If you have activated on the Samsung Galaxy S7 the RAW mode and then taken pictures in the expert mode, then you now might be wondering where to find these recordings. The Samsung Galaxy S7 takes in professional mode and activated RAW mode always two images when you press the shutter button.
Once in JPEG and once in RAW. The JPEG file is displayed in the Android Gallery, but the RAW file in the format "DNG" not. To view the RAW files, you need an appropriate app, or you can find the files in the following folder stored:
Open: Menu --> My Documents --> Internal memory or memory card
The RAW images are then stored here: / DCIM / camera
Now you know where on the Samsung Galaxy S7 the RAW files in DNG file format are saved.
