Samsung rolled out its first firmware patch for the Galaxy Buds 4 Pro this week, targeting the South Korean market. The R640XXU0AZD2 package clocks in at 8.55 MB and promises minor stability tweaks, chiefly around Bluetooth connectivity and battery reporting. Users who paired the earbuds after the initial launch should see smoother handoffs between devices once the update installs via OTA, no cable needed, making the process painless.

The update arrives a month after the Buds 4 Pro debuted, a premium offering that competes with Apple’s AirPods Pro 2 and Sony’s WF‑1000XM4. While the hardware boasts active noise cancellation, a 6‑hour playback core and a compact charging case, early adopters reported occasional dropouts, prompting Samsung to push this quick fix for early buyers.

Because the patch is small, Samsung expects it to roll out to additional regions within days, and the same binary will soon be applied to the standard Galaxy Buds 4 line. For consumers, the fix means the premium earbuds can finally deliver the reliable, on‑the‑go experience Samsung promised, and keep the warranty intact.
