A small firmware update has been released for the T-Mobile Xperia Z1s (C6916) that moves the build number from 14.4.B.0.37 to 14.4.B.0.56. This is a minor update with no noticeable changes. The 4.2MB update is currently rolling out OTA and the good news is that if you are rooted, this is maintained after the new update is installed. If you have updated, do let us know your impressions below.
Thanks Matthew and WilliamTell13!
