The Galaxy J4 update is currently available only in India and bumps the software version to J400FODM4BSF3 when installed. The release doesn’t seem to bring any new features to the budget device from last year and includes just the security fixes detailed in Samsung’s July security bulletin. It contains Google’s patches for ten critical and over a dozen high-risk vulnerabilities in Android and fixes from Samsung for 13 vulnerabilities that are specific to its devices.
