I have a galaxy s5 lifeproof case and have trouble hearing and being muffled sounding to whoever I’m talking to. I’ve tried everything to make sure it’s securely in the case. Still having this problem. How do I know or who do I contact to get a replacement case? Or is that even a possibility? Thanks,
