Samsung is readying Android Marshmallow updates for the Galaxy A7 and the new Galaxy A5 (2016). Both firmware upgrades include the latest Android OS version, complete with Doze mode, enhanced app permissions and improved notifications.
The latest security patches are all included in the new (June) builds, too.
Russia is getting Marshmallow for both devices right now, while the Galaxy A5 (2016)'s Marshmallow is also available in Serbia and Turkey.
The updates are seeding to even more countries as you are reading this, so we expect a massive rollout in the next couple of days.
Thank you, Sarper Eroglu and Shuhail, for the tips!
