Samsung’s November 2025 update brings 45 security fixes and changes the phone update list

Samsung has just shared all the details about its new software for November 2025, including a large security update and a fresh list of which phones and tablets will keep getting support.

The good news is that the November 2025 One UI update is a big one for security. It brings 45 important safety improvements to Galaxy devices. Think of it as a complete safety boost for your phone.

These fixes come from three main places: many are standard Android patches, some are for Samsung’s Exynos chips, and the rest are specific fixes for Samsung’s own One UI software. The goal is to make sure your Galaxy device is safe and trustworthy. You’ll soon see this update rolling out to eligible phones and tablets.

At the same time, Samsung has updated its software roadmap, which tells users how often their devices will get new software. The company has made some important changes, adding new models and removing some older ones from the regular update schedule.

Samsung organizes its device support into three main groups:

• Monthly Security Updates: This is for the most recent and highest-end devices, like the latest Galaxy S and Z series phones, as well as a few key Galaxy A and Enterprise models. These phones get the fastest and most frequent updates.
• Quarterly Security Updates: Most mid-range phones, budget devices, and many Galaxy tablets fall into this group, receiving updates every three months.
• Biannual Security Updates: This is where older devices are moved as they reach the end of their regular support. They only get updates twice a year. Devices like the Galaxy A03, Galaxy A03 core, and Galaxy Tab A8 have been moved to this list. This is often the last step before a device stops getting updates completely.

If your device is no longer on any of these lists, it means Samsung has officially ended its regular support. While your phone or tablet will still work just as it did before, it will not get the new security patches that keep it safe from the latest threats.

Because of this, security experts suggest that if your device is no longer receiving these important safety fixes, it might be time to consider upgrading to a newer Galaxy model to keep your data secure.
