Very curious what the reasoning is here.
Either cellebrite has got 100x better and faster and can wirelessly pwn a phone with NFC and BT and wifi disabled in a second or two using an antenna disguise...
@nprofile1q... I don't know about precheck or the US more broadly, but I've had my stuff explosives-swabbed numerous times by airport security in a few countries. It just seems to be a random thing, and I guess it makes sense to swab your phone because it's something most people touch after just about any activity, so there's a high chance they'll find traces of substances you've been handling.
