Android has two update mechanisms: A/B (seamless) update and non-A/B update. Android 11 joins these two mechanisms to reduce code complexity and enhance update ability. The new update mechanism Virtual A/B combines the advantages of the two predecessors by seamlessly updating all devices without reducing storage costs.

  • Virtual A/B updates are as seamless as A/B updates. Virtual A/B updates can minimize the time that devices are offline and unavailable.
  • Virtual A/B updates can be rolled back. If the new operating system fails to start, the device will automatically roll back to the previous version.
  • Virtual A/B update uses minimal additional space by copying only the partition used by the bootloader. Other updateable partitions have been snapshotted.

A/B partitions put basic files into “partitions” on the device. Meanwhile, after installing the update, the device will update the files in partition B while leaving the phone in partition A.

Users can update the inactive partition B to the next version of Android until the user restarts and the device switches from slot A to partition B, leaving it on the newer version of Android.

It makes the update process almost completely in the background. Users can continue to use their phone while installing the update. If your phone is updated frequently, this feature called seamless update.

If an update is accidentally damaged and cannot be installed, the A/B partition in Android can provide protection. In this case, only the inactive partition – Partition B will be affected, so users can continue to use their phones normally.

The seamless updates are a huge success at the expense of storage capacity. But this storage space strategy is still not accepted by some companies. For example, Samsung, which will take up to 3GB of additional storage space on the device.

Since Android 11 devices adopt mandatory A/B partitioning, seamless updates may also become more common. In turn, this may also help Android users update their devices more frequently, as it will take less time.
