Android Auto works well! I've used Finamp, Antennapod, CoMaps, and Google Maps with it and they all work great. I can voice search destinations with Google Maps while driving and it works. The only downside of Android Auto is that you have to install some Google apps for it to work, which feels icky on an otherwise-de-Googled device. No connection issues.

Battery life is great! I did an experiment when I first got it to see how long I could go without charging and got 3 full days (with plenty of use, since I was excited to play with my new phone). I'm ending most days around 50% now that I've got a bunch of stuff always running in the background (KDE Connect, Tailscale, etc.).

The mic and speaker aren't amazing, but I haven't had anyone say they've had trouble hearing me. I haven't encountered anything I would describe as a bug, though I'd say that my previous phone (an iPhone 15 Pro Max) had noticeably better speakers.

And I actually don't know about the haptics, since I leave my ringer on pretty much all the time. I've definitely had times when I've been in a concert or movie with it silenced and felt notifications, but I have no idea if I'd be able to detect them if I were walking around or something. I've always been a ringer-on guy unless I'm wearing a smartwatch.
