How to grant a permission to an app? I have an LG G4 with Android 6.0. I installed an application for learning English. The app requires me to watch a video and then to speak. However, I'm having trouble with the latter.

This is the error message:


  In order for the app to work properly, please enable access to the microphone from your phone settings.


What should be done to make the application work?
The problem is Twilight application which is running, you need only to make stop and then give the permissions to the English application and then you can run the Twilight app.
