Samsung Galaxy firmware security updates can include both Google’s Android security patches and fixes for Samsung-specific vulnerabilities. To check what is installed, open Settings > Software update and look for Last update or System Update history; then check Settings > About phone > Software information for your phone’s software details. Menu names vary by model and software version.
What Samsung security updates fix
Samsung firmware security updates, which Samsung calls Security Maintenance Releases (SMRs), can combine patches for Android operating-system vulnerabilities released by Google with fixes for Samsung-specific issues. Samsung describes this scope on its security update policy page.
Samsung’s security bulletins identify issues using Google CVEs (Common Vulnerabilities and Exposures) and Samsung SVEs (Samsung Vulnerabilities and Exposures). A release may also list patches from Samsung Semiconductor. Entries can carry critical, high, moderate, or low severity labels, and the bulletin may note that an issue was already addressed in an earlier update or does not apply to Samsung devices.

How to check the update information on your Galaxy phone
- Open the update history. Go to Settings > Software update (called System updates on some devices), then look for Last update or System Update history. Some versions offer a Learn more link with details about an update.
- Check the installed software details. Go to Settings > About phone (or About tablet) > Software information. This screen can show your One UI version, Android version, and build number.
- Look for the security-update control if available. On supported interfaces, Samsung documents Settings > Security and privacy > Updates > Security update. The path and available controls depend on the device and software version.
- Compare with the relevant Samsung bulletin. Find the SMR for the month and year you are checking. Review its Google CVE, Samsung SVE, and any chipset or vendor sections, including notes about applicability or release timing. Samsung identifies its Samsung security index (SSI) under Security software version; use the phone’s displayed information and the bulletin together, without assuming that every entry applies to every model. Samsung directs readers to Android Security Bulletins for more detail about Google patches.
Samsung’s support instructions explain that labels and options can differ by model and software version. The update history and software information answer different questions: the history describes update activity, while Software information describes the currently installed software.
Firmware patches and app fixes use different update paths
A firmware SMR addresses device software and platform vulnerabilities. Security fixes for Samsung apps and services can be delivered separately through official app marketplaces, including Galaxy Store and Google Play Store. Samsung lists affected and resolved app versions in its Other Updates service bulletin.

- Please note, this device does not support E-SIM; This 4G model is compatible with all GSM networks worldwide outside of the U.S. In the US, ONLY compatible with T-Mobile and their MVNO's (Metro and Standup). It will NOT work with other CDMA carriers, and it is also not compatible with their MVNO (Visible, Xfinity Mobile, US Mobile, Cricket Wireless, etc).
- Compatibility with certain third-party devices and accessibility accessories, including some hearing aids, may vary depending on manufacturer support, Bluetooth protocols, software compatibility, and regional firmware limitations. For additional hearing aid compatibility information, please refer to Samsung’s official support documentation.

For example, Samsung’s bulletin published October 6, 2026 lists Samsung Internet version 30.0.5.24 as the resolved version for an input-validation issue identified as SVE-2026-2694/CVE-2026-21132. That is an app-version fix; it does not establish the firmware patch level installed on any particular Galaxy phone.

Samsung says selected devices are assigned monthly, quarterly, or biannual firmware security update schedules. Its policy states that, as of January 2024, it was extending security update support for Galaxy devices by up to seven years. “Up to” describes the maximum support-policy duration, not a promise that every device gets monthly updates throughout that period. Samsung’s policy page says the supported-device list may change as support periods expire.

- A regular operating-system upgrade can delay a planned security patch; Samsung says the OS upgrade will include up-to-date security patches when it is delivered.
- Some chipset-vendor or device-specific patches may not be ready for that month’s package and can arrive in a later package.
- A Samsung SVE may already have been included in an earlier release, so a current bulletin is not necessarily the first update containing its fix.
For a particular handset, use its update history and software information alongside Samsung’s current device and release information. A bulletin’s month is not a universal rollout date for all Galaxy phones.
