I thought I would take a look inside a power supply that I suspected was a counterfeit. See just what is going on with it. This Samsung power supply was making strange things happen with my phone while it was plugged in. Yes, it charged the phone fine, but it made the touch screen go all screwy, and I suspected it was a rather noisy switcher in it. I had bought it from eBay for next to nothing, so I am expecting it to be somewhat nasty inside.
Guess what? I was right.
