Sony has started rolling out a new firmware update for a couple of its 2012 range of Xperia handsets — Xperia U and Sola — that fixes tons of bugs on these devices. The most notable change brought about by the .184 firmware update is the signal disappearing issue fix, which should please all Sola and U owners out there.
The firmware update also fixes some other major bugs like the low in-call earphone volume, poor battery life, touch screen sensitivity, random Wi-Fi disconnections, and random restarts or freezes. There is an improvment in the overall performance of the phone as well.
There are quite a lot of other bugs that the firmware does not fix though, including MTP driver issues and display flickering when auto-brightness is enabled. The full list of bugs that have been fixed and are yet to be fixed can be found here.
Sony will soon start rolling out the Ice Cream Sandwich update for the Xperia P, and the updates for the Sola and U should follow soon. Hopefully, the ICS update for these devices will not contain these bugs, and will be relatively bug free.
Looking at the amount of bugs the handsets (Sola and U) shipped with, Sony should have had done more testing with the firmware. It is completely unacceptable that a phone be shipped with such serious issues right out of the box, and owners need to wait 2-3 months for any kind of fix.
