Android user here. Google Assistant with Gemini is almost close to useless. Before Google assistant had gemini i used to be able to do simple things like "remind me to do x in y minutes" or "turn lights off" or "remind me that the apt gate code is 1234"
Now most of that either is "i cant do that" or "sure, playing Ellie Gouldings Lights at 200%" (which admittedly was funny in hindsight, had it not woken my infant daughter up and caused a sleepless night)
