A new firmware update is reportedly arriving on Sony Xperia TX (LT29i) units out there, with version 7.0.A.3.197 attached to it.
The update has been spotted only on Vietnamese units for the time being, and without a changelog to detail what novelties it brings along.
As XperiaBlog notes, it remains to be seen what changes Sony has in store for users with the new update when compared to firmware version 7.0.A.3.195 that the Xperia T (LT30p) runs under at the moment.
Most probably, this update was pushed out only with a series of bug fixes packed inside, along with some minor enhancements, this being the main reason for which Sony did consider it necessary to offer release notes for it.
Unfortunately, there is no info on whether the update will be released for units in other markets around the world as well, but stay tuned for more on this.
