Sorry, unfortunately I did get my numbers wrong. Based on a chart of Android versions taken from the Google site, it will probably be at least a month or two before 0.7% of Androids are running the latest version. My bad!

I keep a running copy of the stats here: https://oasis.sandstorm.io/shared/UtPbpOAW2OaV4QpkgwIclqGeGC...

Did you mean he was exaggerating? Because it's actually 0.6%.
