Samsung is updating a number of mid-range devices with the September 2018 security patch. These devices include the Galaxy A8 (2016), Galaxy A8+ (2018), the Galaxy C7, and the new Galaxy A8 Star. Samsung has already updated its flagships with the September patch, and more of the company's devices should be getting a similar update in the coming days.
Galaxy A8 Star update also includes a Galaxy Note 9 camera feature
The September 2018 security patch doesn't involve fixes for any widespread vulnerabilities, but it does fix more than the usual number of critical vulnerabilities in Android and an even higher number of vulnerabilities in Samsung's software. The Galaxy A8 Star update is also special because it brings support for AR Emoji in the camera app and also the new Scene Optimizer feature from the Galaxy Note 9. Scene Optimizer is a funky way to say the camera will now better detect the type of scene and subject being captured. While it doesn't seem to make any difference, it would be nice to see Samsung bringing it to other flagships as well (something that may yet happen with the Android 9.0 Pie update).
To see if the September update is available for your phone, open the Settings app, tap Software update, then tap Download updates manually.
