The company has confirmed to Android Authority that the GW1 sensor size comes in at 1/1.72-inch. This is slightly bigger than the 1/2-inch sensor size of 48MP cameras, likely due to the GW1 needing space for its extra pixels. So you should expect the 64MP camera sensor to offer a similar level of quality in low light as 48MP cameras in theory. But Samsung is also touting the sensor’s HDR prowess.
