Samsung has released firmware R630XXU0AZG2 for the Galaxy Buds3 Pro (model SM-R630). Samsung lists July 21, 2026, as the release date and describes the update as improving stability and reliability.
This is confirmed for the Buds3 Pro—not necessarily the standard Galaxy Buds3. The two models use separate firmware branches, so Buds3 owners should check their model before looking for this update.

This is a maintenance release rather than a feature update. There is no confirmed addition of new listening modes, Galaxy AI functions, head gestures, hearing-related capabilities, codecs, or features borrowed from newer Galaxy Buds models.
#1 Best Overall
- Compatibility & Battery Life: The Samsung Galaxy Buds 3 Pro are compatible with Android devices running Android 8.0 or later with at least 1.5GB RAM. They provide 5-8 hours of playback depending on Active Noise Cancellation (ANC) usage, and up to 18 hours with the charging case. The case supports wireless and wired charging, including Fast Charging technology for quick top-ups.
- Audio Features: Equipped with Bluetooth 5.4, the Buds 3 Pro support SSC HiFi and UHQ audio codecs, delivering 24bit/96KHz audio for superior sound quality. They also include 360 Audio with Direct Multi-Channel for an immersive listening experience, especially when paired with Galaxy devices.
- ANC & AI Features: The Buds 3 Pro feature improved Active Noise Cancellation (ANC) and advanced Galaxy AI, which enhances functionalities like real-time language translation, personalized sound profiles, and environment-based voice optimization. (Note: Galaxy AI features require a Samsung Galaxy device for full functionality).
- Call Features: With enhanced Super Wideband (SWB) microphones and AI-based noise reduction, the Buds 3 Pro improve call clarity by filtering out surrounding noise and reconstructing lost voice bits, ensuring clear and uninterrupted communication even in noisy environments.Water & Sweat Resistance: These earbuds are IPX7-rated for water resistance, making them more suitable for workouts and outdoor use in varying weather conditions.
- International Model without Domestic Warranty. Optimized Features: The Galaxy Buds 3 Pro are optimized for Android, particularly Samsung Galaxy devices, for advanced features such as 360 Audio, UHQ audio codecs, and real-time AI-based functionalities. While they are compatible with iOS devices via Bluetooth, certain features are exclusive to Galaxy Android devices.
Stability improvements can affect background behavior such as reconnection or general device reliability, but Samsung has not confirmed individual fixes. You may notice no obvious difference unless the update addresses a problem affecting your earbuds.
The available Samsung notice also does not provide a download size. Do not attach the previously reported approximately 8.28 MB size to this release; that figure referred to the earlier R630XXU0AZD2 firmware.
How to install R630XXU0AZG2
Samsung’s supported mobile update procedure is:
- Place both earbuds in the charging case.
- Leave the case lid open.
- Open Galaxy Wearable on your compatible phone or tablet.
- Tap Earbud settings.
- Tap Earbuds software update.
- Tap Download and install.
- Follow the on-screen instructions until the process finishes.
The earbuds may disconnect from the phone while the firmware installs. Samsung says they should reconnect automatically afterward. Keep the earbuds and case sufficiently charged, and avoid closing the case or interrupting the process unnecessarily.

If the mobile-app route is unavailable, Samsung says the Galaxy Buds PC app supports both the Galaxy Buds3 and Galaxy Buds3 Pro.
How to check your current firmware
Connect the earbuds in Galaxy Wearable, select them, and open the earbuds’ settings or software-update screen. Look for the earbud firmware entry and compare it with the applicable build.
For the Pro model, the relevant identifier begins with R630. Do not confuse it with the Galaxy Wearable app version or your phone’s One UI and Android version—those are separate software versions.
Rank #3

Menu wording can vary slightly with the phone’s software and the installed Galaxy Wearable version. If necessary, update Galaxy Wearable through your phone’s app store before checking again.
What standard Galaxy Buds3 owners need to know
The standard Galaxy Buds3 uses model number SM-R530 and a separate R530 firmware branch. Samsung’s indexed firmware record lists R530XXU0AYG3, released May 13, 2026, as the latest listed standard Buds3 build—not R630XXU0AZG2.
In other words, do not treat the Pro firmware as an update for standard Buds3 earbuds. Check the model shown in Galaxy Wearable or on the product packaging before comparing firmware numbers.

Why the update may not appear
Samsung firmware availability can vary by country, model variant, network environment, and rollout timing. A release listed on Samsung’s firmware site is not a guarantee that every owner will receive it simultaneously, including owners in the United States.
If your Galaxy Buds3 Pro does not show the update, work through these checks:
Free tools Windows power users keep installed
One-click scans. No signup required.
- Confirm both earbuds are correctly seated in the charging case.
- Leave the case open while checking for the update.
- Charge the earbuds and case.
- Confirm the earbuds are connected in Galaxy Wearable.
- Update the Galaxy Wearable app.
- Disconnect and reconnect, or re-pair, the earbuds.
- Try the Galaxy Buds PC app if the phone app still does not offer the update.
- If everything is working and the build is not offered, wait for the rollout to reach your region.
Samsung’s consumer instructions describe updating through Galaxy Wearable or the PC manager. They do not provide a consumer process for manually flashing or sideloading earbud firmware, so unofficial firmware tools are not a recommended workaround.
Should you install it?
Yes, if Galaxy Wearable offers R630XXU0AZG2 normally for your Galaxy Buds3 Pro. Stability and reliability updates are generally worth installing, particularly if you have experienced intermittent pairing, playback, charging, or call problems. However, Samsung’s changelog does not guarantee a fix for any one of those issues, and the update should not be treated as a promised improvement to sound, ANC, or battery life.
After installation, test the functions that matter to you—Bluetooth reconnection, media playback, charging, ANC, and microphone performance. If pairing problems or other symptoms appear, restart the earbuds and phone, reconnect the earbuds, and contact Samsung support or use Samsung Members if the issue continues.
