What is Google Gemini and why use it

Google Gemini is Google’s AI model that has replaced Google Assistant on Android devices. Unlike the old assistant, Gemini can hold more natural conversations, understand context, analyze images, and even help with complex tasks like writing text or summarizing emails.

The main difference is that Gemini is based on a large language model (like ChatGPT), while the previous Assistant worked more like a set of predefined commands. Gemini understands what you say better and can do much more sophisticated things.

What Gemini can do

• Answer complex questions with context
• Write and summarize text
• Analyze what’s on your screen
• Control smart home devices
• Manage your calendar and reminders
• Perform advanced web searches
• Generate images (with Imagen 3)

Pro-tip: Gemini can read what’s on your screen and answer questions about it. If you’re reading an article and don’t understand something, just say “Hey Google, explain this” and Gemini will analyze the screen.

Before you start, make sure you meet these requirements:

Gemini vs Google Assistant: what changes?

If you’ve been using Google Assistant for years, you’ll notice important differences:

Overall, Gemini is smarter but slightly slower on simple tasks. For things like “set an alarm” or “turn on the lights,” Assistant was instant. Gemini takes a bit longer but understands complex requests better.

• Try restarting your phone after updating.

FAQ: Frequently asked questions

Is Gemini free on Android?

Yes, Gemini is completely free as an assistant on Android. There is a paid plan (Gemini Advanced) that gives access to the most powerful model, but the basic assistant costs nothing.

Does Gemini work without an internet connection?

No. It needs an internet connection to work, as processing happens on Google’s servers. Without data or Wi-Fi, it won’t respond.

Can I use Gemini and Google Assistant at the same time?

No, you can only have one as your primary assistant. You can switch between them in settings, but they don’t work simultaneously.

Does Gemini use more battery than Google Assistant?

Battery usage is similar. When using the voice assistant, the impact on battery is minimal for both. If you use Gemini with the screen on for long conversations, usage will be higher due to the screen, not the AI.

Conclusion

Activating Google Gemini on Android is one of the best ways to take advantage of artificial intelligence on your phone. In under five minutes you can have a much more capable assistant than before, with writing, analysis, and image generation features. Try it for a few days and you’ll see the difference. And if it’s not for you, going back to Google Assistant is just as easy.
