i got and email 1 month ago from sony that my phone has a new software to be up to dated and it said i can do it with xperia companion or wait for it to release for phone,i tried with companion and first after downloadin the update it failed with an error that my phone is not fully charged but it was fully charged and this week i tried again and this time after it turned off the phone to prepare the device,it showed the same error again and my phone was 100% charged
