Seamless updates in Android, also known as A/B system updates, ensure a functional bootable system remains on the device during an over-the-air (OTA) update2. This method reduces the likelihood of an inactive device after an update, leading to fewer device replacements and reflashes at repair centers2. Seamless updates work by having two different system partitions on the phone, allowing unpacking and transferring during one system partition's use, providing an uninterrupted user experience4.

Seamless updates in Android devices refer to a feature that allows updates to be installed on one system partition while users can continue using their phones on the other partition without interruptions. This eliminates the need for users to reboot their phones and wait for the update to complete, providing a more convenient and efficient update experience.

Seamless updates improve user experience by allowing new firmware to be installed in the background without interrupting the user. This means users can continue to use their phone during the update process and only need to reboot once the update is complete, without waiting for lengthy progress bars. This is a quality-of-life improvement, especially for devices that receive regular security updates.
