It looks like the unknowns about One UI 7, compatible mobile phones and dates are starting to fade. A few days ago we told you which of the 23 Samsungs would be the first to update to the new software, and today we can tell you when will this event happen. Indirectly, the company has almost confirmed the arrival and availability of the first phase of testing.
And this is what Samsung Developer Conference was scheduled in South Korea for this day November 21. This event is similar to Apple WWDC, but it is focused on revealing news from the big S software ecosystem. However, the company has not confirmed anything that it will show at this conference, so everything is based on speculation.
And, of course, the first big bet is to see One UI 7 and all new programs for your mobile phones.. It would be extremely strange if Samsung did not reveal anything about its level of customization. In fact, it’s likely that the entire event will revolve around him, being the main protagonist and giving way to other small details about the device ecosystem and opportunities for developers.
November 21, beta testing day
Once again, we are faced with an assumption based on rumors and leaks, which does not have much weight, but fits perfectly into the company’s strategy of past years. After the presentation of One UI 7 and all the new features, Samsung may announce first beta release on the same dayNovember 21st.
This is similar to what Apple is doing with iOS and will allow users download One UI 7 beta the same day to start playing with your news. What devices will be able to access? Last week, we informed you that a preliminary list of 23 mobile phones has been compiled in the first phase. They are as follows.
- Galaxy S24
- Galaxy S24+
- Galaxy S24 Ultra
- Galaxy S24 FE
- Galaxy S23
- Galaxy S23+

For everyone? Well, that’s something we don’t know yet. Initially, if the strategy we are discussing goes ahead, some sources say that on launch day the beta version will only be available in South Korea and the US. That is, that Europe and the rest of the world will have to wait to a more advanced version testing phase.
This makes sense, and Samsung’s newspaper library tells us it’s highly likely. In other years, the One UI beta has taken longer to reach Europe, although it is also true that its arrival usually comes after a couple of important updates. leaving much more advanced software for users who decide to give it a try.

If you don’t want the beta, you’ll have to wait to get One UI 7.
That’s right, if you prefer not to deal with trials, bugs and some glitches, you’ll have to wait. One UI 7 has already been delayed several times and the latest leaks say that version stable and official could arrive early 2025. In fact, it’s likely that Samsung will decide to launch it alongside the Galaxy S25, a trio of handsets that should be released in the first half of January.
