Physical placement of specific sensors in Google Nexus 7 (2012) I am working on a project that requires me to know where specific sensors are physically located inside the device. I can estimate the location of NFC and light sensor (of course) but what about other sensors like magnetometer, g-sensor? If any of you know about the placement of specific sensors (doesn't have to be very precise) that would help me.
Here is a labelled photo of the nfc antenna behind the cover. It runs the perimeter of the black cover on the phone back
