Samsung has released the first software update for its newest wireless earbuds, the Galaxy Buds 4 and Galaxy Buds 4 Pro. The update brings improved reliability and stability to the earbuds.
A software update with firmware version R640XXU0AZD2 and a download size of around 8MB is rolling out to the Galaxy Buds 4 Pro in South Korea. The Galaxy Buds 4 will likely receive a similar update with firmware version R540XXU0AZD2.
Based on the official changelog, the update only brings reliability and stability improvements. It could fix a few bugs the company may have discovered since the earbuds launched.
Currently, the update is only available in South Korea. However, it could roll out globally within the next few days.
