Sony Xperia Z, ZR Android 4.4 update problems emerge


It is always nice when owning a mobile device to be treated to a later version of the operating system, but sometimes things don’t run so smoothly after installing the new software. Now we have news that some Sony Xperia Z and Xperia ZR Android 4.4 update problems emerge.

Sony has been busy releasing a number of new firmware updates that have also included the Xperia Z, and more recently the Sony Xperia ZR. Trouble is though we have been contacted by some readers complaining of issues since installing the update.

The main issue for both devices has been severe battery drain but there has also been reports of sudden reboots and overheating of the device. At the time of writing Sony hasn’t acknowledged any problems but if reports grow we may see the new firmware pulled until a fix is found.

Update: Sony has now acknowledged the problems and more details can be found here.

Have you had any problems since installing the new operating system?

    Yep. Phone stays in wake mode and the battery hardly lasts the morning.
    I was quite happy with the previous version, can anyone tell me how to reinstall that?

  2. not pleased says:

    Updated to 4.4 2 days ago. Sony Experia Z now barely lasting till lunchtime from a full charge overnight. At least on 4.3 it will last till early evening!

    After the latest update my Experia Z battery life is TERRIBLE. the battery lasts barely half a day and I now have to carry a charger with me everywhere. I have had no problems before now, have loved the phone but just a few days with the new update I find myself wanting to smash the thing to pieces with frustration.

    I’m so frustrated by this latest update. I’m having to charge my phone twice a day, it is just draining so quickly even with limited use. My phone is also getting very warm too. My phone is just totally unreliable. Please Sony sort this problem ASAP or I have to change phones.

    Same issue, my phone has gone from lasting almost two days to having to take a charger to work with me! I’m not even allowed to use my mobile in work!!! So it’s draining battery just on standby!

  7. HelenaK says:

    Lots of problems – battery is dying halfways through the day (just checked my work emails one day), and yesterday I didn’t touch the phone, it died on my way home on the tube (before I even got to the train station). It’s also very hot. Agree with other comments here!

    My battery is draining rapidly since Sony’s software update, my Xperia has become a landline as I have to keep it connected to the mains. I have turned off auto synch and location services but the problem persists. Thinking of taking the sim card out and putting it back in my old Nexus phone. Help please!!!

    The new version of Sony OS is a total FAIL. My device is overheating like crazy, battery life of less than 4 hrs, random reboots. I’ve reinstalled the OS multiple times adn done factory resets to no avail. Sony needs to get its act together. Or they need to replace my device when it’s battery burns out.

  10. Rainey says:

    Ever since the update my device has had crazy-fast battery drain and heats up to the point that I’m afraid it might burn me. I have to charge it up constantly now.

  11. Asheel Soorjbully says:

    I am having the same draining problem with my Sony Z, I did however notice that if I switched off my location and then reboot the phone, the battery life does increase however I do not want to switch off my location nor do I want to reboot my phone continuously, this is a terrible update from Sony.

  12. Father Gabriel OP says:

    I am having great battery drain and high overheating eversince I updated a few days ago my Xperia ZL to OS 4.4.2 – It does not look good at all. I am afraid of the great overheating especially. I hope that Sony will tackle those two issues ASAP.

    New firmware has lots of problems. First and main one is lag problem. On 4.3 firmware working insane smoothless but 4.4 it is working like hell. Second one sony’s softwares are still old version. On 4.3 using albüm walkman videos 6.xx version in 4.4 4.xx version. Third one insane battery drain. Positives are opening scene and themes.

  14. Debbie Burbridge says:

    I can no longer use some password protected apps. I have AVG installed on my phone and have passwords on half a dozen of my apps and after the update I can no longer use the password. If I touch the screen to enter the password it doesn’t bring up the keyboard for me to enter it. Have tried taking the password off and resetting it and uninstalling app and reinstalling it but nothing works. Extremely frustrated!!!

    Power-off Button doesn’t work anymore (but I don’t think it’s actually button since Power-off is working) on my Sony ZR after upgrading to 4.4.2. This means that if my Phone goes into standby I can’t wake it up with the powerbutton, but I have to insert the chargingcable which activate the display.
    For me this Phone is now USELESS!

    I have a Sony Xperia from T-Mobile. After my phone updated (which I tried hard to keep it from doing) the power button does not work as well, my game apps lose the connection, and my internet does not work. When I try to use the internet I get either a white or black screen. I restarted it and it worked temporarily. After restarting it a second time I was in the middle of using the internet and the screen went black after about three minutes. Seriously not impressed.
