Security Tracker
Samsung Galaxy Security Updates
Samsung issues regular security patches for Galaxy devices based on the Android Security Bulletin and Samsung's own Mobile Security Bulletin. These patches address vulnerabilities in the Android framework, Samsung-specific components, and device drivers. Supported flagship devices typically receive monthly security patches, while many mid-range devices receive quarterly patches.
Each security update is identified by its security patch level — a date string (e.g. 2026-08-01) that indicates which vulnerabilities have been addressed. You can find your device's current patch level in Settings > About phone > Software information.
This independent tracker monitors security patch releases across the Galaxy lineup and labels each record as Verified, Reported, or Expected.
Monthly vs quarterly patches
Samsung categorises devices into monthly, quarterly, and biannual security update schedules. Flagship devices like the Galaxy S series and Galaxy Z series typically receive monthly patches. Many Galaxy A series devices receive quarterly patches. The update frequency is determined by Samsung's security policy for each device model and may change as a device ages.
Samsung security bulletins
Samsung publishes a monthly Mobile Security Bulletin describing the vulnerabilities addressed in each patch. The bulletin covers both Google's Android security fixes and Samsung-specific fixes for components like Knox, Exynos, and Samsung apps. The security patch level date in your device's software information corresponds to the bulletin month your device is currently running.
Understanding patch levels
The security patch level is a date string (e.g. 2026-08-01) that indicates the latest security bulletin your device has applied. A patch level of 2026-08-01 means your device includes all security fixes from the August 2026 Samsung Mobile Security Bulletin and all prior months. A newer patch level generally means better protection against known vulnerabilities.
