Following last week’s initial rollout in South Korea, Samsung is now seeding its One UI 7 update to the Galaxy A15 across more regions, including Asia, Europe and North America.

The update comes bearing the A155FXXU6CYE3/A155MUBU6CYE3 identifiers and weighs in at around 3GB. Users are also getting the May 2025 security patch.
