North American carrier AT&T seems to be the first to be releasing the October 2018 security patch for the Galaxy Note 9. The Galaxy Note 9 October security update has been released by AT&T today, as confirmed by a Google+ user. This follows just three days after Samsung published details on the October 2018 security patch.
Galaxy Note 9 October security update debuts on AT&T
Samsung was quite fast with releasing the August and September security patches for its flagships (and many cheaper devices as well), but it remains to be seen if that will be the case for the October patch. The Galaxy Note 9 also received a major camera-related update recently, although it did not include a newer security patch. However, for markets where the camera update has not been released, it's possible Samsung will release it with the October patch. As for the patch itself, it brings fixes for a dozen critical Android OS vulnerabilities and 11 vulnerabilities that affect only Samsung's software.
If you have the AT&T Galaxy Note 9, you should be able to grab the update from the Settings » Software update menu on the phone. If you have the update already, do let us know about any changes or improvements you may notice by leaving a comment.
