Samsung Galaxy S25 series could be the company’s first flagships to get seamless updates

The Samsung Galaxy A55 5G isn’t just another offering in the company’s popular A-series lineup of mid-range smartphones. It also happens to be the first (and only) Samsung smartphone that gets an A/B system partition feature. In other words, seamless updates.

Not for much longer though, as it turns out. This is because new reports suggest that seamless updates may (finally) be making their way to the company’s flagship S-series of smartphones next year. Read on.

Samsung Galaxy S25 series to get seamless updates: What's there to know?

Tipster chunvn8888, in a post on X (formerly Twitter), claims that the upcoming S-series of flagship smartphones could get A/B or seamless updates. These will include everything from minor security patches to major updates.

The upcoming smartphones (likely to be called the Galaxy S25 series) are expected to be launched sometime in January or February next year if Samsung’s usual launch timeline from previous years is anything to go by.

Interestingly, A/B updates for Android smartphones were introduced by Google as long ago as 2016. So, Samsung seems to be playing catch-up here. Moreover, if and when the feature will be introduced for other offerings in the A-series lineup, the Galaxy Z series of foldable smartphones, and the more budget Galaxy M, and F-series of smartphones, remains to be seen as of yet.

What are A/B, or seamless updates, and how do they work?

A/B refers to the way a new software update (B) is downloaded and set up on a separate partition in any given smartphone’s memory, while the current software (A) continues running on another partition.

This, in essence, allows you to continue using your smartphone while it updates itself. Of course, a reboot is still required to apply the update, but it generally tends to be a lot quicker in the case of seamless updates. This is because most of the installation was already done in the background.

Another thing to note here is also the fact that the feature cannot be enabled merely through a firmware update (even though it did arrive with One UI 6.1 on the Samsung Galaxy A55 5G). A smartphone has to be manufactured with an A/B system partition structure, or else it won’t ever support the feature.
