@eug,
Regarding the cover fit. The FLIR instructions state that the camera will not fit in the cover when a spacer is used. I have already provided feedback to FLIR and stated that the cover is not that ergonomic and needs some more thought.
Oh, I didn't get any instructions with my Android model, except for a sheet of paper that gives a URL (
http://flir.com/onestart/).
The full user guide PDF in that link doesn't mention the spacer or cover. It does look like they were in a bit of a rush - one line in the manual says "Optimizing the image is described in more detail in section XYZ." There's no XYZ of course - it's on page 9, which mentions a coffee cup "below" where there's just blank white space.
There's also a sticker on the inside of mine that refers to "Made for iPod" even though it's an Android model. But hey, I'd rather receive it early than wait till they have the right boxes and finish the manual.

I hope the Lock Span feature comes to the Android app soon!
