In a sign that the official Android 6.0 Marshmallow firmware update may soon be landing on Sony Xperia devices, the update was recently certified by the Wi-Fi Alliance for a number of Japanese models.
Android 6.0 Marshmallow was Wi-Fi Certified for the Sony Xperia Z5 on NTT docomo (SO-01H), SoftBank (501SO) and au (SOV32) as well as the NTT docomo Xperia Z5 Premium (SO-03H). The latest Android version was also certified for the Xperia Z4 on NTT docomo (SO-03G), SoftBank (402SO) and au (SOV31).
It is worth pointing out that this certification by the Wi-Fi Alliance is not the same as the PTCRB, so do not assume that the new Android 6.0 firmware is a matter of two to three weeks away. Sony Mobile has so far kept quiet about official release dates for Marshmallow, but we expect some firm news shortly after the New Year.
