Samsung Galaxy A8 (2015) getting Android 6.0.1 Marshmallow update, only dual-SIM model
It's understandable that Samsung wants customers who purchased its flagship smartphones to be up to date with the latest Android releases coming from from Google, but there are more consumers who own mid-range handsets which are usually getting updates very late.
But, as the saying goes, it's better late than never. So, one of the mid-range smartphones launched by Samsung last year, the Galaxy A8 is now eligible for an Android 6.0.1 Marshmallow upgrade. Since the phone made it to market in August 2015 with Android 5.1 Lollipop onboard, it took Samsung more than a year to bring it to Marshmallow, which isn't the last version of the OS released by Google.
If you own the Galaxy A8 (2015), then you should know that the update is only available for the dual-SIM version. Dubbed Samsung Galaxy A8 Duos, the smartphone was released in India last year, at the same time as the single-SIM model and running a similar version of the OS.
Aside from the usual new features and improvements included in Android 6.0.1 Marshmallow, the update also contains the September security patch, which has already been pushed by Samsung to several high-end Galaxy smartphones.
It's also worth mentioning that the update is about 890MB in size, so make sure your phone is connected to a stable Wi-Fi network to avoid mobile data charges. Keep in mind that the OTA is pushed in stages, so it might take a few days to show up on all Galaxy A8 Duos devices.
