As we read the other day in XperiaBlog some users were reporting the sudden death of their Sony Xperia Z, the phone worked perfectly, but from one moment to another it turned off and it was impossible to turn it on, by means of a restart some users have been able to revive it, but for a short time.
Well, Sony has been quick and has found the problem and has solved it in the form of update. Something that should not have happened since we are talking about its flagship, which is not cheap at all.
Si tu Sony Xperia Z has not received this update, you can go through the tutorial we have on how to flash the Sony Xperia Z and install it by yourselves and save yourselves from sudden death. If you are not in a hurry, the update will arrive in the next few days by OTA or by PC Companion.
We already saw something similar in the Samsung Galaxy S3 where from one day to the next the sudden death of these smartphones occurred. Although Samsung took a little longer to fix the problem than Sony. In these cases we are faced with the eternal debate of why some smartphones that are high-end and represent more than any other to the brand come out with this series of problems. In a hurry to get it on sale? A bad set-up?
