iphone 7 in pelican case cuts out
I have an iphone 7 in a pelican marine case. I can hear perfectly and the other party can here me clearly most of the time. During some conversations the other party can't hear me talking at all, but I can hear them. Tried a new sim card, that didn't help. When I take the case off it seams to be working fine. Does anyone else have this problem with a pelican case?
