Does anyone know if this border security inspection is a goon scrolling through your photos, or do they just copy the whole memory of your phone to a real “threat detector”.

When I used to work in cell phones and I was debugging them, when they crash I would analyze the OS core dump for things like repeated phone numbers or emails etc. Basically any thing that signifies a memory leak. But that core dump would be the entire phone’s RAM and storage.

Border guards have always been of questionable value: they inspect your TN-1 and made somewhat arbitrary decisions on your documentation. You’d go one week and they’d send you to secondary but another they’d glance at the docs and just wave you through.
