Samsung Galaxy A54 Gets October 2026 Security Update With 62 Fixes

Samsung has begun rolling out the October 2026 security update to the Galaxy A54. It carries fixes for 62 known software issues and is currently available for the international variant in Thailand (firmware A546EXXSNFZJ3). The company has also opened the One UI 9.0 beta program for A54 users — separate from the security patch, and not yet on a defined rollout timeline.
