Samsung Galaxy S25 leaks: Samsung’s upcoming Galaxy S25 series, due in early 2024, could be the brand’s first flagship range to introduce seamless firmware updates via an A/B partition system. This feature, known for improving user experience during updates, has been around since 2016, when Google first rolled it out. However, Samsung has been slow to adopt it in its flagship devices so far.

Rumors from tech leaks suggest that the Galaxy S25 could follow the lead of Samsung’s Galaxy A55, which launched earlier this year as the first Samsung device to feature the A/B partition structure.

What does A/B partition mean? What are its advantages?

This design allows the phone to install software updates in the background on a separate “B” partition while the user continues to use their device on the active “A” partition (or vice versa).

When the update is ready, a simple reboot switches to the new software on the secondary partition, making update times almost transparent. This system reduces wait times and restarts faster, which could be a game-changer for the Galaxy S25 and future flagship devices.

This new approach not only reduces boot times after updating, but also provides a smoother experience by enabling uninterrupted updates. Previously, Samsung’s approach required users to pause their activities while installing firmware updates. With the A/B system, premium Samsung users could benefit from a more efficient update process, likely setting a trend for upcoming high-end Samsung models.

Another key aspect of this feature is that it must be implemented at the hardware level, as the A/B partition cannot be installed later via a software update. Devices must be designed with this dual partition system from the start, so if Samsung brings this feature to the Galaxy S25 series, it could indicate a broader commitment to seamless updates on future devices. This transition to A/B partitions could ultimately make Samsung’s ecosystem more aligned with Google’s latest Android features.
