Samsung is finally working to bring Seamless Updates to its phones. The feature, which premiered on Pixels in 2016, and is found in many Android phones is yet to come to Galaxies. It allows for an update to be installed on partition B while you use your phone in partition A, then when the update is done you just need to restart, instead of having your phone unavailable for the entirety of the process.
Samsung is working on adding Seamless Updates as part of OneUI 6 next year, per an interview with Samsung Electronics VP Hyesoon Jeong (Sally).
Google has made Seamless Updates a mandatory feature for any phone that launches with Android 13 so it would be viable to expect the Galaxy S23 series to have the feature even before OneUI 6 arrives later next year. We’ll see.
Finally, in the interview, Sally said that OneUI won’t branch out from phones to Chromebooks and TVs.
