Galaxy S5 Neo with this Rom here.
Settings are the same, in Standard API everything standard.
I get crash on Voice up + voice down.
I get a recording (ok sound quality) with voice communication.
But this also doesnt work with wireless headphones. While the phone call itself works with wireless.
My phone partner can hear me, but call recorder doesnt record MY microphone.
On settings Voice recognition and Default, my voice gets recorded but not the other side.
So both phones have the same problems.
Up+down link doesnt work, on one it has sound problems, on the other it crashes.
Voice Communication work on the phone, but not with any wireless headphones.
