Does it squeal with the phone plugged in and charging?
My 'brick' that came with my Samsung Tab 7.7 squeals when plugged in with no device on the charger. However once you plug in a tablet or phone, it goes quiet. Wife can't hear it, and thinks I'm nuts. But it will keep me from sleeping at 5' from my bed.
It only squeals when my phone is plugged into it.
