Mystery bug epidemic causes random death of Sony Xperia Z devices, fix is incoming

by: AdrianMarch 21, 2013


After Samsung’s Galaxy S3 crushed all the Android competition during 2012 on its way to becoming the world’s best-selling smartphone, this year’s debut seemed to line up a much tighter three-way battle for supremacy.

There’s currently very little to set the Sony Xperia Z, HTC One and Galaxy S4 apart (at least in theory), which is why it’s only natural to expect the war to come down to the wire. Only HTC might be out of contention already after delays caused by component shortages.

Meanwhile, Sony seems to have a really big hassle on its hands as well, with (way too) many Xperia Z users reporting their phones are suddenly and out of nowhere dropping dead.

All over the XDA and Sony Mobile Talk forums, people are spilling their guts about sudden death episodes and the biggest problem of them all is they don’t seem to be caused by only one glitch. Several of these might have something to do with Z’s battery, but the vast majority really does come out of nowhere.


There are even folks reporting their Zs have breathed their last after only a few hours of use, which is pretty scary. In some cases, you can apparently resuscitate your breathless precious with a hard reset (power button + volume up), but most of the times there’s nothing you can do besides say a prayer, put the phone in his coffin box and return it for a refund or replacement.

On the bright side, Sony has already announced “the problem has been identified” and that a fix is currently being worked on. The “next software update” should include this fix, but there’s no ETA just yet, so it might take a while.

And although the Xperia Z is not the world’s first smartphone to encounter such issues (even the Galaxy S3 suffered from a similar epidemic), Sony is definitely going to lose any edge it might have had over Samsung or HTC. And just when we thought they could become a force to be reckoned with

    Could it have something to do with Android? Not trolling, just wondering if Google has something in the code that when phone makers do something to the phone, it accidentally causes these sudden deaths. Well Nokia Lumia 920 and iPhones have had those same problems, but still…

      That goes against the open-nature of Android itself.

      Every manufacturer has this problem to some degree. So far, it may not be worth their time (money) to investigate why it is happening & is cheaper to just replace the faulty handsets.

        I didn’t mean that Google would have done it on purpose, but yea you’re right

      Generally speaking, Android is poorly coded. The processor firmware and the OS are probably not compatible. Nokia Lumia 920 is the most seamlessly engineered smartphone to date.

        I thought Gooooooogle said that with JB they fixed many problems with the old code?

  • Imran Bukhari

    give it to xda and they’ll fix it

  • Wendhy Rigo

    Don’t worry too much about it. Sony unexpectedly swift in handling this problem they already pre-releasing the update very soon. check

    Is this also affecting the ZL?

  • John Koetsier poyo

    Believe what you see, not what you hear, says Qualcomm..
    Qualcomm explain it..don’t too says and too talk cock

  • Been using my Z for the past 4 days and I have not met one single sleep of death yet, thank God. Saw a thread on XDA discussing this. Seems like that this problem occurs to a small minority.

  • umm im plannin on buyin xperia z….but this sod problem is freakin me out…. shud i or shud i not ???

  • Wally

    I’m assuming the stores will apply the fix/update before selling the handsets? And some poor technicians are going to be applying fixes till they’re blue in the face before shipping completed units.. Especially at the rate the Z seems to be selling.

    well my lady has the xperia z and i told her to press and hold the power button down and the voume down button and it reset her phone. might wanna try that. this isnt a definite fix.
