Google Assistant Explained: Commands, Settings, and the Move to Gemini

Quick answer: Google Assistant is Google’s voice-activated helper that has been used on Android phones, tablets, smart speakers, and other devices. It can handle tasks such as making calls, sending texts, setting alarms, checking the weather, controlling compatible smart home devices, and answering questions with voice commands. Google is now transitioning the mobile Assistant experience to Gemini, so Android users may see Gemini instead of classic Google Assistant as the change rolls out.

If you’ve noticed your phone responding differently than it used to, you’re not imagining it. Google Assistant has been the familiar voice behind Android devices for years, helping with everything from morning alarms to hands-free directions. But Google’s assistant experience is changing, with Gemini becoming the newer AI-powered assistant on mobile devices.

This guide explains what Google Assistant is, what it can do, useful voice commands, important settings, privacy options, common problems, and what the move from Google Assistant to Gemini means for Android users.

What Is Google Assistant and How Does It Work?

Google Assistant is a voice-activated digital assistant developed by Google. It was designed to understand spoken requests and help users complete everyday tasks without having to type or navigate through multiple menus.

Depending on the device and available features, Google Assistant could respond to a wake phrase such as Hey Google or a touch or button shortcut. It could then use speech recognition and natural language processing to understand what you were asking and provide an answer or perform a supported action.

Google Assistant could connect with your Google account, phone apps, contacts, calendar, and compatible smart home devices. This allowed users to perform tasks such as sending messages, checking appointments, getting directions, or controlling connected lights with voice commands.

The exact capabilities could vary depending on:

• Your Android version
• Your device manufacturer
• Your region and language
• The apps installed on your device
• Your Google account
• Which Google assistant experience is available on your device

What Can Google Assistant Do?

Google Assistant was designed to make everyday tasks faster and more convenient. Common uses included:

• Making phone calls
• Sending and reading text messages
• Setting alarms and timers
• Creating reminders
• Checking the weather
• Answering general questions
• Searching for information
• Getting directions and navigation help
• Playing music and other media
• Opening supported apps
• Controlling compatible smart home devices
• Managing certain phone settings and tasks

Not every feature worked on every device, and some capabilities depended on the apps and services connected to Google Assistant.

Google Assistant Voice Commands You Can Try

Voice commands were one of the main reasons people used Google Assistant. Here are examples of common commands that illustrate what the assistant could do.

Calls and Contacts

• Hey Google, call Mom.
• Hey Google, call the last number I dialed.
• Hey Google, call the nearest pharmacy.

Text Messages

• Hey Google, send a text to Sarah.
• Hey Google, read my latest message.

Alarms and Timers

• Hey Google, set an alarm for 7 AM.
• Hey Google, set a timer for 10 minutes.

Reminders and Calendar

• Hey Google, remind me to call the dentist tomorrow at noon.
• Hey Google, what’s on my calendar today?

Weather

• Hey Google, what’s the weather today?
• Hey Google, will it rain this weekend?

Search and General Questions

• Hey Google, how tall is the Eiffel Tower?
• Hey Google, what’s the capital of Japan?

Navigation and Directions

• Hey Google, navigate to the nearest gas station.
• Hey Google, how long will it take to get home?

Music and Media

• Hey Google, play my favorite playlist.
• Hey Google, pause the music.

Smart Home

• Hey Google, turn off the living room lights.
• Hey Google, set the thermostat to 70 degrees.

These commands are useful examples of the type of hands-free tasks Google’s assistant experience has supported. On current Android devices, some of these requests may now be handled by Gemini instead of classic Google Assistant.

How to Use Google Assistant on Android

The way Google’s assistant works on Android has changed over time. Android phones also use different interfaces depending on the manufacturer and software version.

Historically, users could access Google Assistant through voice activation, a home or power-button shortcut, or a screen gesture. Today, many Android users are being transitioned from classic Google Assistant to Gemini, so the assistant that opens on your phone may be different from what you used previously.

If you want to find out which assistant is currently active on your phone, check your device’s default digital assistant settings or open the Gemini app if it is installed.

How to Activate the Google Assistant Experience

On supported devices, Google’s assistant experience can be activated using voice or touch. Depending on your device, available methods may include:

• Saying  Hey Google when voice activation is enabled
• Pressing and holding a configured power or side button
• Using a supported screen gesture
• Opening the Gemini app directly

On current Android devices, these activation methods may open Gemini because Google is transitioning the mobile Assistant experience to Gemini.

Google Assistant Settings You Should Know

Google Assistant settings have allowed users to customize how the assistant responds and interacts with their device. Depending on your device and current Google assistant experience, available settings may include:

• Voice and language preferences
• Voice activation
• Voice Match
• Personal results
• Assistant notifications
• Connected apps and services
• Privacy and activity controls

Settings and menu names can change as Google updates its assistant products, so your phone may not show exactly the same options described in older guides.

Voice, Language, and Personalization

Google’s assistant experience can support different languages and personalization options depending on your device and account. Users may be able to change language preferences, configure voice-related options, and control whether personal information such as calendar or contact data can be used for certain features.

Google Assistant Privacy and Activity Controls

Privacy is an important consideration when using any voice assistant. Google provides account and device settings that can help users manage how assistant-related information is handled.

• Microphone permissions: Review which apps have microphone access on your Android device.
• Google Account activity: Review available activity controls associated with your Google account.
• Voice and audio activity: Depending on your settings and Google’s current options, you may be able to review or manage voice-related activity.
• Personal information: Review which connected services can access information such as contacts or calendar data.
• Activity deletion: Use the privacy controls available in your Google Account to review or delete supported activity.

Google’s privacy controls can change over time, so it is a good idea to check the current settings in your Google Account rather than relying only on an older guide.

Why Is Google Moving From Assistant to Gemini?

Google is transitioning the mobile Assistant experience from classic Google Assistant to Gemini, its newer AI-powered assistant. Google began removing access to Google Assistant on mobile devices starting September 3, 2026, and the rollout may take several weeks to reach everyone.

This change affects the assistant experience on mobile devices and certain accessories paired with those devices. Depending on the device and rollout, users may see Gemini become their primary assistant instead of classic Google Assistant.

Gemini is designed around a more conversational and generative AI experience. Instead of focusing mainly on short, predefined tasks, Gemini can handle more natural conversations, help with writing, work with connected apps, and respond to more complex requests.

However, the transition does not mean that Google Assistant has disappeared from every Google device. Google says that Google Home and Nest smart speakers and displays are not affected by this particular mobile transition. Cars with Google built-in are also treated differently from Android Auto experiences projected from a mobile device.

What Happened to Google Assistant on Android?

Google Assistant is being phased out as the primary assistant experience on mobile Android devices. The transition began on September 3, 2026, and Google says the process may take a few weeks to reach everyone.

During the transition, some devices may still show classic Google Assistant while others may already use Gemini. Once the transition reaches a particular mobile device, Gemini becomes the newer assistant experience and classic Google Assistant may no longer be available there.

This is why two Android phones can appear to behave differently even when they are running similar versions of Android.

Google Assistant vs Google Gemini

In simple terms, classic Google Assistant was mainly built around executing everyday commands, while Gemini is designed as a broader conversational AI assistant. The two experiences overlap in areas such as calls, messages, reminders, and other tasks, but Gemini is designed to handle more open-ended conversations and generative requests.

Google’s current Gemini documentation also confirms that Gemini can use connected Android capabilities for tasks such as making phone calls and sending messages. 1

Google Assistant vs Google Search

Google Search is primarily designed to help you find information across the web, while Google’s assistant experience is designed to let you interact with your device and connected services using natural language and voice.

Google Assistant Not Working: Common Problems and Fixes

If Google’s assistant is not responding as expected, the cause may be a setting, permission, software update, or the transition to Gemini.

Google Assistant Not Responding

Check your internet connection and review microphone permissions for the Google or Gemini app. Also check whether your device has already transitioned to Gemini.

Hey Google Not Working

Check whether “Hey Google” and Voice Match are enabled for the assistant experience currently active on your device. If Gemini is your assistant, check the Gemini settings for hands-free activation.

Microphone Problems

Test the microphone with another app to make sure the hardware is working. Then check microphone permissions under your Android app settings.

Voice Recognition Issues

Try speaking in a quieter environment and check your language settings. If Voice Match is available, you can also review or retrain the voice model.

Assistant or Gemini Not Opening

Restart your phone and check for pending Google app, Gemini, or Android system updates. You can also check which app is selected as your default digital assistant.

Wrong Language Detected

Review the language settings for your current assistant. The exact menu can vary depending on your phone and the assistant experience you are using.

Activation Problems

Check your phone’s gesture, power-button, or side-button settings. Android manufacturers can use different controls for activating a digital assistant.

Features Disappearing After an Update

Google regularly changes and updates its assistant products. If a feature has disappeared, check whether your device has transitioned from classic Google Assistant to Gemini and review Google’s current support information.

Gemini Appearing Instead of Google Assistant

If Gemini appears when you try to use Google Assistant, this may be part of Google’s mobile transition rather than a problem with your phone. Google began removing classic Google Assistant from mobile devices on September 3, 2026, and the rollout may take several weeks.

Smart Home Commands Not Working

Check that your compatible smart home devices are properly connected to your Google Home setup and are online. Smart home availability can vary depending on the device, service, and current Google assistant experience.
