The rumors were true – Samsung’s flagship smartphone line finally supports seamless updates, with the release of the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra. The Korean company has been a holdout for many, many years, and finally implemented the functionality in the Galaxy A55 last year.
We assume that was meant to test the waters, and apparently everything has been fine with the A55, so now the feature finally made its way to the S line. What “seamless updates” means is that your device will be unavailable to use for less time when it’s updating.
That’s because the update is applied while the device is on, and it’s installed on a different partition than the one the OS is currently using. Then, when installation is complete, you are prompted to reboot the device, at which point it boots from the newly updated software. This means the reboot process itself is much quicker, as it’s basically just a tad longer than a normal reboot.
Whereas before, without seamless updates, you’d need to wait for the software to be installed without being able to use your phone while it was doing that. So this is one of those small quality-of-life improvements that won’t be front and center on any store display, but are welcome nevertheless. The only weird thing about this is how it took Samsung more than eight years to hop on the bandwagon (Google introduced seamless updates in Android in 2016).
