No surprise update for the Xperia M4 Aqua Sony. While the Xperia C4 was entitled to Lollipop Version 5.1 before proceeding with Marshmallow, the Nippon midrange Android 5.0 will have to wait pending its passage 6.0. No date for the key, unfortunately.
This is no longer a small hidden information in a Sony website’s support page. The Xperia M4 Aqua, who has not benefited from major update since its launch in May 2015, Android 5.0 Lollipop, happen indeed Android 5.1. Sony confirms today its customers on social networks, and shows their direct update to Android 6.0 smartphone Marshmallow. A choice altogether logical, Sony is now too far behind its competitors in order to settle for a upgrade to 5.1 when Marshmallow prepares to integrate most smartphones presented at MWC 2016.
Regarding your question @KarCerKK the Xperia M4 Aqua will skip Android 5.1 and Android 6.0 Will receive (Marshmallow).

Sony Communication however worth noting since the Nippon seems to have difficulty in meeting its commitments. His schedule indicated Indeed, there a few months ago, the Xperia C4 as it would change from Android 5.0 to 6.0, but finally received Lollipop in its version 5.1 a few weeks ago.
All terminals upgraded to Marshmallow
Recall finally that if we stick to Sony information published late last year, the Xperia Z3 +, Xperia C5 Ultra, the Xperia Z4 Tablet and Xperia M5, whose deliveries will begin by little in France, also pass them to Android 5.0 (.1) to Marshmallow. As for when this deployment, we hope it will be specified in the MWC, by the end of February.
