iPhone X, phone calls and Apple's Folio Case

I have an iPhone X with Apple's Folio Case, Great, right?

But ... when I made (or received) 'phone calls, people couldn't hear me properly - I was 'muffled'.

I tried voice memos. It worked.

I tried calling my own land line (with answering machine). Horrible, muffled.

The problem? I was folding the 'flip lid' all the way back so it was against the back of the 'phone. It seems the rear mic is relied upon and doesn't like being covered up. That's a concern for me as I reaaly wanted to have a firm grip on my 'phone. The only way it's going to work right now is to have the flap against my face. That's not the main concern (get a _good_ grip on an expensive device!).

The folded flap works just fine with "Voice Memos".

This is a SW issue. Yes, I disabled Accessibly "Noise Reduction" to see if it works.

This transcends the origami iPad case, where the inside rests on (e.g.) a mucky table. Then, it folds back up against the iPad's glass.

Well done. Could someone please look @ this?
