• Galaxy Watch4 40mm (BT and Cellular, SM-R860/R865x): JYL6 [KOO]

• Galaxy Watch4 Classic 44mm (BT and Cellular, SM-R890/R895x): JYL6 [KOO]

You can now update your smartwatch, but if you still didn’t receive any update, you’ll have to wait for a few days as this rollout is a gradual rollout that starts from Korea. You can periodically check for updates to see if this update has reached your device. We recommend that you update your watch manager in your phone to ensure compatibility with the latest software.

To update your watch, follow these steps:

• With your phone
• Open Galaxy Wearable
• Select your watch
• Open Watch settings
• Navigate to Software Update
• Tap Download and Install
• Wait until the update shows up, then press Download
• Wait until the update gets downloaded and copied to your watch, then press Install
• With your watch
• Open Settings
• Navigate to Software update
• Tap Download and Install
• Wait until the update shows up, then press Download
• Wait until it gets downloaded to your watch, then press Install

In an event that something went wrong with copying the update, disconnect your phone from your watch by turning Bluetooth off or by disconnecting it through Galaxy Wearable, then try again from your watch. Make sure to turn Wi-Fi on in your watch to download the update faster.

Make sure that both your phone and your watch are charged before performing the update, and that your internet connection is stable. Never interrupt the update process, or there could be problems later. The update process may take a few minutes to finish, and if it appears to be stuck, just wait for more minutes.

Samsung pulls One UI 8 Watch update for the Galaxy Watch4 and Watch5 as users report issues

A few days after One UI 8 Watch was released for the Galaxy Watch4 and Watch5 users worldwide, they began noticing problems with the watch that were rather serious. Those problems affect normal operation of the watch, and are severe enough that Samsung has started pulling the Galaxy Watch4 and the Watch5 update, starting from the Korean servers, as confirmed by this thread. Earlier, the update was identified as JYK4, which suggests that it was built on November.

An Indian user who updated their Galaxy Watch4 have reported issues with their smartwatch on Samsung Members after they’ve updated their watch to the One UI 8 Watch software, impairing the normal operation of the watch. More specifically, the sensors on the Galaxy Watch4 have begun malfunctioning after the update, such as the wrist detection sensor, which is crucial for any smartwatch. Alongside that, the BIA sensor and the ECG sensor were also not working properly, telling the user that their placement was incorrect. What makes it worse was that even after the reset, the watch still malfunctioned.

To make matters worse, some users reported that they’re not getting the One UI 8 Watch update on their Galaxy Watch4 smartwatches, despite being eligible for the update, and the LTE version users are still waiting for the update in countries like India, USA, and Korea.

Until Samsung pushes the revised version of the Galaxy Watch4 and the Watch5 update, if you haven’t updated your smartwatch, it’s recommended that you hold the update until a newer version is released. You can identify this newer version with either the JYL? build or the JZA? build.
