Although stable One UI 8 is just starting to arrive on Galaxy devices, Samsung is already working on One UI 8.5. That update appears to have leaked, as some people are digging into an alleged modified build. In a tip sent to Android Authority, the code within that build seems to provide the very first reference to the Galaxy Buds 4 and Galaxy Buds 4 Pro.

But this leak doesn’t only give us a confirmation on the product names. Additional strings of code may have revealed the model numbers for both pairs of earbuds. According to that code, the Galaxy Buds 4 come with the model number SM-R540. Meanwhile, the Galaxy Buds 4 Pro feature the model number SM-R640.
