The Samsung Galaxy A8 is all set to get Android Marshmallow update soon. The dual-SIM (Sm-A800F) variant of the Galaxy A8 has just received WiFi Certification for Android 6.0 build.
Samsung launched the Galaxy A8 running Android 5.1 Lollipop last year and its good to see Samsung updating its entire 2015 line-up to Marshmallow.
At present there is no word on when the rollout will begin but the WiFi certification is a clear sign that the final build is ready for prime time. Just hold out your horses a little longer and keep checking for software updates.
