TeaGoogle says Gemini will replace Google Assistant on Android phones in 2025, except on phones with Android 9 or earlier and that don't have at least 2GB of RAM.
GethI find Gemini has better communication and comprehension ability compared with assistant, but can do even less when it comes to controlling the phone. No reminders, no calendar events, no messages, no integration with anything. Just talking.
I would have preferred assistant talk and understand better, instead of a completly gimped alternative that does that and nothing more.
Mine does reminders and events now. It can also do Google home stuff.
