And Google doesn&#8217;t tell you that it&#8217;s on your device after it&#8217;s installed.<\/p>\n<p>Hanff said Gemini Nano will only be installed if the person&#8217;s device meets the hardware requirements. It&#8217;s unknown how many people have gotten the install.<\/p>\n<p>Gemini Nano performs tasks such as detecting scam phone calls, helping you write text messages, summarizing recordings and analyzing Pixel phone screenshots. It&#8217;s not to be confused with the AI Mode pill in the address bar.
