The HSPA+ version of the Sony Xperia Z Ultra (C6802) has just been released across a number of regions in Asia and Sony has already pushed the handsets very first firmware update. It appears to be a relatively minor update moving the build number from 14.1.B.0.461 to 14.1.B.0.471.
The Android 4.2.2 update keeps the phone on the 3.4 kernel. The update appears to bring better stylus support sensitivity and performance enhancements. If you’ve noticed other changes, let us know in the comments below.
Thanks Anurag and Ben!
