With just a few days left before we enter the month of June, Samsung has released the May 2018 security patch update for the Galaxy Note 8 in a number of markets, following its release for the US last week. The update is available for download over the air and is around 700 MB in size. Don't let the size fool you, though, as the update doesn't bring anything other than the latest security fixes. The build number gets a bump up to N950FXXU3CRE5.
Galaxy Note 8 May 2018 security patch
The May 2018 security patch brings fixes for six critical vulnerabilities discovered in Android, along with fixes for seven vulnerabilities that affect only Samsung devices. As usual, there are quite a few lower-risk vulnerabilities that have been patched, details of which can be found on Samsung's security bulletin. If you have a Galaxy Note 8, you can check if the update is available in your region by going into the Settings » Software update menu on the device and tapping Download updates manually. Of course, doing nothing will make the phone notify you about the update, but that can take a few days.
