z1 had been working perfect for months until I installed 4.3….they should of skipped this update and gone straight onto kitkat.

    Since the update I’ve experienced on my Xperia Z1
    -My album malfunctioning. Most of my pictures are just a black screen.
    -Walkman constantly crashes.
    -Unable to play movies.
    -Facebook is sometimes unresponsive
    -Overheats way too much way too quickly and
    -For a 20mp camera, there is so much noise in my photos it comes out looking almost vga.
