There's unlikely to be any real control put on this, so assuming that this is "a new normal" we need to work out how best to deal with it. I found a couple of articles which cover some precautions but aren't quite "paranoid enough" (warning: both of these articles showed me full-paged ads):<p><a href="https://www.computerworld.com/article/3209648/android/the-paranoid-android-travelers-data-protection-checklist.html" rel="nofollow">https://www.computerworld.com/article/3209648/android/the-pa...</a><p><a href="https://www.wired.com/2017/02/guide-getting-past-customs-digital-privacy-intact/" rel="nofollow">https://www.wired.com/2017/02/guide-getting-past-customs-dig...</a><p>We need a nice, clean, to-the-point github readme style list. Off the top of my head:<p>- Backup contents of device to two places, confirm both, delete it all from device<p>- Record all personal accounts on the phone, make sure the login/email/passwords are known, then remove them all<p>- Factory reset the device (if asked about why it's "blank", say that you bought it recently, specifically for the trip. Work out some reasonable excuse)<p>- Create a throwaway account, set that up as the only account on the phone<p>- Encrypt the device<p>- Don't use biometric unlocks<p>- Use a relatively simple passcode that isn't related to any of the ones you may regularly use (unless you already have a regularly used "burner" passcode)<p>- Remove your local / home sim card before going through customs (if asked, you're planning to buy one that's local to the country you're visiting)<p>- Any data that you may need to get back on to your phone once you're through customs should be made available somewhere online and accessible via credentials you can either remember or have stored elsewhere. Possibly through a chain of dependence such as remember the credentials to download the VPN config, then access further documents / details via the VPN.<p>I fundamentally treat phones and laptops as disposable devices so that, if they're lost or stolen there should be minimal life impact. If they're the only store of photos of your kids precious milestones, then you're doing it wrong (you're also probably not someone suspicious, but in that case you shouldn't be subjected to government departments stealing said photos).
