The Sony Xperia V, aka the LT25i, has finally received an operating system update which takes the version number to Android 4.1.2 Jelly Bean. So what does the latest Android 4.1.2 Jelly Bean update bring to this handset? Well, your firmware version will be upgraded to version 9.1.A.0.490, which (Just so you are ware) is slightly different from firmware number 9.1.A.0.489 which began to arrive on the Sony Xperia T last week.
It looks like the Android 4.1.2 Jelly Bean update affects several European countries that include Denmark, Sweden, Germany and Switzerland. So if you live in one of those countries and your Xperia V seems dead, just hang in there.
Hopefully, it will fix death bug issue and all will be well. That would be awesome.
