Samsung has published the June Galaxy security patch details, and it is a busy one: 45 vulnerabilities are being addressed, including five rated critical. The update is already part of the One UI 9.0 beta for Galaxy S26 phones in some countries, while broader availability for supported Galaxy phones and tablets is expected in the coming weeks.
The split is familiar but still telling. Thirty-three of the fixes cover Android issues shared with Google, while 12 are Samsung-specific problems tucked inside parts of One UI that many users never think about until something breaks: Smart Suggestions, Samsung Account, Samsung Cloud, Theme Manager, system settings, and more. Most of the bugs affected devices running Android 14, Android 15, and Android 16.
What Samsung fixed in June
- 45 total vulnerabilities fixed
- 33 Android-related issues patched with Google
- 5 of those Android flaws were rated critical
- 12 Samsung-specific fixes across One UI components
- One fix addresses a DRM HDR driver issue for Exynos platforms
That mix says something about modern phone security: the risk is rarely just the operating system, because the vendor layer keeps growing its own attack surface. Samsung is hardly alone here, but when a patch list spans account services, cloud tools, visual theming, and hardware drivers, it is a reminder that ”phone security” now includes a lot more than Android itself.
Galaxy S26 beta gets the June patch first
The June patch has already landed in the beta build of One UI 9.0 for the Galaxy S26 series in select markets. That is the usual premium-device privilege: testers and newer hardware get the fixes first, while the rest of the Galaxy lineup waits its turn. For everyone else, the rollout should begin in the next few weeks if Samsung sticks to its normal update cadence.
The Exynos DRM HDR driver fix is another small but useful detail. Security patches often sound abstract until they touch display, media, or connectivity components that sit close to the hardware. Those are exactly the kinds of bugs vendors prefer to close quietly before users ever notice them.
What to expect next for Galaxy phones and tablets
If Samsung follows its recent pattern, the patch will move from beta devices to mainstream flagships and then to older supported Galaxy phones and tablets. The question is less whether the update will arrive than how fast it will spread across regions and carrier variants, the part of Android updating that always manages to be more tedious than it should be.
