Mobile arm of Sony is reportedly gearing up for the release of Android Marshmallow to two of its 2015 flagship Xperia series models.
Soon after the Google began rolling out Android Marshmallow in October, Sony announced the list of its Xperia devices eligible for the update.
The company in its bid to encourage fans to contribute for the development of the new update invited people to test Marshmallow concept code. Close to three months have passed by with no news of when the Sony will actually commence the roll-out process up untill now.
A report has surfaced online that Wi-Fi Alliance has certified the Android Marshmallow firmware bound for Sony Xperia Z5 and Xperia Z4 in Japan.
Wi-Fi Alliance certification has been granted to Sony's 2015 flagship Xperia Z5 Premium (SO-03H) of NTT Docomo, Xperia Z5 of NTT docomo (SO-01H), SoftBank (501SO) and au (SOV32).
Even the Xperia Z5 predecessor Z4 models have received the nod from Wi-Fi Alliance. The list includes Xperia Z4 of NTT docomo (SO-03G), SoftBank (402SO) and au (SOV31), reported Xperia Blog
Though the certification is granted to devices specific to Japan, the Android Marshmallow roll-out for international variants are likely to commence a few weeks later as it is a common practice among Google affiliated OEM (Original Equipment Manufacturers) to release update in phases.
In 2014, Sony had promised to deliver Lollipop update to flagship in January 2015, but due to emergence of bugs, the roll-out process got deferred to March.
This time, we believe Sony might surprise fans by releasing the update by this month-end.
