June security update coming to Samsung Galaxy S7 and S7 edge

As usual, the changelog doesn't specify which vulnerabilities were exactly addressed for security reasons. In addition to the June security patch, the update also includes stability and performance optimizations and bug fixes. 

When you get a notification for the software upgrade on your handset, make sure that your phone is sufficiently charged and connected to a Wi-Fi network before proceeding. If you haven't received one already, you can check for the update manually by heading to Settings > About Device > Software Updates.
