Overview
- Samsung is expanding the March 2026 security update to more Galaxy S23 and S24 units in additional markets, with India included and some US S24 variants still waiting for their turn.
- Midrange models are in the queue as well, with the Galaxy A36 rollout starting internationally from Vietnam and the Galaxy A55 and A56 picking up the patch in India before a broader release.
- The March package fixes 65 vulnerabilities across Android and Samsung components, closing holes that could allow data theft, unauthorized access, or device compromise.
- The Galaxy S26 received an early April security update in Korea with build AZCL at roughly 547MB, and Samsung has not yet published a changelog for the contents.
- A separate Google Play System update dated March 1, 2026 is also showing up on Galaxy phones such as the S26 and S23 in India, which updates core Google services in the background without a full OS upgrade.
