Only true for bad informasjon gathering operations. They have device id and ip address, so they know it is an old phone. They will know that your new phone is your new phone and will prioritise that one. Now they just also know that you are trying to cheat the system, so you are now put in the “watch with more care”, so you will be the most advanced agents on you.
Those are accidents vs the op which was not an accident. It was legit the right place and searching for the right thing. They had some evidence to do the search legally. So your comment and this hypothetical aren’t quite the same.
