A new Android 4.4.4 KitKat firmware build has been certified for both the Xperia Z1 Compact (D5503) and Xperia Z Ultra (C6833). The certification moves the firmware build from 14.4.A.0.108 to 14.4.A.0.118, so we’re probably looking at a small update with bug fixes and performance enhancements. The Xperia Z1 has not seen an update so far, but expect it to follow very soon.
There’s still no sign of Android 4.4.4 hitting the Xperia Z2 yet, which seems a bit odd given that Sony has left its flagship languishing on an older Android build compared to the older Xperia devices. We’ll let you know as soon as that changes.
