Apple’s watchOS 27.0.1 update has arrived with a fix that prevents Apple Watch Ultra 4 and Apple Watch Series 12 models from randomly restarting.
New Apple Watch models could encounter restarts during use
On Wednesday, just over a week after watchOS 27.0 reached the general public, Apple deployed the watchOS 27.0.1 update. The software addresses a bug that caused the Apple Watch Series 12 and Apple Watch Ultra 4 to restart unexpectedly.
Those who encountered the now-resolved issue said their Apple Watch rebooted while editing watch faces, making calls, using Siri AI, opening Apple Maps or the App Store, and recording workouts. Some Apple Watch owners have even said their devices restarted when idle.
