Android: Google Gemini and Circle to Search

On most modern Android phones, the built-in AI is Google Gemini. It acts as your assistant, and it also powers smart features across the phone, like searching whatever is on your screen and editing photos. This lesson walks through the everyday ones.

As of mid-2026, Google is moving Android phones from the older Google Assistant to Gemini as the default assistant. If you bought your phone recently, Gemini is likely already there. On an older phone, you may get a prompt to upgrade. Features vary by device and region, so check your Settings.

What You'll Learn

• How to use Gemini as your voice and text assistant
• How Circle to Search lets you search anything on screen
• How to hold a spoken conversation with Gemini Live
• Where to find photo editing and screen help

Meet Gemini, Your Assistant

You reach Gemini the same way you used to reach the old assistant. Press and hold the side or home button, or say the wake phrase if you have it set up. You can also open the Gemini app.

Because Gemini is built on a modern AI model, it handles more than simple commands. You can ask it to draft a message, plan a trip in steps, explain a topic in plain words, or compare two options. You can type or speak, whichever suits the moment.

The basic Gemini assistant is free on supported Android phones. There are paid Google plans that add heavier features and higher limits, but you do not need them for anything in this course.

Circle to Search: Search Whatever You See

Circle to Search is one of the most useful phone AI features there is, and it is easy to miss.

Press and hold the home button or navigation bar, then circle, highlight, or tap anything on your screen. You do not have to leave the app you are in. Try it on:

• A word you do not know, to get a quick definition
• An outfit or product in a photo, to find similar ones
• A paragraph in another language, to translate it in place
• A math or homework question, to see how it is solved

Because you never leave your current app, it feels less like searching and more like asking about the thing in front of you.

Gemini Live: Talk, Do Not Type

Gemini Live is a spoken, back-and-forth conversation. You talk, it talks back, and you can interrupt or change direction naturally, the way you would with a person.

It is great for hands-free moments. Practice for an interview, think out loud about a decision, ask follow-up questions while you cook, or work through a plan step by step. On some phones you can also share your camera or screen during the conversation and ask about what it sees.

Photo Editing and Screen Help

Google Photos includes AI editing tools. Magic Editor lets you move or remove objects, fix a busy background, and adjust a photo beyond simple filters. Open a photo, tap Edit, and look for the AI tools. Availability depends on your phone and your Google Photos app.

Gemini can also help with what is on your screen. Bring it up while looking at a page, an email, or a document, and ask it to summarize the page or explain a confusing part. This turns your assistant into a reading helper for anything you are looking at.

A Note on Image Generation

Android phones can also create images from a text description through Google's image tools. Like on other platforms, image generation uses cloud models, so heavier use may run into limits or paid tiers. For this course, treat it as a fun extra, not a core skill.
