What in the world provoked Android to forcefeed a feature that auto-predicts a reply and make it pop up as a notification quick reply? Example: do you want to hang out later? someone sends me. Android offers: "Sure" and "I don't think so". I'm much more likely to hit the wrong thing by accident - when I never use either of these "shortcuts." My google-foo is awful: I spent time looking for ways to turn it off for Signal but all the search results don't seem to apply to my version of Android and Signal (all the latest, and a Pixel). I had trouble even figuring out what's that called (eventually I discovered it's called Smart Reply). And typing is awful. It seems easier to type on the iPhone. And the battery life in ALL my pixels is always almost exactly 12 months before massive denigration, without fail. I leave it plugged in overnight every day, so that could be why. Someone please give me an excuse to move to an iPhony.
