are there two mics mounted, in order to record HD videos in stereo?
No stereo audio recording in S8 although there are two mics. Only one mic is used. When in interview mode, two mics may be used for interviewer and interviewee separately.
What is a "hear rate sensor" referenced in your text? Where is it and how do I use it?
Sorry, it's heart rate monitor. We will correct the page later.
You can use S Health app to check the heart rate. You can also use it to take selfies.
Please let us know features of mini hole at top right corner at aluminium frame just by the side of which bar mark....
you probably refer to the secondary mic. You need two mics to do noise cancelling (when making calls). Besides, when you use the voice recorder, it can choose the proper mic for you and the interviewee. It is better illustrated in this page.
Is it safe to put a 1 inch diameter disc of a radiation deflector over the GPS antena and the battery area on the outside of the 'otterbox' type case on a
Samsung galaxy s8?
Not sure. We never tried that. Why do you want to try this?
Is there a schematic showing the top right Mic connections. One of the comps got knocked off, and lost, during a repair. I think it was a cap to the top mic, but I can't find the actual component. I have tested this and the top mic is the only thing not working. The mic chip is marked S1811, and it has only a few comps associated with it. Should be an easy fix, if I could get the proper value comp. Lacking that, I'll just have to try a few caps to see what works. The comp was brown, with solder bands around component on both ends. assume cap of some unknown value.
Any idea what the comp might be? It's the comp that should be on the pads shown in this photo:

Thanks
Not sure. You can visit local Samsung service center to get the part number. If you have the chance to talk to the engineer, then you can get detailed info. But if you have to go through the registration counter, you can check with the duty manager to see whether you call talk to repair engineer directly.
S8 Active where and what is largest size metal plate for the magnetic mount with the least interference with the phones functions?
Normally, the magntic mount comes with metal discs which you need to stick to the back of the phone.
there is a key that came with the samsung galaxy s8 in the box. what is the key used for?
A key? Is the SIM card ejection pin?
You may share a photo of it in our Facebook page.
Is there a way, to only replace / repair the Gps antenna? Or do I have to replace a larger unit to accomplish?
Can't really find something about gps hardware repair
It is not worthy. Normally it is not just an antenna issue.
