[Solved] Huawei P8 Lite: MMI Function Test - How to Run? Test Conversation Microphone, Code Needed

Colleagues, what code to run the test of the MMI function. I want to test the conversation microphone in one of my P8Lite. Interlocutors complain that I am very weak. The smartphone in perfect condition, never fell, used by his wife and suddenly it is not known when the problem with the microphone began. Microphone net clean. I do not know if the problem is soft or the microphone itself. I am asking for a hint.
