Summary
(AI)
The US rollout followed a messy schedule. Samsung’s Thailand newsroom first moved the date from September 21 to September 28, then dropped specific dates, before the update began reaching phones around September 22 to 23.
Some users also reported a bug that puts the lock screen clock in the wrong place, which seems tied to the Good Lock app. Samsung has acknowledged it but has not given a timeline for a fix.
