Pretty cool for detecting wireless devices. If you're finding your ambient readings higher than 60 (I've got a lot of devices lol) try airplane mode for a few minutes while you do the calibration wiggle, this fixed one phone I had get stuck at 160+. You'll get the strongest readings from one spot in your phone and you can figure it out by basically rubbing a known device all over your phone until you get a massive spike. I rubbed 2 phones together, only detected each other's cameras and mics.
