My opinion is this is a very welcome move. But I don't expect OEMs to greatly improve their device's support liftime: the industry is still not incentivized towards supporting a device for 4 years. On that point, please note how the SoC mentioned is amongst the highest-end. Don't expect low-end devices to follow suit. As a side-effect: - It's likely the number of new features on a older SoC will drop (for instance I think we wouldn't have WPA3 on SDM 855 under such a scheme) - Open-source community support will become harder. At the moment, a flagship released with Android 8 will get Android 10 drivers. With this, a flagship released with Android 11 will remain on Android 11 drivers forever. Community support is easier with the most recent drivers, so we'll loose that.
