Samsung started to roll out the January 2026 software update for the Korean models of Galaxy S24, Galaxy S24 Ultra, Galaxy S24+, and Galaxy S24 FE smartphones. This flagship device will be the next to grab One UI 8.5 as a major software release.

Samsung Galaxy S24 series January 2026 software update is released in batches with One UI 8 version SKT and a package size of 383 megabytes. Your Samsung Galaxy S24 series phone will get up to 55 fixes with the January 2026 patch. 

This update provides that both Android and One UI systems remain secure. It also improves performance by clearing the system-level cache partition during installation.

Users of this phone can download this version with improved system security and better user experience. However, you should know that the software is released in batches and may take some time to reach all of the Samsung Galaxy S24 series users in the market.

You can download the latest software update on your Galaxy S24 series smartphone with the following instructions:

• Open Settings
• From here, now tap on Software update
• Click on Software update

You will be notified with updated information if an upgrade is available.

On the other hand, Samsung is also testing the One UI 8.5 update for dozens of Galaxy models. While the beta program is open to Galaxy S25 users, developers are ensuring that users of other phones don’t have to wait too long by conducting internal testing.

Samsung has started rolling out the January 2026 security update for more of its budget and mid-range phones. Now, two more devices, Samsung Galaxy M53 and Galaxy A06 4G, have joined the January 2026 security update.

The  Galaxy M53 is getting the January 2026 security update in Korea with the firmware version M536SKSSCGYL1. The Galaxy A06 4G is receiving it in Thailand, Malaysia, and Vietnam with version A065FXXS9CZA1.

Samsung’s January 2026 security patch includes up to 55 security fixes provided by Samsung, Google, and other partners. These fixes help protect the Galaxy phone from bugs, security risks, and any issues that might affect user privacy or performance.

However, the new update does not bring any new features or design changes. Instead, it focuses on improving stability and security.

If you have one of these devices, you can manually check for updates. Simply go to Settings > Software Update > Download and install. If an update is available, your phone will begin downloading it. Once the download is complete, tap Install now.
