Italian publication WebTrek.it scored this picture of what it claims to be a Galaxy Note III, with all its panels stripped off, but not as stripped down as these slightly older pictures.
One can make out the S-pen bay, Qi contact points, the speculated 3,100 mAh battery in place, the micro-SIM slot, which you don't need to remove the battery to access, NFC antenna, and a micro-SD slot. A couple of things are taped out, one of them could be the camera lens. The LED flash peeks out.
Samsung is expected to launch the Galaxy Note III at the company's Unpacked 2013: Episode 2 event in Berlin, along the sidelines of IFA.
