All Android 13 devices may feature Virtual A/B . support



Google is said to enforce default A/B support for GMS licensing on devices launched with Android 13. Thanks to this, Android 13 launchers from manufacturers like Samsung and Oppo can finally feature seamless update support, after several years of being late to the competition.

For those unaware, Google introduced an A/B split scheme with Android 7.0 Nougat to speed up software updates. The company added support for copying certain sections into Section A and Section B. Your active partition is the partition you’re currently using, and the inactive partition can be refreshed in the background and then switched to with a quick restart.

This implementation makes software updates noticeably faster on Android devices. However, some OEMs have not yet adopted this approach. Samsung devices, for example, do not have A/B partitions and take longer to apply software updates, making the devices unusable for several minutes. Google is now aiming to change that by making virtual A/B support mandatory for GMS licensing on devices running Android 13.

Google previously attempted to enforce virtual A/B support on all devices running Android 11. However, the company has rolled back the requirements and updated the Android 11 Compatibility Definition Document (CDD) to recommend that A/B system updates be supported, but not enforced. . As a result, some Android OEMs still have to implement virtual A/B support, thus supporting seamless updates on their devices.

Football Highlights

While Android 13 CDD Still does not require OEMs to provide virtual A/B supporta new report from esper It reveals that Google is now requiring it to obtain a GMS license on devices running Android 13. To this end, the company has Added new tests To Vendor Test Suite (VTS) that makes default A/B support mandatory for devices running Android 13.

The report notes that although these tests were combined before the launch of Android 13, they It remains in place even after its launch, unlike during the development of Android 11.” This means that all devices running Android 13 must pass these tests to get GMS certification.

In fact, Google will require OEMs to release devices running Android 13 to offer virtual A/B support if they wish to offer Google Mobile Services. The only exception, like esper notes, is “Android 13 devices shipped with older vendor software, thanks to curves in VTS testing as a result of the Google Requirements Freezing Program (GRF).

As default A/B support becomes a requirement on Android 13 launch devices with GMS, seamless updates should finally become available on devices from all OEMs. For more information about virtual A/B and how to speed up software updates, check out esper Blog linked below.
