I carefully popped the front face-plate off which allowed me access to turn/adjust the actual lens and to focus it further-out, but I had to kind of guess because I have no access to the live video out yet. Then I did the microphone fix... which was relatively easy.... but re-assembling it was a bit "hit and miss"!
i.e. If I didn't get the "top button ribbon-plate" into it's slot properly... it would NOT turn-on! Aiii so be careful. I will have to add some mic foam to the mic next to quiet-down the excess noise being picked-up to complete the mod.
The Yi cam was hard-mounted on the Quad this time and picked-up some jello.
