Check Whether Your Device Supports Seamless Updates and Project Treble

Every Android user out there knows about the hassle of upgrading the system firmware on their devices. Prior to the debut of Android Nougat 7.0, all of the system firmware files were downloaded onto the storage of the device. Once the update was downloaded, the user had to restart his/her device and wait for 15-20 minutes for the updates to be applied and installed. However, after installation, the user had to wait another 5-10 minutes for the updates to be finalized as their devices would show “Android is upgrading” dialogue. This was a waste of precious time for users. Due to this fact, many users simply kept postponing the updates on their devices.

To combat this issue, Google introduced a feature called Seamless Updates in Android 7.0 Nougat. This feature employed a new A/B partition system. Phones which support this type of partition system have two sets of partition namely a_slot and b_slot. The downloaded updates all go to the inactive slot, hence the name Seamless updates. The phone would eventually switch to the inactive slot when the user decides to install the update upon reboot thereby drastically reducing time to install and configure the updates. Speaking of which, the ”Android is upgrading” dialogue has no place here and the device boots as usual. However, user data is shared mutually between the partitions. Devices such as the first and second generation Google Pixels, Xiaomi Mi A1 and Moto Z2 force and the Essential Phone are equipped with this type of partition system.

Advantages and Disadvantages of A/B partition system

Alright now lets come to the advantages and disadvantages of this type of partition. There are two advantages. firstly, in case the updates did not install properly, then the device would switch to another slot. For Example, if the updates are being installed in the background in the b_slot, then, the device can simply switch to a_slot seamlessly. The second advantage is that as I mentioned earlier, the user no longer has to wait for the “Android is Upgrading” dialogue, the device will boot as usual.

As far as disadvantages are concerned, this type of partition would eat up the storage space on a device because of two sets of partition and also no matter how a large amount of storage space a device is equipped with, this system is still a problem that exists.
