In early May, Samsung introduced One UI 5 Watch, and shortly thereafter, Google officially unveiled the Wear OS 4 platform. Last month, Samsung launched its latest smartwatches, the Galaxy Watch6 and Galaxy Watch6 Classic, equipped with both Wear OS 4 and One UI 5 Watch. During this period, the Korean tech giant has also been diligently preparing software updates for its older wearable devices.

Today, it's time for the 2021 models, the Galaxy Watch4 and Galaxy Watch4 Classic, to receive their own dose of this fresh release. The rollout has already commenced in the United States, with the new firmware versions identified as R870XXU1HWH3 for the Watch4 and R890XXU1HWH3 for the Watch4 Classic. These updates include the security patch level for July 2023.

The changelog is massive, so if you want to go through it all please head on over to the Source linked below. We'll only mention some important highlights, chief among which is the ability to transfer your watch to a new phone without a reset - or with a reset and a proper restoration of data, the wording is unclear, but either way, that's a much better situation than the one we had before.

Next up, more call controls: you can adjust the call volume, mute sound, and press buttons on the keypad all from your watch. Bixby can read your notifications out loud if you have headphones connected to your watch (but only if it's set as the default voice assistant for your watch), there's support for app folders, and you can control the wearable without touching it by assigning actions to gestures like shaking your wrist, making a fist, or pinching your fingers.

You can check the battery level of your watch, phone, and Galaxy Buds, and for the Buds you can turn 360 audio on and off from the controller tile, and an album or story can be set as your watch face. It will cycle through items every time you turn on the watch screen.

Samsung Health gets enhanced sleep coaching, the ability to automatically record cycling workouts, customized exercise creation, more accurate results for track runs, and it can provide personalized heart rate zones while you run.

As always, the update is most likely going out in stages, meaning it could take a while before it reaches all of the devices out there in the wild.
