Android 11: Google is looking to make A/B allotments compulsory to make the update procedure quicker, smoother and more secure. Another submit in the AOSP Gerrit, titled ‘Require Virtual A/B on R launches’’, suggests that Android 11 will check whether the device supports A/B segments each time before it boots. Originally introduced in Android 7.0 Nougat, A/B segments take into consideration consistent updates, yet in addition shields phones from bricking in case of failed updates.
As explained by Google, the A/B setup refers to copied allotments containing the system picture, the boot picture and then some. Devices with copied A/B partitions take into account a consistent update process, as the inactive segment containing an indistinguishable system picture is updated in the background while the device remains usable, on account of the dynamic segment that contains the working system picture. Be that as it may, devices without A/B allotments lock users out of the phone during the update procedure.
If the update is successful, the two partitions swap positions after a reboot, transforming the erstwhile inactive partition into the active partition with the latest software. However, in case of a failed update, the device can still boot using the old active partition, saving users from the hassle of having to deal with a bricked phone.
With A/B partitions becoming mandatory in Android 11 devices, seamless updates are likely to become more commonplace, but do note that the change has just been added to the AOSP Gerrit and, is yet to be implemented in Android 11 DP2, so it will be interesting to see when it will be available in an official Android build.
