Question Mystery of external microphone

Hi everyone!

From few week I've been tried to change my Samsung Galaxy Ace to dictaphone with external micorphone. My search results was quite logical: I need TRRS cable, and it should work fine. So I bought one and tries a few different mics that I have, but in every case it didn't works... I tries a lot of apps that should give me good result (in theory) but nothing... Then I had an idea to try record a video when my external mic is plugged in. And... it works! But... I want record just audio in some app to wav or even mp3 to replace my crappy audio from camcorder in editing process... Does anyone could help me?

PS: I have the same problem with my Lenovo S6000 tablet.
