With the latest update on Android TV software, Google Assistant has become possible. The same goes with Sony. Sony’s 4K HDR devices running Android OS will now get Google Assistant. This new feature will be available on all 2017 models & on few of the 2016 models too. From 2016 Sony TV will get Google Assistant on the following models.
If you are a Sony TV user & haven’t got Google Assistant update, then your device haven’t got the latest update. Once you get the latest update on your TV, you can then remotely control your smart TV via your voice commands.
