We were already expecting the Sony Xperia M4 Aqua Marshmallow update to be available soon and now we learn that the rollout is just a couple of weeks away.
Canadian carrier Rogers has updated its OS upgrade schedule to reflect that the Xperia M4 Aqua will start getting the Android 6.0.1 Marshmallow update on August 3.
A quick look at the 'Details' section reveals that the update will also include monthly security patches as well as some bug fixes. Roll-out in other regions should also begin sooner than later.#
