Right, but that implies you can construct an entire chain that doesn't include checking their phone. Just pointing out, per the post i was replying to, it's not simply use the phone, get other evidence, don't worry about the phone's evidence being thrown out.
No, that's not the case here. You don't need a parallel construction in this example, because the UFED extraction (even if tainted by a similar exploit) wasn't illegally obtained.
