Versions of the Xperia Z4 and Xperia Z5 sold in Japan have been spotted in the Wi-Fi certification database, suggesting the update is on track for the rumored release date from January.

In order for a device to be called Wi-Fi compatible, it must be certified by the WiFi Alliance, the body that develops the wireless communication standard. Existing devices running new Android versions must go through the same process, and that can provide a glimpse at OEM’s plans for Android updates.
