I updated yesterday, thankful that the back button swap was now working (note that I have skipped the last two updates because of this so the problems I’m seeing might not have been in this release, specifically).
Unfortunately, now Android Auto is extremely laggy to the point that it eventually disconnects from my car.
As well, the adaptive brightness has become essentially useless. When I’m in the dark, it dims so much that I can’t really see the screen very well, and when I try to increase the brightness, it eventually just goes back to the way it was. The trigger to turn off the adaptive brightness is also buried in the settings, so temporarily disabling it is more of a problem than it used to be.
