How to check if your Android Phone supports Seamless Updates

According to Google, latest mobile OS Android P is on its way to hit the public users while developers have already started testing to make sure the update is out of bugs and smoother user experience.

Recently, Android Nougat launched support for seamless updates with A/B partition system, wherein the new partition system there are two sets of partition which is used for seamless updates (a_slot and b_slot). The word “seamless updates” defines that all updates now gets downloaded to the inactive slot. When a user reboots to finish installing, the device seamlessly switches over to the inactive slot, thereby eliminating downtime. User data is shared between the partitions.

A/B partitions have their advantages and disadvantages both. The main favorable point here is that if an update isn’t introduced appropriately, the device can essentially change to the next slot(for instance, if the update is being installed in the background to the b_slot, at that point the device will change back to the a_slot) and boot blunders will be maintained a strategic distance from. The second favourable point is that users never again observe the “Android is overhauling… ” screen. At the point when the update has wrapped up, the device reboots normally.

Then again, the A/B segment framework has critical detriments. It expands the utilized storage space of a device in light of the fact that there are presently two sets of partitions. The capacity increment may not be major on devices having a lot of internal storage, however, it exists. The more significant issue here is that A/B allotments have ended up being an obstacle to improvement for a few devices, including the original Google Pixels, the Moto Z2 Force, and the Xiaomi Mi A1.
