so using this microphone with your default camera should capture your audio using the external microphone not using the inbuilt microphone in your mobile phone but if there is a issue that your phone somehow not capturing the external microphone you need to go to your camera settings and see if there is an option to select the external microphone because new smartphone most of them have the options now to connect an external microphone in the default camera so you need to turn it on in the settings but unfortunately if your smartphone don’t have the option in your camera settings to connect the action microphone then you will have to open a third party application you to download it from Play Store and application name is open camera you can let only search it down and install it and inside the settings of open camera you will see an external microphone option where you can record very good videos with different settings.

this is an example of a very simple background that you can use where you can add things like some plant or a white colour wall background with a screen like a television curtains that will give a professional look on your videos and plus at the same time try to use the natural light from coming from the window as your light source because good lighting is what makes a video pops out
