Along with these, security patches, you also receive some bug fixes and stability enhancements. Moreover, if you were waiting for the Android 0reo Update then if you’re on a Galaxy A3 2016 then just forget about it, it’s sadly not going to happen.
However, the Galaxy A7 2017 has a slightly higher chance of getting it compared to the A7 2016 variant. Samsung is currently running the Oreo beta program for its Galaxy S8/S8 plus in the US, EU, and its home country and soon it will expand to other countries as well.
Apart from that, the final build will come in 2018 as per confirmed by Samsung Turkey a few weeks ago, then we should start expecting Samsung to get Android Oreo 8.0 for its mid-range devices and that will happen somewhere in May or July of 2018. So, its a long journey for the Galaxy A7 2017 to get Android Oreo.
Meanwhile, Google has already pushed the developer preview of Android Oreo 8.1 for its Pixel and Nexus devices, so Oreo 8.0 isn’t the latest version of Android anymore.
