Current behavior:
I built with the latest 3.2 Ionic code, with Angular 4.1.0, cordova 7.0.0 on Ubuntu 16.04 with Android 25 SDK, when I switch app then switch back to my app on an Android 7.0 Galaxy Note 5 phone, the fab button just stops working.
It doesn’t show fab list after click fab button, no response at all.

Haven’t tested on iOS yet.
