Update mechanism on Android

There are two types of Update mechanisms on Android

  1. Non-A/B OTA Updates
  2. A/B OTA Updates

Non-A/B OTA Updates:

Non-A/B OTA Updates are applicable for order android phones having a dedicated recovery partition. This dedicated portion contains the essential files and software needed to unpack the downloaded update package and apply the update to the partition.

A/B OTA Updates(Seemless):

A/B OTA Updates are usually ideal for modern android devices as they have two copy of each partition(A and B). This makes it easy to download the updates to unused partition while the device is idle.

A/B devices do not need space to download the update package because they can apply the update as they read it from the network; this is known as streaming A/B.

Final Words:

Android released OEM updates to their android phone frequently. Usually, these updates can be classifieds into two categories. First is security patch update where android attempts to fix the bugs, security issues, patches etc. These updates are usually small in size easy to install.

While on the other hand the second Android OTA update is released to update the software version, GUI updates, features updates and many more. This Android version update is not very frequent, the security updates happen every month.

Sadly, The Android OTA updates are not available to everyone at once. In other words, Android is pretty slow with releasing OTA updates for all devices at once. A pixel owner may get the OTA updates earlier as compared to Samsung and other android brands.

A Manual OTA update is nothing but just a process to update the Android device before the actual OTA update is released for your device officially. If you do not want to wait to install the update, you can always sideload OTA Update Zip file on your Android device to instantly update your device.
