The July 2019 security patch, which has already been released for the Exynos Note 8 in some markets, brings fixes for 10 critical vulnerabilities in the Android OS along with patches for over a dozen high-risk vulnerabilities. As you'd expect, some vulnerabilities that only affect Galaxy devices have been plugged as well, including one that could allow enabling and disabling Bluetooth without needing to unlock a device.
If you're using a Galaxy Note 8 on Sprint, you can try downloading the update over the air from the Settings » Software update menu on your phone by tapping the Download and install option. Updates are released in stages, so not everyone may get it right away. If that's the case for you, simply try again after a couple of hours, or just skip the queue and upgrade using the latest firmware from our firmware section.
