I'm french and my english is so bad :
I want to know if anybody can do this with create mod xposed ???
I use my android phone in my car for calling with my jack 3.5 on my radio
but my interlocutor can head an echo for him but this is depand of my rom and for example, cyanogenmod my interlocutor didn't have echo and he didn't hear my music playing sametime etc...
it's aleatory with the rom has installed.
anybody know if it's possible to create a mod or other to fix it,
I think we can draw with appcall of cyanogen because with cyanogen rom the echo it's not present.
if anybody have an idea I listen,
