NVIDIA SHIELD is the first Android TV box to get Google Assistant, and you can already do cool things with it, like use it when your TV is off. If you need a visual notification that he heard you, then there is a hidden setting for this too.
There are actually a couple of toggles in the Developer Options menu that make the controller, or the SHIELD itself, flash when it detects the words «OK Google», making it a lot easier to use when you’re away from the TV… provided that You Of course, there is a controller nearby.
However, before you can enable said setting, you first need to enable developer options on your SHIELD. The process is the same as on Android phones and tablets, but it’s quick and dirty here: go to settings, then scroll down to About. In this menu, find the entry «Build», then click on it seven times. Toast notifications will let you know how many more clicks you need, and on the final notification you will know that «you are a developer». Ready.
After that, go back one menu and scroll down to the newly added Developer Options entry. Open it.
There’s a lot going on in this menu — a lot of things you probably don’t need to worry about right now — so scroll to the very bottom. Here you will find two options: «Blink controller LED on hotword detection» and «Blink SHIELD LED on first pass hotword detection».
