Samsung has released the March 2025 security update for select Galaxy A53 devices in South and North America, including Bolivia, Peru, and Mexico. The update is rolling out over-the-air (OTA) via phone settings and can also be downloaded through Samsung’s firmware archive.
The March 2025 security patch addresses 58 previously discovered vulnerabilities, with 51 coming from Google and the remaining 7 from Samsung. Owners of the Galaxy A53 can check for the update by looking for the build number A536EXXSDEYBD in their phone’s software update menu.
This update is a precursor to the highly anticipated One UI 7 (Android 15) release, expected to start on April 7 for select flagships and potentially mid-range devices like the Galaxy A53 in May. The device will receive four major OS upgrades and security updates for at least another year after exhausting those options.
