Sony UK apparently acknowledged that Xperia handsets will start receiving Android 6.0 Marshmallow update from March 7 onwards. The first set of devices that are likely to receive this firmware includes Xperia Z3+, Sony Xperia Z5 line up and Xperia Z4 tablet. Not to forget, PTCRB (certification authority) has apparently certified the new firmware for Z3+. The new build number is reported to be 32.1.A.0.434, Mobi Picker reported.

History Of Beta Testing And Certification

According to Android Authority, sometime in December 2015, the Z4, Z5 and Z5 Premium running the Marshmallow firmware made a visit to the Wi-Fi certification database, which pointed out the imminent arrival. And towards the beginning of February 2016, Sony launched a beta program specific to Z3, Z3 Compact, Z2 in Italy, Spain and Netherlands. With testing almost done and dusted, it’s time for Sony devices to start receiving the update across the globe.

It is worth noting that Xperia Z4 Tablet, Xperia C4, Xperia C5 Ultra, Xperia M4 Aqua, Sony Xperia Z3+ and Xperia M5 will reportedly be updated to Android 6.0 Marshmallow directly by skipping Android 5.1.1.

The Android 6.0 Marshmallow update is expected to roll out to the following Sony devices at some point this year: Xperia Z3, Xperia Z3+, Xperia M5, Xperia Z4 Tablet, Xperia Z3 Tablet Compact, Xperia Z3 Compact, Xperia Z2, Xperia Z2 Tablet, Xperia M4 Aqua, Xperia C4, Xperia C5 Ultra, Xperia Z5, Xperia Z5 Compact and Xperia Z5 Premium.

However, Sony will not update the Xperia Z1 and Xperia Z1 Compact released in 2013 and also the original Xperia Z series with the latest firmware, Android Authority reported.
