Dear international Android Police readers: thank you. Our staff is relatively small, so we can only be on the ground (so to speak) in a handful of countries... most of which are the US. So when a bunch of you from one particular place start telling us that something big is happening, we listen. The latest one is Google Now On Tap, the contextual screen-based search tool, which appears to be rolling out in Brazil right now. If you're in the country (and happen to be running Android M), give it a shot.
Update: Turns out Google Now on Tap is now enabled for the Portuguese locale rather than specific countries. So while Brazilians and Portuguese will be the most likely users to notice, the country doesn't really matter - the locale does.
Remember, to activate Now On Tap from Android 6.0+, hold down the home button and wait for the "frame" animation around the screen to complete.
New users, check out the succinct little Google ad if you're not sure what Now On Tap is or how it will benefit you. And if you find the whole thing to be unnecessary (as approximately a third of Marshmallow-using Android Police readers do), it's easy to turn it off in the Google app's Settings menu.
- Hell (and everyone else who sent this in)
