The first problem is that it's just slow. If I want it to turn off some light, it takes a long time before responding.
But yeah, the failure to do basic tasks. I have a routine that I used to have it run (controls several devices at once). Now:
10-20% of the time it runs it.
60% of the time it says it's running it but it doesn't do anything.
20-30% of the time it says it can't do it unless I opt in to invasive permissions. And when I opted into them, it still failed about a third of the time. So I opted out again.
Man, I hate touch screens. And I hate Android Auto. My previous car had an aftermarket Bluetooth system (radio, etc). It was way, way better than Android Auto or any entertainment system I've seen in any car.
But timers and smart home actions are definitely less reliable and sometimes take absurdly long to respond (like 20-30 seconds p99).
To give you an example, I was having coffee the other morning while unloading the dishwasher and asked the speaker if today was a good day to apply weed and feed on my lawn. This was not possible with the old assistant and was useful to me.
And now if I want to use Gemini on my phone I have to replace Assistant. Nah, I'll keep Assistant thanks, and just have a shortcut to load the Gemini in the browser.
Except the browser experience is so fucking buggy, constant reloads needed..
I have never had trouble setting timers with either.
