Samsung has initiated internal testing on a new software build for its flagship Galaxy S26 Ultra, signalling that the next major maintenance update is well underway.
According to details spotted on Samsung's test servers by tech insider Tarun Vats, the new One UI 8.5 firmware, labelled S948BXXU4AZG7, succeeds the previous July rollout.
