Static sound and crackles.
Sometimes when I go to play sound or use apps on my iphone 5 it just keeps making a static sound or it crackles. This issue is also happening when the phone rings. When I push the power button to wake it and make it go to sleep. I have read it could be LTE issue, But I don't use lte and its not enabled. I have also read that it could be fixed by turning off phone noise cancelation didn't work. I am sure its hardware but not sure what part.
Is this a good question?
