Problems on SG Core Plus (SM-G350)

Issue #38 resolved
Former user created an issue

Hello, I'm trying to activate properly the application on SM-G350, but it doesn't work. When I use "voice call" the call is recorded but even i can't hear anything and my vioce is not transmitted (but is recoreded). With other settings ACR informs the calls can't be recorded and recordings are empty (0 s.). Is it possible to achieve proper operating or my smartphone doesn't services it? I will be grateful for the information.
