A small firmware update has been certified by the PTCRB for the Xperia Z Ultra (C6802, C6833 and C6806). The new build number 14.1.B.1.532 is a minor revision over the previous update (14.1.B.1.526), which recently started rolling out.
Interestingly, it is the first firmware to be certified for the C6843 model of the Xperia Z Ultra. This may suggest a release soon, although we are unsure exactly which region this SKU will be targeted to. If anyone has any details on this particular model, please let us know in the comments below.
Thanks Ben and Silas!
