>> disable the feature before going through customs
I keep seeing people mention locking the phone before going through customs. This accomplishes nothing. If they ask for your device, you are required to unlock it. If you refuse to unlock, best case scenario means you turn around and go home. Worst case scenario, you are detained as a criminal. If your plan is to fight back and not allow the agents access to your phone, you won't be making it across the border. Bringing the device with you means you must be willing to unlock without causing a fuss. The only way to "win" is to not bring the device.
This is not true when entering the US as a citizen. They cannot compel me to unlock the phone with a password and they cannot hold me for more than a short period over it. The worst they can do is confiscate the phone.
