Very cool! I looked into it a little bit, a good option depending on your threat model is to simply leave it in a faraday container (read: aluminum foil envelope - or the more sophisticated stuff) when you don't want it to be visible. But then, you kind of have to let go of having that phone usable at home at all, and end up having a "dirty" and a "clean" phone. Then again, just useful depending on your threat model.
