[BETA] Virtual Device Testing for Android, predefined devices

Hello there,
We are using [BETA] Virtual Device Testing for Android step for running our UI tests, the problem is that we need to move through webView in order to login to our app, Because devices in test lab are each time started in a clean state, we need to omit the google welcome screen. We are using UIAutomator to omit that issue, but it’s not a very stable solution, sometimes works, and sometimes it doesn’t, especially on different devices.
Is there maybe a way or some hidden option to disable the “Welcome to Chrome” screen on start?
And is there a way to run tests on physical devices, not virtual?
