Been using Samsung messages for years, not Google messages, but I just wanna comment.
I'm OK with it. It's been an ai race. It's natural that Google is taking advantage of the millions of Android phones and of the fact that many are using Google messages and Gmail. Adding Gemini to Google messages is sensible to me. I just hope it won't be annoying.
Gmail has been my main email but I didn't see Gemini in it. Maybe in the future?
Frequently unresponsive or very unstable apps shouldn't have been in the Play store in the 1st place.
Anyway, to the Play store's credit, I downloaded many bank apps and I never got a fake bank app.
