Samsung published its November 2026 security bulletin on November 3: 155 fixes from Google and 24 from Samsung, including 20 critical fixes — more than three times October’s Google count. Why Galaxy owners should install it the day it arrives, and the five steps to do it.

Your Galaxy buzzes with a software update right as you’re heading out the door, and you tap ‘Later’ without a second thought. Short answer: install this one the same day it shows up. Samsung published its November 2026 security bulletin on November 3, ahead of the update reaching Galaxy phones and tablets, and it is a much bigger patch than usual.

Why it matters: SamMobile counts 155 fixes from Google for Android plus 24 fixes from Samsung itself, and all 20 fixes rated critical came from Google. Samsung’s bulletin describes 17 flaws in Galaxy software and notes that some items cannot be disclosed at this time. The flaws it does describe include a bootloader flaw rated high, a certificate check that allowed a SIM lock bypass, and weaknesses in Contacts, Dialer and Messages.
