Does a Google Search not bring anything up at all @ballcrusher 

If you contact Samsung Support they maybe able to help however I'm not sure they'll be able to help further as the phone is only supposed to be worked on by an authorised Samsung engineer so they may not be able to advise.

There is a YouTube creator called jerryrigeverything who performs tear downs on Samsung phone's who you maybe abke to reach out to.
