Issues with microphone.

[Talaya]

The microphone only works when my phone is open at a 90 degree angle. When it's opened flat people only hear static. If I record anything static as well. I have no cover and no issues with the screen.

Mines the same, my flip just does what it wants and when's want, I can't press half the button, it's like someone is controlling it !

Please run the diagnostic tool in your Battery and Device Care Section to see if that highlights anything.

If nkt then you may need to contact a Samsung Service Centre.

If I can be of any further help then please don't hesitate. Take care.  😎
