Gmail's Smart Compose has been widely available on the desktop for a while, but it's been quite limited in the mobile world. Unless you happen to have a Pixel 3, you've been out of luck if you've wanted Gmail to help write your messages. Thankfully, Google is casting its net much wider. Android Police has discovered that Smart Compose is rolling out to other devices, including third-party phones like the Galaxy S9+ and OnePlus 6T. Engadget can attest to the expanding hardware support, as you can see on the Essential Phone above.
