Comment 5 for bug 1607427

more details and how to trigger from this bug report https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1637992

arale/rc proposed

open a random app, long press the home button to reveal the launcher, let it go. now short tap/press on the home button to go to the home scope. doesn't work.

also, i think it would be better to replace the behavior of the home button, instead of revealing the launcher(makes no sense on a phone) to trigger the app switcher
