Now that those of us brave enough to install the Android P beta have had a week or two to kick the tires, I wanted to revisit them again. Chaim Gartenberg has rightly pointed out that the combination of swipes and buttons means that the core navigation is a set of mixed metaphors. Others have called them “bad” and “a hot mess.” A gentler way to characterize the new system would be “polarizing,” but for Android users a better way might be to call it “rejection.”

Having spent some more time with the Android P beta, I tend to agree — but for different reasons. I am not at all put out by the mixed metaphors in the UI; some button taps and some swipes. Nor am I really annoyed that the gesture system hasn’t reclaimed any screen real estate, if I’m perfectly honest.
