Earlier today, I reported how Samsung is internally testing the One UI 4.0 beta on Galaxy S21 series in China. We already know that the company will release the beta program later this month across various regions. However, a confirmed list of regions is still missing. Well, Samsung has gone ahead and confirmed that the Android 12-based One UI 4.0 is definitely hitting on the Galaxy S21 device in Germany, and while there is no specific date, this certainly is a good idea.

The confirmation is coming straight from Samsung on their community forums, and the company has said that the beta will be coming to all Galaxy S21 devices "soon." Again, the exact date is still missing at the time of writing, but based on the details that have been revealed in the past, this could take place in September, at the very least.
