I think the problem in the ROM
With AOSP ROM transfers contacts is good, but there is a problem with the voice with all ROM (AOSP, AICP, MIUI) (http://en.miui.com/thread-481961-1-1.html
Unfortunately I can not find a programmer who can help me to solve the problem with the voice.
Xiaomi support promises to examine the problem of 3 weeks
You have no way to help me find a programmer with which we could work together to solve the problem?
Today, I will experiment with AOSP and your application.
UPD. And one more question: you say "Handsfree" profile - there is HSP or HFP?
