Overview
- Samsung began releasing the first firmware Tuesday in South Korea for the Galaxy Buds 4 Pro under version R640XXU0AZD2 at roughly 8MB.
- Samsung’s official notes state the update applies stabilization code and adds no new features.
- The base Galaxy Buds 4 are expected to get a similar patch soon, likely labeled R540XXU0AZD2, though reports have not confirmed the file yet.
- Users must install through the Galaxy Wearable app, during which the earbuds are unavailable and some settings may change.
- The rollout follows a brief pause last week after some users reported downloads would not install, an issue that now appears resolved in the resumed release.
