Liking the new back gestures. I was already using an app called Full screen gestures that have me a swipe back gesture. Android gestures are now a lot like iOS now. Also, dark mode in Android Q is nice, but not all Google's own apps have dark mode yet.
With Android Q, the back button is being retired in favor of a new side-swipe gesture that will let you go back by swiping in from either edge of the phone.
