Last year, it was revealed that according to some changes to the Android 11 Vendor Test Suite, virtual A/B partition support would become a must for smartphones working on Android 11 and later. The seamless updates feature uses A/B partitions to install new firmware in the background while users are still using their devices. In the latest Android 11 Compatibility Definition Document, seamless updates have moved from the category of an important requirement to the category of a general recommendation. However, Google still encourages phone manufacturers, such as LG, Sony, OnePlus, and Motorola, to implement the seamless updates feature.
Although Android seamless updates were introduced back in 2016, Samsung smartphones still don't support the feature. And the flagship Galaxy S21 series is no exception. The question is, is this a big drawback? Since seamless updates use virtual A/B partitions, they take up a lot of storage space. Add to that Samsung's One UI software, which is also quite large. What else? The lack of a microSD card slot in the latest flagships. The conclusion is obvious as seamless updates would be implemented at the expense of internal storage.
