A leaked One UI 8.5 build has early signs of the Galaxy Buds4 and Buds4 Pro, as per AndroidAuthority. The software build listed SM-R540 and SM-R640, which would be announced as the Buds4 and Buds4 Pro.

While the One UI 8.5 build didn’t list the products by their names, the model numbers refer to the next generation. To be noted, the Galaxy Buds3 and Buds3 Pro carry model numbers SM-R530 and SM-R630.

In addition to the emergence of model numbers, software testing has also begun.

Firmware testing kicked off

As discovered by Alfaturk, Samsung has started testing a new firmware with build version R640XXU0AYI1. The model number confirms it’s being developed for the upcoming Galaxy Buds4 Pro earbuds.

It’s a regular process that takes place before the product unveiling. The build version’s last alphanumeric digits will change throughout the testing period as the company’s developers bring refinements.
