Just a heads up for anyone really. And I’ve no idea if this is relates to Ionic 2 anyway. But today I rolled out an Ionic 2 app to a bunch of users and although it worked fine on my Nexus 5 on two android devices the users could not type into my password field on my login screen.
I quickly added Crosswalk to the project and re-built the app. All is fine now for both users.
So I recommend using Crosswalk!
