The recently announced Galaxy A6 and A6+ now have a clear update roadmap, which was made official via the Samsung security blog.
As some of you may already know, the Korean giant has different update policies for its devices - obviously, the more expensive smartphones get more frequent updates - every month. This means the Galaxy S, Note and some of the A series smartphones.
As for the Galaxy A6 (2018) and A6+ (2018) - they will follow the last year's A3 (2017) and A7 (2017) by receiving the latest Android security patches every three months. On top of that, the Galaxy A6 and A6+ should receive two major OS updates since they run Oreo 8.0 out of the box. So expect Android P and Android Q to hit the handsets eventually.
My phone does not have an optiont for updating my phone.
Not everyone has money
It's not a budget thing, A10 is bottom of the line, 1/3 price of A6+, and came out cheaper than J7. Yet it gets Android Q in April. It must be to do with the age.
