As you likely heard by now, the stable One UI 7 update for the Galaxy S24, Galaxy Z Flip 6, and Galaxy Z Fold 6 hasn't been without issues. In a rare event, Samsung pulled the update from its servers due to unconfirmed flaws. How could this happen?

Nobody knows exactly, but we suspect it might have something to do with the fact that Samsung didn't properly test One UI 7 soon enough and lacked the necessary user feedback due to its own limited and slow beta expansion.

The entire One UI 7 rollout schedule has been a mess, from beta to stable, and one thing that stands out compared to previous successful One UI beta programs is the smaller pool of testers Samsung worked with to receive feedback for One UI 7.

Here is the perfect example of what we're trying to convey. Samsung released the first One UI 6.0 beta update for the Galaxy S23 series in August 2023. It took just one month for the Galaxy S21 and Galaxy S22 lineups to join One UI 6 beta testing in September.

Then, the Galaxy Z Fold 5 and Z Flip 5, along with the Galaxy Z Flip 4 and Z Fold 4, entered One UI 6.0 beta testing at the beginning of October.

Samsung even started testing One UI 6.0 beta on the Galaxy A34, A53, and A54 in September 2023, while the cheaper Galaxy F23, Galaxy M23, and A52s joined in October 2023.

This gave Samsung ample time to test the One UI 6.0 beta with the help of more Galaxy device users a lot earlier and iron out the kinks.

In contrast to One UI 6.0, Samsung released the first One UI 7.0 beta firmware for the Galaxy S24 in December 2024 and waited until March 2025 to bring the update to the Galaxy S23, the Galaxy Z Fold 6, and the Galaxy Z Flip 6.

Needless to say, for One UI 6.0, Samsung had way more data points and greater help from countless Galaxy device users who offered feedback from a more diverse pool of Galaxy phones.

This could explain why One UI 6.0 was a fairly solid update once it went stable and why Samsung is having so many difficulties with One UI 7.

It's a theory, but whether or not it holds the answer, nothing can change the fact that Samsung botched One UI 7 during beta testing and after the first stable build went out. We can only hope the company will do better next time and learn from its past success stories and mistakes.

Countless Galaxy device users in many markets are always eager to join Samsung's beta programs, yet for One UI 7.0, the company didn't give many of its fans much of a choice.
