Samsung Galaxy A54 gets October 2026 security update — 62 fixes, OTA rolling out in Thailand first. Firmware version A546EXXSNFZJ3. No severity details disclosed. One UI 9.0 beta now open for A54 users, separate from the security patch, and not yet tied to a rollout schedule.
Android 17 under the hood, but Samsung hasn’t confirmed stable release timing for the full OS upgrade. The A54 is receiving this month’s patch ahead of the newer Galaxy A57. An unusual priority call for a mid-range device launched in early 2023. The update is live for international variants in Thailand.
Other regions haven’t been named. Samsung says eligible models will get it “in the coming days.” No US or India pricing or availability mentioned, because this is a software update, not a new device. No hardware changes. No camera tweaks.
