> it does seem prudent to wipe your device and restore when you land. Then again, border officials can also deny you entry with very little justification so who knows?

For example, if they instruct you to turn on the device, and they see the setup screen or even just that it has no photos, no messages, nothing, might raise suspicion I would imagine.

Good luck trying to argue with them that absence of data should be considered normal and not a reason for them to harass you :(
