In fact, it already did a dry run with the Galaxy A55 that is its first phone to support the Seamless Update option. According to a reliable leakster, Samsung will indeed bring the faster, safer, seamless Android update option to the Galaxy S25, Galaxy S25 Plus and Galaxy S25 Ultra, making them its first flagship phones to support it.

For reference, the Samsung Galaxy S24 Ultra is 162.3 x 79 x 8.6mm, so that would make the Samsung Galaxy S25 Ultra a tiny bit taller, but narrower and thinner. We’ve also heard that the Galaxy S25 Ultra might be lighter at 219g, rather than the 232g of its predecessor.

Samsung Galaxy S25 could finally introduce Android's seamless updates, over eight years after its launch. Currently, only the Galaxy A55 supports seamless updates, although the smartphone is unavailable in the US. The Galaxy S25 series could debut by mid-January, based on the announcement date of the Galaxy S24 flagships earlier this year.
