01 December 2021 0

Google has released Android 12 TV final version aimed at developers. It is the newest Android TV operating system build meant for smart TVs. It has been over a month since Android 12 became available for Pixel devices. A few other phones have also received it and Google is also planning to release Android 12L for big screen devices.

Talking about Android 12 TV, it has reached its final version stage as per the beta testing schedule but is yet to become available for general users. It means you cannot install it on your Android TV device or a Chromecast yet. It can only be installed on the ADT-3, a developer device by Google. It is a device meant to help developers prepare and optimize their Android TV apps for the new operating system version.

The biggest difference in the new Android 12 TV build is full support for 4K UI rendering. It also includes a bunch of privacy issues with alerts for microphone camera usage.
