Radiograph of my Galaxy S7. 80 kVp, 2.8 mAs, Canon Aero DR detector.
The large rectangular gray block is the battery. Superimposed on the battery, the NFC and wireless charging coils are easily seen. Volume buttons are on the upper left side, and the power button is on the right side. The rear camera is the square object in the upper middle. The selfie camera is the white donut shaped object just above and to the right of the rear camera. There’s the micro-USB port at the bottom middle, and the headphone jack to the left of the USB port.
