As an Australian who wrote about the demonstrations while on campus, I gave my phone a superficial clean before flying to the U.S. I underestimated what I was up against.
You can run a direct disk copy of a phone and then recover “deleted” data. You need root access to do it. I’m sure they have plug in tools to do it on most phones. Just don’t give them your access password or don’t use your old phone.
Just say that you brought an old phone in case it gets lost or stolen since you don’t have cell access anyway, no point in bringing your good phone.
