Finding accelerometer location inside a phone

[Haversin]

you can find teardowns with photos on http://ifixit.com, which often even identifiy some of the chips on the main board.

Thanks Sebastian, great idea ! if I can get photos of the front and rear sides of the motherboard for my phone (Galaxy J7 Crown) then I can transform the accelerometer position estimate from the experiment into image coordinates and see if there is a chip there.
