News on Mobile OS Releases, December 2020

Android

Android has been working on making OS updates easier and faster to deploy. For this reason, changes have been made to help their partners launch their devices on Android 11 or offer Android 11 OTAs on their devices earlier.

• backwards-compatibility guarantee: with each Android release, Project Treble publishes Generic System Images (GSIs), guaranteed to be backwards-compatible with the previous 3 versions of vendor implementations, in addition of course to the current release.
• new vendor-impacting requirements for Android devices are never retroactive. This principle is extend to the SoCs as well as to devices.
• Android is reusing the same OS framework software across multiple Qualcomm chipsets. This dramatically lowers the number of OS framework and vendor implementation combinations that Qualcomm has to support across their mobile platforms and results in lowered engineering, development, and deployment costs.
