At least with iOS, you can do a factory reset before you leave, and restore it after passing through customs, and for legit reasons - you're paranoid about having your device taken from you while travelling, and you don't want thieves to be able to access your contacts, pictures, whatever. You don't have to specify that you consider customs agents thieves, that's just up to you if you wanna put that lil' spin on it. (But for real, this seems to me to be a bulletproof way to both make sure TSA can't access data on your device AND make sure you get pulled aside "randomly" for an extra-long questioning session.)
