Sony Xperia M4 Aqua to jump from Lollipop to Marshmallow

Sony released the Android 5.1 Lollipop for the Xperia M5 Single and Dual variants earlier this week. That prompted Xperia M4 Aqua owners to ask when they would be receiving the same firmware update, if not Marshmallow. We've got bad news and good news for you: there won't be any Android 5.1 but the M4 Aqua will immediately jump to Android 6.0. Yay!

That's something we've been expecting too since Sony announced that Marshmallow would be coming to the latest Sony Xperia devices--the M4 Aqua included. Sony Mobile will be rolling out the firmware updates slowly in different regions. We have to wait for Marshmallow a bit though but small updates were released for Android 5.0, at least, in the Nordic region. The Xperia M4 Aqua models E2303 and E2333 (Dual) can now be upgraded to build numbers 26.1.A.3.92 and 26.1.B.3.91, respectively.

Download the Android 5.0 Lollipop FTF firmware files for the Xperia M4 Aqua:

Sony Xperia M4 Aqua (E2303) 26.1.A.3.92 Nordic Generic
Sony Xperia M4 Aqua Dual (E2333) 26.1.B.3.91 Nordic Generic

We have no idea what's included in the small Android 5.0 update but we're assuming some bug fixes. Meanwhile, expect Android 6.0 Marshmallow to bring the Sony Xperia M4 Aqua new app permissions, Doze Mode, Google Now On Tap, Silent feature, Do Not Disturb mode, and longer battery life. The OTA notification should appear on M4 Aqua phones very soon.

      You got it of amazon?
      Mine hasn’t gotten any updates.
      Other models got .167 update, but mine hasn’t.
      Pretty sure it won’t be updated, until 6.0

        Yeah! from Amazon. I read rumors that we would get M before year end. But it’s already Feb and this article was the only mention I’ve seen.

    i installed marshmallow on my E2303, but, it shows poor wifi signals (on places where i had 90% signal strength before update) everything else is ok. best feature is improved security

    let me get this straight, i have the sony xperia m4 aqua e2303 with lollipop (5.0) and if i download this
    “• Sony Xperia M4 Aqua (E2303) 26.1.A.3.92 Nordic Generic”
    my phone will be upgraded to marshmallow?
    or do i need to wait for the update, because it has now been about a month that whenever i turn on my phone it says “android is upgrading” and i feel nothing happens. if i turn my phone on and off 15 times for fun it still says “android is upgrading”.
