After releasing Android Marshmallow to the top-end Xperia Z series phones, Sony is reportedly getting ready to roll out the software update to the mid-range Xperia M4 Aqua.
A new firmware (build number: 26.3.A.0.131), understood to be Android 6.0 Marshmallow and bound for Xperia M4 Aqua, has passed certifications from the PTCRB, reported Xperia Blog.
PTCRB is a cellular operators' forum, which authorises certification program for devices operating telecommunication bands in North America. After getting the nod from any of these governing agencies, it takes a week or two for companies (in this case, Sony) to release the OS update en masse to the public.
Sony Xperia M4 Aqua was supposed to get Android 5.1 Lollipop along with Xperia C4, C5 Ultra, Xperia M5 and M5 Dual in the first quarter of the 2016, but the company via Twitter informed fans that it will skip the incremental Lollipop update and instead release the v6.0 Marshmallow directly to M4 Aqua later in the year.

With PTCRB certification in hand, Sony is likely to release the update by the end of July or early August.
The Marshmallow will bring the Doze power-saving feature, an improved "Now on Tap" search option, silent mode added to the sound profile, more shortcuts, an intuitive boot security system, performance enhancing tweaks and Google's latest security patch.
